## 🎯 Priority Roadmap
|
||||
|
||||
### 🔥 HIGH PRIORITY (Next 2 Weeks)
|
||||
|
||||
#### 1. Custom PWA Icons
|
||||
**Why**: Branding, professionalism
|
||||
**Effort**: 2-3 hours
|
||||
**Impact**: High visibility
|
||||
|
||||
**Action Items**:
|
||||
```bash
|
||||
# Create 8 icon sizes for each brand:
|
||||
# Dexar: Purple (#a855f7) background + white logo
|
||||
# Novo: Green (#10b981) background + white logo
|
||||
|
||||
public/icons/dexar/
|
||||
├── icon-72x72.png
|
||||
├── icon-512x512.png
|
||||
└── ...
|
||||
|
||||
public/icons/novo/
|
||||
├── icon-72x72.png
|
||||
└── ...
|
||||
|
||||
# Update manifests to point to brand folders
|
||||
```
|
||||
|
||||
**Tools**: Figma, Photoshop, or [RealFaviconGenerator](https://realfavicongenerator.net/)
|
||||
|
||||
---
|
||||
|
||||
#### 2. Unit Testing
|
||||
**Why**: Code reliability, easier refactoring
|
||||
**Effort**: 1-2 weeks
|
||||
**Impact**: Development velocity, bug reduction
|
||||
|
||||
**Target Coverage**: 80%+
|
||||
|
||||
**Priority Test Files**:
|
||||
```typescript
|
||||
// 1. Services (highest ROI)
|
||||
cart.service.spec.ts // Test signal updates, cart logic
|
||||
api.service.spec.ts // Mock HTTP calls
|
||||
telegram.service.spec.ts // Test WebApp initialization
|
||||
|
||||
// 2. Components (critical paths)
|
||||
cart.component.spec.ts // Payment flow, validation
|
||||
header.component.spec.ts // Cart count, navigation
|
||||
item-detail.component.spec.ts // Add to cart, variant selection
|
||||
|
||||
// 3. Interceptors
|
||||
cache.interceptor.spec.ts // Verify caching logic
|
||||
```
|
||||
|
||||
**Quick Start**:
|
||||
```bash
|
||||
# Generate test with Angular CLI
|
||||
ng test --code-coverage
|
||||
|
||||
# Write first test
|
||||
describe('CartService', () => {
|
||||
it('should add item to cart', () => {
|
||||
service.addToCart(mockItem, mockVariant);
|
||||
expect(service.cartItems().length).toBe(1);
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
#### 3. Error Boundary & User Feedback
|
||||
**Why**: Graceful failures, better UX
|
||||
**Effort**: 1 day
|
||||
**Impact**: User trust, reduced support tickets
|
||||
|
||||
**Implementation**:
|
||||
```typescript
|
||||
// src/app/services/error-handler.service.ts
|
||||
@Injectable({ providedIn: 'root' })
|
||||
export class ErrorHandlerService {
|
||||
showError(message: string) {
|
||||
// Show toast notification
|
||||
// Log to analytics
|
||||
// Optionally send to backend
|
||||
}
|
||||
}
|
||||
|
||||
// Usage in cart.component.ts
|
||||
this.apiService.createPayment(data).subscribe({
|
||||
next: (response) => { /* handle success */ },
|
||||
error: (err) => {
|
||||
this.errorHandler.showError(
|
||||
'Не удалось создать платеж. Попробуйте позже.'
|
||||
);
|
||||
console.error(err);
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
**Add Toast Library**:
|
||||
```bash
|
||||
npm install ngx-toastr --save
|
||||
```
|
||||
|
||||

|
||||
|
||||
### ⚡ MEDIUM PRIORITY (Next Month)
|
||||
|
||||
#### 4. E2E Testing
|
||||
**Why**: Catch integration bugs, confidence in releases
|
||||
**Effort**: 3-5 days
|
||||
**Impact**: Release quality
|
||||
|
||||
**Recommended**: [Playwright](https://playwright.dev/) (better than Cypress for modern apps)
|
||||
|
||||
```bash
|
||||
npm install @playwright/test --save-dev
|
||||
npx playwright install
|
||||
```
|
||||
|
||||
**Critical Test Scenarios**:
|
||||
1. Browse categories → View item → Add to cart → Checkout
|
||||
2. Search product → Filter results → Add to cart
|
||||
3. Empty cart → Add items → Remove items
|
||||
4. Payment flow (mock SBP QR code response)
|
||||
5. Email/phone validation on success screen
|
||||
|
||||
---
|
||||
|
||||
#### 5. Analytics Integration
|
||||
**Why**: Data-driven decisions, understand users
|
||||
**Effort**: 1 day
|
||||
**Impact**: Business insights
|
||||
|
||||
**Recommended Setup**:
|
||||
```typescript
|
||||
// Yandex Metrica (best for Russian market)
|
||||
<!-- index.html -->
|
||||
<script>
|
||||
(function(m,e,t,r,i,k,a){
|
||||
// Yandex Metrica snippet
|
||||
})(window, document, "yandex_metrica_callbacks2");
|
||||
</script>
|
||||
|
||||
// Track events
|
||||
yaCounter12345678.reachGoal('ADD_TO_CART', {
|
||||
product_id: item.id,
|
||||
price: variant.price
|
||||
});
|
||||
```
|
||||
|
||||
**Key Metrics to Track**:
|
||||

|
||||
- Add to cart events
|
||||
- Checkout initiation
|
||||
- Payment success/failure
|
||||

||||
**Why**: Better UX, SEO, conversion rates
|
||||
**Effort**: 2-3 days
|
||||
**Impact**: User satisfaction
|
||||
|
||||
**Action Items**:

<picture>
|
||||
<source srcset="image.webp" type="image/webp">
|
||||
<img src="image.jpg" alt="Product">
|
||||
</picture>
|
||||
|
||||
// 2. Lazy Load Images
|
||||
<img loading="lazy" src="product.jpg">
|
||||
|
||||
// 3. Preload Critical Assets
|
||||
// index.html
|
||||
<link rel="preload" href="logo.svg" as="image">
|
||||
|
||||
// 4. Virtual Scrolling for Long Lists
|
||||
// npm install @angular/cdk
|
||||
<cdk-virtual-scroll-viewport itemSize="150">
|
||||
@for (item of items; track item.id) {
|
||||
<div>{{ item.title }}</div>
|
||||
}
|
||||
</cdk-virtual-scroll-viewport>
|
||||
```
|
||||
|
||||
**Measure First**:

## 🛠️ Technical Debt & Improvements
|
||||
|
||||
### Quick Wins (< 1 hour each)
|
||||
|
||||
1. **Environment Variables for API URLs**
|
||||
```typescript
|
||||
// Don't hardcode API URLs
|
||||
// Use environment.apiUrl consistently
|
||||
```
|
||||
|
||||
2. **Content Security Policy (CSP)**
|
||||
```nginx
|
||||
# nginx.conf
|
||||
add_header Content-Security-Policy "default-src 'self'; script-src 'self' 'unsafe-inline';";
|
||||
```
|
||||
|
||||
3. **Rate Limiting**
|
||||
```typescript
|
||||
// Prevent API spam
|
||||
import { debounceTime } from 'rxjs';
|
||||
|
||||
searchQuery$.pipe(
|
||||
debounceTime(300)
|
||||
).subscribe(/* search */);
|
||||
```
|
||||
|
||||
4. **Loading States**
|
||||
```html
|
||||
<!-- Show skeletons while loading -->
|
||||
@if (loading()) {
|
||||
<div class="skeleton"></div>
|
||||
} @else {
|
||||
<div>{{ content }}</div>
|
||||
}
|
||||
```
|
||||
|
||||
5. **SEO Meta Tags**
|
||||
```typescript
|
||||
// Use Angular's Meta service
|
||||
constructor(private meta: Meta) {}
|
||||
|
||||
ngOnInit() {
|
||||
this.meta.updateTag({
|
||||
name: 'description',
|
||||
content: this.product.description
|
||||
});
|
||||
}
|
||||
