Bun 1.0 is finally here

Bun is a fast, all-in-one toolkit for running, building, testing, and debugging JavaScript and TypeScript, from a single file to a full-stack application.

Today, Bun is stable and production-ready.

According to bun official blogpost, bun’s goal is simple: eliminate slowness and complexity without throwing away everything that’s great about JavaScript. Your favorite libraries and frameworks should still work, and you shouldn’t need to unlearn the conventions you’re familiar with.

Some of the reasons to try bun today !

Node.js compatibility

Bun is a drop-in replacement for Node.js. That means existing Node.js applications and npm packages just work in Bun.

Speed

Bun is fast, starting up to 4x faster than Node.js. This difference is only magnified when running a TypeScript file, which requires transpilation before it can be run by Node.js.

TypeScript and JSX support

Bun has a JavaScript transpiler that’s baked into the runtime. That means you can run JavaScript, TypeScript, and even JSX/TSX files, no dependencies needed

ESM & CommonJS compatibility

Bun supports both module systems, all the time. No need to worry about file extensions, .js vs .cjs vs .mjs, or including "type": "module" in your package.json.

You can even use import and require(), in the same file and it should work fine.

Web APIs

Bun has built-in support for the Web standard APIs that are available in browsers, such as fetch, Request, Response, WebSocket, and ReadableStream.

Hot reloading

Bun makes it easier for you to be productive as a developer. You can run Bun with --hot to enable hot reloading, which reloads your application when files change.
