# Phase 01.1 Plan 02: tRPC Foundation Summary
|
|
|
|
**Type-safe tRPC router with health and status procedures, Zod validation, and comprehensive tests**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** 6 min
|
|
- **Started:** 2026-01-30T12:52:38Z
|
|
- **Completed:** 2026-01-30T12:58:19Z
|
|
- **Tasks:** 2
|
|
- **Files modified:** 3
|
|
|
|
## Accomplishments
|
|
|
|
- Added health procedure returning { status, uptime, processCount }
|
|
- Added status procedure returning { server: {startedAt, uptime, pid}, processes: [] }
|
|
- Zod schemas for runtime output validation
|
|
- AppRouter type exported for client type-safety
|
|
- 16 tests covering procedures and schema validation
|
|
|
|
## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1: Install tRPC dependencies and create router foundation** - `437e76e` (done in prior session as part of Plan 01.1-01)
|
|
2. **Task 2: Define procedures matching HTTP endpoints with tests** - `551e516` (feat)
|
|
|
|
**Plan metadata:** (this commit)
|
|
|
|
_Note: Task 1 was completed as part of Plan 01.1-01 execution. This plan focused on Task 2._
|
|
|
|
## Files Created/Modified
|
|
|
|
- `src/trpc/router.ts` - Added appRouter with health/status procedures, Zod schemas
|
|
- `src/trpc/index.ts` - Export AppRouter type and schemas
|
|
- `src/trpc/router.test.ts` - 16 tests for procedures and validation
|
|
|
|
## Decisions Made
|
|
|
|
1. **Zod for output validation** - Ensures runtime type safety; procedures validate their outputs match declared schemas
|
|
2. **Match HTTP endpoint shapes** - health and status procedures return same data as existing `/health` and `/status` HTTP endpoints for consistency
|
|
|
|
## Deviations from Plan
|
|
|
|
### Auto-handled
|
|
|
|
**1. [Rule 3 - Blocking] Task 1 already completed**
|
|
- **Found during:** Task 1 verification
|
|
- **Issue:** tRPC foundation files already existed from Plan 01.1-01 execution
|
|
- **Resolution:** Verified existing files met Task 1 requirements, proceeded to Task 2
|
|
- **Impact:** None - reduced work, no code changes needed for Task 1
|
|
|
|
## Issues Encountered
|
|
|
|
None - plan executed as expected.
|
|
|
|
## User Setup Required
|
|
|
|
None - no external service configuration required.
|
|
|
|
## Next Phase Readiness
|
|
|
|
- tRPC router ready for HTTP adapter integration (Plan 01.1-06)
|
|
- Type-safe contract established for CLI-server communication
|
|
- Procedures match existing HTTP endpoint contracts
