8 commands

Pro Tips

Use '--minify' for production builds with smaller output.

'--compile' creates a standalone executable from your code.

Use '--splitting' for code splitting with multiple entry points.

Common Mistakes

Bun's bundler is newer than esbuild/webpack - test output thoroughly.

Some bundler plugins from other ecosystems won't work with Bun.
