backage

It's all part and parcel

---

Wish you could show npm, gem, mvn, Gradle, NuGet, or GHCR badges? Or just query for the download counts? Tough luck; the GitHub Packages API has never exposed publicly-available metadata that other registries provide. This is the solution: Star this project to have GitHub generate an additional endpoint for your public packages!

A service ran by GitHub will add them to its circular priority queue within the next few hours and update the closed-loop system. If you'd then like the service to forget and ignore some or all of your packages, add owner[/repo[/package]] to optout.txt here and make a pull request.

To add any other users or organizations not yet in the index, add the case-sensitive name of each one on a new line in owners.txt on your own fork here and make a pull request. Please add just the name(s) -- ids, repos, and packages will be found automatically!

Once you've confirmed that the packages you're interested in are found and their metadata update without issue, you can create an independent instance for them that'll update more frequently. This centralized repo will then serve as a backup. Simply fork just the master branch, then enable Actions from its tab and all disabled workflows. While you can update your optout.txt immediately, please wait for the Alternative URL in your fork to change to yours before adding any other users or organizations to your owners.txt.

The Endpoint

https://ipitio.github.io/backage/OWNER/[REPO/[PACKAGE]].FORMAT

Replace the parameters with their respective values, scoping to your parsing needs, then access the latest data however you want. Use something like shields.io/json or shields.io/xml to make badges like the ones above or the one here.

Note

The format can be either json or xml. You'll need the XML endpoint to evaluate expressions, like filters, with Shields -- see this issue.

Tip

Use the proxy to convert external JSON to XML! This doesn't currently work with Shields, though.

They can be queried with the following paths:

JSON

You can query a package for its properties, like size or version:

$.PROPERTY

$.size

Versions may be filtered in and tags out:

$.version[FILTER].PROPERTY

$.version[?(@.latest)].tags[?(@!="latest")]

As can packages in owner[/repo]/.json files:

$.[FILTER].PROPERTY

XML

You can query a package for its properties, like size or version:

/xml/PROPERTY

/xml/size

Versions can be filtered in and tags out:

/xml/version[FILTER]/PROPERTY

/xml/version[./latest[.="true"]]/tags[.!="latest"]

As can packages in owner[/repo]/.xml files:

/xml/package[FILTER]/PROPERTY

Alternative URL

https://github.com/ipitio/backage/raw/index/OWNER/[REPO/[PACKAGE]].FORMAT

The endpoint is also available at this URL that doesn't rely on Pages.

JSON2XML Proxy

Use your own JSON endpoint with this proxy to convert it into XML. Try it out in your browser:
