tsup

Basic Bundling

This command bundles the TypeScript file located at `src/index.ts` into CommonJS and ES Module formats. Tsup automatically handles the TypeScript compilation and output generation.

tsup src/index.ts --format cjs,esm

Minification

This command bundles and minifies the TypeScript file located at `src/index.ts`. Minification reduces the file size by removing unnecessary whitespace and comments, making the output more efficient for production use.

tsup src/index.ts --minify

Watch Mode

This command enables watch mode, which automatically rebundles the TypeScript file located at `src/index.ts` whenever changes are detected. This is useful for development environments where you want to see changes in real-time.

tsup src/index.ts --watch

Custom Entry Points

This command allows you to specify multiple entry points for bundling. In this example, both `src/index.ts` and `src/worker.ts` are bundled into ES Module format. This is useful for projects with multiple entry files.

tsup src/index.ts src/worker.ts --format esm

Environment Variables

This command allows you to define environment variables that can be used within your TypeScript code. In this example, `PROCESS_ENV` is set to `production`, which can be used for conditional logic in the code.

tsup src/index.ts --define.PROCESS_ENV=production
