Package Exports
- aws-events-adapter
- aws-events-adapter/dist/index.js
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (aws-events-adapter) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
aws-events-adapter
aws-events-adapter is an npm package written in TypeScript that allows you to handle and dispatch multiple types of AWS events to your Lambda functions, with a unified routing pattern.
Features
- 🔄 Supports multiple AWS event types (EventBridge, ApiGateway, Lambda, SQS, etc).
- 🛠️ Automatic routing to the correct handler based on event type and details.
- 📦 TypeScript-first for safety and maintainability.
- 🚀 Easy integration in serverless projects.
Installation
npm install aws-events-adapter
or
yarn add aws-events-adapter
Usage
You define a routing object (DispatchRoutes
) that maps each AWS event type to its handler(s):
API Gateway Routing
Route by HTTP method and path:
import { DispatchRoutes } from 'aws-events-adapter';
const apigateway = {
get: {
'/user': async (event) => ({ statusCode: 200, body: 'User GET!' }),
},
post: {
'/user': async (event) => ({ statusCode: 201, body: 'User created!' }),
},
};
EventBridge Routing
Route by operationName
inside event.detail.operationName
:
const eventbridge = {
hello: async (event) => ({ statusCode: 200, body: 'Hello from EventBridge!' }),
bye: async (event) => ({ statusCode: 200, body: 'Goodbye from EventBridge!' }),
default: async (event) => ({ statusCode: 400, body: 'Operation not supported' })
};
Lambda and SQS Routing
Route by handler name:
const lambda = {
default: async (event) => ({ statusCode: 200, body: 'Lambda default handler' }),
};
const sqs = {
default: async (event) => ({ statusCode: 200, body: 'SQS default handler' }),
};
Integrating with your Lambda
import { dispatchEvent } from 'aws-events-adapter';
import { apigateway, eventbridge, lambda, sqs } from './routes';
const routes = { apigateway, eventbridge, lambda, sqs };
export const handler = async (event, context) => {
return dispatchEvent(event, routes);
};
Example EventBridge Event
{
"source": "EVENT_BRIDGE",
"detail": {
"operationName": "hello",
"data": { "foo": "bar" }
}
}
