Replaces the hardcoded version string in SettingsPage.tsx with a single
source of truth: a /VERSION file at the repo root. To cut a new release,
edit only that one file.
Frontend:
- vite.config.ts reads /VERSION at dev-server startup and injects it as
the __APP_VERSION__ global via Vite's define mechanism (compile-time,
zero runtime cost). Falls back to VITE_APP_VERSION env var for prod
Docker builds that pass it as a build arg.
- vite-env.d.ts adds the TypeScript declaration for __APP_VERSION__.
- SettingsPage.tsx Badge now renders {__APP_VERSION__} instead of the
literal string.
Backend:
- app.controller.ts reads /VERSION once at module load and includes
"version" in both GET /api and GET /api/health responses.
- NewRelicTransactionInterceptor tags every NR transaction with
newrelic.addCustomAttribute('appVersion', version) so releases can be
compared in NRQL: SELECT average(duration) FROM Transaction WHERE
appVersion = '2026.5.22'
Docker:
- docker-compose.yml mounts ./VERSION:/app/VERSION:ro in both backend
and frontend dev containers.
- Production Dockerfiles include COPY VERSION ./ with a comment
instructing CI to copy the root VERSION into each build context before
docker build.

Add Node.js New Relic agent with an on/off switch via NEW_RELIC_ENABLED
in .env. Uses a preload script (-r newrelic-preload.js) so the agent
loads before all other modules. Configured entirely through environment
variables — no newrelic.js config file needed.

Root cause of 502 errors under 30 concurrent users: the production server
was running dev-mode infrastructure (Vite dev server, NestJS --watch,
no DB connection pooling, single Node.js process).
Changes:
- backend/Dockerfile: multi-stage prod build (compiled JS, no devDeps)
- frontend/Dockerfile: multi-stage prod build (static assets served by nginx)
- frontend/nginx.conf: SPA routing config for frontend container
- docker-compose.prod.yml: production overlay with tuned Postgres, memory
limits, health checks, restart policies
- nginx/production.conf: keepalive upstreams, proxy buffering, rate limiting
- backend/src/main.ts: Node.js clustering (1 worker per CPU, up to 4),
conditional request logging, production CORS
- backend/src/app.module.ts: TypeORM connection pool (max 30, min 5)
- docs/DEPLOYMENT.md: new Production Deployment section
Deploy with: docker compose -f docker-compose.yml -f docker-compose.prod.yml up -d --build
