Bun.js - Fresh JavaScript runtime out of the oven 🧑‍🍳

When JS devs got bored of rebuilding libraries, they started rebuilding the runtime.

An all-in-one JavaScript runtime

A few weeks ago, Jared Sumner released Bun.js—an all-in-one runtime for JavaScript. Bun includes a native bundler, TypeScript transpiler, task runner, and npm client.

And it is fast. ⚡

Since Bun is an all-in-one tool, performance is not limited to apps. Developer tooling also benefit from it:

• 4.5x faster starts than node
• 30x faster script runs than npm
• 20x faster installs than yarn

On top of all, Bun has full compatibility with all the NPM ecosystem. So there's little to no migration needed. ✅

Should we use Bun?

By all means, try it out! Bun.js looks extremely promising. Its sheer performance could be driving change across the entire JS ecosystem; the same way Vite changed the face of front-end dev in a couple months.

Personally, I'd love to see more tools aim at running on the edge.

But Bun still has to come to grips with:

• Project scoping—A monumental scope is not a bad thing per se, but it makes the challenge greater
• Sustainable maintaining—Building a team around the creator is vital to ensuring continuous development and support
• The Zig question—Bun is built with the Zig language which is quite unproven in the industry
