When a module registers configuration with `env` tags, the framework searches for environment variables in the following priority order: + +1. `MODULENAME_ENV_VAR` (module name prefix - highest priority) +2. `ENV_VAR_MODULENAME` (module name suffix - medium priority) +3. `ENV_VAR` (original variable name - lowest priority) + +This allows different modules to use the same configuration field names without conflicts. + +#### Example + +Consider a reverse proxy module with this configuration: + +```go +type ReverseProxyConfig struct { + DefaultBackend string `env:"DEFAULT_BACKEND"` + RequestTimeout int `env:"REQUEST_TIMEOUT"` +} +``` + +The framework will search for environment variables in this order: + +```bash +# For the reverseproxy module's DEFAULT_BACKEND field: +REVERSEPROXY_DEFAULT_BACKEND=http://api.example.com # Highest priority +DEFAULT_BACKEND_REVERSEPROXY=http://alt.example.com # Medium priority +DEFAULT_BACKEND=http://fallback.example.com # Lowest priority +``` + +If `REVERSEPROXY_DEFAULT_BACKEND` is set, it will be used.

For example: + +- Module name `"reverseproxy"` โ†’ Environment prefix `REVERSEPROXY_` +- Module name `"httpserver"` โ†’ Environment prefix `HTTPSERVER_` +- Module name `"database"` โ†’ Environment prefix `DATABASE_` + ### Instance-Aware Configuration Instance-aware configuration is a powerful feature that allows you to manage multiple instances of the same configuration type using environment variables with instance-specific prefixes. This is particularly useful for scenarios like multiple database connections, cache instances, or service endpoints where each instance needs separate configuration. diff --git a/LICENSE b/LICENSE index eefd316b..93cb6773 100644 --- a/LICENSE +++ b/LICENSE @@ -1,6 +1,6 @@ MIT License -Copyright (c) 2025 GoCodeAlone +Copyright (c) 2025 CrisisTextLine Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal diff --git a/MIGRATION_GUIDE.md b/MIGRATION_GUIDE.md new file mode 100644 index 00000000..872a2c46 --- /dev/null +++ b/MIGRATION_GUIDE.md @@ -0,0 +1,289 @@ +# Migration Guide: From Standard API to Builder Pattern + +This guide helps you migrate from the traditional Modular framework API to the new decorator pattern and builder API introduced in v2.0. + +## Overview of Changes + +The framework has been enhanced with a new builder pattern that provides: + +1. **Decorator Pattern**: Composable application decorators for cross-cutting concerns +2. **Functional Options**: Clean builder API using functional options +3. **Enhanced Observer Pattern**: Integrated CloudEvents-based event system +4. **Tenant-Aware Applications**: Built-in multi-tenancy support +5. **Configuration Decorators**: Chainable configuration enhancement + +## Quick Migration Examples + +### Basic Application + +**Before (v1.x)**: +```go +cfg := &AppConfig{} +configProvider := modular.NewStdConfigProvider(cfg) +app := modular.NewStdApplication(configProvider, logger) +app.RegisterModule(&DatabaseModule{}) +app.RegisterModule(&APIModule{}) +app.Run() +``` + +**After (v2.x)**: +```go +app, err := modular.NewApplication( + modular.WithLogger(logger), + modular.WithConfigProvider(modular.NewStdConfigProvider(&AppConfig{})), + modular.WithModules( + &DatabaseModule{}, + &APIModule{}, + ), +) +if err != nil { + logger.Error("Failed to create application", "error", err) + os.Exit(1) +} +app.Run() +``` + +### Multi-Tenant Application + +**Before (v1.x)**: +```go +// Required manual setup of tenant service and configuration +tenantService := modular.NewStandardTenantService(logger) +app.RegisterService("tenantService", tenantService) +// Manual tenant registration and configuration... +``` + +**After (v2.x)**: +```go +tenantLoader := &MyTenantLoader{} +app, err := modular.NewApplication( + modular.WithLogger(logger), + modular.WithConfigProvider(configProvider), + modular.WithTenantAware(tenantLoader), + modular.WithConfigDecorators( + modular.InstanceAwareConfig(), + modular.TenantAwareConfigDecorator(tenantLoader), + ), + modular.WithModules(modules...), +) +``` + +### Observable Application + +**Before (v1.x)**: +```go +// Required manual setup of ObservableApplication +app := modular.NewObservableApplication(configProvider, logger) +// Manual observer registration... +``` + +**After (v2.x)**: +```go +app, err := modular.NewApplication( + modular.WithLogger(logger), + modular.WithConfigProvider(configProvider), + modular.WithObserver(myObserverFunc), + modular.WithModules(modules...), +) +``` + +## Detailed Migration Steps + +### Step 1: Update Application Creation + +Replace `NewStdApplication` calls with the new `NewApplication` builder: + +1. **Identify**: Find all `modular.NewStdApplication()` calls +2. **Replace**: Convert to `modular.NewApplication()` with options +3. **Move modules**: Convert `app.RegisterModule()` calls to `modular.WithModules()` + +### Step 2: Handle Error Returns + +The new builder API returns an error, so handle it appropriately: + +```go +// Old: No error handling needed +app := modular.NewStdApplication(configProvider, logger) + +// New: Handle potential errors +app, err := modular.NewApplication( + modular.WithLogger(logger), + modular.WithConfigProvider(configProvider), +) +if err != nil { + // Handle error appropriately +} +``` + +### Step 3: Migrate Multi-Tenant Applications + +If you were using tenant functionality: + +1. **Create TenantLoader**: Implement the `TenantLoader` interface +2. **Add tenant option**: Use `WithTenantAware(loader)` +3. **Add config decorators**: Use `WithConfigDecorators()` for tenant-aware configuration + +### Step 4: Add Observer Functionality + +For applications that need event handling: + +```go +func myEventObserver(ctx context.Context, event cloudevents.Event) error { + log.Printf("Received event: %s from %s", event.Type(), event.Source()) + return nil +} + +app, err := modular.NewApplication( + // ... other options + modular.WithObserver(myEventObserver), +) +``` + +## New Functional Options + +### Core Options + +- `WithLogger(logger)` -

Reverse Proxy Example + +This example demonstrates a comprehensive health-aware reverse proxy setup using the modular framework. It showcases advanced health checking, circuit breaker patterns, and how to expose health endpoints for internal service monitoring. + +## Features Demonstrated + +### Health Checking +- **Comprehensive Backend Monitoring**: Health checks for all configured backends +- **Configurable Check Intervals**: Different health check intervals per backend +- **Smart Scheduling**: Skips health checks if recent requests have occurred +- **DNS Resolution Monitoring**: Tracks DNS resolution status for each backend +- **HTTP Connectivity Testing**: Tests actual HTTP connectivity with configurable timeouts +- **Custom Health Endpoints**: Support for custom health check endpoints per backend + +### Circuit Breaker Integration +- **Automatic Failure Detection**: Circuit breakers automatically detect failing backends +- **Per-Backend Configuration**: Different circuit breaker settings per backend +- **Health Status Integration**: Circuit breaker status is included in health reports +- **Configurable Thresholds**: Customizable failure thresholds and recovery timeouts + +### Health Endpoints +- **Overall Service Health**: `/health` endpoint that reflects overall service status +- **Detailed Backend Health**: `/metrics/reverseproxy/health` endpoint with detailed backend information +- **Proper HTTP Status Codes**: Returns 200 for healthy, 503 for unhealthy services +- **JSON Response Format**: Structured JSON responses with comprehensive status information + +## Backend Services + +The example starts several mock backend services to demonstrate different scenarios: + +### 1. Healthy API (port 9001) +- **Status**: Always healthy and responsive +- **Health Check**: `/health` endpoint always returns 200 +- **Circuit Breaker**: Configured with standard settings +- **Use Case**: Represents a reliable, well-functioning service + +### 2. Intermittent API (port 9002) +- **Status**: Fails every 3rd request (simulates intermittent issues) +- **Health Check**: Health endpoint is always available +- **Circuit Breaker**: More sensitive settings (2 failures trigger circuit open) +- **Use Case**: Represents a service with reliability issues + +### 3. Slow API (port 9003) +- **Status**: Always successful but with 2-second delay +- **Health Check**: Health endpoint responds without delay +- **Circuit Breaker**: Less sensitive settings (5 failures trigger circuit open) +- **Use Case**: Represents a slow but reliable service + +### 4. Unreachable API (port 9999) +- **Status**: Service is not started (connection refused) +- **Health Check**: Will fail DNS/connectivity tests +- **Circuit Breaker**: Very sensitive settings (1 failure triggers circuit open) +- **Use Case**: Represents an unreachable or down service + +## Configuration Features + +### Health Check Configuration +```yaml +health_check: + enabled: true + interval: "10s" # Global check interval + timeout: "3s" # Global timeout + recent_request_threshold: "30s" # Skip checks if recent traffic + expected_status_codes: [200, 204] # Expected healthy status codes + + # Per-backend overrides + backend_health_check_config: + healthy-api: + interval: "5s" # More frequent checks + timeout: "2s" +``` + +### Circuit Breaker Configuration +```yaml +circuit_breaker_config: + enabled: true + failure_threshold: 3 # Global failure threshold + open_timeout: "30s" # Global recovery timeout + +# Per-backend overrides +backend_circuit_breakers: + intermittent-api: + failure_threshold: 2 # More sensitive + open_timeout: "15s" # Faster recovery +``` + +## Running the Example + +1. **Start the application**: + ```bash + cd examples/health-aware-reverse-proxy + go run main.go + ``` + +2. **Test the backends**: + ```bash + # Test healthy API + curl http://localhost:8080/api/healthy + + # Test intermittent API (may fail on every 3rd request) + curl http://localhost:8080/api/intermittent + + # Test slow API (will take 2+ seconds) + curl http://localhost:8080/api/slow + + # Test unreachable API (will fail immediately) + curl http://localhost:8080/api/unreachable + ``` + +3. **Check overall service health**: + ```bash + # Overall health status (suitable for load balancer health checks) + curl http://localhost:8080/health + + # Detailed health information + curl http://localhost:8080/metrics/reverseproxy/health + ``` + +## Health Response Format + +### Overall Health Endpoint (`/health`) +```json +{ + "healthy": true, + "total_backends": 4, + "healthy_backends": 3, + "unhealthy_backends": 1, + "circuit_open_count": 1, + "last_check": "2024-01-01T12:00:00Z" +} +``` + +### Detailed Health Endpoint (`/metrics/reverseproxy/health`) +```json +{ + "healthy": true, + "total_backends": 4, + "healthy_backends": 3, + "unhealthy_backends": 1, + "circuit_open_count": 1, + "last_check": "2024-01-01T12:00:00Z", + "backend_details": { + "healthy-api": { + "backend_id": "healthy-api", + "url": "http://localhost:9001", + "healthy": true, + "last_check": "2024-01-01T12:00:00Z", + "last_success": "2024-01-01T12:00:00Z", + "response_time": "15ms", + "dns_resolved": true, + "resolved_ips": ["127.0.0.1"], + "circuit_breaker_open": false, + "circuit_breaker_state": "closed", + "circuit_failure_count": 0 + } + } +} +``` + +## Use Cases + +### 1.

+ +[![Go Reference](https://pkg.go.dev/badge/github.com/GoCodeAlone/modular/modules/eventlogger.svg)](https://pkg.go.dev/github.com/GoCodeAlone/modular/modules/eventlogger) + +The EventLogger Module provides structured logging capabilities for Observer pattern events in Modular applications. It acts as an Observer that can be registered with any Subject to log events to various output targets including console, files, and syslog. + +## Features + +- **Multiple Output Targets**: Support for console, file, and syslog outputs +- **Configurable Log Levels**: DEBUG, INFO, WARN, ERROR with per-target configuration +- **Multiple Output Formats**: Text, JSON, and structured formats +- **Event Type Filtering**: Log only specific event types +- **Async Processing**: Non-blocking event processing with buffering +- **Log Rotation**: Automatic file rotation for file outputs +- **Error Handling**: Graceful handling of output target failures +- **Observer Pattern Integration**: Seamless integration with ObservableApplication + +## Installation + +```go +import ( + "github.com/GoCodeAlone/modular" + "github.com/GoCodeAlone/modular/modules/eventlogger" +) + +// Register the eventlogger module with your Modular application +app.RegisterModule(eventlogger.NewModule()) +``` + +## Configuration + +The eventlogger module can be configured using the following options: + +```yaml +eventlogger: + enabled: true # Enable/disable event logging + logLevel: INFO # Minimum log level (DEBUG, INFO, WARN, ERROR) + format: structured # Default output format (text, json, structured) + bufferSize: 100 # Event buffer size for async processing + flushInterval: 5s # How often to flush buffered events + includeMetadata: true # Include event metadata in logs + includeStackTrace: false # Include stack traces for error events + eventTypeFilters: # Optional: Only log specific event types + - module.registered + - service.registered + - application.started + outputTargets: + - type: console # Console output + level: INFO + format: structured + console: + useColor: true + timestamps: true + - type: file # File output with rotation + level: DEBUG + format: json + file: + path: /var/log/modular-events.log + maxSize: 100 # MB + maxBackups: 5 + maxAge: 30 # days + compress: true + - type: syslog # Syslog output + level: WARN + format: text + syslog: + network: unix + address: "" + tag: modular + facility: user +``` + +## Usage + +### Basic Usage with ObservableApplication + +```go +import ( + "github.com/GoCodeAlone/modular" + "github.com/GoCodeAlone/modular/modules/eventlogger" +) + +func main() { + // Create application with observer support + app := modular.NewObservableApplication(configProvider, logger) + + // Register event logger module + app.RegisterModule(eventlogger.NewModule()) + + // Initialize application - event logger will auto-register as observer + if err := app.Init(); err != nil { + log.Fatal(err) + } + + // Now all application events will be logged + app.RegisterModule(&MyModule{}) // Logged as module.registered event + app.Start() // Logged as application.started event +} +``` + +### Manual Observer Registration + +```go +// Get the event logger service +var eventLogger *eventlogger.EventLoggerModule +err := app.GetService("eventlogger.observer", &eventLogger) +if err != nil { + log.Fatal(err) +} + +// Register with any subject for specific event types +err = subject.RegisterObserver(eventLogger, "user.created", "order.placed") +if err != nil { + log.Fatal(err) +} +``` + +### Event Type Filtering + +```go +// Configure to only log specific event types +config := &eventlogger.EventLoggerConfig{ + EventTypeFilters: []string{ + "module.registered", + "service.registered", + "application.started", + "application.failed", + }, +} +``` + +## Output Formats + +### Text Format +Human-readable single-line format: +``` +2024-01-15 10:30:15 INFO [module.registered] application Module 'auth' registered (type=AuthModule) +``` + +### JSON Format +Machine-readable JSON format: +```json +{"timestamp":"2024-01-15T10:30:15Z","level":"INFO","type":"module.registered","source":"application","data":{"moduleName":"auth","moduleType":"AuthModule"},"metadata":{}} +``` + +### Structured Format +Detailed multi-line structured format: +``` +[2024-01-15 10:30:15] INFO module.registered + Source: application + Data: map[moduleName:auth moduleType:AuthModule] + Metadata: map[] +``` + +## Output Targets + +### Console Output +Outputs to stdout with optional color coding and timestamps: + +```yaml +outputTargets: + - type: console + level: INFO + format: structured + console: + useColor: true # ANSI color codes for log levels + timestamps: true # Include timestamps in output +``` + +### File Output +Outputs to files with automatic rotation: + +```yaml +outputTargets: + - type: file + level: DEBUG + format: json + file: + path: /var/log/events.log + maxSize: 100 # MB before rotation + maxBackups: 5 # Number of backup files to keep + maxAge: 30 # Days to keep files + compress: true # Compress rotated files +``` + +### Syslog Output +Outputs to system syslog: + +```yaml +outputTargets: + - type: syslog + level: WARN + format: text + syslog: + network: unix # unix, tcp, udp + address: "" # For tcp/udp: "localhost:514" + tag: modular # Syslog tag + facility: user # Syslog facility +``` + +## Event Level Mapping + +The module automatically maps event types to appropriate log levels: + +- **ERROR**: `application.failed`, `module.failed` +- **WARN**: Custom warning events +- **INFO**: `module.registered`, `service.registered`, `application.started`, etc. +- **DEBUG**: `config.loaded`, `config.validated` + +## Performance Considerations + +- **Async Processing**: Events are processed asynchronously to avoid blocking the application +- **Buffering**: Events are buffered in memory before writing to reduce I/O overhead +- **Error Isolation**: Failures in one output target don't affect others +- **Graceful Degradation**: Buffer overflow results in dropped events with warnings + +## Error Handling + +The module handles various error conditions gracefully: + +- **Output Target Failures**: Logged but don't stop other targets +- **Buffer Overflow**: Oldest events are dropped with warnings +- **Configuration Errors**: Reported during module initialization +- **Observer Errors**: Logged but don't interrupt event flow + +## Integration with Existing EventBus + +The EventLogger module complements the existing EventBus module: + +- **EventBus**: Provides pub/sub messaging between modules +- **EventLogger**: Provides structured logging of Observer pattern events +- **Use Together**: EventBus for inter-module communication, EventLogger for audit trails + +## Testing + +The module includes comprehensive tests: + +```bash +cd modules/eventlogger +go test ./... -v +``` + +## Implementation Notes + +- Uses Go's `log/syslog` package for syslog support +- File rotation could be enhanced with external libraries like `lumberjack` +- Async processing uses buffered channels and worker goroutines +- Thread-safe implementation supports concurrent event logging +- Implements the Observer interface for seamless integration \ No newline at end of file diff --git a/modules/eventlogger/config.go b/modules/eventlogger/config.go new file mode 100644 index 00000000..aa510421 --- /dev/null +++
