Prepares the data for the leaderboard on nuxt.com/nuxters: one leaderboard per period, the date of each contributor's first contribution, and a bonus for the framework repository.

Output

public/ now has one file per period, all with the same record format:

  • contributors.json: all time (as today, plus the new fields)
  • contributors-30d.json and contributors-12m.json: rolling windows at collection time
  • contributors-<year>.json: one per year from 2016 (UTC)

The collector reads each repository once, as before. Each item counts in "all time", its year, and the windows it falls in. Merged PRs count on merged_at; issues and comments count on created_at. Reactions count on the date of the item that received them, because exact reaction dates would need one API call per item.

New fields in each record:

  • first_contribution_at: the earliest issue, comment or merged PR.
  • core: the merged PRs, helpful issues and helpful comments made in nuxt/nuxt, nuxt/framework and nuxt/docs. The totals already include them.

Score

Merged PRs, helpful issues and helpful comments in the core repositories count double: score = base + qualityPoints(core) × (CORE_MULTIPLIER - 1). Raw issues, comments and reactions do not double.

nuxt/framework (Nuxt 3, 2,742 merged PRs) and nuxt/docs (1,670 merged PRs) are archived, so the collector skipped them until now. They are collected again through INCLUDE_ARCHIVED.

Other changes

  • The files have one record per line instead of 2-space indentation. They stay valid JSON with readable diffs. With the new fields, the all-time file grows about 20%; it would grow about 85% with indentation.
  • The workflow commits public/contributors*.json and detects new files (the first file of a new year).
  • COLLECT_REPOS and CONTRIBUTORS_OUTPUT_DIR let you run a quick local test without touching public/. The README describes them.

Effects after merge

  • Every score goes up and some ranks change, on nuxters.nuxt.com too.
  • The score modal of nuxters.nuxt.com does not know the bonus, so its rows will no longer add up to the score. The nuxt.com version shows the bonus rows.
  • The nightly run reads two more repositories, so it takes a bit longer.

Tests

  • pnpm lint, pnpm test:unit and a strict tsc on the script pass.
  • Collector runs with a real token on nuxt/docs + nuxt/nuxters (984 contributors) and on nuxt/nuxters + nuxt/test-utils (702 contributors). For every contributor, each score matches an independent calculation. Core counts never exceed the totals. The yearly numbers add up to the all-time numbers.
  • The archived-repo filter, applied to the 20 archived repos of the nuxt org, keeps exactly nuxt/framework and nuxt/docs.
  • I did not run a full collection (about an hour).

📝 Walkthrough

Walkthrough

The collector now tracks contributors in all-time, rolling-window, and calendar-year periods. It uses contribution dates to assign issues, comments, and merged pull requests to periods, records earliest contribution dates, and applies additional quality points for activity in core repositories. It can collect selected repositories and write period-specific JSON files. The workflow detects and stages changed contributor JSON files matching the expanded filename pattern.

Prevent partial collections from being written.

collectOrganization catches errors and continues. If one organization fails after other data was collected, contributors.json can exceed the 1000-byte check while the period maps remain incomplete. The collector then writes every period file, and the workflow stages them all.

Track collection failures and stop before writing any output. Do not apply the all-time byte threshold to period files because empty periods are valid.
