feat(api): cache GitHub star count server-side#24
Merged
Conversation
The header star badge fetched api.github.com directly from every visitor's browser, which is rate-limited to 60 req/hour per IP — heavy traffic from one IP made the count silently vanish. Add /api/github/stars, which fetches the count on the Worker and edge-caches it (cf cacheTtl 1h + Cache-Control), so GitHub is hit ~once/hour per colo regardless of traffic. Falls back to a sane default if upstream is unreachable. The badge now calls this same-origin endpoint instead of GitHub.

Summary
GitHubStarBadgefetchedapi.github.comdirectly from every visitor's browser. GitHub's unauthenticated API is capped at 60 req/hour per IP, so heavy traffic from one IP exhausts it and the star count silently disappears (the component hides the count on a failed/403response)./api/github/stars— fetches the count on the Worker and edge-caches it (cf: { cacheTtl: 3600, cacheEverything }+Cache-Control), so GitHub is hit ~once/hour per colo regardless of visitor volume. Sends aUser-Agent(GitHub rejects API calls without one). Falls back to a sane default + shorter cache if upstream is unreachable.Test plan
