…ion (#117)

  • Implement useOnboardingMutation to submit full name, username, and social links to POST /api/v1/users/onboarding
  • Implement useCheckUsername query hook with debouncing and client-side format validation
  • Implement useUserProfile query hook to fetch active authenticated user details from GET /api/v1/users/profile
  • Define query key factory userQueryKeys and export all shared TypeScript types
  • Add backend routes GET /api/v1/users/check-username and GET /api/v1/users/profile
  • Mount /api/v1/users/onboarding and preserve backward-compatible /api/v1/user/onboarding
  • Update OnboardingSchema and completeOnboarding controller to support and persist fullName
  • Integrate live TanStack hooks into /onboarding page replacing mock data and timers
  • Add comprehensive unit tests covering all hooks with 26 passing tests
  • Add onboarding with full name, username, and social links.
  • Check username availability and show format or availability feedback before submission.
  • Load the signed-in user’s profile and use it to prefill onboarding.
  • Keep the existing onboarding route available for compatibility.
  • To make the change easier to review, state the expected onboarding flow and username rules, and report test results only after confirming them.

📝 Walkthrough

Walkthrough

The API adds user profile and username-availability endpoints and accepts optional onboarding names. The web app adds hooks to load profiles, check usernames, and submit onboarding data. The onboarding page uses these hooks to prefill profile data, show validation and request status, and navigate after a successful submission.

Changes

Onboarding and user profile

Layer / File(s) Summary
API validation, handlers, and routes
apps/api/src/lib/user-schemas.ts, apps/api/src/controllers/*, apps/api/src/routes/*
Onboarding validation accepts optional trimmed fullName and name values. The onboarding update uses fullName, then name, when setting the display name. New handlers return profile data and check username availability. The user router is mounted at singular and plural paths, with onboarding also mounted at the plural path.
Web username checking and shared query data
apps/web/hooks/types.ts, apps/web/hooks/query-keys.ts, apps/web/hooks/query-keys.test.ts, apps/web/hooks/use-debounce.*, apps/web/hooks/use-check-username.*
The web hooks define user and onboarding types, user query keys, and a debounce hook. useCheckUsername validates and normalizes input, queries the availability endpoint, and exposes availability and checking state. Tests cover keys, input validation, and availability responses.
Web profile and onboarding hooks
apps/web/hooks/use-user-profile.*, apps/web/hooks/use-onboarding-mutation.*, apps/web/hooks/index.ts
useUserProfile fetches profile data. useOnboardingMutation submits onboarding data and invalidates the profile query after success. Tests cover successful requests, query invalidation, and a username-conflict response. The hooks and related types are re-exported.
Onboarding page integration
apps/web/components/pages/onboarding.tsx
The page prefills the full-name field from the profile when the field is empty. It replaces the local username check with the availability hook and submits valid onboarding data through the mutation hook. It displays validation and mutation status and navigates to /dashboard after success.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to bd05d

The server protects profile reads and onboarding writes, but the new profile cache is not tied to the signed-in account. On a shared browser, account switching could briefly show the previous account’s details. Whether the app clears that data when accounts change remains unverified.

Retained concerns

  • Medium · security · inferred: The new authenticated profile is cached under an account-independent key. If a browser switches accounts while its query provider remains mounted, the next account may briefly see the previous account’s cached profile before a fresh request completes.
Security review details

Security Blast Radius

  • inferred — The cache concern is limited to account transitions within a browser instance that retains its query provider; the inspected server path does not make one user’s profile accessible to an anonymous requester.

Security Findings and Attack Paths

  • inferred — On a shared browser, switching from account A to account B without clearing or remounting the query client could let B’s UI consume A’s cached profile under the unchanged profile key. An account switch retaining that cache was not established.

Trust Boundaries and Controls

  • observed — Profile retrieval and onboarding persistence require a session; username availability is intentionally callable without one. The onboarding write targets the authenticated user rather than an ID supplied in the request body.

Resilience and Maintainability Implications

  • observed — Concurrent claims of one username cannot rely on the availability response alone: a database uniqueness failure is handled as a conflict without reporting onboarding success.

Hardening Proposals

  • proposed — Partition authenticated profile queries by stable account identity, or clear the profile cache whenever the session identity changes; verify sign-out, sign-in, and same-browser account switching.

Handle non-string username query values.

Express 4 uses its simple query parser by default. A request such as ?username=a&username=b sets req.query.username to an array. The TypeScript cast does not change that runtime value, so rawUsername.trim() throws before schema validation. The error handler returns a 500 response for that request.

The bracketed form does not produce an object at req.query.username with this parser, but repeated keys are sufficient to trigger the failure. Check the value type before calling .trim().

🐛 Proposed fix
-    const rawUsername =
-      (req.query.username as string | undefined) ??
-      (req.params.username as string | undefined) ??
-      "";
+    const q = req.query.username;
+    const rawUsername =
+      typeof q === "string" ? q : typeof req.params.username === "string" ? req.params.username : "";

Stop the profile name from filling the field again after the user clears it.

fullName is in the dependency array. If the user deletes the whole name, fullName becomes "", the effect runs again, and it restores userProfile.name. The user cannot leave the field empty. Use a ref so the prefill runs only once.

🐛 Proposed fix
+  const prefilled = useRef(false);
   useEffect(() => {
-    if (userProfile?.name && !fullName) {
+    if (!prefilled.current && userProfile?.name) {
+      prefilled.current = true;
       setFullName(userProfile.name);
     }

Show the error state when the availability check fails.

The query can fail with a 5xx response or a network error. In that case, isAvailable stays null and isChecking is false. The page then shows no indicator and no message, and the submit button stays disabled. The user gets no feedback. Return query.isError together with an error message, and render that message on the page.

Based on learnings: "store the failure in a dedicated error state and render it as user-facing feedback near the form; don't fail silently."
