unpkg is a fast, global content delivery network for everything on npm. Use it to quickly and easily load any file from any package using a URL like:
unpkg.com/:package@:version/:file
Examples
Using a fixed version:
unpkg.com/react@16.0.0/umd/react.production.min.js
unpkg.com/react-dom@16.0.0/umd/react-dom.production.min.js
You may also use a semver range or a tag instead of a fixed version number, or omit the version/tag entirely to use the latest tag.
unpkg.com/react@^16/umd/react.production.min.js
unpkg.com/react/umd/react.production.min.js
If you omit the file path (i.e. use a “bare” URL), unpkg will serve the file specified by the unpkg field in package.json, or fall back to main.
unpkg.com/d3
unpkg.com/jquery
unpkg.com/three
Append a / at the end of a URL to view a listing of all the files in a package.
unpkg.com/react/
unpkg.com/lodash/
Query Parameters
?meta
Return metadata about any file in a package as JSON (e.g. /any/file?meta)
?module
Expands all “bare” import specifiers in JavaScript modules to unpkg URLs. This feature is very experimental
Workflow
For npm package authors, unpkg relieves the burden of publishing your code to a CDN in addition to the npm registry. All you need to do is include your UMD build in your npm package (not your repo, that’s different!).
You can do this easily using the following setup:
- Add the umd (or dist) directory to your .gitignore file
- Add the umd directory to your files array in package.json
- Use a build script to generate your UMD build in the umd directory when you publish
That’s it! Now when you npm publish you’ll have a version available on unpkg as well.
