Meet Bun

Bun combines a JavaScript runtime, package manager, test runner, and bundler in a single executable. It runs JavaScript and TypeScript, supports Node.js APIs and npm packages, and lets developers adopt individual tools in an existing project. A team can use its package installer or testing commands without moving the entire application to a different runtime.

The toolkit includes development-server support, hot reloading, and bundling for browser and server code. Applications can also be compiled into standalone executables for distribution. Bun is useful for developers who want installation, local development, testing, and packaging to share a consistent set of commands and configuration.
