Introduction

Serve0 is a programmable edge gateway and reverse proxy designed for modern microservices architectures.

Why Serve0?​

Standard proxies like Nginx are powerful but hard to extend with custom logic. AWS API Gateway is expensive and vendor-locked.

Serve0 offers:

  • TypeScript First: Write middleware and plugins in full TypeScript.
  • Modular: Pick only the modules you need (Auth, RateLimit, Cache).
  • Edge Ready: Designed to run on lightweight edge/serverless runtimes.

Key Features​

  • 🔐 Authentication: Built-in JWT and API Key support.
  • 🚦 Rate Limiting: Redis-backed distributed rate limiting.
  • ⚡ Caching: Smart caching strategies for high performance.
  • 🔍 Observability: Integrated logging and metrics.

Quick Start​

import { Serve0 } from '@serve0/core';
import { RateLimit } from '@serve0/ratelimit';

const app = new Serve0();

app.use(RateLimit({ window: '1m', limit: 100 }));

app.get('/api', (ctx) => {
  return { message: 'Hello from Edge' };
});

app.listen(3000);
