Full-stack feature showing programming languages by commit activity
as a stream graph on the dashboard.
Backend:
- migration: repo_languages table (source, repo, language, bytes, color)
- worker: fetch language breakdowns via GitHub GraphQL (batched,
20 repos/request) and Gitea REST API during poll cycles
- API: GET /v1/languages/daily (daily commit counts per language),
GET /v1/languages/repos (all stored repo language data)
- fix timezone bug in daily_counts and language_daily_counts: the
PostgreSQL server timezone (Europe/Sofia, UTC+3) shifted day
boundaries, miscounting events near midnight. Now uses explicit
UTC boundaries in generate_series JOINs.
- use per-source CASE for repo name extraction in language query
to match gitea payload structure (repo.full_name vs repo.name)
- Gitea languages use GitHub colors via COALESCE fallback
Frontend:
- LanguageStreamGraph component: pure SVG stream graph, weekly
buckets, centered baseline, top 8 languages + Other, GitHub
canonical language colors, legend with color dots
- DashPage/ProjectPage: fetch repo languages once via new endpoint
instead of per-repo forge proxy calls (eliminates 200+ GitHub
API calls and 403 rate limit errors)
- removed fetchLanguages forge proxy wrapper (dead code)

The DB now stores everything GitHub will give us, the API only ever
returns public events (for now).
Endpoint switch in the github poller: when GITHUB_TOKEN is set we
hit /users/{u}/events (public + private), otherwise fall back to
/users/{u}/events/public. Either way each event's top-level `public`
boolean is captured into a new column.
Schema:
migration 0003_event_public.sql adds events.public BOOLEAN NOT NULL
DEFAULT true, plus an index on (public, occurred_at DESC).
Wire:
Event gains a `public: bool` field.
EventQuery gains `include_private: bool` (default false).
list_events and source_summaries gate on it.
moments-api pins include_private = false at every call site —
threading it as a query param is a future-auth concern, not now.
The default-true on the column keeps existing rows correct: the 11
events already in the DB came from /events/public and are genuinely
public.
After this change, clear poller_state so the next worker run does a
fresh backfill via /events:
DELETE FROM poller_state WHERE source = 'github';
Tests: +2 in github poller (private flag captured, default-public
on missing field) — 10 total green.

Adds the first ingestion source. Page-1 polling is ETag-conditional
(304s don't count against rate limit); the very first run paginates
back through Link "next" pages up to a 10-page safety cap so the
table starts populated rather than waiting for new activity.
Hits /users/{user}/events/public — works without auth, returns the
right scope for a public timeline. Token (GITHUB_TOKEN) is optional;
when present it raises the rate limit from 60 to 5000/hr.
New plumbing:
moments-core::sources
- EventSource trait (poll() -> count)
- PollerStateStore trait (etag persistence port)
- run_poller driver: tokio interval + jittered exponential backoff
moments-data::github
- GithubSource impl, raw payload preserved as JSONB
- parse_link_next for pagination
- 4 unit tests covering parser + Link parsing
migration 0002_poller_state.sql
- one row per source: source, etag, last_modified, last_fetched
Worker binary spawns one tokio task per source (just github for now)
and aborts on SIGINT. Verified by smoke-curling the upstream endpoint:
ETag and Link headers are present; payload shape matches the parser.
