From 14718bdeac226fb5ebd51f85778b1f21995dff35 Mon Sep 17 00:00:00 2001 From: prosdev Date: Sun, 11 Jan 2026 10:36:29 -0800 Subject: [PATCH 1/3] feat(api): add HTTP collection API with health checks and CI support Implemented: - Core /collect and /collect/{stream} endpoints - Convenience endpoints: /v1/identify, /v1/track, /v1/page - Health checks: /health (liveness), /ready (readiness with Firestore check) - Dependency injection (get_queue, get_event_store, get_settings) - FastAPI app with lifespan manager (start/stop queue) - Always return 202 Accepted (no rejections at edge) Components: - src/eventkit/api/ - FastAPI application with router, dependencies, and app - src/eventkit/stores/ - Added health_check() protocol and implementation - src/eventkit/config.py - Removed unused FIRESTORE_*_COLLECTION settings Tests: - 14 new tests for API endpoints (150 total passing) - 94% code coverage - Mock-based unit tests for API layer - Tests for both healthy and unhealthy states CI: - Updated GitHub Actions to use docker-compose (consistent with local dev) - Firestore emulator with healthchecks via --wait flag - All tests (unit + integration) run in CI Documentation: - LOCAL_DEV.md - Comprehensive local development guide - README.md - Streamlined setup with link to LOCAL_DEV.md - CLAUDE.md - Updated with latest patterns (queue-agnostic processor, API patterns, Docker Compose workflow) --- .github/workflows/test.yml | 10 ++ CLAUDE.md | 122 +++++++++++++++--- LOCAL_DEV.md | 93 ++++++++++++++ README.md | 36 ++---- src/eventkit/api/__init__.py | 6 + src/eventkit/api/app.py | 77 ++++++++++++ src/eventkit/api/dependencies.py | 101 +++++++++++++++ src/eventkit/api/router.py | 145 ++++++++++++++++++++++ src/eventkit/config.py | 7 +- src/eventkit/stores/event_store.py | 12 ++ src/eventkit/stores/firestore.py | 18 +++ tests/unit/api/__init__.py | 1 + tests/unit/api/test_router.py | 190 +++++++++++++++++++++++++++++ 13 files changed, 772 insertions(+), 46 deletions(-) create mode 100644 LOCAL_DEV.md create mode 100644 src/eventkit/api/__init__.py create mode 100644 src/eventkit/api/app.py create mode 100644 src/eventkit/api/dependencies.py create mode 100644 src/eventkit/api/router.py create mode 100644 tests/unit/api/__init__.py create mode 100644 tests/unit/api/test_router.py diff --git a/.github/workflows/test.yml b/.github/workflows/test.yml index f48bce6..8e98a6a 100644 --- a/.github/workflows/test.yml +++ b/.github/workflows/test.yml @@ -22,6 +22,9 @@ jobs: with: python-version: "3.12" + -
