## Summary First user-visible piece of the auth track. The portal-shell SPA now consumes the BFF auth surface (`/api/auth/me`, `/api/auth/login`, `/api/auth/logout`) and the header reflects sign-in state. - `libs/feature/auth` ships an `AuthService` that fetches `/auth/me` on first injection, holds a signal-backed `AuthState` (`loading` / `anonymous` / `authenticated` / `error`) and exposes `currentUser` + `isLoading` computed signals plus `login()` / `logout()` / `refresh()` methods. - The header's right-side widget renders four states: a sign-in button when anonymous, the user avatar (initials, `JD` for "Jane Doe") + display name + sign-out button when authenticated, a loading dot before `/me` resolves, and a "Can't reach the server" chip on non-401 failures. - `login()` / `logout()` go through an injected `AUTH_NAVIGATOR` token whose default calls `window.location.assign(url)`. Specs override it with `vi.fn()` — no `window.location` mocking required. ## Notable choices **Auto-bootstrap on construction, not via `provideAppInitializer`.** The service fires `/me` from its constructor (unawaited) so consuming components transition through the explicit `loading` state. Blocking app boot on the round-trip would push the first paint behind the network call — bad for TTFB, especially on slow links. The header handles `loading` as a first-class state. **Discriminated `AuthState` over flat fields.** A single source of truth (`state()`) with four `kind`s lets templates `switch` and narrow automatically. `currentUser` and `isLoading` are computed conveniences but never out of sync with `state`. **`AUTH_BFF_BASE_URL` + `AUTH_NAVIGATOR` injection tokens.** Decouples the lib from the host's `environment.ts` shape and keeps tests free of `window.location` redefinition (which jsdom resists across multiple specs in the same file — first redefine works, second throws "Cannot redefine property"). The host wires both in `app.config.ts`. **Curated public user type.** `CurrentUser` mirrors the BFF's `/me` response (`oid`, `tid`, `username`, `displayName`) — no `amr`, no internal claims. The shape lives in `auth.types.ts` so feature code can import it without depending on Angular HTTP details. **Distinct `error` state.** A network failure / 5xx surfaces a different UI than "not signed in" — "Can't reach the server" chip vs. sign-in button. Avoids the trap of treating any `/me` failure as "anonymous". ## Out of scope (next PRs) - Route guards (protecting routes from anonymous users). For now the header is the only consumer. - Auto-refresh of the session before idle timeout. - HTTP interceptor that redirects to `/auth/login` on a 401 from any other BFF call. - Per-locale styling polish on the new header strings. ## Test plan - [x] `pnpm nx test feature-auth` → **8/8 pass**. - [x] `pnpm nx test portal-shell` → **32/32 pass** (was 27 before). - [x] `pnpm nx lint portal-shell feature-auth` → clean. - [x] `pnpm nx build portal-shell` → main bundle 488 kB raw / 129.94 kB transfer; well under the 300 kB gzip budget from ADR-0017. - [ ] Manual smoke once the BFF is up: - [ ] Anonymous landing → header shows "Sign in". - [ ] Click "Sign in" → BFF /login → Entra → callback → SPA lands with avatar + display name in the header. - [ ] Click "Sign out" → BFF /logout → Entra logout → back at SPA, header back to "Sign in". --------- Co-authored-by: Julien Gautier <julien.gautier@apf.asso.fr> Reviewed-on: #113
Documentation index
This is the entry point to all project documentation. It is maintained automatically: any addition, rename, or removal of a .md file under docs/ must be reflected here in the same change.
Conventions
- Documentation is written in English.
- One topic per file. Group related files into a folder when there are three or more.
- Cross-reference with relative links so they keep working in GitHub, IDEs, and exported sites.
- For architectural decisions, do not add them here — they belong in decisions/ as MADR 4.0.0 ADRs.
Sections
Daily development
- development.md — repo layout, prerequisites, initial setup, daily commands, observability dev-loop (Jaeger UI, log ↔ trace correlation), dependency updates (Renovate), conventional commit cycle. Day-to-day reference for working on the project.
Architecture
- architecture.md — cross-cutting Mermaid diagrams: C4 system context, C4 containers, Nx module boundaries, CI/CD pipeline. Single-decision diagrams (auth sequence, ERD, etc.) live inline in their ADR.
