packages/web/src/App.tsx

httpBatchLink URL set to /trpc (proxied by Vite in dev, same-origin in prod)

QueryClient defaults: refetchOnWindowFocus=false, retry=1

Temporary App.tsx with health check to prove tRPC connection

tRPC client: createTRPCReact<AppRouter>() in lib/trpc.ts

Provider stack: trpc.Provider > QueryClientProvider > App

Phase 16 Plan 03: tRPC Client Wiring Summary

tRPC React Query client wired to AppRouter with httpBatchLink, React Query provider, and health check verification

Tasks: 2

Accomplishments

tRPC React Query client created with full AppRouter type inference
React Query provider configured with sensible defaults (no refetch on focus, single retry)
httpBatchLink configured for /trpc URL (Vite dev proxy forwards to backend at 127.0.0.1:3847)
Temporary App.tsx with trpc.health.useQuery() proves end-to-end type-safe data fetching
Vite build passes with full type checking

Task Commits

Each task was committed atomically:

Task 1: Install tRPC React Query dependencies - 603d908 (feat)
Task 2: Wire tRPC React Query client with providers - 0d5645f (feat)

Files Created/Modified

packages/web/src/lib/trpc.ts - tRPC React Query client with createTRPCReact and httpBatchLink
packages/web/package.json - Added @trpc/client, @trpc/react-query, @tanstack/react-query, @codewalk-district/shared
packages/web/src/main.tsx - Root component with trpc.Provider and QueryClientProvider wrapping App
packages/web/src/App.tsx - Temporary health check component using trpc.health.useQuery()

Decisions Made

httpBatchLink URL set to /trpc relying on Vite dev proxy (no absolute URL needed)
QueryClient configured with refetchOnWindowFocus=false and retry=1 for development ergonomics
tsconfig.app.json project references to shared package not needed (npm workspaces symlink handles resolution, skipLibCheck avoids third-party declaration issues)

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None

User Setup Required

None - no external service configuration required.

Next Phase Readiness

tRPC client fully operational with type-safe hooks
All subsequent UI screens (dashboard, detail, inbox) can use trpc.{procedure}.useQuery() for data fetching
Ready for 16-04: React Router Setup

Phase: 16-frontend-scaffold Completed: 2026-02-04
