# Dependency graph
|
|
requires:
|
|
- 01-02 (BackendType from registry.ts, reducer.test.ts TDD stub)
|
|
- 01-03 (completes schemas layer alongside store layer)
|
|
provides:
|
|
- WizardState interface, WizardAction union type, INITIAL_STATE constant (src/store/types.ts)
|
|
- Pure wizardReducer function (src/store/reducer.ts)
|
|
- WizardContext, WizardProvider, useWizard hook (src/store/context.tsx)
|
|
- App.tsx wired with WizardProvider as root context
|
|
affects:
|
|
- Phase 2 (script generator reads WizardState.remote and WizardState.deployment)
|
|
- Phase 3 (form components call useWizard to read/write state)

# Phase 01 Plan 04: WizardState Store Summary
|
|
|
|
**Pure reducer + React Context store for wizard state: types, wizardReducer (8 tests green), WizardProvider, and useWizard hook wired into App.tsx with zero browser storage access (SECU-03)**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** ~2 min
|
|
- **Started:** 2026-03-26T10:23:09Z
|
|
- **Completed:** 2026-03-26T10:24:49Z
|
|
- **Tasks:** 2
|
|
- **Files modified:** 4
|
|
|
|
## Accomplishments
|
|
|
|
- `src/store/types.ts` created: `WizardState` interface with `remote` (name, backendType, params) and `deployment` (includeInstall, configPath, scriptTargets) sub-objects; `WizardAction` union type (6 action variants); `INITIAL_STATE` constant; re-exports `BackendType` from registry for single-import convenience
|
|
- `src/store/reducer.ts` created: pure `wizardReducer` handling all 6 action types via spread operators — no mutation, no side effects
|
|
- All 8 tests in `src/store/reducer.test.ts` pass GREEN (covering INIT, SET_STEP, SET_BACKEND_TYPE, SET_REMOTE_NAME, SET_REMOTE_PARAMS, SET_DEPLOYMENT, RESET, purity check)
|
|
- `src/store/context.tsx` created: `WizardProvider` (useReducer wrapper), `useWizard` hook (throws on missing provider), typed `WizardContextValue` interface
|
|
- `src/App.tsx` updated: content wrapped in `<WizardProvider>` — all future components can call `useWizard()` without prop drilling
|
|
- Full test suite: 23 tests pass across 3 files (registry.test.ts, schemas/index.test.ts, store/reducer.test.ts)
|
|
- `npm run build` exits 0 — no TypeScript errors
|
|
- SECU-03 verified: no `localStorage`, `sessionStorage`, or `IndexedDB` method calls in any store file
|

## Task Commits

|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1: Implement WizardState types and pure reducer** - `3fade79` (feat)
|
|
2. **Task 2: Create WizardContext provider and wire into App** - `2eef722` (feat)
|
|
|
|
**Plan metadata:** _(committed after SUMMARY.md — see final commit)_

## Files Created/Modified
|
|
|
|
- `src/store/types.ts` — WizardState, WizardAction, INITIAL_STATE, re-exports BackendType
|
|
- `src/store/reducer.ts` — pure wizardReducer function (8 tests)
|
|
- `src/store/context.tsx` — WizardContext, WizardProvider, useWizard hook
|
|
- `src/App.tsx` — wrapped with WizardProvider
|
|
|
|
## Decisions Made
|
|
|
|
- `useReducer + Context API` chosen over Zustand/Redux — zero external dependencies, sufficient for a 4-step linear wizard
|
|
- `useWizard()` throws `Error('useWizard must be used inside <WizardProvider>')` on missing provider — fail fast, no silent undefined propagation
|
|
- `scriptTargets` defaults to `['intune', 'rmm']` (both selected) — users opt-out rather than opt-in, reducing the chance of incomplete output
|
|
|
|
## Deviations from Plan
|
|
|
|
None - plan executed exactly as written.
|
|
|
|
## Issues Encountered
|
|
|
|
None. TDD RED→GREEN flow was clean. Build passed on first attempt.
|
|
|
|
## User Setup Required
|
|
|
|
None.
|
|
|
|
## Next Phase Readiness
|
|
|
|
- All store types exported from `src/store/types.ts` — Phase 3 form components import `WizardState`, `WizardAction`, `useWizard`
|
|
- `src/store/context.tsx` exports `useWizard` — components call `const { state, dispatch } = useWizard()` to read/write wizard data
|
|
- Phase 2 script generator reads `state.remote.backendType`, `state.remote.name`, `state.remote.params` and `state.deployment` for config/script output
|
|
- Foundation layer complete: registry + schemas + store all implemented and tested (23 tests green)
