Bun

Trying Bun

As a software engineer, I'm constantly on the lookout for tools that make development faster, cleaner, and more enjoyable. Two weeks ago, I stumbled across Bun and decided to give it a try. I had heard the buzz, but I was skeptical.

I mean, how many times have we seen new JavaScript stuff pop up, only to fade into obscurity? But after a few hours of tinkering, I was genuinely impressed.

Why I love it so much

Bun isn't just a runtime, but for some reason it has everything you need to build cool stuff.

  • Blazingly fast: Startup and execution times blew me away. It made my scripts feel snappy in a way Node just doesn’t.
  • Incredible tooling: You get built-in bundling, testing, packaging (and a runner called bunx), websockets, templating (with React too), and native bindings for databases!
  • Drop-in replacement: It just works. (Almost, not everything is supported yet, but the most important stuff is.) You can likely run your existing Node.js code with Bun without any changes.

Should You Switch?

If you're deep in a Node or Deno setup, I'm not saying you need to rewrite everything overnight. But I am saying you should give Bun a shot on your next small project or script.
