React StrictMode double-invokes the effect that opens the chat WebSocket in dev (mount -> cleanup -> mount again, on purpose, to catch exactly this class of bug). The first socket gets abandoned in cleanup, but its onclose still fires asynchronously afterward -- and unconditionally ran `socketRef.current = null`, even after the second (real) socket had already taken over. That silently orphaned a perfectly live connection: still open and receiving broadcasts fine, but nothing left holding a reference to send on, so outgoing messages/edits went nowhere with no visible error. Found via manual testing: messages sent through the UI weren't appearing, but a raw WebSocket opened by hand (bypassing React entirely) joined and sent a message successfully, isolating the bug to the reconnect logic rather than the backend. Fix: each socket's onopen/onclose now checks it's still the one referenced by socketRef before mutating shared state, so a stale/superseded socket's events are inert instead of clobbering whatever socket is actually current.

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
See DEPLOYMENT.md for the full production runbook — two Debian 13 servers, no containers, matching ARCHITECTURE.md §9.
