# Code Review Report: Story 3.4 - PWA Install Prompt & Manifest
|
|
|
|
**Date:** 2026-01-23
|
|
**Reviewer:** Antigravity
|
|
**Status:** ✅ APPROVED (with minor notes)
|
|
|
|
## Executive Summary
|
|
The implementation for Story 3.4 (PWA Install Prompt & Manifest) is **complete and verifies against all Acceptance Criteria**. The architecture follows the specified "Logic Sandwich" pattern, keeping UI components clean and delegating logic to services and stores. Unit tests are present and passing.
|
|
|
|
## Acceptance Criteria Verification
|
|
|
|
| Criteria | Status | Notes |
|
|
| ------------------------- | ------ | ------------------------------------------------------------------------------------------------------------------------------- |
|
|
| **Valid `manifest.json`** | ✅ PASS | Implemented in `src/app/manifest.ts` with standalone mode and correct icons. |
|
|
| **Install Prompt Logic** | ✅ PASS | `InstallPromptService` correctly handles `beforeinstallprompt` and `appinstalled` events. |
|
|
| **Custom UI** | ✅ PASS | `InstallPromptButton` provides a non-intrusive UI element. |
|
|
| **Engagement Logic** | ✅ PASS | `EngagementTracker` and `InstallPromptButton` strictly enforce showing the prompt only after engagement (1+ completed session). |
|
|
| **Standalone Mode** | ✅ PASS | Correctly configured in manifest and detected by service. |
|
|
|
|
## Architectural Analysis
|
|
|
|
### Strengths
|
|
- **Logic Sandwich Pattern**: `InstallPromptButton` only relies on `InstallPromptStore` (state) and `EngagementTracker` (data), calling `InstallPromptService` for actions. This is excellent separation of concerns.
|
|
- **State Management**: Zustand store (`InstallPromptStore`) effectively manages the ephemeral `beforeinstallprompt` event.
|
|
- **Atomic Selectors**: The UI component uses atomic selectors (`s => s.isInstallable`) to minimize re-renders.
|
|
|
|
### Issues Found
|
|
|
|
#### Minor / Maintenance
|
|
- **Lint Error**: `src/services/install-prompt-service.ts` contains an explicit `any` cast.
|
|
```typescript
|
|
(window.navigator as any).standalone === true; // iOS Safari
|
|
```
|
|
*Recommendation*: Extend the `Navigator` interface in a `d.ts` file to include the `standalone` property for better type safety, or disable the lint rule for this specific line if type augmentation is overkill.
|
|
|
|
## Verification
|
|
- **Automated Tests**:
|
|
- `src/app/manifest.test.ts`: passed
|
|
- `src/services/install-prompt-service.test.ts`: passed
|
|
- `src/services/engagement-tracker.test.ts`: passed
|
|
- **Linting**: 1 error found (noted above).
|
|
|
|
## Recommendations
|
|
1. **Fix Lint Error**: Add a global type declaration for `navigator.standalone` to remove the `any` cast.
|
|
2. **Engagement Optimization**: Currently polling `EngagementTracker` every 5 seconds. Ideally, this should react to DB changes, but polling is acceptable for MVP.
|
|
|
|
## Conclusion
|
|
The story is **READY TO MERGE** / **COMPLETE**. The minor lint issue does not block functionality or stability.
