Measurements of quality for packages, initially for npm.
To show the quality of your npm package, just add one of these images to your GitHub README:
[![Package quality]()]()[![Package quality]()]()
Or, in HTML markup:
<a href=""><img src=""/></a><a href=""><img src=""/></a>
yourpackage with (surprise!) the name of your package.
You can choose between badge or mini-badge; the latter is courtesy of shields.io.
Any objective measurements of quality are going to be flawed one way or another.
package-quality only attempts to give some indications about quality,
not be an absolute rating on which to bet your farm.
If you don't agree with our ratings, please help us improve them!
The following factors are considered when calculating the quality of a package:
r=0. For those packages with a repo on Github, r is calculated considering these three factors:
ro=1. For those with more than 20%,
rlo=1-long_open_issues/total_number_of_issues. If a package has no open issues, then
The repo quality r is calculated as the average of rt, ro and rlo:
The overall quality of a package is
Right now the quality is computed only for npm packages. But it is trivial to extend the ratings to other package managers, since there are only external measurements from GitHub and npm: we don't even look at the code.
If you want to extend package-quality to a new package manager, you just need:
Let us know and we will set up a new subdomain.
