this.loadImage(img); this.observer.unobserve(img); } }); }, { rootMargin: 50px 0px, threshold: 0.1, } ); } private loadImage(img: HTMLImageElement) { const src img.getAttribute(data-src); if (!src || this.loadedImages.has(src)) return; const image new Image(); image.onload () { img.src src; img.classList.add(loaded); this.loadedImages.add(src); }; image.onerror () { console.warn(Failed to load image: ${src}); img.classList.add(error); }; image.src src; } observe(img: HTMLImageElement) { this.observer.observe(img); } unobserve(img: HTMLImageElement) { this.observer.unobserve(img); } disconnect() { this.observer.disconnect(); } } // 单例模式 export const imageLoader new ImageLoader();7.2 自定义Hook优化// src/hooks/useImagePreload.ts import { useEffect, useState } from react; export const useImagePreload (imageUrls: string[]) { const [loadedCount, setLoadedCount] useState(0); const [errorUrls, setErrorUrls] useStatestring[]([]); useEffect(() { let mounted true; const loadedUrls: string[] []; const errors: string[] []; const loadImage (url: string): Promisevoid { return new Promise((resolve, reject) { const img new Image(); img.onload () { if (mounted) { loadedUrls.push(url); setLoadedCount(loadedUrls.length); } resolve(); }; img.onerror () { if (mounted) { errors.push(url); setErrorUrls([...errors]); } reject(new Error(Failed to load image: ${url})); }; img.src url; }); }; const loadAllImages async () { try { await Promise.allSettled(imageUrls.map(loadImage)); } catch (error) { console.warn(Some images failed to load:, error); } }; loadAllImages(); return () { mounted false; }; }, [imageUrls]); const progress imageUrls.length 0 ? loadedCount / imageUrls.length : 0; const allLoaded loadedCount imageUrls.length; return { loadedCount, errorUrls, progress, allLoaded, }; };8. 数据模拟与测试8.1 模拟数据生成// src/data/mockData.ts import { Swimsuit } from ../types/swimsuit; export const generateMockSwimsuits (): Swimsuit[] { return [ { id: 1, name: 经典红色连体泳装, price: 299, description: 采用高品质面料舒适透气适合各种水上活动, inStock: true, colors: [ { id: red, name: 经典红, value: #ff3b30, available: true }, { id: black, name: 神秘黑, value: #000000, available: true }, { id: blue, name: 海洋蓝, value: #007aff, available: false }, ], sizes: [ { id: s, label: S, available: true }, { id: m, label: M, available: true }, { id: l, label: L, available: false }, { id: xl, label: XL, available: true }, ], images: { main: /images/swimsuit-red-main.jpg, thumbnails: [ /images/swimsuit-red-thumb1.jpg, /images/swimsuit-red-thumb2.jpg, ], angles: [ /images/swimsuit-red-angle1.jpg, /images/swimsuit-red-angle2.jpg, /images/swimsuit-red-angle3.jpg, /images/swimsuit-red-angle4.jpg, ], }, }, // 更多模拟数据... ]; };8.2 组件测试示例// src/components/__tests__/SwimsuitGallery.test.tsx import { render, screen, fireEvent } from testing-library/react; import SwimsuitGallery from ../SwimsuitGallery/SwimsuitGallery; import { Swimsuit } from ../../types/swimsuit; const mockSwimsuits: Swimsuit[] [ { id: 1, name: 测试泳装, price: 199, description: 测试描述, inStock: true, colors: [{ id: red, name: 红色, value: #ff0000, available: true }], sizes: [{ id: m, label: M, available: true }], images: { main: test.jpg, thumbnails: [thumb1.jpg], angles: [angle1.jpg], }, }, ]; describe(SwimsuitGallery, () { it(应该正确渲染泳装列表, () { const mockOnSelect jest.fn(); render(SwimsuitGallery swimsuits{mockSwimsuits} onSwimsuitSelect{mockOnSelect} /); expect(screen.getByText(测试泳装)).toBeInTheDocument(); expect(screen.getByText(¥199)).toBeInTheDocument(); }); it(应该处理搜索功能, () { const mockOnSelect jest.fn(); render(SwimsuitGallery swimsuits{mockSwimsuits} onSwimsuitSelect{mockOnSelect} /); const searchInput screen.getByPlaceholderText(搜索泳装...); fireEvent.change(searchInput, { target: { value: 不存在的泳装 } }); expect(screen.queryByText(测试泳装)).not.toBeInTheDocument(); }); });9. 部署与生产环境配置9.1 Vite生产配置// vite.config.js import { defineConfig } from vite; import react from vitejs/plugin-react; export default defineConfig({ plugins: [react()], build: { outDir: dist, sourcemap: true, rollupOptions: { output: { manualChunks: { vendor: [react, react-dom], utils: [zustand, lodash-es], }, }, }, }, server: { port: 3000, open: true, }, preview: { port: 4173, }, });9.2 环境变量配置// .env.production VITE_API_BASE_URLhttps://api.example.com VITE_CDN_BASE_URLhttps://cdn.example.com VITE_APP_VERSION1.0.0 // .env.development VITE_API_BASE_URLhttp://localhost:3001 VITE_CDN_BASE_URLhttp://localhost:3000 VITE_APP_VERSION1.0.0-dev10. 常见问题与解决方案10.1 图片加载性能问题问题现象页面加载时图片显示缓慢影响用户体验解决方案实现图片懒加载技术使用WebP格式图片减小文件大小配置合适的CDN加速添加图片加载骨架屏// 图片优化工具函数 export const optimizeImageUrl (url: string, width: number, quality 80): string { if (url.includes(?)) { return ${url}w${width}q${quality}formatwebp; } return ${url}?w${width}q${quality}formatwebp; };10.2 移动端适配问题问题现象在移动设备上布局错乱交互不流畅解决方案使用rem单位进行响应式布局添加触摸事件支持优化移动端手势操作测试不同屏幕尺寸的显示效果10.3 状态管理复杂性问题问题现象组件间状态传递复杂难以维护解决方案使用Zustand进行集中状态管理将状态按功能模块拆分使用自定义Hook封装复杂逻辑添加类型安全保证通过以上完整的实现方案开发者可以构建出功能丰富、性能优异、用户体验良好的泳装展示系统。这个项目不仅涵盖了现代前端开发的核心技术栈还提供了完整的工程化实践方案适合作为前端技能提升的重要练习项目。
