Bun
Fast all-in-one JavaScript and TypeScript runtime that also ships a package manager, test runner and bundler as one executable.
Bun is a JavaScript and TypeScript runtime written in Rust, shipped as one executable that also contains a package manager, a test runner and a bundler. The runtime is described as a drop-in replacement for Node.js, and the bundler is started with the bun build command or the Bun.build() API. It is installed with a shell script, npm, Homebrew or a Docker image. The project’s homepage states that Bun has joined Anthropic, and the code is maintained in the oven-sh GitHub organization.
Worth knowing
