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.

  • Hosting a Production-Level Discord Bot: Python, Bun, Rust, and the Cheapest Way to Scale
    The Node.js ecosystem has powered bots for a decade via discord.js. However, the Bun runtime has completely changed the game. Bun acts as an all-in-one JavaScript toolkit that starts up significantly faster and utilizes memory far more efficiently than standard Node.js. - Source: dev.to / 22 days ago
  • No SQLite driver works in both Bun and Node. Here is how I shipped one package that runs on both.
    The binary had a #!/usr/bin/env bun shebang and imported bun:sqlite. I had developed the whole thing under Bun, so on my machine it was perfect. On a normal machine with only Node installed, there is no bun to run the shebang, the entry was a .ts file Node would not execute, and even if it got that far, bun:sqlite is a built-in that only exists inside Bun. Three separate ways to fail before any of my code ran.... - Source: dev.to / about 2 months ago
  • Polly wants a transcript: giving agents ears and a voice, on your own machine
    The CLI is a thin Bun wrapper; the engine is the Rust binary it shells out to. Pipe-friendly by design โ€” transcript on stdout, errors on stderr. - Source: dev.to / about 2 months ago
  • Why Bun is Rewriting in Rust (And What It Means for JavaScript Developers)
    The numbers are striking. According to benchmarks published on bun.sh, Bun handles 59,026 Express.js "hello world" HTTP requests per second on Linux x64, compared to 25,335 for Deno and 19,039 for Node.js. For WebSocket throughput, Bun clocks 2,536,227 messages per second against Deno's 1,320,525 and Node's 435,099. Bun also bundles 10,000 React components in 269ms. Rolldown completes the same job in 495ms.... - Source: dev.to / 2 months ago
  • My fully offline AI-assisted Linux development machine
    Toolchains: I use SDKMAN! For JDKs, NVM for Node.js, rustup for Rust, Bun, Go, Python, Deno, and the usual Linux build tools. - Source: dev.to / 3 months ago
