📝 Walkthrough

Walkthrough

The pull request adds backend authentication and payment-method APIs, web authentication and user pages, a mobile login flow, shared UI components, and backend CI configuration.

Changes

Backend API

Layer / File(s) Summary
Backend data and runtime foundation
backend/.gitignore, backend/.python-version, backend/pyproject.toml, backend/app/db/*, backend/app/models/*, backend/app/schemas/*
The backend defines Python 3.11 configuration, SQLAlchemy setup, user and payment-method models, and Pydantic request and response schemas.
Supabase authentication flow
backend/app/db/supabase.py, backend/app/services/auth_service.py, backend/app/dependencies/auth.py, backend/app/routes/auth.py, backend/app/main.py
The backend authenticates users through Supabase, manages access-token cookies, resolves database profiles, and registers authentication routes.
Payment-method API and service
backend/app/services/payment_method_service.py, backend/app/dependencies/payment_methods.py, backend/app/routes/payment_method.py
The backend adds authenticated payment-method creation, listing, and deletion with ownership checks and error mapping.
Backend validation and CI
backend/tests/*, .github/workflows/backend-test.yml
Tests cover payment-method routes and service behavior. GitHub Actions runs the backend pytest suite with PostgreSQL 15.

Web application

Layer / File(s) Summary
Web authentication and application shell
web/src/app/(auth)/sign-in/*, web/src/app/api/axios.ts, web/src/app/layout.tsx, web/src/contexts/AuthContext.tsx, web/src/components/AuthGuard/*, web/src/components/ToastProvider.tsx, web/src/proxy.ts
The web app adds sign-in, authentication state, protected routes, role checks, credentialed API requests, and toast notifications.
User layout and dashboard
web/src/app/user/layout*, web/src/components/Sidebar/*, web/src/app/user/dashboard/*, web/src/components/Dashboard/*
The web app adds responsive user navigation and a dashboard with statistics, activity, transactions, and budget goals.
Payment-method management
web/src/app/user/payment-methods/*, web/src/components/Modal/*
The web app adds payment-method loading, creation, deletion, notifications, empty states, and confirmation actions.
Transaction history
web/src/app/user/transactions/*
The web app adds month-filtered mock transaction history with desktop and mobile layouts.
Web runtime configuration
web/package.json, web/.gitignore, web/src/app/globals.css
The web app adds runtime packages, an ignored references/ directory, and theme variables for application states.

Mobile authentication entry

Layer / File(s) Summary
Mobile login route and screen
mobile/src/app/(auth)/*, mobile/src/app/index.tsx
The mobile app adds a login stack and responsive login screen. The root route redirects to login.
Mobile build configuration
mobile/eas.json, mobile/package.json
Preview and production profiles target Android APK output. The app adds @expo/vector-icons.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to 5bcf5

The current head leaves authentication and route protection unsafe for deployment: mobile sign-in does nothing, web API calls target localhost, protected user routes are not covered, and shared authentication state can affect the wrong session. Backend errors may also expose internal details, and transaction dates can appear in the wrong month. These concrete correctness, security, and availability issues should be fixed before merge.

Make transaction rows either interactive or static.

The desktop row and mobile card have no link or event handler. The stylesheet applies pointer and hover cues, and the mobile card shows ChevronRight. This signals an action that cannot occur.

  • web/src/app/user/transactions/page.tsx#L123-L131: Add an accessible transaction-detail action, or render a static row without interaction cues.
  • web/src/app/user/transactions/page.tsx#L153-L171: Add the same accessible action, or remove ChevronRight.

Inline comments:
In `@backend/app/db/supabase.py`:
- Line 14: Replace the module-level Supabase client used by
sign_in_with_password() and sign_out() with request-scoped isolation, or
explicitly bind sign-out to the caller’s token from the request cookie. Ensure
concurrent requests cannot share stored auth sessions or cause /logout to revoke
another user’s session.

In `@backend/app/dependencies/auth.py`:
- Around line 44-48: Update the exception handling around the authentication
flow to re-raise existing HTTPException instances unchanged, preserving their
status codes and details. For other exceptions, log the full exception
server-side and raise a generic 401 authentication error without exposing
internal error text; modify the handler identified by the current `except
Exception as e` block.

In `@backend/app/routes/auth.py`:
- Around line 37-39: Update the exception handling around the authentication
route to catch expected authentication failures explicitly and return a generic
401 detail without exposing exception text. Handle unexpected database or
Supabase failures separately by logging them server-side and returning a generic
500 response; do not map all exceptions through the existing broad handler.

In `@backend/app/routes/payment_method.py`:
- Around line 41-44: Update the payment-method route around
payment_method_service.get_all to catch only SQLAlchemyError, log the database
failure, and raise a generic HTTP 500 response without including exception text;
allow other exceptions to propagate to FastAPI’s default handler, and add a
route test verifying database error messages are not exposed.

In `@mobile/src/app/`(auth)/login.tsx:
- Around line 51-53: Update the login screen’s TouchableOpacity to invoke the
mobile authentication flow matching the existing /auth/login behavior, and add
pending-request state so onPress is disabled or ignored during submission.
Preserve the existing button styling and Sign in label while wiring the handler
through onPress.

In `@web/src/app/`(auth)/sign-in/page.tsx:
- Around line 163-187: Add persistent, associated labels for the email and
password inputs in the sign-in form, using matching label/input identifiers; add
a descriptive aria-label to the icon-only passwordToggleBtn that reflects
whether it will show or hide the password.

In `@web/src/app/api/axios.ts`:
- Around line 3-5: Update the axios instance configuration in api to use the
deployment-provided API URL instead of hardcoded localhost, and validate that
the required environment configuration is present so startup or deployment fails
when it is missing. Preserve withCredentials and the existing API path suffix.

In `@web/src/app/user/transactions/page.tsx`:
- Around line 55-62: Use UTC consistently for transaction month filtering and
display: update getMonthYearString, getShortMonth, and the related date-based
logic to use UTC getters instead of viewer-local getters, including the getDate
usage noted in the comment. Ensure ISO timestamps ending in Z remain grouped and
rendered by their UTC month.

In `@web/src/app/user/transactions/transactions.module.css`:
- Around line 25-37: Update the .filterSelect focus styling to restore a clearly
visible keyboard focus indicator, replacing the outline: none rule with an
accessible focus-visible treatment while preserving the existing appearance for
unfocused controls.

In `@web/src/components/Modal/Modal.tsx`:
- Around line 18-47: Update the Modal component to use an accessible dialog
implementation: add role="dialog", aria-modal="true", and an accessible label;
move focus into the modal on open, trap Tab navigation within it, restore focus
to the triggering element on close, and invoke onClose for Escape. Keep the
existing close button, message, and action behavior intact.

In `@web/src/components/Sidebar/Sidebar.tsx`:
- Around line 50-56: Update the mobile menu button in Sidebar to provide an
accessible name and expose its expanded state using the existing isMobileOpen
value; preserve toggleMobileMenu as the click handler and associate the control
with the mobile navigation content where supported.
- Around line 22-28: Update the menuItems definition in Sidebar to remove or
otherwise hide the Categories & Budgets, Goals, and Settings entries until
corresponding routes exist; preserve navigation for the implemented Dashboard,
Transactions, and Payment Methods pages.

In `@web/src/contexts/AuthContext.tsx`:
- Around line 30-45: Update AuthContext’s checkSession initialization flow to
ignore stale /auth/me success or failure results once login() or logout() has
changed the authentication state. Track a request version or cancellation guard
shared with login() and logout(), invalidate the pending initialization before
those methods update state, and only allow the current request to call setUser
or setIsLoading.

In `@web/src/proxy.ts`:
- Around line 5-7: Update roleAccessMap and the proxy route matcher to cover the
/user route tree used by the application, while preserving the required access
roles. Change denied-route handling so unauthorized requests redirect to an
unprotected forbidden page rather than back to /dashboard, preventing redirect
loops; update all corresponding branches in the proxy logic.

supabase-py v2.31.0 gotrue_client.py sign_in_with_password _save_session sign_out

💡 Result:

In supabase-py v2.31.0, the auth flow manages user sessions through the GotrueClient (available in both sync and async variants) [1][2]. Sign-in and Session Management When you call sign_in_with_password, the client authenticates the user with the Supabase Auth API [3][4]. Upon a successful response, the client internalizes the session data [1][5]. The _save_session method is an internal utility used by the client to persist this session (typically in an internal state or memory, depending on the environment) and notify authentication state change subscribers [6]. If you are working in environments like FastAPI or other web frameworks, you are responsible for retrieving the session (e.g., from the auth_response object) and managing how it is stored across requests, such as in cookies or server-side sessions [7]. Note that manually setting an Authorization header does not automatically populate the internal session state used by methods like get_user [8]. Sign-out and Cleanup Calling sign_out is essential not only for revoking the session on the server but also for cleaning up client-side resources [9][10][11]. 1. Session Revocation: It removes the session locally and, by default, communicates with the Supabase API to terminate the session globally (other scopes like 'local' are also supported) [9][5][12]. 2. Resource Cleanup: In supabase-py, it is explicitly required to call sign_out to ensure that background processes, such as Realtime WebSocket connections, are properly terminated [10][11]. Failure to do so can lead to resource leaks and processes that hang upon application exit [10][11]. Technical Note on v2.31.0 The library maintains feature parity with the JavaScript GoTrue client [1][13][2]. Internal methods like _save_session are generally considered private implementation details and should be treated as such [6]. Recent updates have focused on ensuring that authentication state changes (like those triggered by sign-in) do not inadvertently overwrite headers in other client components, such as the admin client [14].

Isolate the Supabase auth client per request.

sign_in_with_password() stores the session on the client, and /logout calls sign_out() without using the caller's cookie. A login from another request can therefore cause logout to revoke the wrong user's session. Use a request-scoped client, or pass the caller's token to an explicitly token-bound revocation path.

Preserve expected HTTP errors and do not return internal error text.

This handler catches the HTTPException instances raised on Lines 30 and 38. It converts the intended 401 or 404 response into a new 401 response. It also returns the caught Supabase or database error text in detail.

Re-raise HTTPException. For other failures, log the exception server-side and return a generic authentication error.

Do not return unexpected exception text to the client.

Line 39 exposes str(e) and maps database or Supabase failures to 401 Unauthorized. Catch expected authentication failures explicitly and return a generic 401 response. Log unexpected failures on the server and return a generic 500 response.

Handle database failures without exposing exception text.

get_all() executes a SQLAlchemy query, but this route catches every Exception and returns str(e) with HTTP 400. Catch SQLAlchemyError, log it, and return a generic HTTP 500 response. Let other exceptions reach FastAPI’s default 500 handler. Add a route test that asserts database errors do not expose their messages.

Connect the button to the authentication flow.

TouchableOpacity has no onPress, so tapping Sign in does nothing. Implement the mobile equivalent of the existing /auth/login flow, then pass the handler to onPress and prevent duplicate submissions while the request is pending.

Make the confirmation modal keyboard-operable.

Lines 22-47 render a visual modal only. Focus remains in the background when it opens. The component has no dialog semantics, focus trap, focus restoration, or Escape-key close behavior.

Use an accessible dialog implementation. It must move focus into the dialog, keep Tab navigation inside it, restore focus to the trigger when it closes, and expose role="dialog" with aria-modal="true" and an accessible label.

Remove or implement unreachable navigation routes.

The supplied PR route outline has no pages for /user/categories, /user/goals, or /user/settings. These links can navigate users to 404 pages. Hide these entries until their pages exist, or add the page routes.

Proposed fix
 const menuItems = [
   { name: "Dashboard", path: "/user/dashboard", icon: LayoutDashboard },
   { name: "Transactions", path: "/user/transactions", icon: ArrowRightLeft },
-  { name: "Categories & Budgets", path: "/user/categories", icon: PieChart },

-  { name: "Goals", path: "/user/goals", icon: Target },

Name the mobile navigation control and expose its state.

The icon-only button has no accessible name. It does not expose whether the mobile navigation is open. Screen-reader users cannot identify or verify the control state.

Prevent session initialization from overwriting an explicit login.

The initial /auth/me request can complete after the sign-in page calls login(). If that request was sent before the login cookie existed, its failure resets user to null after login succeeds. Track the session request version, or cancel and ignore stale initialization results after login() and logout().

Protect the routes that the application serves.

The supplied user layout and sign-in flow use /user/*, but this route map and matcher only cover /dashboard. The proxy does not run for /user/dashboard. Also, a denied request to /dashboard redirects to the same protected route and loops. Match the /user route tree and redirect denied users to an unprotected forbidden page.
