+This example demonstrates the base configuration support in the Modular framework, allowing you to manage configuration across multiple environments efficiently. + +## Directory Structure + +The example uses the following configuration structure: + +``` +config/ +├── base/ +│ └── default.yaml # Baseline config shared across all environments +└── environments/ + ├── prod/ + │ └── overrides.yaml # Production-specific overrides + ├── staging/ + │ └── overrides.yaml # Staging-specific overrides + └── dev/ + └── overrides.yaml # Development-specific overrides +``` + +## How It Works + +1. **Base Configuration**: The `config/base/default.yaml` file contains shared configuration that applies to all environments +2. **Environment Overrides**: Each environment directory contains `overrides.yaml` files that override specific values from the base configuration +3. **Deep Merging**: The framework performs deep merging, so you only need to specify the values that change per environment + +## Running the Example + +### Prerequisites + +```bash +cd examples/base-config-example +go mod tidy +``` + +### Run with Different Environments + +```bash +# Run with development environment (default) +go run main.go dev + +# Run with staging environment +go run main.go staging + +# Run with production environment +go run main.go prod +``` + +### Using Environment Variables + +You can also set the environment using environment variables: + +```bash +# Using APP_ENVIRONMENT +APP_ENVIRONMENT=prod go run main.go + +# Using ENVIRONMENT +ENVIRONMENT=staging go run main.go + +# Using ENV +ENV=dev go run main.go +``` + +## Configuration Differences by Environment + +### Development (dev) +- Simple database password +- Debug features enabled +- Caching disabled for easier debugging +- Basic server configuration + +### Staging (staging) +- Staging database host +- Metrics enabled for testing +- Redis enabled +- Medium server load capacity + +### Production (prod) +- Production database with secure password +- Metrics enabled, debug disabled +- All external services enabled (Redis, RabbitMQ) +- High server capacity and HTTPS port + +## Key Benefits + +1. **DRY Principle**: Common configuration is defined once in base config +2. **Environment Specific**: Only differences need to be specified per environment +3. **Easy Maintenance**: Adding new environments only requires creating override files +4. **Version Control Friendly**: Clear separation between base and environment-specific configs +5. **Deep Merging**: Nested objects are merged intelligently + +## Example Output + +When you run the example, you'll see the final merged configuration showing how base values are combined with environment-specific overrides: + +``` +=== Base Configuration Example === + +Running in environment: prod + +=== Final Configuration === +App Name: Base Config Example +Environment: production + +Database: + Host: prod-db.example.com + Port: 5432 + Name: prod_app_db + Username: app_user + Password: su********************* + +Server: + Host: localhost + Port: 443 + Timeout: 60 seconds + Max Connections: 1000 + +Features: + caching: enabled + debug: disabled + logging: enabled + metrics: enabled + +External Services: + Redis: enabled (Host: prod-redis.example.com:6379) + RabbitMQ: enabled (Host: prod-rabbitmq.example.com:5672) +``` + +## Integration with Existing Apps + +To use base configuration support in your existing Modular applications: + +1. **Create the directory structure**: + ```bash + mkdir -p config/base config/environments/prod config/environments/staging + ``` + +2. **Move your existing config** to `config/base/default.yaml` + +3. **Create environment overrides** in `config/environments/{env}/overrides.yaml` + +4. **Enable base config support** in your application: + ```go + // Set base configuration support + modular.SetBaseConfig("config", environment) + + // Or let the framework auto-detect the structure + app := modular.NewStdApplication(configProvider, logger) + ``` + +The framework will automatically detect the base config structure and enable the feature if you don't explicitly set it up. \ No newline at end of file diff --git a/examples/base-config-example/config/base/default.yaml b/examples/base-config-example/config/base/default.yaml new

Services Not Available + +If you see messages like "❌ Redis engine not available" or "❌ Kafka engine not available": + +1. **Check if Docker is running**: `docker --version` +2. **Start the services**: `./run-demo.sh start` +3. **Check service status**: `./run-demo.sh status` +4. **View service logs**: `./run-demo.sh logs` + +### Common Issues + +**Port conflicts**: If ports 6379 (Redis) or 9092 (Kafka) are in use: +```bash +# Check what's using the ports +netstat -tlnp | grep :6379 +netstat -tlnp | grep :9092 + +# Stop conflicting services or modify docker-compose.yml ports +``` + +**Docker Compose version**: The script auto-detects `docker compose` vs `docker-compose`: +```bash +# Check your version +docker compose version # Newer +# or +docker-compose version # Older +``` + +**Services taking too long to start**: +- Redis usually starts in ~10 seconds +- Kafka can take 30-60 seconds due to Zookeeper dependency +- Use `./run-demo.sh logs` to monitor startup progress + +## Key Concepts + +### Engine Registration +```go +// Engines are registered automatically at startup +// Custom engines can be registered with: +eventbus.RegisterEngine("myengine", MyEngineFactory) +``` + +### Topic Routing +```go +// Events are automatically routed based on configured rules +eventBus.Publish(ctx, "user.login", userData) // -> memory-fast +eventBus.Publish(ctx, "analytics.click", clickData) // -> kafka-analytics +eventBus.Publish(ctx, "system.health", healthData) // -> redis-durable +eventBus.Publish(ctx, "custom.event", customData) // -> memory-reliable (fallback) +``` + +### Engine-Specific Configuration +```go +config := eventbus.EngineConfig{ + Name: "my-kafka", + Type: "kafka", + Config: map[string]interface{}{ + "brokers": []string{"localhost:9092"}, + "groupId": "my-consumer-group", + }, +} +``` + +### Service Discovery and Health Checks +```go +// Check which engine will handle a topic +router := eventBus.GetRouter() +engine := router.GetEngineForTopic("analytics.click") // "kafka-analytics" + +// Get active topics and subscriber counts +activeTopics := eventBus.Topics() +for _, topic := range activeTopics { + count := eventBus.SubscriberCount(topic) + fmt.Printf("%s: %d subscribers\n", topic, count) +} +``` + +## Architecture Benefits + +- **Scalability**: Different engines can be optimized for different workloads +- **Reliability**: Critical events can use more reliable engines while fast events use optimized ones +- **Isolation**: Different types of events are processed independently +- **Flexibility**: Easy to add new engines or change routing without code changes +- **Monitoring**: Per-engine metrics and logging for better observability +- **Development**: Complete local development environment with real services +- **Production Ready**: Same configuration works in production with external service endpoints + +## Production Considerations + +### Redis Configuration +```yaml +redis: + url: "redis://prod-redis:6379" + password: "${REDIS_PASSWORD}" + poolSize: 20 + db: 1 +``` + +### Kafka Configuration +```yaml +kafka: + brokers: ["kafka1:9092", "kafka2:9092", "kafka3:9092"] + groupId: "production-consumers" + security: + protocol: "SASL_SSL" + username: "${KAFKA_USERNAME}" + password: "${KAFKA_PASSWORD}" +``` + +### High Availability Setup +- Use Redis Cluster or Sentinel for Redis HA +- Use Kafka clusters with multiple brokers and replicas +- Configure appropriate retention policies +- Set up monitoring and alerting +- Use circuit breakers for external service failures + +## Development Workflow + +1. **Local Development**: Use Docker Compose for local Redis/Kafka +2. **Testing**: Unit tests with mock engines, integration tests with real services +3. **Staging**: Connect to shared staging Redis/Kafka clusters +4. **Production**: Use managed services (ElastiCache, MSK, Confluent, etc.) + +## Advanced Usage + +### Custom Engine Implementation +```go +type MyCustomEngine struct { + // Implementation +} + +func NewMyCustomEngine(config map[string]interface{}) (EventBus, error) { + // Factory function +} + +// Register the engine +eventbus.RegisterEngine("mycustom", NewMyCustomEngine) +``` + +### Multi-Tenant Routing +```go +routing: + - topics: ["tenant1.*"] + engine: "redis-tenant1" + - topics: ["tenant2.*"] + engine: "kafka-tenant2" +``` + +### Environment-Specific Configuration +```go +// Development: Use in-memory engines +// Staging: Use shared Redis/Kafka +// Production: Use managed services with authentication +``` + +## Next Steps + +Try modifying the example to: + +1. **Add custom authentication** for Redis and Kafka +2. **Implement custom event filtering** in engines +3. **Add tenant-aware routing** for multi-tenant applications +4. **Experiment with different partition strategies** in Kafka +5. **Add monitoring and metrics collection** for all engines +6. **Create custom engines** for other message brokers (NATS, RabbitMQ, etc.) +7. **Add event replay and dead letter queue functionality** \ No newline at end of file diff --git a/examples/multi-engine-eventbus/config.yaml

It acts as a decorator around the standard Logger interface to automatically redact sensitive information from log output based on configurable rules. + +## Features + +- **Logger Decorator**: Wraps any `modular.Logger` implementation with masking capabilities +- **Field-Based Masking**: Define rules for specific field names (e.g., "password", "token") +- **Pattern-Based Masking**: Use regex patterns to detect sensitive data (e.g., credit cards, SSNs) +- **MaskableValue Interface**: Allow values to control their own masking behavior +- **Multiple Masking Strategies**: Redact, partial mask, hash, or leave unchanged +- **Configurable Rules**: Full YAML/JSON configuration support +- **Performance Optimized**: Minimal overhead for production use +- **Framework Integration**: Seamless integration with the Modular framework + +## Installation + +Add the logmasker module to your project: + +```bash +go get github.com/GoCodeAlone/modular/modules/logmasker +``` + +## Configuration + +The logmasker module can be configured using the following options: + +```yaml +logmasker: + enabled: true # Enable/disable log masking + defaultMaskStrategy: redact # Default strategy: redact, partial, hash, none + + fieldRules: # Field-based masking rules + - fieldName: password + strategy: redact + - fieldName: email + strategy: partial + partialConfig: + showFirst: 2 + showLast: 2 + maskChar: "*" + minLength: 4 + - fieldName: token + strategy: redact + - fieldName: secret + strategy: redact + - fieldName: key + strategy: redact + + patternRules: # Pattern-based masking rules + - pattern: '\b\d{4}[\s-]?\d{4}[\s-]?\d{4}[\s-]?\d{4}\b' # Credit cards + strategy: redact + - pattern: '\b\d{3}-\d{2}-\d{4}\b' # SSN format + strategy: redact + + defaultPartialConfig: # Default partial masking settings + showFirst: 2 + showLast: 2 + maskChar: "*" + minLength: 4 +``` + +## Usage + +### Basic Usage + +Register the module and use the masking logger service: + +```go +package main + +import ( + "github.com/GoCodeAlone/modular" + "github.com/GoCodeAlone/modular/modules/logmasker" +) + +func main() { + // Create application with your config and logger + app := modular.NewApplication(configProvider, logger) + + // Register the logmasker module + app.RegisterModule(logmasker.NewModule()) + + // Initialize the application + if err := app.Init(); err != nil { + log.Fatal(err) + } + + // Get the masking logger service + var maskingLogger modular.Logger + err := app.GetService("logmasker.logger", &maskingLogger) + if err != nil { + log.Fatal(err) + } + + // Use the masking logger - sensitive data will be automatically masked + maskingLogger.Info("User login", + "email", "user@example.com", // Will be partially masked + "password", "secret123", // Will be redacted + "sessionId", "abc-123-def") // Will remain unchanged + + // Output: "User login" email="us*****.com" password="[REDACTED]" sessionId="abc-123-def" +} +``` + +### MaskableValue Interface + +Create values that control their own masking behavior: + +```go +// SensitiveToken implements MaskableValue +type SensitiveToken struct { + Value string + IsPublic bool +} + +func (t *SensitiveToken) ShouldMask() bool { + return !t.IsPublic +} + +func (t *SensitiveToken) GetMaskedValue() any { + return "[SENSITIVE-TOKEN]" +} + +func (t *SensitiveToken) GetMaskStrategy() logmasker.MaskStrategy { + return logmasker.MaskStrategyRedact +} + +// Usage +token := &SensitiveToken{Value: "secret-token", IsPublic: false} +maskingLogger.Info("API call", "token", token) +// Output: "API call" token="[SENSITIVE-TOKEN]" +``` + +### Custom Configuration + +Override default masking behavior: + +```go +// Custom configuration in your config file +config := &logmasker.LogMaskerConfig{ + Enabled: true, + DefaultMaskStrategy: logmasker.MaskStrategyPartial, + FieldRules: []logmasker.FieldMaskingRule{ + { + FieldName: "creditCard", + Strategy: logmasker.MaskStrategyHash, + }, + { + FieldName: "phone", + Strategy: logmasker.MaskStrategyPartial, + PartialConfig: &logmasker.PartialMaskConfig{ + ShowFirst: 3, + ShowLast: 4, + MaskChar: "#", + MinLength: 10, + }, + }, + }, + PatternRules: []logmasker.PatternMaskingRule{ + { + Pattern: `\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}\b`, // Email regex + Strategy: logmasker.MaskStrategyPartial, + PartialConfig: &logmasker.PartialMaskConfig{ + ShowFirst: 2, + ShowLast: 8, // Show domain + MaskChar: "*", + MinLength: 6, + }, + }, + }, +} +``` + +### Integration with Other Modules + +The logmasker works seamlessly with other modules: + +```go +// In a module that needs masked logging +type MyModule struct { + logger modular.Logger +} + +func (m *MyModule) Init(app modular.Application) error { + // Get the masking logger instead of the original logger + return app.GetService("logmasker.logger", &m.logger) +} + +func (m *MyModule) ProcessUser(user *User) { + // All sensitive data will be automatically masked + m.logger.Info("Processing user", + "id", user.ID, + "email", user.Email, // Masked based on field rules + "password", user.Password, // Redacted + "profile", user.Profile) // Unchanged +} +``` + +## Masking Strategies + +### Redact Strategy +Replaces the entire value with `[REDACTED]`: +``` +password: "secret123" → "[REDACTED]" +``` + +### Partial Strategy +Shows only specified characters, masking the rest: +``` +email: "user@example.com" → "us**********com" (showFirst: 2, showLast: 3) +phone: "555-123-4567" → "555-***-4567" (showFirst: 3, showLast: 4) +``` + +### Hash Strategy +Replaces value with a hash: +``` +token: "abc123" → "[HASH:2c26b46b]" +``` + +### None Strategy +Leaves the value unchanged (useful for overriding default behavior): +``` +publicId: "user-123" → "user-123" +``` + +## Field Rules vs Pattern Rules + +- **Field Rules**: Match exact field names in key-value logging pairs +- **Pattern Rules**: Match regex patterns in string values regardless of field name + +Field rules take precedence over pattern rules for the same value. + +## Performance Considerations + +- **Lazy Compilation**: Regex patterns are compiled once during module initialization +- **Early Exit**: When masking is disabled, no processing overhead occurs +- **Efficient Matching**: Field rules use map lookup, pattern matching is optimized +- **Memory Efficient**: No unnecessary string copies for unmasked values + +## Error Handling + +The module handles various error conditions gracefully: + +- **Invalid Regex Patterns**: Module initialization fails with descriptive error +- **Missing Logger Service**: Module initialization fails if logger service unavailable +- **Configuration Errors**: Reported during module initialization +- **Runtime Errors**: Malformed log calls are passed through unchanged + +## Security Considerations + +When using log masking in production: + +- **Review Field Rules**: Ensure all sensitive field names are covered +- **Test Pattern Rules**: Validate regex patterns match expected sensitive data +- **Audit Log Output**: Regularly review logs to ensure masking is working +- **Performance Impact**: Monitor performance in high-throughput scenarios +- **Configuration Security**: Ensure masking configuration itself doesn't contain secrets + +## Testing + +Run the module tests: + +```bash +cd modules/logmasker +go test ./... -v +``` + +The module includes comprehensive tests covering: +- Field-based masking rules +- Pattern-based masking rules +- MaskableValue interface behavior +- All masking strategies +- Partial masking configuration +- Module lifecycle and integration +- Performance edge cases + +## Implementation Notes + +- The module wraps the original logger using the decorator pattern +- MaskableValue interface allows for anytype-compatible value wrappers +- Configuration supports full validation with default values +- Regex patterns are pre-compiled for performance +- The module integrates seamlessly with the framework's service system + +## Integration with Existing Logging + +The logmasker module is designed to be a drop-in replacement for the standard logger: + +```go +// Before: Using standard logger +var logger modular.Logger +app.GetService("logger", &logger) + +// After: Using masking logger +var maskingLogger modular.Logger +app.GetService("logmasker.logger", &maskingLogger) + +// Same interface, automatic masking +maskingLogger.Info("message", "key", "value") +``` + +This allows existing code to benefit from masking
