Skriptoteket Frontend Specialist

Defaults

• SPA-only: do not re-introduce template/HTMX UI (ADR-0027 clean-break cutover).
• Use Vue 3.5 Composition API with <script setup lang="ts">.
• Keep the frontend HuleEdu-aligned so it can be integrated into HuleEdu later (shared design tokens and compatible auth model).
• Keep integration costs low: avoid hardcoded base paths, isolate auth transport (cookie vs bearer), and prefer token-driven styling over bespoke CSS.
• Styling is tokens-first: tokens.css (canonical --huleedu-*) + tailwind-theme.css (Tailwind bridge via @theme inline).
• Single CSS entry point: frontend/apps/skriptoteket/src/assets/main.css (imports Tailwind + tokens + theme once).
• Use SPA primitives from frontend/apps/skriptoteket/src/assets/main.css to avoid drift:
  • Buttons: .btn-primary, .btn-cta, .btn-ghost
  • Panels (nested): .panel-inset, .panel-inset-canvas
  • Toasts: .toast-* (via ToastHost)
  • Inline messages: .system-message* (via SystemMessage)
  • Badges: .status-pill
• No stacked brutal shadows: only the outermost “card/panel” gets shadow-brutal*. Nested panels/fields inside a shadowed surface use shadow-none + thicker, uniform borders (panel-inset*, or border-2 border-navy/20).
• No Tailwind default palette leakage in product UI: avoid bg-slate-*, text-gray-*, etc. Prefer token-mapped utilities (bg-canvas, text-navy, shadow-brutal-sm) or CSS variables.
• Page/editor transitions: prefer opacity-only transitions (hard borders/shadows shimmer when translated).
• Admin editor features: extract logic into frontend/apps/skriptoteket/src/composables/editor/ and keep views UI-only.

Repo map (Skriptoteket monolith)

• Backend (FastAPI + SPA hosting + APIs): src/skriptoteket/web/
  • Static assets: src/skriptoteket/web/static/ (/static/*)
  • Built SPA assets: src/skriptoteket/web/static/spa/ (served via history fallback)
• Frontend workspace (pnpm): frontend/
  • SPA app: frontend/apps/skriptoteket/
  • (Legacy) islands: frontend/islands/

Workflow

1. Work from the repo root:
   • Backend dev: pdm run dev (or pdm run dev-logs for log piping)
   • Frontend install: pdm run fe-install
   • SPA dev server: pdm run fe-dev (or pdm run fe-dev-logs for log piping)
   • Local combo (backend + SPA): pdm run dev-local
   • Container dev: pdm run dev-start (logs: pdm run dev-containers-logs, rebuild: pdm run dev-rebuild)
   • SPA tests: pdm run fe-test (Vitest), pdm run fe-type-check, pdm run fe-lint
2. Implement in this order:
   • OpenAPI models (backend) -> regenerate TypeScript types (pdm run fe-gen-api-types)
   • API client calls in SPA
   • Pinia stores for shared state, views/components for UI
3. Keep styling token-driven and HuleEdu-compatible (ADR-0032 + @theme inline bridge).
4. Keep auth integration "pluggable" so HuleEdu SSO can be added without rewriting the SPA (ADR-0006/ADR-0011 + current cookie/CSRF transport).

Patterns

Pinia state

• Define stores with defineStore(...); keep state/actions cohesive and typed.
• Avoid destructuring the store object; use storeToRefs(store) when you need refs.
• Centralize auth/session state in one store and let router guards depend on it.

Routing + hosting

• Use history mode routing with server-side fallback (backend serves index.html for non-API routes).
• Avoid hardcoding absolute paths; keep router base aligned with Vite base.

API contracts

• Treat OpenAPI as the source of truth and generate TypeScript types via openapi-typescript.
• Keep response/error envelopes consistent; handle 401/403 centrally.

Auth (integration-ready)

• Current Skriptoteket reality: cookie-session auth + CSRF for mutating requests.
• Future HuleEdu integration: identity federation without shared authorization (keep Skriptoteket roles local).
• In the SPA, isolate auth transport details behind a small adapter (cookie vs bearer) so the UI can run in both modes.

Layout + editor ergonomics

• Full-height editor routes:
  • Wrap route content in route-stage + route-stage-item (see frontend/apps/skriptoteket/src/App.vue).
  • Use route-stage--editor for editor routes so nested flex/grid children can use min-h-0.
  • In authenticated layout, use the editor variant (auth-main-content--editor) to avoid double scrollbars and let the editor manage its own scroll regions (see frontend/apps/skriptoteket/src/components/layout/AuthLayout.vue).
• Focus mode (width matters):
  • Persisted per user via useLayoutStore (frontend/apps/skriptoteket/src/stores/layout.ts).
  • Editor is the primary entry point for toggling; ensure the user is never “trapped” without an exit control.
• Drawers:
  • Reuse the existing right-side drawer surface for editor chat/history; don’t introduce a second sidebar.
  • Prefer bg-canvas + border-navy + shadow-brutal-sm for drawer frames (see EditorWorkspacePanel.vue).
• Dense toolbars:
  • Use the editor micro-typography pattern: text-[10px] font-semibold uppercase tracking-wide text-navy/60.
  • Use .btn-ghost with size/shadow overrides for 28px controls (see EditorWorkspaceToolbar.vue).

Testing (Vitest)

• Config: frontend/apps/skriptoteket/vitest.config.ts
• Setup: frontend/apps/skriptoteket/src/test/setup.ts
• Tests: frontend/apps/skriptoteket/src/**/*.spec.ts (colocate with code)
• Commands: pdm run fe-test / pdm run fe-test-watch / pdm run fe-test-coverage
• Prefer testing pure helpers/composables and mocking HTTP via vi.mock rather than snapshot-heavy component tests.

HuleEdu compatibility checklist

• Versions: Vue 3.5.x / Pinia 3.x / Vue Router 4.6.x / Vite 6.x (match HuleEdu minor lines).
• Paths: use import.meta.env.BASE_URL + relative URLs so the SPA can be hosted under a subpath.
• Auth: handle 401 centrally; do not assume a separate Skriptoteket login UI exists in "integrated" mode.
• Styling: use HuleEdu tokens as the contract; avoid hard-coded colors/fonts.
