Production image for the frontend dist. Stage 1 (build): node:22-alpine, `npm ci --ignore-scripts` from the committed lockfile, `npm run build`. Output lands in /app/dist. Stage 2 (runtime): docker.io/nginxinc/nginx-unprivileged:alpine. - Upstream-maintained variant that runs as the nginx user (uid 101) out of the box. /var/cache/nginx and /var/run/nginx are pre-owned, no chown gymnastics needed in our layer. Vanilla nginx:alpine fails at startup as non-root because client_temp mkdir is denied. - Listens on 8080 (non-privileged port, matches the unprivileged variant convention). - nginx.conf serves /usr/share/nginx/html with SPA `try_files` fallback for client-side routing, long-cache headers on /assets/ (Vite hashed bundles), a plaintext /healthz endpoint for Caddy / Prometheus blackbox, and server_tokens off. .dockerignore excludes node_modules, dist, .vite, coverage, playwright-report, .env*, .git, editor dirs. Keeps .env.example. Smoke local validated with `podman build -t mimic-frontend:smoke .` and `podman run -p 127.0.0.1:18080:8080`: /healthz -> 200 "ok" / -> 200 index.html (508 B) /spa/x -> 200 (SPA fallback) /assets -> Cache-Control: max-age=31536000, public, immutable
Mimic frontend
React + TypeScript SPA for the Mimic BAS platform. Lives behind the existing RT reverse proxy (Caddy + TLS + IP allowlist) — see D-007.
Stack
- React 19, TypeScript strict
- Vite 8 (dev/build)
- Tailwind 4 (semantic tokens in
src/styles/theme.css) - TanStack Query 5 for server state
- react-router-dom v7 for routing
- Recharts for the report visualisations
- Vitest + Testing Library for unit tests
- Playwright for E2E (covered in sprint 1+)
Scripts
npm install
npm run dev # vite dev server on :5173
npm run build # tsc -b && vite build
npm run typecheck # tsc -b --noEmit
npm run lint # eslint . (strict TS + react-hooks + prettier)
npm run format # prettier --write .
npm test # vitest run
npm run e2e # playwright test (needs npm run e2e:install once)

Design system status (provisional)
The token layer in src/styles/theme.css is structured to receive the RT
graphic charter (PR3) without touching component code. Component CSS reads
exclusively from semantic tokens (--accent-rt, --status-detected, …);
swapping the underlying primitive palette is the only change required when
PR3 lands.
Auth status (sprint 0)
The session context reads/writes a mock user in sessionStorage. No real
auth yet. v1 will wire local username/password + bcrypt (D-003); v2 maps
Keycloak OIDC claims onto the same role enum.
Fonts
IBM Plex (Sans / Sans Condensed / Mono), self-hosted under public/fonts/.
Files are not yet vendored — see public/fonts/README.md. Until then the
UI falls back to ui-sans-serif / ui-monospace.
