Simplify AWS Lambda Routing with Zapix – A Lightweight TypeScript Router

#api #serverless #typescript #aws

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

Middleware & Handlers – chain multiple middlewares before hitting your main controller.
Centralized Error Handling – catch validation errors, JS errors, and more in one place.
Type Safety – request and response objects are strongly typed.
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);
