Simplify AWS Lambda Routing with Zapix – A Lightweight TypeScript Router

If you’re building serverless applications on AWS Lambda, handling routing, middleware, and errors can quickly get messy. Enter Zapix – a lightweight, TypeScript-friendly router designed specifically for Lambda.

Why Zapix?

• Minimal router supporting get, post, put, patch, delete, options, and all methods


• 
  Middleware chaining similar to Express.js – validate, authenticate, or transform requests easily


• 
  Global error handling with router.useError for centralized control


• 
  Safe and consistent HTTP responses with the Response() utility


• Fully typed for TypeScript, providing IntelliSense and safer code

Key Features

1. 
   Middleware & Handlers – chain multiple middlewares before hitting your main controller.


2. 
   Centralized Error Handling – catch validation errors, JS errors, and more in one place.


3. 
   Type Safety – request and response objects are strongly typed.


4. 
   Utilities – safeJsonParse for JSON safety and Response() for unified responses.

Getting Started

Install Zapix via npm:

npm install zapix

Example usage:

import { Router, Handler } from 'zapix';



const router = new Router();



router.post('/users', createUser);

router.get('/users', readUsers);

router.get('/users/{userId}', readUserInfo);

router.put('/users/{userId}', updateUser);

router.delete('/users/{userId}', deleteUser);



// Fallback route

router.all(() => ({

  statusCode: 404,

  body: JSON.stringify({ error: 'Route not found' }),

}));



export const handler = Handler(router);

Zapix makes it simple to write clean, maintainable Lambda functions without losing type safety or flexibility.
