metrics

Package to retrieve, analyze, and show OWD-relevant metrics.

Set up & usage

You can fetch and store raw GitHub API data:

npm run fetch-prs <repo> to get all PRs of a repo.
- Example: npm run fetch-prs mdn/content
npm run fetch-reviews <repo> <year> to get all reviews (excluding comment reviews) in the given year
- Example: npm run fetch-reviews mdn/content 2023

Note

Fetching data from the GitHub API requires a GitHub Personal access token. Generate your token and put it in the .env file (rename the .env-dist file).

Available metrics

You can gather the following metrics:

npm run metric-merged-prs <repo> <year> to show the number of merged PRs per PR author for a repository. The year filter is optional.
npm run metric-reviewers <repo> <year> <cohort> to show the number reviews for a repository. The year filter is optional. The cohort filter is optional and can be used to only take into account reviews performed on PRs authored by non-maintainers ("community PRs").

Working with large file storage (Git LFS)

Files in the raw-data folder use Git LFS. Make sure to install Git LFS.

Once installed, you can mark files for Git LFS:

git lfs track raw-data/new-data-source.json

Now you can commit the file as usual and GitHub will upload it to a large file storage.

git add raw-data/new-data-source.json
git commit -m "Adding new LFS data source"
git push 
> Uploading LFS objects: 100% (1/1), 409 MB | 1.3 MB/s, done.

The files marked for Git LFS should appear in the .gitattributes file and you should commit changes to this file, too.
