A First Look at Bun: Will It Take Node’s Crown?

• bun

  286 70,251 10.0 Zig

  Incredibly fast JavaScript runtime, bundler, test runner, and package manager – all in one

  

  Being in the beta stage, however, means that Bun still has some quirks:

• webpack

  329 64,145 9.8 JavaScript

  A bundler for javascript and friends. Packs many modules into a few bundled assets. Code Splitting allows for loading parts of the application on demand. Through "loaders", modules can be CommonJs, AMD, ES6 modules, CSS, Images, JSON, Coffeescript, LESS, ... and your custom stuff.

  

  After removing and re-adding webpack](https://webpack.js.org/) 10 times with each tool, I got the following results:

• WorkOS

  workos.com

  sponsored

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  

• oha

  3 3,810 9.3 Rust

  Ohayou(おはよう), HTTP load generator, inspired by rakyll/hey with tui animation.

  Bun’s runtime does include a working HTTP server, which presents a benchmarking opportunity to compare with Node and Deno. For the test, I’ll use Bun’s example scripts to drive the tests. I'll generate and measure traffic with oha.

• hyperfine

  74 19,777 8.2 Rust

  A command-line benchmarking tool

  hyperfine: v1.14.0

• deno

  448 92,841 9.9 Rust

  A modern runtime for JavaScript and TypeScript.

  

  Bun is the newest addition to the JavaScript runtime family. It has been making waves that rival those made by Deno when it came out in 2018. Bun sits in the space between Node and Deno. Bun, like Deno, supports TypeScript out of the box and offers developer-friendly features such as top-level awaits and built-in Web APIs. But, unlike Deno, Bun is intended to be a drop-in replacement for Node, Webpack, Babel, Yarn, and PostCSS — all in one neat package.

  1 1 2.7 Shell

  Benchmarks comparing Bun, Node, and Deno for different tasks

• semaphore-demo-javascript

  1 21 5.5 TypeScript

  A Semaphore demo CI/CD pipeline using Node.js, TypeScript, Nest.js and React.

  

  I’ve configured two branches on Semaphore's JavaScript demo project:
