UNPKG is a fast, global content delivery network that provides a seamless experience for everything on npm. It offers a convenient way to load any file from any package using a simple URL structure. For example, you can easily access files like react.

production. min. js and react-dom.

production. min. js by specifying the package and version.

Using UNPKG, you have the flexibility to use a fixed version, a semver range, or a tag to retrieve files. If you omit the file path, UNPKG will serve the file specified in the package. json file or fallback to the main file.

Additionally, UNPKG allows you to view a comprehensive listing of all the files in a package by appending a forward slash at the end of the URL. The CDN's cache behavior ensures efficient and reliable delivery, with files being cached indefinitely and redirects being cached for a short time. This enables users to access the latest version quickly.

For npm package authors, UNPKG simplifies the process of publishing code to a CDN along with the npm registry. By including the UMD build in the npm package and following a straightforward setup, authors can make their code available on UNPKG upon publishing. UNPKG is an open source project supported by Michael Jackson, not affiliated with npm, Inc.

It leverages Cloudflare's cloud network platform and benefits from auto-scaling infrastructure provided by Fly. io. Discover the power and convenience of UNPKG, the ultimate CDN for npm
