🛡️ 路由守卫

1. 认证守卫

typescript
// core/guards/auth.guard.ts
import { Injectable } from '@angular/core';
import { CanActivate, Router, ActivatedRouteSnapshot, RouterStateSnapshot } from '@angular/router';
import { AuthService } from '../services/auth.service';

@Injectable({
  providedIn: 'root'
})
export class AuthGuard implements CanActivate {
  constructor(
    private authService: AuthService,
    private router: Router
  ) {}

  canActivate(
    route: ActivatedRouteSnapshot,
    state: RouterStateSnapshot
  ): boolean {
    if (this.authService.isAuthenticated()) {
      return true;
    } else {
      this.router.navigate(['/auth/login'], {
        queryParams: { returnUrl: state.url }
      });
      return false;
    }
  }
}

2. 管理员守卫

typescript
// core/guards/admin.guard.ts
import { Injectable } from '@angular/core';
import { CanActivate, Router } from '@angular/router';
import { AuthService } from '../services/auth.service';

@Injectable({
  providedIn: 'root'
})
export class AdminGuard implements CanActivate {
  constructor(
    private authService: AuthService,
    private router: Router
  ) {}

  canActivate(): boolean {
    if (this.authService.isAdmin()) {
      return true;
    } else {
      this.router.navigate(['/']);
      return false;
    }
  }
}

🎨 样式和主题

1. 全局样式

scss
// styles.scss
@import '~@angular/material/theming';
@include mat-core();

// 定义主题颜色
$primary: mat-palette($mat-blue);
$accent: mat-palette($mat-orange);
$warn: mat-palette($mat-red);

// 创建主题
$theme: mat-light-theme($primary, $accent, $warn);
@include angular-material-theme($theme);

// 全局样式
* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}

body {
  font-family: 'Roboto', sans-serif;
  line-height: 1.6;
  color: #333;
}

.container {
  max-width: 1200px;
  margin: 0 auto;
  padding: 0 20px;
}

// 响应式设计
@media (max-width: 768px) {
  .container {
    padding: 0 10px;
  }
}

2. 组件样式

scss
// product-card.component.scss
.product-card {
  border: 1px solid #e0e0e0;
  border-radius: 8px;
  overflow: hidden;
  transition: transform 0.3s ease, box-shadow 0.3s ease;
  cursor: pointer;

  &:hover {
    transform: translateY(-4px);
    box-shadow: 0 8px 25px rgba(0, 0, 0, 0.15);
  }

  .product-image {
    width: 100%;
    height: 200px;
    object-fit: cover;
  }

  .product-info {
    padding: 16px;

    .product-name {
      font-size: 16px;
      font-weight: 500;
      margin-bottom: 8px;
      color: #333;
    }

    .product-price {

🚀 部署配置

1. 生产环境配置

typescript
// environments/environment.prod.ts
export const environment = {
  production: true,
  apiUrl: 'https://api.ecommerce-platform.com',
  appName: 'Ecommerce Platform',
  version: '1.0.0'
};

2. 构建配置

json
// angular.json
{
  "projects": {
    "ecommerce-platform": {
      "architect": {
        "build": {
          "builder": "@angular-devkit/build-angular:browser",
          "options": {
            "outputPath": "dist/ecommerce-platform",
            "index": "src/index.html",
            "main": "src/main.ts",
            "polyfills": "src/polyfills.ts",
            "tsConfig": "tsconfig.app.json",
            "assets": [
              "src/favicon.ico",
              "src/assets"
            ],
            "styles": [
              "src/styles.scss"
            ],
            "scripts": [],
            "optimization": true,
            "outputHashing": "all",
            "sourceMap": false,
            "namedChunks": false,
            "aot": true,
            "extractLicenses": true,
            "vendorChunk": false,
            "buildOptimizer": true
          }
        }
      }
    }
  }
}

📱 响应式设计

1. 响应式布局

scss
// responsive-layout.scss
.responsive-grid {
  display: grid;
  gap: 20px;
  grid-template-columns: repeat(auto-fill, minmax(250px, 1fr));

  @media (max-width: 768px) {
    grid-template-columns: repeat(auto-fill, minmax(200px, 1fr));
    gap: 15px;
  }

  @media (max-width: 480px) {
    grid-template-columns: 1fr;
    gap: 10px;
  }
}

.sidebar-layout {
  display: grid;
  grid-template-columns: 250px 1fr;
  gap: 20px;

  @media (max-width: 768px) {
    grid-template-columns: 1fr;
    
    .sidebar {
      order: 2;
    }
    
    .main-content {
      order: 1;
    }
  }
}
