Introduction | Bunup
Bunup is the ⚡️ blazing-fast build tool for TypeScript libraries, designed for flawless developer experience and speed, powered by Bun.
Bunup delivers instant builds by design. With Bun's native speed and Bunup's own high-performance dts bundler, cold starts and rebuilds are lightning fast, even in monorepos. Say goodbye to slow bundling and say hello to instant packaging. See benchmarks.
That's it! This creates bundled output in the dist directory with ESM format (the default), plus TypeScript declaration files (.d.ts) since the entry point is a TypeScript file.
Create a bunup.config.ts file for more advanced usage like including plugins, hooks, and advanced options that aren't available via CLI.
For example, you can add the exports plugin to automatically sync your package.json exports on each build - no more manual export management!
Bunup provides a JSON schema at https://bunup.dev/schema.json for editor autocompletion and validation. You can enable autocomplete for the bunup field in your package.json by configuring VSCode:
