⚡️ H3 on the edge

This repo contains examples of unjs/h3 integration with popular runtime platforms.

H3 Web Adapter

With h3 (>= 1.8) you can easily integrate your app with any runtime platform supporting Fetch API (Request => Response).

import { createApp, eventHandler, toWebHandler } from "h3"; // or "https://esm.sh/h3@1.8.0"

const app = createApp();

app.use(
  "/",
  eventHandler((event) => "H3 works on edge!"),
);

// (Request) => Promise<Response>
const webHandler = toWebHandler(app);

You can virtually return anything from an event handler including web ReadableStream and Response!

See ./src/index.ts for main application and each platform details in next section.
