Bun is a new JavaScript runtime built from scratch to serve the modern JavaScript ecosystem. It has three major design goals:

  1. Speed. Bun starts fast and runs fast. It extends JavaScriptCore, the performance-minded JS engine built for Safari. As computing moves to the edge, this is critical.

  2. Elegant APIs. Bun provides a minimal set of highly-optimimized APIs for performing common tasks, like starting an HTTP server and writing files.

  3. Cohesive DX. Bun is a complete toolkit for building JavaScript apps, including a package manager, test runner, and bundler.

Bun is designed as a drop-in replacement for Node.js. It natively implements hundreds of Node.js and Web APIs, including fs, path, Buffer and more.

The goal of Bun is to run most of the world's server-side JavaScript and provide tools to improve performance, reduce complexity, and multiply developer productivity.

  • React Server Components Example with Next.js
    At Node Conference 2023, Jarred Sumner (creator of Bun) showed a demo of server components in Bun, so there is at least partial support in that ecosystem. The Bun repo provides bun-plugin-server-components as the official plugin for server components. And while I haven’t looked at it in-depth, Marz claims to be a “React Server Components Framework for Bun”. - Source: dev.to / 14 days ago
