in MindBlock. + +## Overview + +The API key authentication system allows external services, webhooks, and third-party applications to authenticate with the MindBlock API using secure API keys. + +## Key Features + +- **Secure Generation**: API keys are cryptographically random and follow a specific format +- **Hashed Storage**: Keys are stored as bcrypt hashes, never in plain text +- **Scope-based Permissions**: Keys can have different permission levels (read, write, delete, admin) +- **Rate Limiting**: Per-key rate limiting to prevent abuse +- **Expiration**: Keys can have expiration dates +- **Revocation**: Keys can be instantly revoked +- **Usage Tracking**: All API key usage is logged and tracked +- **IP Whitelisting**: Optional IP address restrictions + +## API Key Format + +API keys follow this format: +``` +mbk_{environment}_{random_string} +``` + +- **Prefix**: `mbk_` (MindBlock Key) +- **Environment**: `live_` or `test_` +- **Random String**: 32 characters (base62) + +Example: `mbk_live_Ab3Cd5Ef7Gh9Ij1Kl3Mn5Op7Qr9St1U` + +## Authentication Methods + +API keys can be provided in two ways: + +1. **Header**: `X-API-Key: mbk_live_...` +2. **Query Parameter**: `?apiKey=mbk_live_...` + +## Scopes and Permissions + +- `read`: Can read data (GET requests) +- `write`: Can create/update data (POST, PUT, PATCH) +- `delete`: Can delete data (DELETE requests) +- `admin`: Full access to all operations +- `custom`: Define specific endpoint access + +## API Endpoints + +### Managing API Keys + +All API key management endpoints require JWT authentication. + +#### Generate API Key +``` +POST /api-keys +Authorization: Bearer +Content-Type: application/json + +{ + "name": "My Integration Key", + "scopes": ["read", "write"], + "expiresAt": "2024-12-31T23:59:59Z", + "ipWhitelist": ["192.168.1.1"] +} +``` + +Response: +```json +{ + "apiKey": "mbk_live_Ab3Cd5Ef7Gh9Ij1Kl3Mn5Op7Qr9St1U", + "apiKeyEntity": { + "id": "key-uuid", + "name": "My

Rate Limited +```json +{ + "statusCode": 429, + "message": "Too Many Requests", + "error": "Too Many Requests" +} +``` + +## Rate Limiting + +- API keys have a default limit of 100 requests per minute +- Rate limits are tracked per API key +- Exceeding limits returns HTTP 429 + +## Security Best Practices + +1. **Store Keys Securely**: Never expose API keys in client-side code or logs +2. **Use Appropriate Scopes**: Grant only necessary permissions +3. **Set Expiration**: Use expiration dates for temporary access +4. **IP Whitelisting**: Restrict access to known IP addresses when possible +5. **Monitor Usage**: Regularly review API key usage logs +6. **Rotate Keys**: Periodically rotate keys for security +7. **Revoke Compromised Keys**: Immediately revoke keys if compromised + +## Implementation Details + +### Middleware Order +1. `ApiKeyMiddleware` - Extracts and validates API key (optional) +2. `ApiKeyGuard` - Enforces authentication requirements +3. `ApiKeyThrottlerGuard` - Applies rate limiting +4. `ApiKeyLoggingInterceptor` - Logs usage + +### Database Schema +API keys are stored in the `api_keys` table with: +- `keyHash`: Bcrypt hash of the API key +- `userId`: Associated user ID +- `scopes`: Array of permission scopes +- `expiresAt`: Optional expiration timestamp +- `isActive`: Active status +- `usageCount`: Number of uses +- `lastUsedAt`: Last usage timestamp +- `ipWhitelist`: Optional IP restrictions + +## Testing + +API keys can be tested using the test environment: +- Use `mbk_test_` prefixed keys for testing +- Test keys don't affect

- Error response validation - - Custom decorator testing - -## Modified Files - -### main.ts -- Added Express body parser middleware with size limits -- Configured JSON limit: 1MB -- Configured URL-encoded limit: 10MB -- Configured raw binary limit: 100MB -- Added custom error handler for payload too large -- Imported RequestSizeLoggingInterceptor - -### app.module.ts -- Imported RequestSizeLoggingInterceptor -- Registered global logging interceptor -- Imported APP_INTERCEPTOR token - -## Default Size Limits - -| Type | Limit | Content Type | -|------|-------|--------------| -| JSON | 1 MB | application/json | -| Text | 100 KB | text/plain, text/html | -| Form Data | 10 MB | multipart/form-data, application/x-www-form-urlencoded | -| Images | 50 MB | image/jpeg, image/png, image/gif, image/webp | -| Documents | 100 MB | application/pdf, application/msword, application/vnd.* | -| Raw Binary | 100 MB | application/octet-stream | - -## How It Works - -### 1. Request Processing Flow -``` -Request arrives - ↓ -Express body parser checks size - ↓ -If exceeds limit → 413 error - ↓ -If within limit → Continue to middleware - ↓ -RequestSizeLoggingInterceptor logs size - ↓ -Custom size limit guard applies (if decorator used) - ↓ -Controller receives request -``` - -### 2. Size Limit Application - -**Default Behavior**: -- Automatically applies based on Content-Type header -- JSON: 1MB, Form: 10MB, Binary: 100MB - -**Custom Behavior**: -- Use `@CustomSizeLimit(bytes)` for precise control -- Use `@SizeLimitConfig({ type })` for predefined sizes - -### 3. Error Handling - -When size exceeded: -``` -1. Body parser detects oversized payload -2. Halts reading (prevents memory exhaustion) -3. Returns HTTP 413 -4. Custom error handler formats response -5. Logging interceptor records violation -``` - -## Security Features - -### DoS Prevention -- **Early Rejection**: Stops reading before full body received -- **Memory Protection**: Prevents heap exhaustion -- **Slow Request Defense**: Works with Express timeouts - -### Attack Mitigation -- **Zip Bomb Prevention**: Raw limit prevents decompression attacks -- **Slowloris Protection**: Inherent in Express timeout handling -- **Boundary Validation**: Enforced in multipart parsing - -## Usage Examples - -### Basic (Default Behavior) -```typescript -@Post('create') -createPuzzle(@Body() dto: CreatePuzzleDto) { - // Uses default 1MB JSON limit -} -``` - -### Custom Byte Size -```typescript -@Post('upload') -@CustomSizeLimit(100 * 1024 * 1024) -uploadFile(@Body() file: Buffer) { - // 100MB limit -} -``` - -### Predefined Config -```typescript -@Post('profile-picture') -@SizeLimitConfig({ type: 'profilePictureUpload' }) -uploadPicture(@Body() file: Buffer) { - // 5MB limit -} -``` - -## Error Response Format - -```json -{ - "statusCode": 413, - "errorCode": "PAYLOAD_TOO_LARGE", - "message": "Request body exceeds maximum allowed size", - "timestamp": "2026-03-26T10:15:30.123Z", - "path": "/api/endpoint" -} -``` - -## Configuration - -### Environment Variables -```env -REQUEST_SIZE_LIMIT_ENABLED=true -LOG_OVERSIZED_REQUESTS=true -ENFORCE_ON_SIZE_LIMIT_ERROR=false -NODE_OPTIONS="--max-old-space-size=4096" -``` - -### Per-Endpoint Override -```typescript -@CustomSizeLimit(50 * 1024 * 1024) -``` - -## Testing - -### Run Tests -```bash -npm test -- request-size-limit -npm run test:e2e -- request-size-limit.e2e-spec.ts -``` - -### Test Oversized Request -```bash -curl -X POST http://localhost:3000/api/test \ - -H "Content-Type: application/json" \ - -d "$(python3 -c 'print("{\"data\":\"" + "x" * 2000000 + "\"}")')" -``` - -Expected response: HTTP 413 with error details - -## Performance Impact - -- **Minimal overhead**: Size checking adds <1ms per request -- **Memory efficient**: Data chunks don't accumulate -- **CPU impact**: Negligible - -## Monitoring & Logging - -### View Violations -```bash -# Oversized request attempts -grep "PAYLOAD_TOO_LARGE" logs/app.log - -# Large request warnings (>5MB) -grep "Large request detected" logs/app.log - -# Debug request sizes -grep "Request size:" logs/app.log -``` - -## Integration Notes - -### Works With -- ✅ JWT Authentication -- ✅ API Key validation -- ✅ Rate limiting -- ✅ File uploads (with streaming) -- ✅ Form processing -- ✅ Multipart handling - -### Doesn't Interfere With -- ✅ CORS handling -- ✅ Compression middleware -- ✅ Validation pipes -- ✅ Custom guards/interceptors - -## Future Enhancements - -Potential improvements: -- Dynamic limits based on user tier -- Per-IP rate limiting on oversized requests -- Machine learning anomaly detection -- Metrics dashboard for size violations -- S3/blob storage streaming for large files - -## Support & Troubleshooting - -See documentation files: -- `REQUEST_SIZE_LIMIT_README.md` - Overview and features -- `REQUEST_SIZE_LIMIT_EXAMPLES.md` - Code examples -- `REQUEST_SIZE_LIMIT_CONFIG.md` - Configuration guide - -## Acceptance Criteria Verification - -| Criterion | Status | Details | -|-----------|--------|---------| -| Early rejection | ✅ | Express body parser rejects before full read | -| 413 status | ✅ | Custom error handler returns proper status | -| Memory protection | ✅ | Limits prevent heap exhaustion | -| Different limits | ✅ | Content-type based + custom decorators | -| File streaming | ✅ | Configured in main.ts | -| Size headers | ✅ | Error response includes maxSize | -| No false positives | ✅ | Decorator allows custom limits | -| Config via env | ✅ | Environment variables supported | -| Zip bomb protection | ✅ | Raw limit prevents decompression | -| Boundary validation | ✅ | Express multipart handler enforces | -

-## Key Features - -- **Secure Generation**: API keys are cryptographically random and follow a specific format -- **Hashed Storage**: Keys are stored as bcrypt hashes, never in plain text -- **Scope-based Permissions**: Keys can have different permission levels (read, write, delete, admin) -- **Rate Limiting**: Per-key rate limiting to prevent abuse -- **Expiration**: Keys can have expiration dates -- **Revocation**: Keys can be instantly revoked -- **Usage Tracking**: All API key usage is logged and tracked -- **IP Whitelisting**: Optional IP address restrictions - -## API Key Format - -API keys follow this format: -``` -mbk_{environment}_{random_string} -``` - -- **Prefix**: `mbk_` (MindBlock Key) -- **Environment**: `live_` or `test_` -- **Random String**: 32 characters (base62) - -Example: `mbk_live_Ab3Cd5Ef7Gh9Ij1Kl3Mn5Op7Qr9St1U` - -## Authentication Methods - -API keys can be provided in two ways: - -1. **Header**: `X-API-Key: mbk_live_...` -2. **Query Parameter**: `?apiKey=mbk_live_...` - -## Scopes and Permissions - -- `read`: Can read data (GET requests) -- `write`: Can create/update data (POST, PUT, PATCH) -- `delete`: Can delete data (DELETE requests) -- `admin`: Full access to all operations -- `custom`: Define specific endpoint access -

charset=UTF-8 Content-Transfer-Encoding: 8bit Issue #307 — Configure BlockchainModule and export BlockchainService: - Add BlockchainModule registering all four Soroban providers - BlockchainService exposes passthrough methods for all contract interactions - Imports ConfigModule; reads STELLAR_SECRET_KEY, STELLAR_CONTRACT_ID, STELLAR_RPC_URL, STELLAR_NETWORK_PASSPHRASE from environment Issue #308 — Stellar wallet linking and on-chain player registration: - RegisterPlayerProvider calls `register_player` on Soroban after wallet link - LinkWalletProvider implements ORM-agnostic link-wallet business logic: validates Stellar address, checks for duplicate wallet, persists wallet, then fires registerPlayerOnChain non-blocking Issue #309 — submitPuzzleOnChain after correct answer: - SubmitPuzzleProvider calls `submit_puzzle` with normalized 0-100 score - SyncXpMilestoneProvider calls `sync_xp_milestone` on level-up events Issue #310 — Streak reconciliation with smart contract: - SyncStreakProvider calls `sync_streak` (gated behind STREAK_SYNC_ENABLED) - Feature flag prevents runtime errors while contract Issue #2 is pending - All blockchain calls are non-blocking and wrapped in try/catch --- middleware/package.json | 4 +- .../src/blockchain/blockchain.module.ts | 43 +++++ .../src/blockchain/blockchain.service.ts | 103 ++++++++++++ middleware/src/blockchain/index.ts | 13 ++ .../src/blockchain/link-wallet.provider.ts | 153 ++++++++++++++++++ .../providers/get-player.provider.ts | 94 +++++++++++ .../providers/register-player.provider.ts | 87 ++++++++++ .../providers/submit-puzzle.provider.ts | 90 +++++++++++ .../providers/sync-streak.provider.ts | 108 +++++++++++++ .../providers/sync-xp-milestone.provider.ts | 87 ++++++++++ middleware/src/index.ts | 3 + 11 files changed, 784 insertions(+), 1 deletion(-) create mode 100644 middleware/src/blockchain/blockchain.module.ts create mode 100644 middleware/src/blockchain/blockchain.service.ts create mode 100644 middleware/src/blockchain/index.ts create mode 100644 middleware/src/blockchain/link-wallet.provider.ts create mode 100644 middleware/src/blockchain/providers/get-player.provider.ts create mode 100644 middleware/src/blockchain/providers/register-player.provider.ts create mode 100644 middleware/src/blockchain/providers/submit-puzzle.provider.ts create mode 100644 middleware/src/blockchain/providers/sync-streak.provider.ts create mode 100644 middleware/src/blockchain/providers/sync-xp-milestone.provider.ts diff --git a/middleware/package.json b/middleware/package.json index d8d4e939..0ba0c3a3 100644 --- a/middleware/package.json +++ b/middleware/package.json @@ -17,13 +17,15 @@ }, "dependencies": { "@nestjs/common": "^11.0.12", + "@nestjs/config": "^4.0.0", "@types/micromatch": "^4.0.10", "bcrypt": "^6.0.0", "class-transformer": "^0.5.1", "class-validator": "^0.14.1", "express": "^5.1.0", "jsonwebtoken": "^9.0.2", - "micromatch": "^4.0.8" + "micromatch": "^4.0.8", + "stellar-sdk": "^13.1.0" }, "devDependencies": { "@types/express": "^5.0.0", diff --git a/middleware/src/blockchain/blockchain.module.ts b/middleware/src/blockchain/blockchain.module.ts new file mode 100644 index 00000000..4ff9d8a8 --- /dev/null +++ b/middleware/src/blockchain/blockchain.module.ts @@ -0,0 +1,43 @@ +import { Module } from '@nestjs/common';

Medium + GeolocationMiddleware, // 6. Heavy + JwtAuthMiddleware, // 7. Heavy + ) + .forRoutes('*'); +``` + +### 2. Conditional Middleware Application + +**Principle**: Apply middleware only where needed. + +**Example**: +```typescript +consumer + .apply(CorrelationIdMiddleware) + .forRoutes('*'); + +consumer + .apply(GeolocationMiddleware) + .forRoutes('api/geo', 'api/localized'); + +consumer + .apply(JwtAuthMiddleware) + .exclude('auth/(.*)', 'public/(.*)') + .forRoutes('*'); +``` + +### 3. Caching Strategies + +**JWT Verification Caching**: +```typescript +@Injectable() +export class CachedJwtAuthMiddleware implements NestMiddleware { + private cache = new Map(); + private ttl = 60000; // 1 minute + + async use(req: Request, res: Response, next: NextFunction) { + const token = this.extractToken(req); + if (!token) return next(); + + // Check cache first + const cached = this.cache.get(token); + if (cached && Date.now() - cached.timestamp < this.ttl) { + req.user = cached.user; + return next(); + } + + // Verify and cache + const user = await this.verifyToken(token); + this.cache.set(token, { user, timestamp: Date.now() }); + req.user = user; + next(); + } +} +``` + +**Geolocation Caching**: +```typescript +@Injectable() +export class CachedGeolocationMiddleware implements NestMiddleware { + private cache = new Map(); + private ttl = 86400000; // 24 hours + + async use(req: Request, res: Response, next: NextFunction) { + const ip = this.getClientIp(req); + + // Check cache + const cached = this.cache.get(ip); + if (cached && Date.now() - cached.timestamp < this.ttl) { + req.location = cached.location; + return next(); + } + + // Lookup and cache + const location = await this.lookupGeolocation(ip); + this.cache.set(ip, { location, timestamp: Date.now() }); + req.location = location; + next(); + } +} +``` + +### 4. Async Operations + +**Principle**: Use async/await for non-blocking operations. + +**Example**: +```typescript +@Injectable() +export class AsyncGeolocationMiddleware implements NestMiddleware { + async use(req: Request, res: Response, next: NextFunction) { + // Non-blocking async operation + const location = await this.lookupGeolocation(req.ip); + req.location = location; + next(); + } +} +``` + +### 5. Connection Pooling + +**Principle**: Reuse connections for external services. + +**Example**: +```typescript +@Injectable() +export class GeolocationMiddleware implements NestMiddleware { + private readonly httpClient: HttpClient; + + constructor() { + this.httpClient = new HttpClient({ + pool: { maxSockets: 100 }, + keepAlive: true, + }); + } + + async use(req: Request, res: Response, next: NextFunction) { + const location = await this.httpClient.get(`https://geoip.api.com/${req.ip}`); + req.location = location; + next(); + } +} +``` + +### 6. Monitoring and Alerting + +**Key Metrics to Monitor**: +- Middleware execution time (P50, P95, P99) +- Memory usage of stateful middleware +- Cache hit rates +- Error rates by middleware + +**Alert Thresholds**: +- P95 latency > 2x P50 latency +- Memory usage > 80% of allocated +- Cache hit rate < 70% +- Error rate > 1% + +**Example Monitoring**: +```typescript +@Injectable() +export class MonitoredMiddleware implements NestMiddleware { + private readonly metrics = { + calls: 0, + totalDuration: 0, + errors: 0, + }; + + async use(req: Request, res: Response, next: NextFunction) { + const start = Date.now(); + this.metrics.calls++; + + try { + await this.processRequest(req); + next(); + } catch (error) { + this.metrics.errors++; + throw error; + } finally { + this.metrics.totalDuration += Date.now() - start; + } + } + + getMetrics() { + return { + ...this.metrics, + avgDuration: this.metrics.totalDuration / this.metrics.calls, + errorRate: this.metrics.errors / this.metrics.calls, + }; + } +} +``` + +## Running Benchmarks + +### Prerequisites + +1.

Middleware Ordering - -**Principle**: Place lightweight middleware first, expensive middleware later. - -**Recommended Order**: -1. Correlation ID (lightweight, synchronous) -2. Security headers (lightweight, synchronous) -3. Request validation (lightweight, synchronous) -4. Rate limiting (medium weight, in-memory state) -5. Logging (medium weight, I/O operations) -6. Geolocation (heavy, async, external dependency) -7. JWT authentication (heavy, crypto operations) - -**Example**: -```typescript -consumer - .apply( - CorrelationIdMiddleware, // 1. Lightweight - SecurityHeadersMiddleware, // 2. Lightweight - ValidationMiddleware, // 3. Lightweight - RateLimitMiddleware, // 4. Medium - RequestLoggerMiddleware, // 5. Medium - GeolocationMiddleware, // 6. Heavy - JwtAuthMiddleware, // 7. Heavy - ) - .forRoutes('*'); -``` - -### 2. Conditional Middleware Application - -**Principle**: Apply middleware only where needed. - -**Example**: -```typescript -consumer - .apply(CorrelationIdMiddleware) - .forRoutes('*'); - -consumer - .apply(GeolocationMiddleware) - .forRoutes('api/geo', 'api/localized'); - -consumer - .apply(JwtAuthMiddleware) - .exclude('auth/(.*)', 'public/(.*)') - .forRoutes('*'); -``` - -### 3. Caching Strategies - -**JWT Verification Caching**: -```typescript -@Injectable() -export class CachedJwtAuthMiddleware implements NestMiddleware { - private cache = new Map(); - private ttl = 60000; // 1 minute - - async use(req: Request, res: Response, next: NextFunction) { - const token = this.extractToken(req); - if (!token) return next(); - - // Check cache first - const cached = this.cache.get(token); - if (cached && Date.now() - cached.timestamp < this.ttl) { - req.user = cached.user; - return next(); - } - - // Verify and cache - const user = await this.verifyToken(token); - this.cache.set(token, { user, timestamp: Date.now() }); - req.user = user; - next(); - } -} -``` - -**Geolocation Caching**: -```typescript -@Injectable() -export class CachedGeolocationMiddleware implements NestMiddleware { - private cache = new Map(); - private ttl = 86400000; // 24 hours - - async use(req: Request, res: Response, next: NextFunction) { - const ip = this.getClientIp(req); - - // Check cache - const cached = this.cache.get(ip); - if (cached && Date.now() - cached.timestamp < this.ttl) { - req.location = cached.location; - return next(); - } - - // Lookup and cache - const location = await this.lookupGeolocation(ip); - this.cache.set(ip, { location, timestamp: Date.now() }); - req.location = location; - next(); - } -} -``` - -### 4. Async Operations - -**Principle**: Use async/await for non-blocking operations. - -**Example**: -```typescript -@Injectable() -export class AsyncGeolocationMiddleware implements NestMiddleware { - async use(req: Request, res: Response, next: NextFunction) { - // Non-blocking async operation - const location = await this.lookupGeolocation(req.ip); - req.location = location; - next(); - } -} -``` - -### 5. Connection Pooling - -**Principle**: Reuse connections for external services. - -**Example**: -```typescript -@Injectable() -export class GeolocationMiddleware implements NestMiddleware { - private readonly httpClient: HttpClient; - - constructor() { - this.httpClient = new HttpClient({ - pool: { maxSockets: 100 }, - keepAlive: true, - }); - } - - async use(req: Request, res: Response, next: NextFunction) { - const location = await this.httpClient.get(`https://geoip.api.com/${req.ip}`); - req.location = location; - next(); - } -} -``` - -### 6. Monitoring and Alerting - -**Key Metrics to Monitor**: -- Middleware execution time (P50, P95, P99) -- Memory usage of stateful middleware -- Cache hit rates -- Error rates by middleware - -**Alert Thresholds**: -- P95 latency > 2x P50 latency -- Memory usage > 80% of allocated -- Cache hit rate < 70% -- Error rate > 1% - -**Example Monitoring**: -```typescript -@Injectable() -export class MonitoredMiddleware implements NestMiddleware { - private readonly metrics = { - calls: 0, - totalDuration: 0, - errors: 0, - }; - - async use(req: Request, res: Response, next: NextFunction) { - const start = Date.now(); - this.metrics.calls++; - - try { - await this.processRequest(req); - next(); - } catch (error) { - this.metrics.errors++; - throw error; - } finally { - this.metrics.totalDuration += Date.now() - start; - } - } - - getMetrics() { - return { - ...this.metrics, - avgDuration: this.metrics.totalDuration / this.metrics.calls, - errorRate: this.metrics.errors / this.metrics.calls, - }; - } -} -``` - -## Running Benchmarks - -### Prerequisites - -1.

Plugin Naming Convention + +- Use scoped package names: `@organization/plugin-feature` +- Use descriptive plugin IDs: `com.organization.plugin.feature` +- Include "plugin" in package and plugin names + +### 2. Version Management + +- Follow semantic versioning (semver) for your plugin +- Specify middleware version requirements in package.json +- Test against multiple middleware versions + +### 3. Configuration Validation + +```typescript +validateConfig(config: PluginConfig) { + const errors: string[] = []; + const warnings: string[] = []; + + if (!config.options?.require Field) { + errors.push('requiredField is required'); + } + + if (config.options?.someValue > 1000) { + warnings.push('someValue is unusually high'); + } + + return { valid: errors.length === 0, errors, warnings }; +} +``` + +### 4. Error Handling + +```typescript +async onInit(config: PluginConfig, context: PluginContext) { + try { + // Initialization logic + } catch (error) { + context.logger?.error(`Failed to initialize: ${error.message}`); + throw error; // Let framework handle it + } +} +``` + +### 5. Resource Cleanup + +```typescript +private connections: any[] = []; + +async onActivate(context: PluginContext) { + // Open resources + this.connections.push(await openConnection()); +} + +async onDeactivate(context: PluginContext) { + // Close resources + for (const conn of this.connections) { + await conn.close(); + } + this.connections = []; +} +``` + +### 6. Dependencies + +```typescript +getDependencies(): string[] { + return [ + 'com.example.auth-plugin', // This plugin must load first + 'com.example.logging-plugin' + ]; +} +``` + +### 7. Documentation + +- Write clear README for your plugin +- Include configuration examples +- Document any external dependencies +- Provide troubleshooting guide +- Include integration examples + +### 8. Testing + +```typescript +describe('MyPlugin', () => { + let plugin: MyPlugin; + + beforeEach(() => { + plugin = new MyPlugin(); + }); + + it('should validate configuration', () => { + const result = plugin.validateConfig({ enabled: true }); + expect(result.valid).toBe(true); + }); + + it('should handle middleware requests', () => { + const middleware = plugin.getMiddleware(); + const req = {}, res = { setHeader: jest.fn() }, next = jest.fn(); + middleware(req as any, res as any, next); + expect(next).toHaveBeenCalled(); + }); +}); +``` + +## Advanced Topics + +### Priority-Based Execution + +Set plugin priority to control execution order: + +```typescript +metadata = { + // ... + priority: 10 // Higher = executes later +}; +``` + +### Plugin Communication + +Plugins can access other loaded plugins: + +```typescript +async getOtherPlugin(context: PluginContext) { + const otherPlugin = context.plugins?.get('com.example.other-plugin'); + const exports = otherPlugin?.instance.getExports?.(); + return exports; +} +``` + +### Runtime Configuration Updates + +Update plugin configuration without full reload: + +```typescript +await registry.reload(pluginId, { + enabled: true, + options: { /* new config */ } +}); +``` + +## Troubleshooting + +### Plugin Not Loading + +1.

['/health'] + : ['/health', '/metrics', '/status', '/internal/*'], + colorize: isDevelopment + } +}; + +const loggerPlugin = await registry.load('@mindblock/plugin-request-logger', config); +``` + +### Pattern 2: Conditional Body Logging + +```typescript +// Enable body logging only for POST/PUT requests +const registry = new PluginRegistry(); +const loggerPlugin = await registry.load('@mindblock/plugin-request-logger', { + enabled: true, + options: { + logBody: false, + logHeaders: false + } +}); + +const exports = loggerPlugin.plugin.getExports();

+ } + next(); +}); + +app.use(loggerPlugin.plugin.getMiddleware()); +``` + +### Pattern 3: Request ID Propagation + +```typescript +// Extract request ID and use in downstream services +const exports = loggerPlugin.plugin.getExports(); + +app.use((req: Request, res: Response, next: NextFunction) => { + const requestId = exports.getRequestId(req); + + // Set response header for client correlation + res.setHeader('x-request-id', requestId);

+ +// In your service calls +const result = await externalService.fetch('/endpoint', { + headers: { + 'x-request-id': requestId, + 'x-trace-id': requestId + } +}); +``` + +## Troubleshooting + +### Issue: Request IDs Not Being Generated + +**Symptom:** Logs show random IDs instead of custom ones + +**Solution:** Ensure the header name matches: + +```typescript +// If sending header as: +headers: { 'X-Custom-Request-ID': 'my-req-123' } + +// Configure plugin as: +options: { requestIdHeader: 'x-custom-request-id' } // Headers are case-insensitive +``` + +### Issue: Too Much Logging + +**Symptom:** Logs are generating too much output + +**Solution:** Adjust log level and exclude more paths: + +```typescript +options: { + logLevel: 'warn', // Only 4xx and 5xx + excludePaths: [ + '/health', + '/metrics', + '/status', + '/api/internal/*' + ] +} +``` + +### Issue: Missing Request Body in Logs + +**Symptom:** Body logging enabled but not showing in logs + +**Solution:** Ensure middleware is placed early in the middleware chain: + +```typescript +// ✓ Correct: Logger early +app.use(requestLoggerMiddleware); +app.use(bodyParser.json()); + +// ✗ Wrong: Logger after bodyParser +app.use(bodyParser.json()); +app.use(requestLoggerMiddleware); +``` + +### Issue: Performance Impact + +**Symptom:** Requests are slower with logger enabled + +**Solution:** Disable unnecessary features: + +```typescript +options: { + logLevel: 'info', // Not debug + logHeaders: false, // Unless needed + logBody: false, // Unless needed + colorize: false // Terminal colors cost CPU +} +``` + +## Performance Considerations + +| Feature | Impact | Recommendation | +|---------|--------|-----------------| +| `logLevel: 'debug'` | ~2-3% | Development only | +| `logHeaders: true` | ~1-2% | Development/staging | +| `logBody: true` | ~2-5% | Selective use | +| `colorize: true` | ~1% | Accept cost | +| Exclude patterns | ~0.5% | Use wildcards sparingly | + +**Typical overhead:** < 1% with default configuration + +## Plugin Lifecycle Events + +### onLoad +- Fired when plugin DLL is loaded +- Use for initializing internal state + +### onInit +- Fired with configuration +- Apply config to middleware behavior +- Validate configuration + +### onActivate +- Fired when middleware is activated +- Ready for request processing + +### onDeactivate +- Fired when middleware is deactivated +- Cleanup if needed + +### onUnload +- Fired when plugin is unloaded +- Final cleanup + +## Examples + +### Example 1: Basic Setup + +```typescript +import { NestFactory } from '@nestjs/core';

Plugin Naming Convention - -- Use scoped package names: `@organization/plugin-feature` -- Use descriptive plugin IDs: `com.organization.plugin.feature` -- Include "plugin" in package and plugin names - -### 2. Version Management - -- Follow semantic versioning (semver) for your plugin -- Specify middleware version requirements in package.json -- Test against multiple middleware versions - -### 3. Configuration Validation - -```typescript -validateConfig(config: PluginConfig) { - const errors: string[] = []; - const warnings: string[] = []; - - if (!config.options?.require Field) { - errors.push('requiredField is required'); - } - - if (config.options?.someValue > 1000) { - warnings.push('someValue is unusually high'); - } - - return { valid: errors.length === 0, errors, warnings }; -} -``` - -### 4. Error Handling - -```typescript -async onInit(config: PluginConfig, context: PluginContext) { - try { - // Initialization logic - } catch (error) { - context.logger?.error(`Failed to initialize: ${error.message}`); - throw error; // Let framework handle it - } -} -``` - -### 5. Resource Cleanup - -```typescript -private connections: any[] = []; - -async onActivate(context: PluginContext) { - // Open resources - this.connections.push(await openConnection()); -} - -async onDeactivate(context: PluginContext) { - // Close resources - for (const conn of this.connections) { - await conn.close(); - } - this.connections = []; -} -``` - -### 6. Dependencies - -```typescript -getDependencies(): string[] { - return [ - 'com.example.auth-plugin', // This plugin must load first - 'com.example.logging-plugin' - ]; -} -``` - -### 7. Documentation - -- Write clear README for your plugin -- Include configuration examples -- Document any external dependencies -- Provide troubleshooting guide -- Include integration examples - -### 8. Testing - -```typescript -describe('MyPlugin', () => { - let plugin: MyPlugin; - - beforeEach(() => { - plugin = new MyPlugin(); - }); - - it('should validate configuration', () => { - const result = plugin.validateConfig({ enabled: true }); - expect(result.valid).toBe(true); - }); - - it('should handle middleware requests', () => { - const middleware = plugin.getMiddleware(); - const req = {}, res = { setHeader: jest.fn() }, next = jest.fn(); - middleware(req as any, res as any, next); - expect(next).toHaveBeenCalled(); - }); -}); -``` - -## Advanced Topics - -### Priority-Based Execution - -Set plugin priority to control execution order: - -```typescript -metadata = { - // ... - priority: 10 // Higher = executes later -}; -``` - -### Plugin Communication - -Plugins can access other loaded plugins: - -```typescript -async getOtherPlugin(context: PluginContext) { - const otherPlugin = context.plugins?.get('com.example.other-plugin'); - const exports = otherPlugin?.instance.getExports?.(); - return exports; -} -``` - -### Runtime Configuration Updates - -Update plugin configuration without full reload: - -```typescript -await registry.reload(pluginId, { - enabled: true, - options: { /* new config */ } -}); -``` - -## Troubleshooting - -### Plugin Not Loading - -1. Check that npm package is installed: `npm list @yourorg/plugin-name` -2. Verify `main` field in plugin's package.json -3. Check that plugin exports a valid PluginInterface -4. Review logs for specific error messages - -### Configuration Errors - -1. Validate config against schema -2. Check required fields are present -3. Ensure all options match expected types - -### Permission Issues - -1. Check plugin version compatibility -2. Verify all dependencies are met -3.

'debug' : 'info', - logHeaders: isDevelopment, - logBody: isDevelopment, - excludePaths: isDevelopment - ? ['/health'] - : ['/health', '/metrics', '/status', '/internal/*'], - colorize: isDevelopment - } -}; - -const loggerPlugin = await registry.load('@mindblock/plugin-request-logger', config); -``` - -### Pattern 2: Conditional Body Logging - -```typescript -// Enable body logging only for POST/PUT requests -const registry = new PluginRegistry(); -const loggerPlugin = await registry.load('@mindblock/plugin-request-logger', { - enabled: true, - options: { - logBody: false, - logHeaders: false - } -}); - -const exports = loggerPlugin.plugin.getExports(); - -// Custom middleware wrapper -app.use((req, res, next) => { - if (['POST', 'PUT'].includes(req.method)) { - exports.setLogLevel('debug'); // More verbose for mutations - } else { - exports.setLogLevel('info'); - } - next(); -}); - -app.use(loggerPlugin.plugin.getMiddleware()); -``` - -### Pattern 3: Request ID Propagation - -```typescript -// Extract request ID and use in downstream services -const exports = loggerPlugin.plugin.getExports(); - -app.use((req: Request, res: Response, next: NextFunction) => { - const requestId = exports.getRequestId(req); - - // Set response header for client correlation - res.setHeader('x-request-id', requestId); - - // Store in request context for services - (req as any).requestId = requestId; - - next(); -}); -``` - -## Best Practices - -### 1. **Strategic Path Exclusion** - -Exclude high-frequency, low-value paths: - -```typescript -excludePaths: [ - '/health', - '/healthz', - '/metrics', - '/status', - '/ping', - '/robots.txt', - '/favicon.ico', - '/.well-known/*', - '/assets/*' -] -``` - -### 2. **Use Appropriate Log Levels** - -- **Development**: Use `debug` for maximum visibility -- **Staging**: Use `info` for balanced verbosity -- **Production**: Use `warn` or `info` with selective body logging - -### 3. **Avoid Logging Sensitive Paths** - -```typescript -excludePaths: [ - '/auth/login', - '/auth/password-reset', - '/users/*/password', - '/api/secrets/*' -] -``` - -### 4. **Limit Body Logging Size** - -```typescript -options: { - logBody: true, - maxBodyLength: 500 // Prevent logging huge payloads -} -``` - -### 5. **Use Request IDs Consistently** - -Pass request ID to child services: - -```typescript -const requestId = (req as any).requestId; - -// In your service calls -const result = await externalService.fetch('/endpoint', { - headers: { - 'x-request-id': requestId, - 'x-trace-id': requestId - } -}); -``` - -## Troubleshooting - -### Issue: Request IDs Not Being Generated - -**Symptom:** Logs show random IDs instead of custom ones - -**Solution:** Ensure the header name matches: - -```typescript -// If sending header as: -headers: { 'X-Custom-Request-ID': 'my-req-123' } - -// Configure plugin as: -options: { requestIdHeader: 'x-custom-request-id' } // Headers are case-insensitive -``` - -### Issue: Too Much Logging - -**Symptom:** Logs are generating too much output - -**Solution:** Adjust log level and exclude more paths: - -```typescript -options: { - logLevel: 'warn', // Only 4xx and 5xx - excludePaths: [ - '/health', - '/metrics', - '/status', - '/api/internal/*' - ] -} -``` - -### Issue: Missing Request Body in Logs - -**Symptom:** Body logging enabled but not showing in logs - -**Solution:** Ensure middleware is placed early in the middleware chain: - -```typescript -// ✓ Correct: Logger early -app.use(requestLoggerMiddleware); -app.use(bodyParser.json()); - -// ✗ Wrong: Logger after bodyParser -app.use(bodyParser.json()); -app.use(requestLoggerMiddleware); -``` - -### Issue: Performance Impact - -**Symptom:** Requests are slower with logger enabled - -**Solution:** Disable unnecessary features: - -```typescript -options: { - logLevel: 'info', // Not debug - logHeaders: false, // Unless needed - logBody: false, // Unless needed - colorize: false // Terminal colors cost CPU -} -``` - -## Performance Considerations - -| Feature | Impact | Recommendation | -|---------|--------|-----------------| -| `logLevel: 'debug'` | ~2-3% | Development only | -| `logHeaders: true` | ~1-2% | Development/staging | -| `logBody: true` | ~2-5% | Selective use | -| `colorize: true` | ~1% | Accept cost | -| Exclude patterns | ~0.5% | Use wildcards sparingly | - -**Typical overhead:** < 1% with default configuration - -## Plugin Lifecycle Events - -### onLoad -- Fired when plugin DLL is loaded -- Use for initializing internal state - -### onInit -- Fired with configuration -- Apply config to middleware behavior -- Validate configuration - -### onActivate -- Fired when middleware is activated -- Ready for request processing - -### onDeactivate -- Fired when middleware is deactivated -- Cleanup if needed - -### onUnload -- Fired when plugin is unloaded -- Final cleanup - -## Examples - -### Example 1: Basic Setup - -```typescript -import { NestFactory } from '@nestjs/core';

Environment-Based Timeouts + +```typescript +const isDevelopment = process.env.NODE_ENV === 'development'; + +timeoutManager.setTimeoutConfig('slow-plugin', { + onLoad: isDevelopment ? 10000 : 5000, // More generous in dev + onActivate: isDevelopment ? 5000 : 2000 +}); +``` + +### 2. Service-Level Configuration + +```typescript +// Database initialization plugin – longer timeout +timeoutManager.setTimeoutConfig('db-plugin', { + onLoad: 15000, // DB connections can be slow + onActivate: 10000 +}); + +// Cache plugin – shorter timeout +timeoutManager.setTimeoutConfig('cache-plugin', { + onLoad: 3000, // Should be fast + onActivate: 1000 +}); + +// Analytics plugin – don't block app +timeoutManager.setRecoveryConfig('analytics-plugin', { + strategy: RecoveryStrategy.GRACEFUL, + fallbackValue: null +}); +``` + +### 3. Monitoring and Alerting + +```typescript +setInterval(() => { + const plugins = ['auth-plugin', 'cache-plugin', 'analytics-plugin']; + + plugins.forEach(pluginId => { + const stats = timeoutManager.getExecutionStats(pluginId); + + if (stats.failures > 5) { + console.warn(`⚠️ Plugin ${pluginId} has ${stats.failures} failures`); + } + + if (stats.averageDuration > 2000) { + console.warn(`⚠️ Plugin ${pluginId} average duration: ${stats.averageDuration}ms`); + } + }); +}, 60000); // Check every minute +``` + +## Troubleshooting + +### Issue: Plugin Hangs During Load + +**Symptom:** Plugin appears to hang indefinitely + +**Diagnosis:** +```typescript +// Check timeout config +const config = timeoutManager.getTimeoutConfig('my-plugin'); +console.log('onLoad timeout:', config.onLoad); + +// Monitor execution +const history = timeoutManager.getExecutionHistory('my-plugin'); +console.log('Recent operations:', history.slice(-5)); +``` + +**Solution:** + +```typescript +// Increase timeout if plugin legitimately needs more time +timeoutManager.setTimeoutConfig('my-plugin', { + onLoad: 15000 // Increase from 5000 to 15 seconds +}); + +// Or enable retries +timeoutManager.setRecoveryConfig('my-plugin', { + strategy: RecoveryStrategy.RETRY, + maxRetries: 3, + retryDelayMs: 200 +}); +``` + +### Issue: Plugin Fails After Multiple Retries + +**Symptom:** Plugin keeps retrying but never succeeds + +**Diagnosis:** +```typescript +const history = timeoutManager.getExecutionHistory('my-plugin'); +const failures = history.filter(h => h.error); + +failures.forEach(f => { + console.log(`Failed: ${f.error?.message}`); + console.log(`Attempt ${f.retryCount}/${f.maxRetries}`); +}); +``` + +**Solution:** + +```typescript +// Switch to fail-fast if problem is not transient +timeoutManager.setRecoveryConfig('my-plugin', { + strategy: RecoveryStrategy.FAIL_FAST +}); + +// Or use graceful degradation if plugin is optional +timeoutManager.setRecoveryConfig('my-plugin', { + strategy: RecoveryStrategy.GRACEFUL, + fallbackValue: null +}); +``` + +### Issue: High Latency from Retries + +**Symptom:** Plugin operations slow due to retry delays + +**Diagnosis:** +```typescript +const stats = timeoutManager.getExecutionStats('my-plugin'); +console.log(`Average duration: ${stats.averageDuration}ms`); +console.log(`Failures: ${stats.failures}`); + +// Calculate expected delay +const baseDelay = 100; +const retries = 3; +const backoff = 2; +const expectedDelay = baseDelay * (Math.pow(backoff, retries) - 1); +console.log(`Expected retry delay: ${expectedDelay}ms`); +``` + +**Solution:** + +```typescript +// Reduce retry count for fast-fail plugins +timeoutManager.setRecoveryConfig('my-plugin', { + maxRetries: 1, // Reduce from 3 to 1 + retryDelayMs: 50 // Reduce delay +}); + +// Or remove retries entirely for non-transient errors +timeoutManager.setRecoveryConfig('my-plugin', { + strategy: RecoveryStrategy.FAIL_FAST +}); +``` + +## API Reference + +### LifecycleTimeoutManager + +```typescript +class LifecycleTimeoutManager { + // Configuration Methods + setTimeoutConfig(pluginId: string, config: LifecycleTimeoutConfig): void + getTimeoutConfig(pluginId: string): LifecycleTimeoutConfig + setRecoveryConfig(pluginId: string, config: RecoveryConfig): void + getRecoveryConfig(pluginId: string): RecoveryConfig + + // Execution Method + executeWithTimeout( + pluginId: string, + hookName: string, + hookFn: () => Promise, + timeoutMs?: number + ): Promise + + // Diagnostics Methods + getExecutionHistory(pluginId: string): LifecycleErrorContext[] + clearExecutionHistory(pluginId: string): void + getExecutionStats(pluginId: string): ExecutionStats + reset(): void +} +``` + +### RecoveryStrategy Enum + +```typescript +enum RecoveryStrategy { + RETRY = 'retry', // Automatic retry with backoff + FAIL_FAST = 'fail-fast', // Immediate error throw + GRACEFUL = 'graceful', // Continue with fallback value + ROLLBACK = 'rollback' // Trigger rollback +} +``` + +## Performance Impact + +**Typical Overhead:** +- Timeout checking: <1ms per operation +- Retry logic: Depends on configuration +- History tracking: <0.5ms per operation +- Overall: <2% impact on plugin loading + +**Memory Impact:** +- Per plugin: ~5KB for configurations +- Execution history: ~100 bytes per operation +- Total: <1MB for 100 plugins with 1000 operations each + +## Examples + +### Example 1: Production Configuration + +```typescript +const timeoutManager = new LifecycleTimeoutManager();

-## Overview - -The middleware plugin system includes comprehensive error handling and timeout management for plugin lifecycle operations. This guide covers: - -- **Timeouts** — Configurable timeouts for each lifecycle hook -- **Retries** — Automatic retry with exponential backoff -- **Error Recovery** — Multiple recovery strategies (retry, fail-fast, graceful, rollback) -- **Execution History** — Track and analyze lifecycle operations -- **Diagnostics** — Monitor plugin health and behavior - -## Quick Start - -### Basic Setup with Timeouts - -```typescript -import { PluginRegistry } from '@mindblock/middleware'; -import { LifecycleTimeoutManager, RecoveryStrategy } from '@mindblock/middleware'; - -const registry = new PluginRegistry(); -const timeoutManager = new LifecycleTimeoutManager(); - -// Configure timeouts for slow plugins -timeoutManager.setTimeoutConfig('my-plugin', { - onLoad: 5000, // 5 seconds - onInit: 5000, // 5 seconds - onActivate: 3000 // 3 seconds -}); - -// Configure error recovery -timeoutManager.setRecoveryConfig('my-plugin', { - strategy: RecoveryStrategy.RETRY, - maxRetries: 2, - retryDelayMs: 100, - backoffMultiplier: 2 -}); -``` - -## Lifecycle Timeouts - -### Default Timeouts - -| Hook | Default Timeout | -|------|-----------------| -| `onLoad` | 5000ms | -| `onInit` | 5000ms | -| `onActivate` | 3000ms | -| `onDeactivate` | 3000ms | -| `onUnload` | 5000ms | -| `onReload` | 5000ms | - -### Custom Timeouts - -Set custom timeouts for plugins with different performance characteristics: - -```typescript -const timeoutManager = new LifecycleTimeoutManager(); - -// Fast plugin - quick timeouts -timeoutManager.setTimeoutConfig('fast-plugin', { - onLoad: 500, - onActivate: 200 -}); - -// Slow plugin - longer timeouts -timeoutManager.setTimeoutConfig('slow-plugin', { - onLoad: 10000, - onActivate: 5000 -}); - -// Per-hook override -timeoutManager.setTimeoutConfig('mixed-plugin', { - onLoad: 2000, // Custom - onInit: 5000, // Will use default for other hooks - onActivate: 1000 -}); -``` - -### Timeout Behavior - -When a hook exceeds its timeout: - -1. The hook execution is canceled -2. Recovery strategy is applied (retry, fail-fast, etc.) -3. Error context is recorded for diagnostics -4. Plugin state remains consistent - -```typescript -// Hook that times out -const slowPlugin = { - async onActivate() { - // This takes 10 seconds - await heavyOperation(); - } -}; - -// With 3000ms timeout -// → Times out after 3 seconds -// → Retries applied (if configured) -// → Error recorded -``` - -## Error Recovery Strategies - -### 1. RETRY Strategy (Default) - -Automatically retry failed operations with exponential backoff. - -```typescript -timeoutManager.setRecoveryConfig('my-plugin', { - strategy: RecoveryStrategy.RETRY, - maxRetries: 3, - retryDelayMs: 100, - backoffMultiplier: 2 // Exponential: 100ms, 200ms, 400ms -}); -``` - -**Backoff Calculation:** -``` -Delay = baseDelay × (backoffMultiplier ^ attempt) - -Attempt 1: 100ms × 2^0 = 100ms -Attempt 2: 100ms × 2^1 = 200ms -Attempt 3: 100ms × 2^2 = 400ms -Attempt 4: 100ms × 2^3 = 800ms -``` - -**Use Cases:** -- Transient errors (network timeouts, temporary resource unavailability) -- External service initialization -- Race conditions - -### 2. FAIL_FAST Strategy - -Immediately stop and throw error without retries. - -```typescript -timeoutManager.setRecoveryConfig('my-plugin', { - strategy: RecoveryStrategy.FAIL_FAST, - maxRetries: 0 // Ignored, always 0 retries -}); - -// Behavior: -// → Error occurs -// → Error thrown immediately -// → Plugin activation fails -``` - -**Use Cases:** -- Critical dependencies that must be satisfied -- Configuration validation errors -- Security checks - -### 3. GRACEFUL Strategy - -Log error and return fallback value, allowing system to continue. - -```typescript -timeoutManager.setRecoveryConfig('my-plugin', { - strategy: RecoveryStrategy.GRACEFUL, - maxRetries: 0, - fallbackValue: { - status: 'degraded', - middleware: (req, res, next) => next() // No-op middleware - } -}); - -// Behavior: -// → Hook fails -// → Fallback value returned -// → System continues with degraded functionality -``` - -**Use Cases:** -- Optional plugins (monitoring, logging) -- Analytics that can fail without breaking app -- Optional features - -### 4. ROLLBACK Strategy - -Trigger failure and cleanup on error. - -```typescript -timeoutManager.setRecoveryConfig('my-plugin', { - strategy: RecoveryStrategy.ROLLBACK, - maxRetries: 0 -}); - -// Behavior: -// → Hook fails -// → Signal for rollback -// → Previous state restored -// → Error thrown -``` - -**Use Cases:** -- Database migrations -- Configuration changes -- State-dependent operations - -## Error Handling Patterns - -### Pattern 1: Essential Plugin with Fast Fail - -```typescript -timeoutManager.setTimeoutConfig('auth-plugin', { - onLoad: 2000, - onActivate: 1000 -}); - -timeoutManager.setRecoveryConfig('auth-plugin', { - strategy: RecoveryStrategy.FAIL_FAST, - maxRetries: 0 -}); -``` - -### Pattern 2: Resilient Plugin with Retries - -```typescript -timeoutManager.setTimeoutConfig('cache-plugin', { - onLoad: 5000, - onActivate: 3000 -}); - -timeoutManager.setRecoveryConfig('cache-plugin', { - strategy: RecoveryStrategy.RETRY, - maxRetries: 3, - retryDelayMs: 200, - backoffMultiplier: 2 -}); -``` - -### Pattern 3: Optional Plugin with Graceful Degradation - -```typescript -timeoutManager.setTimeoutConfig('analytics-plugin', { - onLoad: 3000, - onActivate: 2000 -}); - -timeoutManager.setRecoveryConfig('analytics-plugin', { - strategy: RecoveryStrategy.GRACEFUL, - maxRetries: 1, - retryDelayMs: 100, - fallbackValue: null // OK if analytics unavailable -}); -``` - -## Execution History and Diagnostics - -### Monitor Plugin Health - -```typescript -const timeoutManager = new LifecycleTimeoutManager(); - -// Execute hooks with timeout management -await timeoutManager.executeWithTimeout( - 'my-plugin', - 'onActivate', - () => pluginInstance.onActivate(), - timeoutManager.getTimeoutConfig('my-plugin').onActivate -); - -// Get execution statistics -const stats = timeoutManager.getExecutionStats('my-plugin'); -console.log({ - totalAttempts: stats.totalAttempts, - successes: stats.successes, - failures: stats.failures, - timeouts: stats.timeouts, - averageDuration: `${stats.averageDuration.toFixed(2)}ms` -}); - -// Output: -// { -// totalAttempts: 5, -// successes: 4, -// failures: 1, -// timeouts: 0, -// averageDuration: "145.20ms" -// } -``` - -### Analyze Failure Patterns - -```typescript -const history = timeoutManager.getExecutionHistory('my-plugin'); - -history.forEach(context => { - console.log(`Hook: ${context.hook}`); - console.log(` Status: ${context.error ? 'FAILED' : 'SUCCESS'}`); - console.log(` Duration: ${context.duration}ms`); - console.log(` Retries: ${context.retryCount}/${context.maxRetries}`); - - if (context.error) { - console.log(` Error: ${context.error.message}`); - } -}); -``` - -### Track Timeout Events - -```typescript -const history = timeoutManager.getExecutionHistory('my-plugin'); - -const timeouts = history.filter(ctx => ctx.timedOut); -if (timeouts.length > 0) { - console.warn(`Plugin had ${timeouts.length} timeouts`); - console.warn(`Configured timeout: ${timeouts[0].configuredTimeout}ms`); -} -``` - -### Export Metrics - -```typescript -function getPluginMetrics(manager: LifecycleTimeoutManager, pluginId: string) { - const stats = manager.getExecutionStats(pluginId); - const successRate = stats.totalAttempts > 0 - ? (stats.successes / stats.totalAttempts * 100).toFixed(2) - : 'N/A'; - - return { - plugin_id: pluginId, - executions_total: stats.totalAttempts, - executions_success: stats.successes, - executions_failed: stats.failures, - executions_timeout: stats.timeouts, - success_rate_percent: successRate, - average_duration_ms: stats.averageDuration.toFixed(2) - }; -} -``` - -## Integration with PluginRegistry - -### Manual Integration Pattern - -```typescript -import { PluginRegistry, LifecycleTimeoutManager } from '@mindblock/middleware'; - -const registry = new PluginRegistry(); -const timeoutManager = new LifecycleTimeoutManager(); - -// Configure timeouts before loading plugins -timeoutManager.setTimeoutConfig('my-plugin', { onLoad: 3000 }); -timeoutManager.setRecoveryConfig('my-plugin', { - strategy: RecoveryStrategy.RETRY, - maxRetries: 2, - retryDelayMs: 100 -}); - -// When plugin lifecycle hooks are called, wrap with timeout: -const plugin = await registry.load('my-plugin'); - -try { - const result = await timeoutManager.executeWithTimeout( - plugin.metadata.id, - 'onInit', - () => plugin.plugin.onInit?.(config, context), - timeoutManager.getTimeoutConfig(plugin.metadata.id).onInit - ); -} catch (error) { - console.error(`Plugin initialization failed: ${error.message}`); -} -``` - -## Configuration Best Practices - -### 1. Environment-Based Timeouts - -```typescript -const isDevelopment = process.env.NODE_ENV === 'development'; - -timeoutManager.setTimeoutConfig('slow-plugin', { - onLoad: isDevelopment ? 10000 : 5000, // More generous in dev - onActivate: isDevelopment ? 5000 : 2000 -}); -``` - -### 2. Service-Level Configuration - -```typescript -// Database initialization plugin – longer timeout -timeoutManager.setTimeoutConfig('db-plugin', { - onLoad: 15000, // DB connections can be slow - onActivate: 10000 -}); - -// Cache plugin – shorter timeout -timeoutManager.setTimeoutConfig('cache-plugin', { - onLoad: 3000, // Should be fast - onActivate: 1000 -}); - -// Analytics plugin – don't block app -timeoutManager.setRecoveryConfig('analytics-plugin', { - strategy: RecoveryStrategy.GRACEFUL, - fallbackValue: null -}); -``` - -### 3. Monitoring and Alerting - -```typescript -setInterval(() => { - const plugins = ['auth-plugin', 'cache-plugin', 'analytics-plugin']; - - plugins.forEach(pluginId => { - const stats = timeoutManager.getExecutionStats(pluginId); - - if (stats.failures > 5) { - console.warn(`⚠️ Plugin ${pluginId} has ${stats.failures} failures`); - } - - if (stats.averageDuration > 2000) { - console.warn(`⚠️ Plugin ${pluginId} average duration: ${stats.averageDuration}ms`); - } - }); -}, 60000); // Check every minute -``` - -## Troubleshooting - -### Issue: Plugin Hangs During Load - -**Symptom:** Plugin appears to hang indefinitely - -**Diagnosis:** -```typescript -// Check timeout config -const config = timeoutManager.getTimeoutConfig('my-plugin'); -console.log('onLoad timeout:', config.onLoad); - -// Monitor execution -const history = timeoutManager.getExecutionHistory('my-plugin'); -console.log('Recent operations:', history.slice(-5)); -``` - -**Solution:** - -```typescript -// Increase timeout if plugin legitimately needs more time -timeoutManager.setTimeoutConfig('my-plugin', { - onLoad: 15000 // Increase from 5000 to 15 seconds -}); - -// Or enable retries -timeoutManager.setRecoveryConfig('my-plugin', { - strategy: RecoveryStrategy.RETRY, - maxRetries: 3, - retryDelayMs: 200 -}); -``` - -### Issue: Plugin Fails After Multiple Retries - -**Symptom:** Plugin keeps retrying but never succeeds - -**Diagnosis:** -```typescript -const history = timeoutManager.getExecutionHistory('my-plugin'); -const failures = history.filter(h => h.error); - -failures.forEach(f => { - console.log(`Failed: ${f.error?.message}`); - console.log(`Attempt ${f.retryCount}/${f.maxRetries}`); -}); -``` - -**Solution:** - -```typescript -// Switch to fail-fast if problem is not transient -timeoutManager.setRecoveryConfig('my-plugin', { - strategy: RecoveryStrategy.FAIL_FAST -}); - -// Or use graceful degradation if plugin is optional -timeoutManager.setRecoveryConfig('my-plugin', { - strategy: RecoveryStrategy.GRACEFUL, - fallbackValue: null -}); -``` - -### Issue: High Latency from Retries - -**Symptom:** Plugin operations slow due to retry delays - -**Diagnosis:** -```typescript -const stats = timeoutManager.getExecutionStats('my-plugin'); -console.log(`Average duration: ${stats.averageDuration}ms`); -console.log(`Failures: ${stats.failures}`); - -// Calculate expected delay -const baseDelay = 100; -const retries = 3; -const backoff = 2; -const expectedDelay = baseDelay * (Math.pow(backoff, retries) - 1); -console.log(`Expected retry delay: ${expectedDelay}ms`); -``` - -**Solution:** - -```typescript -// Reduce retry count for fast-fail plugins -timeoutManager.setRecoveryConfig('my-plugin', { - maxRetries: 1, // Reduce from 3 to 1 - retryDelayMs: 50 // Reduce delay -}); - -// Or remove retries entirely for non-transient errors -timeoutManager.setRecoveryConfig('my-plugin', { - strategy: RecoveryStrategy.FAIL_FAST -}); -``` - -## API Reference - -### LifecycleTimeoutManager - -```typescript -class LifecycleTimeoutManager { - // Configuration Methods - setTimeoutConfig(pluginId: string, config: LifecycleTimeoutConfig): void - getTimeoutConfig(pluginId: string): LifecycleTimeoutConfig - setRecoveryConfig(pluginId: string, config: RecoveryConfig): void - getRecoveryConfig(pluginId: string): RecoveryConfig - - // Execution Method - executeWithTimeout( - pluginId: string, - hookName: string, - hookFn: () => Promise, - timeoutMs?: number - ): Promise - - // Diagnostics Methods - getExecutionHistory(pluginId: string): LifecycleErrorContext[] - clearExecutionHistory(pluginId: string): void - getExecutionStats(pluginId: string): ExecutionStats - reset(): void -} -``` - -### RecoveryStrategy Enum - -```typescript -enum RecoveryStrategy { - RETRY = 'retry', // Automatic retry with backoff - FAIL_FAST = 'fail-fast', // Immediate error throw - GRACEFUL = 'graceful', // Continue with fallback value - ROLLBACK = 'rollback' // Trigger rollback -} -``` - -## Performance Impact - -**Typical Overhead:** -- Timeout checking: <1ms per operation -- Retry logic: Depends on configuration -- History tracking: <0.5ms per operation -- Overall: <2% impact on plugin loading - -**Memory Impact:** -- Per plugin: ~5KB for configurations -- Execution history: ~100 bytes per operation -- Total: <1MB for 100 plugins with 1000 operations each - -## Examples - -### Example 1: Production Configuration - -```typescript -const timeoutManager = new LifecycleTimeoutManager(); - -// Auth plugin – must succeed -timeoutManager.setTimeoutConfig('auth', { onLoad: 2000, onActivate: 1000 }); -timeoutManager.setRecoveryConfig('auth', { strategy: RecoveryStrategy.FAIL_FAST }); - -// Cache plugin – resilient -timeoutManager.setTimeoutConfig('cache', { onLoad: 5000, onActivate: 3000 }); -timeoutManager.setRecoveryConfig('cache', { - strategy: RecoveryStrategy.RETRY, - maxRetries: 2, - retryDelayMs: 100 -}); - -// Analytics – optional -timeoutManager.setTimeoutConfig('analytics', { onLoad: 3000 }); -timeoutManager.setRecoveryConfig('analytics', { - strategy: RecoveryStrategy.GRACEFUL, - fallbackValue: null -}); -``` - -### Example 2: Development Configuration - -```typescript -const timeoutManager = new LifecycleTimeoutManager(); - -// Generous timeouts for debugging -timeoutManager.setTimeoutConfig('slow-plugin', { - onLoad: 30000, // 30 seconds – plenty of time for breakpoints - onActivate: 20000 -}); - -// Retry failures in development -timeoutManager.setRecoveryConfig('slow-plugin', { - strategy: RecoveryStrategy.RETRY, - maxRetries: 5, - retryDelayMs: 500 -});

-if (!result.valid) { - console.error('Invalid config:', result.errors); -} -``` - -## Plugin Lifecycle - -``` -┌─────────────────────────────────────────────┐ -│ Plugin Lifecycle Flow │ -└─────────────────────────────────────────────┘ - - load() - │ - ▼ - onLoad() ──► Initialization validation - │ - ├────────────────┐ - │ │ - init() manual config - │ │ - ▼ ▼ - onInit() ◄─────────┘ - │ - ▼ - activate() - │ - ▼ - onActivate() ──► Plugin ready & active - │ - │ (optionally) - ├─► reload() ──► onReload() - │ - ▼ (eventually) - deactivate() - │ - ▼ - onDeactivate() - │ - ▼ - unload() - │ - ▼ - onUnload() - │ - ▼ - ✓ Removed -``` - -### Lifecycle Hooks - -| Hook | When Called | Purpose | -|------|-------------|---------| -| `onLoad` | After module import | Validate dependencies, setup | -| `onInit` | After configuration merge | Initialize with config | -| `onActivate` | When activated | Start services, open connections | -| `onDeactivate` | When deactivated | Stop services, cleanup | -| `onUnload` | Before removal | Final cleanup | -| `onReload` | On configuration change | Update configuration without unloading | - -## Error Handling - -### Error Types - -```typescript -// Plugin not found -try { - registry.getPluginOrThrow('unknown-plugin');

- } -} - -// Version mismatch -catch (error) { - if (error instanceof PluginVersionError) { - console.error('Version incompatible'); - } -} -``` - -## Examples - -### Example 1: Rate Limiting Plugin - -```typescript -export class RateLimitPlugin implements PluginInterface { - metadata: PluginMetadata = { - id: 'com.example.rate-limit', - name: 'Rate Limiting', - version: '1.0.0', - description: 'Rate limiting middleware' - }; - - private store = new Map(); - - getMiddleware() { - return (req: Request, res: Response, next: NextFunction) => { - const key = req.ip; - const now = Date.now(); - const windowMs = 60 * 1000; - - if (!this.store.has(key)) { - this.store.set(key, []); - } - - const timestamps = this.store.get(key)!; - const recentRequests = timestamps.filter(t => now - t < windowMs); - - if (recentRequests.length > 100) { - return res.status(429).json({ error: 'Too many requests' }); - } - - recentRequests.push(now); - this.store.set(key, recentRequests); - - next(); - }; - } -} -``` - -### Example 2: Logging Plugin with Configuration - -```typescript -export class LoggingPlugin implements PluginInterface { - metadata: PluginMetadata = { - id: 'com.example.logging', - name: 'Request Logging', - version: '1.0.0', - description: 'Log all HTTP requests', - configSchema: { - properties: { - logLevel: { type: 'string', enum: ['debug', 'info', 'warn', 'error'] }, - excludePaths: { type: 'array', items: { type: 'string' } } - } - } - }; - - private config: PluginConfig; - - validateConfig(config: PluginConfig) { - if (config.options?.logLevel && !['debug', 'info', 'warn', 'error'].includes(config.options.logLevel)) { - return { valid: false, errors: ['Invalid logLevel'] }; - } - return { valid: true, errors: [] }; - } - - async onInit(config: PluginConfig) { - this.config = config; - } - - getMiddleware() { - return (req: Request, res: Response, next: NextFunction) => { - const excludePaths = this.config.options?.excludePaths || []; - if (!excludePaths.includes(req.path)) { - console.log(`[${this.config.options?.logLevel || 'info'}] ${req.method} ${req.path}`); - } - next(); - }; - } -} -``` - -## Best Practices - -### 1. Plugin Naming Convention - -- Use scoped package names: `@organization/plugin-feature` -- Use descriptive plugin IDs: `com.organization.plugin.feature` -- Include "plugin" in package and plugin names - -### 2. Version Management - -- Follow semantic versioning (semver) for your plugin -- Specify middleware version requirements in package.json -- Test against multiple middleware versions - -### 3. Configuration Validation - -```typescript -validateConfig(config: PluginConfig) { - const errors: string[] = []; - const warnings: string[] = []; - - if (!config.options?.require Field) { - errors.push('requiredField is required'); - } - - if (config.options?.someValue > 1000) { - warnings.push('someValue is unusually high'); - } - - return { valid: errors.length === 0, errors, warnings }; -} -``` - -### 4. Error Handling - -```typescript -async onInit(config: PluginConfig, context: PluginContext) { - try { - // Initialization logic - } catch (error) { - context.logger?.error(`Failed to initialize: ${error.message}`); - throw error; // Let framework handle it - } -} -``` - -### 5. Resource Cleanup - -```typescript -private connections: any[] = []; - -async onActivate(context: PluginContext) { - // Open resources - this.connections.push(await openConnection()); -} - -async onDeactivate(context: PluginContext) { - // Close resources - for (const conn of this.connections) { - await conn.close(); - } - this.connections = []; -} -``` - -### 6. Dependencies - -```typescript -getDependencies(): string[] { - return [ - 'com.example.auth-plugin', // This plugin must load first - 'com.example.logging-plugin' - ]; -} -``` - -### 7. Documentation - -- Write clear README for your plugin -- Include configuration examples -- Document any external dependencies -- Provide troubleshooting guide -- Include integration examples - -### 8. Testing - -```typescript -describe('MyPlugin', () => { - let plugin: MyPlugin; - - beforeEach(() => { - plugin = new MyPlugin(); - }); - - it('should validate configuration', () => { - const result = plugin.validateConfig({ enabled: true }); - expect(result.valid).toBe(true); - }); - - it('should handle middleware requests', () => { - const middleware = plugin.getMiddleware(); - const req = {}, res = { setHeader: jest.fn() }, next = jest.fn(); - middleware(req as any, res as any, next); - expect(next).toHaveBeenCalled(); - }); -}); -``` - -## Advanced Topics - -### Priority-Based Execution - -Set plugin priority to control execution order: - -```typescript -metadata = { - // ... - priority: 10 // Higher = executes later -}; -``` - -### Plugin Communication - -Plugins can access other loaded plugins: - -```typescript -async getOtherPlugin(context: PluginContext) { - const otherPlugin = context.plugins?.get('com.example.other-plugin'); - const exports = otherPlugin?.instance.getExports?.(); - return exports; -} -``` - -### Runtime Configuration Updates - -Update plugin configuration without full reload: - -```typescript -await registry.reload(pluginId, { - enabled: true, - options: { /* new config */ } -}); -``` - -## Troubleshooting - -### Plugin Not Loading - -1. Check that npm package is installed: `npm list @yourorg/plugin-name` -2. Verify `main` field in plugin's package.json -3. Check that plugin exports a valid PluginInterface -4. Review logs for specific error messages - -### Configuration Errors - -1. Validate config against schema -2. Check required fields are present -3. Ensure all options match expected types - -### Permission Issues - -1. Check plugin version compatibility -2. Verify all dependencies are met -3. Check that required plugins are loaded first - ---- - -For more examples and details, see the [example plugin template](../src/plugins/example.plugin.ts). diff --git a/middleware/docs/PLUGIN_QUICKSTART.md b/middleware/docs/PLUGIN_QUICKSTART.md deleted file mode 100644 index c5cde301..00000000 --- a/middleware/docs/PLUGIN_QUICKSTART.md +++ /dev/null @@ -1,480 +0,0 @@ -# Plugin Development Quick Start Guide - -This guide walks you through creating your first middleware plugin for `@mindblock/middleware`. - -## 5-Minute Setup - -### 1.

Plugin Naming Convention + +- Use scoped package names: `@organization/plugin-feature` +- Use descriptive plugin IDs: `com.organization.plugin.feature` +- Include "plugin" in package and plugin names + +### 2. Version Management + +- Follow semantic versioning (semver) for your plugin +- Specify middleware version requirements in package.json +- Test against multiple middleware versions + +### 3. Configuration Validation + +```typescript +validateConfig(config: PluginConfig) { + const errors: string[] = []; + const warnings: string[] = []; + + if (!config.options?.require Field) { + errors.push('requiredField is required'); + } + + if (config.options?.someValue > 1000) { + warnings.push('someValue is unusually high'); + } + + return { valid: errors.length === 0, errors, warnings }; +} +``` + +### 4. Error Handling + +```typescript +async onInit(config: PluginConfig, context: PluginContext) { + try { + // Initialization logic + } catch (error) { + context.logger?.error(`Failed to initialize: ${error.message}`); + throw error; // Let framework handle it + } +} +``` + +### 5. Resource Cleanup + +```typescript +private connections: any[] = []; + +async onActivate(context: PluginContext) { + // Open resources + this.connections.push(await openConnection()); +} + +async onDeactivate(context: PluginContext) { + // Close resources + for (const conn of this.connections) { + await conn.close(); + } + this.connections = []; +} +``` + +### 6. Dependencies + +```typescript +getDependencies(): string[] { + return [ + 'com.example.auth-plugin', // This plugin must load first + 'com.example.logging-plugin' + ]; +} +``` + +### 7. Documentation + +- Write clear README for your plugin +- Include configuration examples +- Document any external dependencies +- Provide troubleshooting guide +- Include integration examples + +### 8. Testing + +```typescript +describe('MyPlugin', () => { + let plugin: MyPlugin; + + beforeEach(() => { + plugin = new MyPlugin(); + }); + + it('should validate configuration', () => { + const result = plugin.validateConfig({ enabled: true }); + expect(result.valid).toBe(true); + }); + + it('should handle middleware requests', () => { + const middleware = plugin.getMiddleware(); + const req = {}, res = { setHeader: jest.fn() }, next = jest.fn(); + middleware(req as any, res as any, next); + expect(next).toHaveBeenCalled(); + }); +}); +``` + +## Advanced Topics + +### Priority-Based Execution + +Set plugin priority to control execution order: + +```typescript +metadata = { + // ... + priority: 10 // Higher = executes later +}; +``` + +### Plugin Communication + +Plugins can access other loaded plugins: + +```typescript +async getOtherPlugin(context: PluginContext) { + const otherPlugin = context.plugins?.get('com.example.other-plugin'); + const exports = otherPlugin?.instance.getExports?.(); + return exports; +} +``` + +### Runtime Configuration Updates + +Update plugin configuration without full reload: + +```typescript +await registry.reload(pluginId, { + enabled: true, + options: { /* new config */ } +}); +``` + +## Troubleshooting + +### Plugin Not Loading + +1. Check that npm package is installed: `npm list @yourorg/plugin-name` +2. Verify `main` field in plugin's package.json +3. Check that plugin exports a valid PluginInterface +4. Review logs for specific error messages + +### Configuration Errors + +1. Validate config against schema +2. Check required fields are present +3. Ensure all options match expected types + +### Permission Issues + +1. Check plugin version compatibility +2. Verify all dependencies are met +3. Check that required plugins are loaded first + +--- + +For more examples and details, see the [example plugin template](../src/plugins/example.plugin.ts). diff --git a/middleware/docs/PLUGIN_QUICKSTART.md b/middleware/docs/PLUGIN_QUICKSTART.md new file mode 100644 index 00000000..c5cde301 --- /dev/null +++ b/middleware/docs/PLUGIN_QUICKSTART.md @@ -0,0 +1,480 @@ +# Plugin Development Quick Start Guide + +This guide walks you through creating your first middleware plugin for `@mindblock/middleware`. + +## 5-Minute Setup + +### 1.

Plugin Naming Convention + +- Use scoped package names: `@organization/plugin-feature` +- Use descriptive plugin IDs: `com.organization.plugin.feature` +- Include "plugin" in package and plugin names + +### 2. Version Management + +- Follow semantic versioning (semver) for your plugin +- Specify middleware version requirements in package.json +- Test against multiple middleware versions + +### 3. Configuration Validation + +```typescript +validateConfig(config: PluginConfig) { + const errors: string[] = []; + const warnings: string[] = []; + + if (!config.options?.require Field) { + errors.push('requiredField is required'); + } + + if (config.options?.someValue > 1000) { + warnings.push('someValue is unusually high'); + } + + return { valid: errors.length === 0, errors, warnings }; +} +``` + +### 4. Error Handling + +```typescript +async onInit(config: PluginConfig, context: PluginContext) { + try { + // Initialization logic + } catch (error) { + context.logger?.error(`Failed to initialize: ${error.message}`); + throw error; // Let framework handle it + } +} +``` + +### 5. Resource Cleanup + +```typescript +private connections: any[] = []; + +async onActivate(context: PluginContext) { + // Open resources + this.connections.push(await openConnection()); +} + +async onDeactivate(context: PluginContext) { + // Close resources + for (const conn of this.connections) { + await conn.close(); + } + this.connections = []; +} +``` + +### 6. Dependencies + +```typescript +getDependencies(): string[] { + return [ + 'com.example.auth-plugin', // This plugin must load first + 'com.example.logging-plugin' + ]; +} +``` + +### 7. Documentation + +- Write clear README for your plugin +- Include configuration examples +- Document any external dependencies +- Provide troubleshooting guide +- Include integration examples + +### 8. Testing + +```typescript +describe('MyPlugin', () => { + let plugin: MyPlugin; + + beforeEach(() => { + plugin = new MyPlugin(); + }); + + it('should validate configuration', () => { + const result = plugin.validateConfig({ enabled: true }); + expect(result.valid).toBe(true); + }); + + it('should handle middleware requests', () => { + const middleware = plugin.getMiddleware(); + const req = {}, res = { setHeader: jest.fn() }, next = jest.fn(); + middleware(req as any, res as any, next); + expect(next).toHaveBeenCalled(); + }); +}); +``` + +## Advanced Topics + +### Priority-Based Execution + +Set plugin priority to control execution order: + +```typescript +metadata = { + // ... + priority: 10 // Higher = executes later +}; +``` + +### Plugin Communication + +Plugins can access other loaded plugins: + +```typescript +async getOtherPlugin(context: PluginContext) { + const otherPlugin = context.plugins?.get('com.example.other-plugin'); + const exports = otherPlugin?.instance.getExports?.(); + return exports; +} +``` + +### Runtime Configuration Updates + +Update plugin configuration without full reload: + +```typescript +await registry.reload(pluginId, { + enabled: true, + options: { /* new config */ } +}); +``` + +## Troubleshooting + +### Plugin Not Loading + +1.

- if (!excludePaths.includes(req.path)) { - console.log(`[${this.config.options?.logLevel || 'info'}] ${req.method} ${req.path}`); - } - next(); - }; - } -} -``` - -## Best Practices - -### 1. Plugin Naming Convention - -- Use scoped package names: `@organization/plugin-feature` -- Use descriptive plugin IDs: `com.organization.plugin.feature` -- Include "plugin" in package and plugin names - -### 2. Version Management - -- Follow semantic versioning (semver) for your plugin -- Specify middleware version requirements in package.json -- Test against multiple middleware versions - -### 3. Configuration Validation - -```typescript -validateConfig(config: PluginConfig) { - const errors: string[] = []; - const warnings: string[] = []; - - if (!config.options?.require Field) { - errors.push('requiredField is required'); - } - - if (config.options?.someValue > 1000) { - warnings.push('someValue is unusually high'); - } - - return { valid: errors.length === 0, errors, warnings }; -} -``` - -### 4. Error Handling - -```typescript -async onInit(config: PluginConfig, context: PluginContext) { - try { - // Initialization logic - } catch (error) { - context.logger?.error(`Failed to initialize: ${error.message}`); - throw error; // Let framework handle it - } -} -``` - -### 5. Resource Cleanup - -```typescript -private connections: any[] = []; - -async onActivate(context: PluginContext) { - // Open resources - this.connections.push(await openConnection()); -} - -async onDeactivate(context: PluginContext) { - // Close resources - for (const conn of this.connections) { - await conn.close(); - } - this.connections = []; -} -``` - -### 6. Dependencies - -```typescript -getDependencies(): string[] { - return [ - 'com.example.auth-plugin', // This plugin must load first - 'com.example.logging-plugin' - ]; -} -``` - -### 7. Documentation - -- Write clear README for your plugin -- Include configuration examples -- Document any external dependencies -- Provide troubleshooting guide -- Include integration examples - -### 8. Testing - -```typescript -describe('MyPlugin', () => { - let plugin: MyPlugin; - - beforeEach(() => { - plugin = new MyPlugin(); - }); - - it('should validate configuration', () => { - const result = plugin.validateConfig({ enabled: true }); - expect(result.valid).toBe(true); - }); - - it('should handle middleware requests', () => { - const middleware = plugin.getMiddleware(); - const req = {}, res = { setHeader: jest.fn() }, next = jest.fn(); - middleware(req as any, res as any, next); - expect(next).toHaveBeenCalled(); - }); -}); -``` - -## Advanced Topics - -### Priority-Based Execution - -Set plugin priority to control execution order: - -```typescript -metadata = { - // ... - priority: 10 // Higher = executes later -}; -``` - -### Plugin Communication - -Plugins can access other loaded plugins: - -```typescript -async getOtherPlugin(context: PluginContext) { - const otherPlugin = context.plugins?.get('com.example.other-plugin'); - const exports = otherPlugin?.instance.getExports?.(); - return exports; -} -``` - -### Runtime Configuration Updates - -Update plugin configuration without full reload: - -```typescript -await registry.reload(pluginId, { - enabled: true, - options: { /* new config */ } -}); -``` - -## Troubleshooting - -### Plugin Not Loading - -1. Check that npm package is installed: `npm list @yourorg/plugin-name` -2. Verify `main` field in plugin's package.json -3. Check that plugin exports a valid PluginInterface -4. Review logs for specific error messages - -### Configuration Errors - -1. Validate config against schema -2. Check required fields are present -3. Ensure all options match expected types - -### Permission Issues - -1. Check plugin version compatibility -2. Verify all dependencies are met -3.

practices for the MindBlock middleware package. + +## Table of Contents + +- [Test Tiers](#test-tiers) +- [Running Tests](#running-tests) +- [Test Utilities](#test-utilities) +- [Writing Tests](#writing-tests) +- [Best Practices](#best-practices) + +## Test Tiers + +We use three tiers of testing to ensure comprehensive coverage at different levels: + +### Unit Tests (`tests/unit/`) + +**Purpose**: Test individual components in isolation + +**Configuration**: `jest.unit.config.ts` + +**Coverage Thresholds**: +- Branches: 80% +- Functions: 80% +- Lines: 80% +- Statements: 80% + +**When to use**: +- Testing pure functions +- Testing class methods with mocked dependencies +- Testing middleware logic without full NestJS app + +**Example**: +```typescript +import { PluginManager } from '../../../src/common/plugin.manager'; + +describe('PluginManager', () => { + it('should register a plugin successfully', () => { + const manager = new PluginManager(); + expect(manager.hasPlugin('TestPlugin')).toBe(false); + }); +}); +``` + +### Integration Tests (`tests/integration/`) + +**Purpose**: Test interactions between multiple components + +**Configuration**: `jest.integration.config.ts` + +**Coverage Thresholds**: +- Branches: 70% +- Functions: 70% +- Lines: 70% +- Statements: 70% + +**Timeout**: 10 seconds + +**When to use**: +- Testing middleware chains +- Testing services with their dependencies +- Testing plugin lifecycle with PluginManager + +**Example**: +```typescript +import { createTestApp } from '../utils/create-test-app'; +import { MetricsMiddleware } from '../../src/monitoring/metrics.middleware'; + +describe('MetricsMiddleware Integration', () => { + it('should track requests across middleware chain', async () => { + const app = await createTestApp({ + middlewares: [MetricsMiddleware], + }); + + await app.init(); + // ... test integration + await app.close(); + }); +}); +``` + +### E2E Tests (`tests/e2e/`) + +**Purpose**: Test complete application flows + +**Configuration**: `jest.e2e.config.ts` + +**Coverage Thresholds**: +- Branches: 60% +- Functions: 60% +- Lines: 60% +- Statements: 60% + +**Timeout**: 30 seconds + +**When to use**: +- Testing full HTTP request/response cycles +- Testing multiple middleware working together +- Testing real-world scenarios + +**Example**: +```typescript +import { createTestApp, createTestRequest } from '../utils'; +import { PrometheusMetricsPlugin } from '../../src/monitoring/prometheus.plugin'; + +describe('Prometheus Metrics E2E', () => { + it('should expose /metrics

app.init(); + const request = createTestRequest(app); + + await request.get('/metrics') + .expect(200) + .expect('Content-Type', /text\/plain/); + + await app.close(); + }); +}); +``` + +## Running Tests + +### Run all tests +```bash +npm test +``` + +### Run specific test tier +```bash +npm run test:unit # Unit tests only +npm run test:integration # Integration tests only +npm run test:e2e # E2E tests only +``` + +### Run with coverage +```bash +npm run test:cov # All tests with coverage +npm run test:unit:cov # Unit tests with coverage +npm run test:integration:cov # Integration tests with coverage +npm run test:e2e:cov # E2E tests with coverage +``` + +### Watch mode +```bash +npm run test:watch +``` + +## Test Utilities + +### Mock Factories + +Located in `tests/utils/mock-express.ts` + +#### `mockRequest(overrides?)` +Create a typed mock Express request object. + +```typescript +import { mockRequest } from '../utils'; + +const req = mockRequest({ + method: 'POST', + path: '/api/users', + body: { name: 'John' }, +}); +``` + +#### `mockResponse(overrides?)` +Create a typed mock Express response object. + +```typescript +import { mockResponse } from '../utils'; + +const res = mockResponse(); +res.status.mockReturnValue(res); // Chainable + +// Check if status was called +expect(res.status).toHaveBeenCalledWith(200); +``` + +#### `mockNext()` +Create a typed mock next function. + +```typescript +import { mockNext } from '../utils'; + +const next = mockNext(); +middleware(req, res, next); +expect(next).toHaveBeenCalled(); +``` + +#### `createMiddlewareTestContext(overrides?)` +Create complete test context for middleware testing. + +```typescript +import { createMiddlewareTestContext } from '../utils'; + +const { req, res, next } = createMiddlewareTestContext({ + req: { method: 'POST' }, + res: { statusCode: 201 }, +}); +``` + +### Test App Factory + +Located in `tests/utils/create-test-app.ts` + +#### `createTestApp(options)` +Create a minimal NestJS test application. + +```typescript +import { createTestApp } from '../utils'; + +const app = await createTestApp({ + middlewares: [SomeMiddleware], + providers: [SomeService], + controllers: [SomeController], +}); + +await app.init(); +// ... run tests +await app.close(); +``` + +#### `createMockExecutionContext(handler?, type?)` +Create a mock execution context for testing guards/interceptors. + +```typescript +import { createMockExecutionContext } from '../utils'; + +const context = createMockExecutionContext(null, 'http'); +guard.canActivate(context); +``` + +#### `createTestRequest(app)` +Create a supertest wrapper for testing HTTP endpoints. + +```typescript +import { createTestApp, createTestRequest } from '../utils'; + +const app = await createTestApp({ controllers: [MyController] }); +await app.init(); + +const request = createTestRequest(app); +await request.get('/users').expect(200); + +await app.close(); +``` + +## Writing Tests + +### File Naming Conventions + +- Unit tests: `*.test.ts` or `*.spec.ts` in `tests/unit/` +- Integration tests: `*.test.ts` or `*.spec.ts` in `tests/integration/` +- E2E tests: `*.test.ts` or `*.spec.ts` in `tests/e2e/` + +### Test Structure + +```typescript +describe('ComponentName', () => { + let component: ComponentName; + + beforeEach(() => { + component = new ComponentName(); + }); + + describe('methodName', () => { + it('should do something', async () => { + // Arrange + const input = 'test'; + + // Act + const result = await component.methodName(input); + + // Assert + expect(result).toBe('expected'); + }); + + it('should handle edge case', async () => { + // Test edge cases + }); + }); +}); +``` + +## Best Practices + +### 1. Use Typed Mocks +Always use our typed mock factories instead of plain objects: + +```typescript +// ✅ Good +const { req, res, next } = createMiddlewareTestContext(); + +// ❌ Bad +const req = { method: 'GET' }; +``` + +### 2. Test Edge Cases +Don't just test the happy path: + +```typescript +it('should handle empty input', () => {}); +it('should handle null values', () => {}); +it('should handle malformed data', () => {}); +``` + +### 3. Keep Tests Isolated +Each test should be independent: + +```typescript +beforeEach(() => { + // Reset state +}); + +afterEach(async () => { + // Cleanup +}); +``` + +### 4. Use Descriptive Test Names +Test names should describe behavior: + +```typescript +// ✅ Good +it('should reject duplicate plugin registration', () => {}); + +// ❌ Bad +it('test duplicate', () => {}); +``` + +### 5. Test Async Code Properly +Always await promises and handle errors: + +```typescript +it('should throw on invalid input', async () => { + await expect(component.invalidMethod()).rejects.toThrow('Error message'); +}); +``` + +### 6. Mock External Dependencies +Isolate the unit under test: + +```typescript +const mockService = { + getData: jest.fn().mockResolvedValue({ id: 1 }), +}; +``` + +### 7. Clean Up Resources +Always close apps and clear mocks: + +```typescript +afterEach(async () => { + await app.close(); + jest.clearAllMocks(); +}); +``` + +## Debugging Tests + +### Run single test file +```bash +npx jest tests/unit/specific.test.ts +``` + +### Run test by pattern +```bash +npx jest -t "should register plugin" +``` + +### Debug with verbose output +```bash +npx jest --verbose +``` + +### Watch specific file +```bash +npx jest --watch tests/unit/specific.test.ts +``` + +## Coverage Reports + +View HTML coverage report: +```bash +npm run test:unit:cov +open coverage/unit/index.html +``` + +## Troubleshooting + +### Tests running slow +- Check if you're properly closing apps in `afterEach` +- Reduce timeouts in integration/E2E tests if possible +- Mock heavy external dependencies + +### Type errors in tests +- Ensure you're using typed mock factories +- Import types from correct locations +- Check that devDependencies are installed + +### Coverage not meeting thresholds +- Run coverage report to see uncovered lines +- Add tests for edge cases +- Test error handling paths diff --git a/middleware/tests/utils/create-test-app.ts b/middleware/tests/utils/create-test-app.ts new file mode 100644 index 00000000..291a3c83 --- /dev/null +++ b/middleware/tests/utils/create-test-app.ts @@ -0,0 +1,156 @@ +import { INestApplication, ExecutionContext } from '@nestjs/common';
