# Frontend Engineering (Canonical) **Expertise: expert.** Aliases: `frontend`, `spa`, `react-ui` (framework-agnostic patterns; runtime tooling via `nodejs` / `nodejs-devtools`). ## When to use - Halaman/komponen, routing, state, form, tabel, modal - Integrasi API (loading/empty/error), pagination UI - Accessibility dasar + performa render ## When not to use - Hanya kontrak API → `api-engineering` - Browser E2E automation → `browser-automation` ## Procedure 1. **Theme lock** — Ikuti tema/UI existing project; jangan mengganti arah visual diam-diam. 2. **One job per view** — Satu tujuan jelas; hormati design system / UI rule project. 2. **States** — Loading, empty, error, success selalu ditangani. 3. **Data** — Fetch sesuai kontrak; jangan asumsikan shape array jika envelope `items/meta`. 4. **A11y** — Label, fokus keyboard, kontras; modal trap fokus & restore. 5. **Performance** — Hindari re-render berat; list besar paginated; lazy route/assets bila perlu. 6. **Security** — Jangan simpan secret di bundle; sanitize URL/HTML berbahaya. 7. **Verify** — Manual atau `browser-automation`; responsive smoke. Detail: `reference.md`. ## DoD - [ ] States lengkap; a11y dasar OK - [ ] Selaras kontrak API + pagination - [ ] Modal tidak merusak layout/performa - [ ] Tidak ada dead UI / handler kosong - [ ] Evidence smoke atau blocker
