Why I Love Bun

I switched from Node.js to Bun about a year ago and I haven't looked back. It's fast, it's batteries-included, and the developer experience is simply better.

It's stupid fast

Package installs that used to take 30 seconds with npm take under 5 with Bun. Cold starts are near-instant. If you're running scripts or lightweight servers, the difference is night and day.

One tool for everything

Bun is a runtime, package manager, bundler, and test runner all in one. You don't need to configure webpack, jest, or a separate package manager. Just bun run, bun test, bun add — that's the whole mental model.

Hono pairs perfectly with it

I've been using Hono as my web framework of choice when building APIs with Bun. It's lightweight, typed, and has great middleware support. The combo of Bun + Hono feels like what Express should have been.

import { Hono } from "hono";

const app = new Hono();

app.get("/", (c) => c.text("Hello from Bun!"));

export default app;

Should you switch?

If you're building new projects, absolutely try Bun. It's production-ready and the ecosystem support keeps getting better. The only caveat is some native Node.js modules that rely on C++ bindings — check compatibility first if that's a concern.

But for the vast majority of web projects? Bun is the move.
