Installation

Install routup as a dependency. Runtime adapters are included automatically.

npm install routup

Basic Setup

import { App, defineCoreHandler, serve } from 'routup';

const app = new App();

app.get('/', defineCoreHandler((event) => {
    return 'Hello, World!';
}));

serve(app, { port: 3000 });

The correct runtime (Node.js, Bun, Deno, etc.) is selected automatically via conditional exports. All core exports (App, defineCoreHandler, defineErrorHandler, helpers, etc.) and the runtime-specific serve() function are available from a single routup import.

See Runtime Environments for runtime-specific details and explicit entry points.
