The frontend was a Create React App scaffold (deprecated) where App.tsx was
still the stock 'Learn React' boilerplate — the implemented login/register pages
and stores were never mounted (no router). This swaps to Vite/TS5, fixes the
broken API client, wires a real router + dashboard, and lands on a runnable app.
Tooling swap (CRA -> Vite):
* Dropped react-scripts, web-vitals, @types/jest; added vite 6 + @vitejs/plugin-react
+ vitest 3 + jsdom; bumped typescript 4.9 -> 5.6, @types/node 16 -> 22.
* New vite.config.ts (with dev-server /api proxy -> backend, no CORS in dev),
tsconfig.json (target es2022, moduleResolution bundler, vite/client types),
tsconfig.node.json, vite-env.d.ts, root index.html.
* .env / .env.example (VITE_API_URL + VITE_API_TARGET). Renamed index.tsx ->
main.tsx (theme provider + CssBaseline). Deleted all CRA boilerplate
(App.css, logo.svg, App.test.tsx, reportWebVitals.ts, react-app-env.d.ts,
CRA index.html/logos/readme) + the orphaned empty web/src/ and mobile/ trees.
* node_modules 479MB -> 265MB; lockfile 695KB -> 198KB.
API client correctness (services/api.ts):
* Env var process.env.REACT_APP_* -> import.meta.env.VITE_*; dropped the
hardcoded http://solaria:8001/api (now /api via the dev proxy).
* Fixed contract mismatches: getCurrentUser /auth/me -> /users/me;
updateMedication PUT -> POST /:id; deleteMedication DELETE -> POST /:id/delete.
* Added refreshToken() (/auth/refresh) and server-side logout() (/auth/logout).
* Removed the /lab-results block (no backend route).
* 401 interceptor now attempts ONE silent refresh (deduped) before bouncing to
/login, instead of hard-redirecting on every 401.
* CreateMedicationRequest type now matches the backend (required route +
profile_id fields).
Router + dashboard:
* Real App.tsx with BrowserRouter: /login, /register (public), / (protected
Dashboard), catch-all -> /.
* New Dashboard.tsx: MUI AppBar + welcome card, loads the current user on mount,
logout button. The shell feature UIs get built into next.
* LoginPage/RegisterPage navigate to / (was /dashboard); store logout is now
async; AuthTokens type includes refresh_token.
* Minimal MUI theme.ts.
Verified: npm run build clean (TS5 strict + Vite), dev server serves the app +
proxies /api to the backend, vitest runs. Solaria round-trip confirmed all
corrected endpoints (/users/me 200, /auth/refresh 200, /auth/logout 204,
medication create 200).
