Backend: PushSubscription model/migration, VAPID config + `cli.py generate-vapid-keys`, push_service.send_push_to_user (upsert-by-endpoint subscribe/unsubscribe, auto-cleanup of expired 404/410 subscriptions), /api/push/* router, and ConnectionManager now tracks connected user IDs per room so chat.py can push only to offline members after broadcasting to online ones. Two test-infra bugs found and fixed along the way: send_push_to_user takes the caller's AsyncSession and is awaited inline rather than fired via asyncio.create_task with its own session (background tasks were outliving the test event loop); and the ws_client fixture now uses NullPool to eliminate a connection-pool checkout race that was failing WS tests intermittently. Frontend: service worker rebuilt with vite-plugin-pwa's injectManifest strategy (custom src/sw.ts) so it can add push/notificationclick handlers alongside the existing precaching and StaleWhileRevalidate routes ported over from generateSW. New subscribe/unsubscribe flow (lib/push.ts, api/push.ts) with a toggle in the account menu. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
KeepItTalking
A web-based team chat service (Mattermost-style, no threaded conversations), invite-only. See ARCHITECTURE.md for the full system design and phased build plan.
Phase 1: auth, open-room CRUD, and single-instance WebSocket chat, backend
- a minimal frontend. Phase 2: private rooms, room roles (owner/admin/ member), and room invites — backend only, see below. Later phases (push notifications, Redis fan-out, the admin portal, the bot/extension system, and production deployment) are tracked as issues in the repo's issue tracker, prioritized.
Structure
backend/— FastAPI + SQLAlchemy 2.0 (async) + PostgreSQL. Seebackend/README.mdfor local setup, migrations, how to create a user (site registration is invite-only — no public sign-up endpoint), and the Phase 2 room-roles/invites API.frontend/— React + Vite PWA (login, room list, chat view). Still Phase-1-only: it doesn't yet call any of the Phase 2 endpoints. A UI redesign is happening separately; frontend work resumes once that lands.
Quickstart
# 1. Postgres (see backend/README.md for details)
docker run -d --name chatapp-postgres \
-e POSTGRES_USER=chatapp -e POSTGRES_PASSWORD=chatapp -e POSTGRES_DB=chatapp \
-p 5432:5432 postgres:16-alpine
# 2. Backend
cd backend
python3 -m venv .venv
.venv/bin/pip install -e ".[dev]"
cp .env.example .env # then set SESSION_SECRET
.venv/bin/alembic upgrade head
.venv/bin/python -m app.cli create-user alice alice@example.com "some-password"
.venv/bin/uvicorn app.main:app --reload &
# 3. Frontend (in another shell)
cd frontend
npm install
npm run dev
Then open http://localhost:5173 and log in with the account created above.
The Vite dev server proxies /api and /ws to the backend on :8000, so no
CORS configuration is needed in development.
Deployment
Not part of Phase 1. The target is two plain Linux servers with no containers — see ARCHITECTURE.md §9 and the corresponding "Production deployment" issue in the tracker.
