Is there a way to check update for particular npm package using rss/atom or other similar way?

Question

I found only this thread when an user ask similar question but without answer. ( https://github.com/npm/npm-registry-couchapp/issues/17 )

I know two sites that are repositories of NPM packages:

• https://www.npmjs.com
• http://libraries.io

And I can't find a way to obtain an rss for single package in a way like it is done for github or sourceforge:

• https://github.com/<author_name>/<package_name>/releases.atom
• http://sourceforge.net/projects/<project_name>/rss?limit=20

And yes, i know that I might check what is the github repository for given NPM and do it that way, but I specifically ask for a way to reach this info from some kind of NMP repository that tracks if a given package changed its git address (not necessarily these two I added here as example.)

It is hard to find these tricks by google because it thinks I'm searching for some kind of NPM package that deals with RSS/ATOM.

Answer 1

I've recently added a release atom feed to all packages on libraries.io, simply add /versions.atom to the end of any project page url, for example:

https://libraries.io/npm/node-sass/versions.atom

With npm modules it should never be more than 10 minutes delayed in showing the newest version.

You need to hit your requests against an NPM registry, i.e. https://registry.npmjs.org/-/rss.

For single packages, the URL should be https://registry.npmjs.org/-/rss/browserfiy, but the responses aren't being constructed correctly at the time of writing.

Alternatively, you could go for a JSON response, i.e. https://registry.npmjs.org/browserify. For a more programmatic way of accessing package details, you can use npm-registry-client.
