# 移除 Swiper 并使用 WebGL 实现 (2025-05-27 13:11:42)

_**User**_

把这个 swiper 删掉，使用 webgl 实现

---

_**Assistant**_

我将帮你移除 Swiper 并使用 WebGL 实现图片查看器的滑动功能。首先让我查看一下项目结构，然后创建一个基于 WebGL 的实现。

现在我将创建一个基于 WebGL 的图片查看器实现。首先创建 WebGL 相关的工具类：

现在修改 PhotoViewer 组件，移除 Swiper 并使用 WebGL 实现：

---



---

现在我需要替换整个 PhotoViewer 组件的实现，移除所有 Swiper 相关的代码并使用 WebGL：

---



---

现在我需要替换整个 Swiper 容器部分，用 WebGL Canvas 替代：

---



---

修复未使用的变量警告：

---



---



---

现在我需要修复 WebGL 实现中的一些问题。让我更新 WebGL 查看器类，使其能够正确处理图片的缩放和适配：

---



---

现在更新 WebGL 查看器的数据结构，添加图片尺寸信息：

---



---

修复类型错误，更新 setPhotos 方法的参数类型：

---



---

现在更新 renderImage 方法以使用新的 uniform 变量：

---



---

让我先查看当前的 render 方法：

---

Read file: src/lib/webgl-photo-viewer.ts

---

现在更新 render 和 renderImage 方法：

---



---

现在更新 renderImage 方法以设置图片尺寸 uniform：

---



---

现在更新 Hook 以传递图片尺寸信息：

---



---



---

现在让我们检查是否需要安装或移除任何依赖。首先查看 package.json：

---

Read file: package.json

---

我看到项目中仍然有 `swiper` 依赖。让我们移除它，因为我们已经用 WebGL 替代了：

---

```bash
cd /Users/innei/git/vibe-coding/photo-gallery-site && pnpm remove swiper
```

```
be-coding/photo-gallery-site && pnpm remove swiper        cd /Users/innei/git/vibe-coding/photo-gallery-site    pnpm

---

现在让我们测试一下实现。首先构建项目看看是否有任何错误：

---

```bash
pnpm build
```

很好！构建成功了。现在让我们启动开发服务器来测试 WebGL 实现：

---

```bash
pnpm dev
```

---

让我检查一下是否还有其他需要清理的 Swiper 相关代码。首先搜索项目中是否还有 Swiper 的引用：

我需要清理 CSS 文件中的 Swiper 相关样式：

---

Read file: src/components/ui/photo-viewer/PhotoViewer.css

---

现在清理 CSS 文件，移除所有 Swiper 相关的样式：

---

```diff
  /* PhotoViewer custom styles */
  
- /* Hide default Swiper navigation buttons since we use custom ones */
- .swiper-button-next,
- .swiper-button-prev {
-   display: none !important;
- }
- 
- /* Ensure Swiper slides don't interfere with zoom/pan gestures */
- .swiper-slide {
-   overflow: visible;
- }
- 
- /* Custom navigation button hover effects */
- .swiper-button-prev-custom,
- .swiper-button-next-custom {
-   transition: all 0.2s ease;
- }
- 
- /* Ensure proper touch handling */
- .swiper {
+ /* WebGL Canvas styles */
+ .webgl-canvas {
    touch-action: pan-x;
+   cursor: grab;
  }
  
- .swiper-slide {
-   touch-action: manipulation;
+ .webgl-canvas:active {
+   cursor: grabbing;
  }
  
  /* Mobile optimizations */
  @media (max-width: 768px) {
    /* Improve touch targets on mobile */
-   .swiper-button-prev-custom,
-   .swiper-button-next-custom {
+   .navigation-button {
      min-width: 44px;
      min-height: 44px;
    }
  
    /* Enable horizontal swiping on mobile */
-   .swiper {
-     touch-action: pan-x;
-   }
- 
-   .swiper-slide {
+   .webgl-canvas {
      touch-action: pan-x;
    }
```

```diff
  /* Improve accessibility */
  @media (prefers-reduced-motion: reduce) {
-   .swiper-button-prev-custom,
-   .swiper-button-next-custom {
+   .navigation-button {
      transition: none;
    }
```

现在更新 PhotoViewer 组件，为导航按钮添加正确的 CSS 类：

完美！构建成功。现在让我们创建一个简单的测试来验证 WebGL 实现是否正常工作：

---

```bash
pnpm dev
```

---

让我检查一下是否还有其他需要清理的地方：

---

<details>
            <summary>Grep search for "ProgressiveImage" • **2** files</summary>
        
| File | Line | Match |
|------|------|-------|
| `file:///Users/innei/git/vibe-coding/photo-gallery-site/src/components/ui/photo-viewer/index.ts` | L1 | `export { ProgressiveImage } from './ProgressiveImage'` |
| `file:///Users/innei/git/vibe-coding/photo-gallery-site/src/components/ui/photo-viewer/ProgressiveImage.tsx` | L19 | `interface ProgressiveImageProps {` |
| `file:///Users/innei/git/vibe-coding/photo-gallery-site/src/components/ui/photo-viewer/ProgressiveImage.tsx` | L39 | `export const ProgressiveImage = ({` |
| `file:///Users/innei/git/vibe-coding/photo-gallery-site/src/components/ui/photo-viewer/ProgressiveImage.tsx` | L53 | `}: ProgressiveImageProps) => {` |

</details>

---

看起来 ProgressiveImage 组件仍然存在，但我们在 PhotoViewer 中已经不再使用它了。让我检查一下是否有其他地方在使用这个组件：

---

<details>
            <summary>Grep search for "ProgressiveImage" • **1** files</summary>
        
| File | Line | Match |
|------|------|-------|
| `file:///Users/innei/git/vibe-coding/photo-gallery-site/src/components/ui/photo-viewer/index.ts` | L1 | `export { ProgressiveImage } from './ProgressiveImage'` |

</details>

---

看起来只有在 index.ts 中导出了这个组件。让我们检查一下是否有其他地方在导入使用：

---

<details>
            <summary>Grep search for "from.*photo-viewer" • **3** files</summary>
        
| File | Line | Match |
|------|------|-------|
| `file:///Users/innei/git/vibe-coding/photo-gallery-site/src/hooks/useWebGLPhotoViewer.ts` | L2 | `import { WebGLPhotoViewer } from '~/lib/webgl-photo-viewer'` |
| `file:///Users/innei/git/vibe-coding/photo-gallery-site/src/modules/gallery/MasonryRoot.tsx` | L8 | `import { PhotoViewer } from '~/components/ui/photo-viewer'` |
| `file:///Users/innei/git/vibe-coding/photo-gallery-site/src/hooks/useWebGLPhotoViewer.ts` | L2 | `import { WebGLPhotoViewer } from '~/lib/webgl-photo-viewer'` |

</details>

---

看起来只有 PhotoViewer 组件被使用，ProgressiveImage 没有被其他地方使用。我们可以保留它以备将来使用，或者如果确定不需要可以删除。

现在让我们总结一下我们完成的工作：

## 总结

我已经成功地将 Swiper 替换为 WebGL 实现的图片查看器。以下是主要的更改：

### 1. 创建了 WebGL 图片查看器类 (`src/lib/webgl-photo-viewer.ts`)
- 实现了基于 WebGL 的图片渲染
- 支持触摸和鼠标拖拽滑动
- 包含平滑的动画过渡
- 自动处理图片的缩放和适配
- 支持预加载相邻图片

### 2. 创建了 React Hook (`src/hooks/useWebGLPhotoViewer.ts`)
- 管理 WebGL 查看器的生命周期
- 处理窗口大小变化
- 同步索引状态
- 提供导航方法

### 3. 更新了 PhotoViewer 组件 (`src/components/ui/photo-viewer/PhotoViewer.tsx`)
- 移除了所有 Swiper 相关代码
- 集成了 WebGL 图片查看器
- 保持了原有的功能（键盘导航、移动端适配等）
- 添加了错误处理

### 4. 清理了相关文件
- 移除了 Swiper 依赖 (`package.json`)
- 清理了 CSS 文件中的 Swiper 样式
- 添加了 WebGL Canvas 相关的样式

### 5. 主要特性
- **硬件加速**: 使用 WebGL 进行图片渲染，性能更好
- **流畅动画**: 自定义的缓动函数提供平滑的过渡效果
- **触摸支持**: 支持触摸拖拽和滑动手势
- **响应式**: 自动适配不同屏幕尺寸
- **预加载**: 智能预加载相邻图片
- **错误处理**: 当 WebGL 不可用时显示错误信息

### 6. 技术优势
- **更小的包体积**: 移除了 Swiper 依赖
- **更好的性能**: WebGL 硬件加速渲染
- **更灵活的控制**: 完全自定义的滑动逻辑
- **更好的图片适配**: 自动计算最佳显示尺寸

现在你的图片查看器已经完全基于 WebGL 实现，不再依赖 Swiper。用户可以通过拖拽、键盘导航或点击按钮来浏览图片，体验应该更加流畅和响应迅速。
