# Dependency graph
requires: []
provides:
- Vite 6 + React 18 + TypeScript 5 SPA scaffold with working dev server and build
- Tailwind v4 configured via @tailwindcss/vite plugin (no postcss/tailwind.config.js)
- All Phase 1 production dependencies: zod, react-hook-form, @hookform/resolvers
- Vitest 4 configured for node environment, exits 0 with no test files

key-decisions:
- "Tailwind v4 via @tailwindcss/vite plugin — no postcss.config.js, no tailwind.config.js, no content globs"
- "Separate vitest.config.ts (not merged into vite.config.ts) for clean concern separation"
- "passWithNoTests: true in vitest.config.ts so CI/CD passes before any tests are written"
- "Zod v4 + @hookform/resolvers v5 installed together (resolvers v5 required for Zod v4 compatibility)"
patterns-established:
- "Tailwind v4: use @import 'tailwindcss' in CSS, @tailwindcss/vite in vite.config.ts — no other config"
- "vitest: always set passWithNoTests: true so empty test suites don't break CI"

# Phase 01 Plan 01: Project Scaffold Summary
**Vite 6 + React 18 + TypeScript 5 SPA with Tailwind v4 via @tailwindcss/vite plugin and Vitest 4 configured for node-environment unit tests**
## Performance
- **Duration:** ~4 min
- **Started:** 2026-03-26T09:09:47Z
- **Completed:** 2026-03-26T09:13:12Z
- **Tasks:** 2
- **Files modified:** 12
## Accomplishments
- Vite 6 React TypeScript scaffold created from scratch (npm create vite CLI cancelled in non-interactive shell — files created manually to match template exactly)
- Tailwind v4 installed and configured via @tailwindcss/vite plugin with single `@import "tailwindcss"` CSS directive
- All Phase 1 dependencies installed: zod@4, react-hook-form@7, @hookform/resolvers@5, vitest@4, @testing-library/react
- Vitest configured with `environment: 'node'`, `globals: true`, and `passWithNoTests: true` — exits 0 with no test files
## Task Commits
Each task was committed atomically:
1. **Task 1: Scaffold and install all Phase 1 dependencies** - `237d06b` (feat)
2. **Task 2: Configure Vitest for pure-function unit tests** - `d132413` (feat)
**Plan metadata:** _(committed after SUMMARY.md — see final commit)_
## Files Created/Modified
- `vite.config.ts` — Vite build config with react() and tailwindcss() plugins
- `vitest.config.ts` — Vitest config: environment node, globals, passWithNoTests
- `src/index.css` — Tailwind v4 entry point: `@import "tailwindcss"`
- `src/App.tsx` — Minimal placeholder with Tailwind classes (p-4, text-2xl, font-bold)
- `src/main.tsx` — React 18 root render with StrictMode, imports index.css
- `src/vite-env.d.ts` — Vite client type declarations (enables CSS imports in TypeScript)
- `tsconfig.json` — Project references config
- `tsconfig.app.json` — App TypeScript config (strict, bundler mode, ESNext)
- `tsconfig.node.json` — Node TypeScript config for vite.config.ts
- `index.html` — HTML entry point with root div and module script
- `package.json` — All dependencies declared, scripts: dev, build, test, preview
- `.gitignore` — Standard Vite gitignore (node_modules, dist)
## Decisions Made
- Used `@tailwindcss/vite` plugin (Tailwind v4) rather than postcss approach — no `tailwind.config.js` or `content` globs needed
- Installed `@hookform/resolvers@5` which is required for Zod v4 compatibility (v3/v4 resolvers only work with Zod v3)
- Kept `vitest.config.ts` separate from `vite.config.ts` for clean separation of build vs test concerns
- Added `passWithNoTests: true` to Vitest config so the test runner exits 0 before any tests are written
## Deviations from Plan
### Auto-fixed Issues
**1. [Rule 3 - Blocking] Added src/vite-env.d.ts for TypeScript CSS import support**
- **Found during:** Task 1 (build verification)
- **Issue:** `tsc -b` failed with `error TS2307: Cannot find module './index.css'` — TypeScript has no built-in knowledge of CSS imports
- **Fix:** Created `src/vite-env.d.ts` with `/// <reference types="vite/client" />` which provides CSS module type declarations from Vite
- **Files modified:** `src/vite-env.d.ts` (created)
- **Verification:** `npm run build` succeeds with exit 0 after fix
- **Committed in:** `237d06b` (Task 1 commit)
**2. [Rule 1 - Bug] Added passWithNoTests: true to vitest.config.ts**
- **Found during:** Task 2 (Vitest verification)
- **Issue:** `npx vitest run` exited with code 1 when no test files exist — plan requires exit code 0
- **Fix:** Added `passWithNoTests: true` to test config object in vitest.config.ts
- **Files modified:** `vitest.config.ts`
- **Verification:** `npx vitest run` exits 0 with "No test files found, exiting with code 0"
- **Committed in:** `d132413` (Task 2 commit)
---
**Total deviations:** 2 auto-fixed (1 blocking, 1 bug)
**Impact on plan:** Both fixes necessary for the plan's success criteria (build exits 0, vitest exits 0). No scope creep.
## Issues Encountered
- `npm create vite@latest . -- --template react-ts` was cancelled by the interactive CLI in the non-interactive shell environment. Resolved by manually creating all template files matching the react-ts template exactly.
## User Setup Required
None - no external service configuration required.
## Next Phase Readiness
- Full build toolchain operational: `npm run dev`, `npm run build`, `npx vitest run` all succeed
- All Phase 1 dependencies installed and ready for use in downstream plans
- Tailwind v4 utility classes confirmed working in App.tsx (p-4, text-2xl, font-bold classes produce expected styles in built CSS)
