Replace the hybrid flow (frontend PKCE + POST /auth/session token exchange, access token in sessionStorage) with a classic backend-driven BFF: the browser only ever navigates to GET /api/v1/auth/login and is redirected straight to the IdP; PKCE verifier/state live server-side in Redis (SessionStoreService); GET /api/v1/auth/callback (now the registered IdP redirect URI, replacing the frontend's /auth/callback route, which is deleted) verifies the id_token, JIT-provisions the user, creates a Redis-backed session, and sets one httpOnly SameSite=Lax cookie before redirecting into the app. No token material of any kind ever reaches the browser. OidcAuthGuard (per-request bearer JWT verification) is replaced by SessionAuthGuard (cookie -> Redis session lookup) across every controller that used it. cookie-parser is now wired into main.ts. Frontend AuthService shrinks to login()/logout()/ensureSessionChecked(); pkce.ts, auth.interceptor.ts, and the callback component/route are all removed as dead code under this model. New required env var: APP_BASE_URL (source of truth for the OIDC redirect_uri and the post-login redirect target). Verified end-to-end against the real API, Redis, and a mocked IdP: login redirect shape, callback cookie + redirect, state-replay rejection, /users/me 401<->200 around the cookie, and logout.
Frontend
This project was generated using Angular CLI version 21.2.6.
Development server
To start a local development server, run:
ng serve
Once the server is running, open your browser and navigate to http://localhost:4200/. The application will automatically reload whenever you modify any of the source files.
Code scaffolding
Angular CLI includes powerful code scaffolding tools. To generate a new component, run:
ng generate component component-name
For a complete list of available schematics (such as components, directives, or pipes), run:
ng generate --help
Building
To build the project run:
ng build
This will compile your project and store the build artifacts in the dist/ directory. By default, the production build optimizes your application for performance and speed.
Running unit tests
To execute unit tests with the Vitest test runner, use the following command:
ng test
Running end-to-end tests
For end-to-end (e2e) testing, run:
ng e2e
Angular CLI does not come with an end-to-end testing framework by default. You can choose one that suits your needs.
