# Implementation Plan: unified-app

## Overview

This plan consolidates the Reports App and Data Entry App frontends into a single unified SPA. The implementation follows a pragmatic monolith approach with module isolation through error boundaries and lazy loading.

**Key principles:**
- Single build, single IIS site deployment
- Module isolation via error boundaries (errors in one module don't crash the other)
- Lazy loading for each module (only load what the user navigates to)
- Shared components from `src/shared/` (auth, companies, period selectors)
- CSS system from reports-app preserved and enhanced

**Worktree location:** `/mnt/e/proiecte/ab-worktrees/roa2web-unified-app`

## Phase 4: Error Boundaries & Resilience (0.25 days)

### Task 20: Create ErrorBoundary Component

**Objective**: Create reusable error boundary component.

**Files**:
- `/mnt/e/proiecte/ab-worktrees/roa2web-unified-app/src/shared/components/ErrorBoundary.vue` (create)

**Description**:
Create ErrorBoundary.vue component that:

1. Uses `onErrorCaptured` to catch child component errors
2. Displays user-friendly error message in Romanian
3. Provides "Retry" button (reloads page)
4. Provides "Go to Dashboard" button
5. Logs error details to console
6. Returns `false` from onErrorCaptured to prevent propagation

Template structure:
```vue
<template>
  <div v-if="error" class="module-error">
    <div class="error-icon">
      <i class="pi pi-exclamation-triangle"></i>
    </div>
    <h3>{{ moduleName }} a intampinat o eroare</h3>
    <p class="error-message">{{ error.message }}</p>
    <div class="error-actions">
      <Button label="Reincearca" icon="pi pi-refresh" @click="retry" />
      <Button label="Mergi la Dashboard" icon="pi pi-home" severity="secondary" @click="goHome" />

Using Vue Router's built-in async component handling:
```javascript
component: defineAsyncComponent({
  loader: () => import('@reports/views/DashboardView.vue'),
  loadingComponent: ModuleLoading,
  delay: 200,
  timeout: 10000
})
```

Or use Suspense in layout components.

**Files**:
- (verification task, no file modifications)

**Description**:
1. Run `npm run build`
2. Verify `dist/` output:
   - `assets/vendor-core.[hash].js` (vue, router, pinia)
   - `assets/vendor-primevue.[hash].js` (primevue components)
   - `assets/vendor-utils.[hash].js` (axios, date-fns)
   - `assets/vendor-charts.[hash].js` (chart.js - lazy)
   - `assets/vendor-export.[hash].js` (xlsx, jspdf - lazy)
   - Module chunks for reports and data-entry
   - CSS chunk

3. Check total bundle size <= sum of old apps
4. Verify source maps generated

**Dependencies**: Tasks 1-23

**Completion Criteria**:
- [x] Build completes without errors

- [x] Bundle size acceptable
- [x] Source maps present

---

### Task 26: Create README Documentation

**Objective**: Create README for the unified app.

**Files**:
- `/mnt/e/proiecte/ab-worktrees/roa2web-unified-app/unified-app-README.md` (create, will be moved to README.md later)

**Description**:
Create documentation covering:

1. **Overview**: Unified SPA combining Reports and Data Entry
2. **Quick Start**:
   - `npm install`
   - `npm run dev` (requires both backends running)
   - `npm run build`
3. **Architecture**:
   - Module structure
   - Shared components
   - Error boundaries
4. **URL Structure**
5. **Deployment**:
   - IIS configuration
   - Proxy setup
6. **Feature Flags**
7. **Development Guide**:
   - Adding new routes
   - Adding new components
   - CSS system reference

**Dependencies**: None

**Completion Criteria**:
- [x] README covers all sections
- [x] Quick start instructions work
- [x] Architecture explained clearly

---

### Task 27: Update Shared Stores for Dual API Support

**Objective**: Ensure shared stores work with both API endpoints.

**Files**:
- `/mnt/e/proiecte/ab-worktrees/roa2web-unified-app/src/shared/stores/auth.js` (update)
- `/mnt/e/proiecte/ab-worktrees/roa2web-unified-app/src/shared/stores/companies.js` (update)

**Description**:
The shared stores (auth, companies) need to work with both backends. Since authentication is handled by the Reports backend (port 8001), update:

1. **auth.js**: Use `/api/reports/auth/` for login/logout
2. **companies.js**: Use `/api/reports/companies/` for company list

Ensure the API base URL is correctly configured for the unified app's proxy setup.

**Dependencies**: Task 5, Task 3

**Completion Criteria**:
- [x] Auth store uses correct API path
- [x] Companies store uses correct API path
- [x] Login/logout flow works

---

### Task 28: End-to-End Integration Test

**Objective**: Verify the complete unified app works.

**Files**:
- (verification task, manual testing)

**Description**:
Manual testing checklist:

1. **Dev Server**:
   - [ ] `npm run dev` starts on port 3000
   - [ ] No console errors on load

2. **Login Flow**:
   - [ ] Navigate to `/login`
   - [ ] Login with valid credentials
   - [ ] Redirected to `/reports/dashboard`

3. **Reports Module**:
   - [ ] Dashboard loads with data
   - [ ] Navigate to Invoices
   - [ ] Navigate to Bank/Cash
   - [ ] Navigate to Trial Balance
   - [ ] Navigate to Telegram
   - [ ] Navigate to Cache Stats

4. **Data Entry Module**:
   - [ ] Navigate to `/data-entry` (Receipts List)
   - [ ] Navigate to `/data-entry/create` (Create Receipt)
   - [ ] Company selector preserved from Reports

5. **Module Switching**:
   - [ ] Switch from Reports to Data Entry
   - [ ] Switch from Data Entry to Reports
   - [ ] Selected company/period preserved

6. **Error Boundary**:
   - [ ] Intentionally break a component
   - [ ] Error shows in that module only
   - [ ] Other module still works

7. **Logout**:
   - [ ] Logout works
   - [ ] Redirected to login
   - [ ] All stores cleared

**Dependencies**: All previous tasks

**Completion Criteria**:
- [ ] All manual tests pass
- [ ] No console errors
- [ ] No visual regressions

---

## Testing Strategy

### During Implementation
- After each task, verify no import/build errors
- Test changed components individually
- Check browser console for errors

### Final Validation
- Run `npm run build` - must succeed
- Run `npm run preview` - test production build
- Test on different screen sizes (mobile, tablet, desktop)
- Verify lazy loading with Network tab (modules load on demand)

---

## Risk Mitigation

| Risk | Detection | Response |
|------|-----------|----------|
| CSS conflicts between modules | Visual testing shows wrong styles | Use scoped styles or module-specific CSS files |
| Import path errors | Build fails or runtime errors | Check all import aliases in vite.config.js |
| PrimeVue theme inconsistency | Different component styles | Ensure only saga-blue theme imported |
| Shared store contamination | Data appears in wrong module | Keep module stores separate, only use shared for auth/company/period |
| Lazy loading not working | Large initial bundle | Verify dynamic imports in router |
| Error boundary not catching | App crashes on error | Test with intentional errors |

---

## Notes for Implementation

1. **Always use absolute paths** from worktree root when creating files
2. **Test incrementally** - don't wait until the end to test
3. **Preserve existing functionality** - this is a migration, not a rewrite
4. **Reference existing files** - use reports-app as the primary reference
5. **Use saga-blue theme** consistently (reports-app theme)
6. **Login always uses Reports API** (port 8001) for authentication
7. **Keep module stores isolated** - no cross-module store dependencies
