![]() ![]() Forcing consumers to introduce another package management tool just to get a few files seems heavy. We cannot guarantee that all consumers of the design system work in the npm ecosystem, though: our Data Science teams need to leverage design system CSS to build uptake branded reports and components, but they work primarily with python and the pip ecosystem. We distribute the design system via npm as a node_module. The design system is built as a set of CSS classes and html templates (ala bootstrap), and give your site an uptake look-and-feel. I work on a team that supports Uptake’s design system. This also lets you explore which other versions of the package are currently published.įinally, while unpkg’s documentation notes that assets are browser-cached for 4 hours, I found that assets were actually cached for 1 year (via cache-control headers).Just navigating to // <– note the slash at the end of the URL. You can specify a semantic version in your unpkg url, including semantic version ranges and qualifiers like ^ and ~ which will source the maximum satisfying sources the latest minor version of react 16 (16.5.2 as of this sources the latest patch version of react 16.4 (which is 16.4.2) This is a pretty amazing service to offer for free. Unpkg partners with cloudfare and heroku to make this automatic distributing possible. Unpkg is a free content delivery network (CDN) that automatically distributes public packages published to npm. The unpkg CDN is powered by Cloudflare, one of the world's largest and fastest cloud network platforms.Unpkg: the free CDN for your npm packages Instead, please reach out to with any questions or concerns. Please do not contact npm for help with unpkg. unpkg is not affiliated with or supported by npm, Inc. Unpkg is an open source project built and maintained by Michael Jackson. That's it! Now when you npm publish you'll have a version available on unpkg as well. Use a build script to generate your UMD build in the umd directory when you publish.Add the umd directory to your files array in package.json.Add the umd (or dist) directory to your.You can do this easily using the following setup: All you need to do is include your UMD build in your npm package (not your repo, that's different!). Workflowįor npm package authors, unpkg relieves the burden of publishing your code to a CDN in addition to the npm registry. This will also load more quickly because we won't have to resolve the latest version and redirect them. ![]() If you want users to be able to use the latest version when you cut a new release, the best policy is to put the version number in the URL directly in your installation instructions. Redirects are cached for 10 minutes at the CDN, 1 minute in browsers. This is the latest version when no version is specified, or the maxSatisfying version when a semver version is given. URLs that do not specify a package version number redirect to one that does. This works because npm does not allow package authors to overwrite a package that has already been published with a different one at the same version number.īrowsers are instructed (via the Cache-Control header) to cache assets indefinitely (1 year). The CDN caches files based on their permanent URL, which includes the npm package version. This feature is very experimental Cache Behavior any/file?meta) ?module Expands all “bare” import specifiers in JavaScript modules to unpkg URLs. Query Parameters ?meta Return metadata about any file in a package as JSON (e.g. use a “bare” URL), unpkg will serve the file specified by the unpkg field in package.json, or fall back to main.Īppend a / at the end of a URL to view a listing of all the files in a package. 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. ![]()
