bunWay

Run everything. The Bun way. bunWay is an open-source experiment to recreate the ergonomics of Express on top of Bun’s native runtime. If you moved to Bun for its speed and modern APIs but miss the familiar middleware/route flow, this toolkit is for you.

Overview

• Built entirely on Bun’s Request/Response objects.
• Familiar (ctx, next) middleware signature and bunway() factory.
• Ships batteries included: json, urlencoded, text, cors, and errorHandler middleware.
• TypeScript-first with generated .d.ts files and TypeDoc reference.

Goal

Give Bun developers the nostalgic Express flow without leaving the Bun runtime. No Node polyfills, no surprises—just Bun-native speed with a welcoming API.

Quick usage

import { bunway, cors, json, errorHandler, HttpError } from "bunway";

const app = bunway();
app.use(cors({ origin: true }));
app.use(json());
app.use(errorHandler({ logger: console.error }));

app.get("/", (ctx) => ctx.res.text("Hello from bunway"));
app.get("/users/:id", (ctx) => {
  const id = ctx.req.param("id");
  if (!id) throw new HttpError(404, "User not found");
  return ctx.res.json({ id });
});

app.listen({ port: 7070 });
