Daniel Noulet 5449cd3d8d feat: avatar, account menu, and single sign-on from Go Loose 
Signing in now starts at the sign-in screen and one button that hands the
browser to Go Loose, which returns to the welcome page. Nothing redirects to the
identity provider on its own any more: that fired on every anonymous visit and
read as a redirect loop rather than as a choice to sign in. The password form
remains only where the API reports that Go Loose login is not configured for the
host, because otherwise the application is unreachable on a bare localhost.

A person's picture is carried through from the Go Loose identity and rendered in
the account menu and on the profile page, with their initials as the fallback.
Two things make that fallback necessary rather than decorative: Go Loose retires a
picture key when a picture is replaced, so a link cached in a browser can be dead,
and most people have not uploaded one. The URL is deliberately not persisted
locally, since a stored key would keep failing after the picture changed.

The account menu is a disclosure rather than a hover menu: a real button with
aria-expanded, Escape and outside clicks closing it, and focus returning to the
trigger. It is not an ARIA menu, because its actions are a link and a button and
menuitem roles would strip the link semantics from one of them for no gain.

The account URL of the Go Loose identity is resolved on each sign-in and is read
from the live identity provider every time, which is also what makes it correct
after a picture change.

Depends on the Go Loose revision that serves avatar_url through
/connect/userinfo, so the picture URL reaches this application at all.

Go Guess frontend

React and TypeScript recruitment workspace built with Vite.

Commands

npm install
npm run dev
npm run typecheck
npm run lint
npm run format
npm run format:check
npm test
npm run build

Run one test:

npm test -- src/app/App.test.tsx -t "filters jobs by title"

Source structure

  • src/app contains the application shell, providers, routes, and route-level tests.
  • src/features groups pages and components by business capability.
  • src/components contains UI shared by multiple features.
  • src/config/navigation.ts defines configurable footer sitemap and useful-link groups.
  • src/api/client.ts is the typed HTTP boundary.
  • src/types contains API and domain types.
  • src/styles/global.css contains shared tokens and layout styles.

Keep feature-only UI close to its feature instead of adding more screens to the application shell.

API integration

For tenant hosts such as nmbs.guess-dev.urpi.be locally and nmbs.guess.urpi.be in production, src/api/client.ts derives tenant nmbs, calls same-origin /api through the shared HTTPS proxy, and sends X-Tenant-Id: nmbs on every JSON, multipart, file-download, and event-stream request. ypto.guess-dev.urpi.be behaves identically for tenant ypto. Other hostnames use same-origin /api; Vite retains its /api proxy for that case.

src/components/actions/Account.tsx treats any host whose first DNS label is a tenant as a possible Go Loose host and asks /api/auth/session whether browser login is available there. A 404 means the API has no Go Loose login for the host, so the password form is shown; any other unauthenticated answer means Go Loose is configured and the app redirects to /api/auth/login. The callback exchanges that session for the bearer token used by the typed API client. Invitation and participant-meeting URLs use the validated request origin so links stay on the tenant hostname. Copy actions fall back to a temporary selected textarea when the Clipboard API is unavailable on local HTTP domains.

Login stores the returned JWT in sessionStorage; protected requests send it as Authorization: Bearer <token>. API failures are shown in the UI and are never replaced with demo data. A 401 from a protected JSON, file, or event-stream request clears authentication and returns the user to /login. On a tenant host with Go Loose configured, the app restores /api/auth/session or redirects to /api/auth/login; participant routes stay token-based. The app also schedules logout from the JWT expiration claim so an idle expired session cannot remain on a protected page.

The machine-readable OpenAPI 3.0 contract at /api/openapi.json is the source of truth for supported routes and schemas. It is assembled by the backend from the same typed calls that register Chi routes, so there is no generated file or manual update command. Do not duplicate a route inventory here; inspect the contract instead.

Participant creation uses multipart fields firstName, lastName, birthday, email, contactInfo, photo, and cv.

Interview workflow

Authenticated interviewers create and edit reusable questions at /questions, configure job status and duration, attach active library questions, and generate invitations for each eligible participant from a job detail page. Multiple-choice and radio questions require at least two explicitly added options. Detaching a question removes only the job association; questions can be deprecated but not deleted. Open-answer and code-review questions include an interviewer-only reference answer that is never rendered in the participant interview. Code-review questions also require a code snippet. Accepted and completed invitations can be opened from the job to review every participant answer, possible choice options, reference answers, and code-review context; unanswered questions are called out explicitly. Completed assessments can be marked as passed or failed. Passed candidates expose a scheduling form for the date, location, co-interviewers, and candidate-visible shared documentation.

The authenticated workspace also includes:

  • Users for listing and creating co-interviewers.
  • Invitations in the top-right account navigation for accepting or declining assignments.
  • Profile in the top-right account navigation for the logged-in user's identity and role.
  • Schedule for interviews grouped by date.
  • Interviewer sessions for changing status, editing prominent shared documentation, and posting private notes while an interview is started. Notes and shared-document changes arrive live through an authenticated streaming fetch; the app intentionally does not use EventSource, because the request needs the JWT authorization header.

The authenticated layout ends with a sitemap and useful-links footer. Update src/config/navigation.ts to add, remove, or reorder footer destinations.

Participants open the generated /participant/:invitationId URL without signing in. The opaque invitation ID authorizes the existing /api/interviews/:token API. Code-review questions are shown in a pull-request-style code panel with a review comment field. Answers are saved when navigating between questions and as they change, then Submit completes the interview. The countdown is derived from the backend acceptedAt timestamp plus the job duration so refreshing cannot reset it. Questions stay hidden until the participant explicitly accepts the invitation.

Scheduled candidates use /participant/meeting/:token. This public view shows the interview date, location, status, and read-only shared documentation. A token-authorized event stream updates the document immediately when an interviewer saves it in another browser. The participant view never receives interviewer notes or assessment reference answers.

Container

Build with docker build -t go-guess-frontend .. The production Nginx server serves the SPA and proxies /api to the Docker Compose service api:8080.
