Add rate limiting, production server hardening, and CD workflow#20pascaljoly wants to merge 1 commit into
Conversation
Closes Ribbit-Network#17: per-API-key token-bucket rate limiter (60 req/s, burst 30) in new internal/ratelimit package, wired into /data after auth. Closes Ribbit-Network#15: http.Server with read/write/idle timeouts, graceful SIGTERM shutdown, /healthz endpoint, CORS middleware, and a fly.io CD workflow (.github/workflows/deploy.yml) that deploys on push to main. Issue Ribbit-Network#14 (API keys) was already implemented in the codebase. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Hey @pascaljoly! Thanks for the new changeset! I see the CI is failing due to a license key issue. I thought I had sorted that out for the secret monitoring, but let me fix it again. |

Ok this is a good start, but there are a few changes I think we need to make before we merge this. Let me know if you have bandwidth to do so, but if not I can knock them out @pascaljoly

The comment here and the burst limit in the code below disagree. The comment says burst 30, but the code below is burst 60.

The actual rate limited never removes a client when added, which will be an infinite memory leak. We should eventually remove clients after some time threshold or use a library like https://github.com/didip/tollbooth which handles the removal.

This function appears to be a duplicate of the one in middleware.go

We should probably use the authentication layer. The auth should then stash the verified key in r.Context() and let ratelimit read it from there.

This deploys no matter what, even if the tests fail etc. Either needs: the CI job or run go test ./... before flyctl deploy
