+# E-commerce Channel Types - Comprehensive Example
+
+A comprehensive example showing how to generate type-safe channel routing from AsyncAPI specifications for an e-commerce event system. This example demonstrates all the patterns from the accompanying [blog post](https://the-codegen-project.org/blog/asyncapi-types-generator).
+
+**Files:**
+- `ecommerce-channels.yaml` - AsyncAPI specification defining event channels and routing
+- `codegen.config.js` - Configuration for generating TypeScript channel types
+- `src/index.ts` - Comprehensive demo showcasing all blog post examples
+
+**Features demonstrated:**
+- **Type-Safe Event Publisher** - Publish events with compile-time channel validation
+- **Type-Safe Event Router** - Route events to handlers with type safety
+- **Message Broker Integration** - Examples for NATS and Kafka
+- **Environment-Specific Channel Mapping** - Add environment prefixes
+- **Channel Health Monitoring** - Track publishing metrics and error rates
+- **Parameter Substitution** - Dynamic channel addresses with entity IDs
+- **Error Handling** - Runtime validation with proper error handling
+
+**Usage:**
+```bash
+# Install dependencies
+npm install
+
+# Generate channel types from AsyncAPI spec
+npm run generate
+
+# Run the comprehensive demo showcasing all patterns
+npm run demo
+```
+
+The generated types can be used with any messaging infrastructure (NATS, Kafka, RabbitMQ, etc.) while providing compile-time safety for channel routing.
