Follow-up to PR #406 — addresses the two items deferred from the audit:
#7 — Centralize auth helpers
- New `requireSessionUser(request)` in lib/auth/session.server.ts that
returns the user or throws a redirect to /auth/login.
- New `requireSessionUserJson(request)` companion that throws a 401 JSON
response (for fetcher/JSON endpoints).
- Replace the repeated
const user = await getSessionUser(request);
if (!user) return redirect("/auth/login");
pattern across 18 route loaders/actions. Removes the duplicated guard
preamble and gives a single chokepoint to evolve later (e.g., for
terms-version gating).
#8 — Extract heavy loaders into .server.ts siblings
- routes/home.tsx → home.server.ts (DB count query + listActivities +
listRecentPublicActivities)
- routes/users.$username.tsx → users.$username.server.ts (user lookup +
follow state + counts + listPublicRoutes/Activities + persona check)
- routes/settings.connections.tsx → settings.connections.server.ts
(connected_services join + manifest merge)
Each route file shrinks to a thin delegator: `loader` calls
`loadXxx(request)`. The component module no longer transitively pulls
`getDb` and Drizzle schema into its import graph — Vite's tree-shake
already strips server-only code from the client bundle, but the
explicit `.server.ts` suffix makes that contract local and auditable.
Other 17 routes that mix loader/action with components are left as-is
for now: they're each small enough that the split adds churn without
buying much clarity. The pattern is documented by the three examples;
the rest can convert opportunistically when they grow.
Tests:
- lib/auth/session.server.test.ts (4 cases — redirect for missing
cookie, redirect for ghost userId, success path, JSON 401 variant)
Full repo: pnpm typecheck, pnpm lint, pnpm test all green
(181 passed | 31 integration-gated skipped).
