JSR
JSR is a modern package registry designed specifically for TypeScript and ECMAScript modules. It allows developers to publish native TypeScript source code while automatically generating type definition files, API documentation, and handling runtime transpilation. JSR functions as a superset of the traditional npm ecosystem, remaining compatible with standard package managers and working seamlessly across multiple runtimes including Node.js, Deno, Bun, and Cloudflare Workers.
