The new ultra-fast runtime challenges the king.
Node.js has been the default JavaScript runtime for over a decade. But Bun is here, written in Zig, claiming to be a drop-in replacement that is drastically faster. Is it time to switch?
I am fast. 3x faster startup. 4x faster HTTP server. I'm written in Zig and use JavaScriptCore. You are V8 and C++. Old tech.
I run the internet. Netflix, Uber, NASA... they run on me. I am battle-tested. You are new. Can you guarantee you won't segfault in production?
I am an all-in-one toolkit. I have a bundler, a test runner, a package manager (bun install is instant!), and a runtime. You need npm, jest, webpack, nodemon... bloat everywhere.
My ecosystem is vast. Not every npm package works with you yet. I have 10 years of edge case handling built in.
I support TypeScript out of the box. No `ts-node`, no build step. Just `bun run index.ts`. It's how it should have always been.
Bun is incredibly exciting and offers a superior developer experience for new projects. However, Node.js remains the safe, stable choice for mission-critical production environments.
