work in progress

gendn

Generated reference docs for the APIs that ship in Chrome but don't yet have a page on MDN. When MDN already covers an API, gendn just links out. The goal is the gap between "shipped in Chrome" and "documented on developer.mozilla.org".

how it works

  1. A daily routine reads chromestatus.com for features shipping in Chrome (stable, beta, dev, plus prev-stable).
  2. For each, it checks MDN. If MDN has a page, gendn just links to MDN.
  3. If MDN doesn't have a page, the routine writes a reference doc generated from the spec, explainer, and the IDL in Chromium source.
  4. When MDN later ships its own page, the routine notices on the next pass and the gendn entry switches to a "see MDN" stub.
