Bun.js - Fresh JavaScript runtime out of the oven πŸ§‘β€πŸ³

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.jsβ€”an all-in-one runtime for JavaScript. Bun includes a native bundler, TypeScript transpiler, task runner, and npm client.

And it is fast. ⚑

Bun benchmark

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

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

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

Dig further by reading Bun.js documentation.
