Fastpack is a fast JavaScript module bundler written in OCaml, designed to pack JS code into a single bundle with speed as the primary goal. It supports loaders (e.g., Babel, CSS), watch mode, and persistent caching, positioning itself as a faster alternative to Webpack and Parcel.

Use cases

• bundle a javascript application into a single file
• faster alternative to webpack for bundling js modules
• build a react app with babel and css loaders
• watch mode rebuilds for javascript development
• bundle 1600+ modules quickly with persistent cache

When to choose

• you need very fast bundling of JavaScript modules
• you want webpack-like loaders (babel, css) with simpler configuration
• your project benefits from persistent caching and fast watch mode

When to avoid

• you need a mature ecosystem with extensive plugins and community support
• you require modern features like ESM output, code splitting, or tree shaking that newer bundlers offer
• the project appears to receive infrequent updates
