Rules

Bun Dev Tooling · balanced balanced

- Use `bun install` for fast dependency installation with native lockfile (`bun.lockb`) — 10-100x faster than npm/yarn.

- Use `bunx` instead of `npx` for one-off package execution — Bun's package runner has near-instant startup.

- Use `bun build` for bundling TypeScript/JSX without a separate bundler — Bun handles transpilation and tree-shaking natively.

- Use Bun's built-in bundler (`bun build`) instead of webpack/esbuild/rollup.

- Use `bunx` instead of `npx` for running CLI tools.

- Use `bun --hot` for development server hot reloading.

- Use `bun build --compile` to create standalone executables.
