- Bundle with source maps for debugging:

`bun build {{path/to/entry.ts}} --outfile {{path/to/output.js}} --sourcemap`

- Bundle with minification for production:

`bun build {{path/to/entry.ts}} --outfile {{path/to/output.js}} --minify`

- Bundle with a specific target environment:

`bun build {{path/to/entry.ts}} --outfile {{path/to/output.js}} --target {{browser|bun|node}}`

- Bundle to a standalone executable:

`bun build {{path/to/entry.ts}} --compile --outfile {{path/to/executable}}`
