前端项目优化-清理大量废弃的图片资源

有这样一个场景:当我们的项目迭代了很多次的版本，每次版本迭代的开发周期很短、很急就导致你没有办法去优化之前的代码。有很多的垃圾代码和图片资源被遗留到最后，这就使得你的项目包巨大，屎山代码一堆，这个时候你打算怎么办？人工一个一个去查找哪些图片是没有用到然后手动删除吗？ 这个难度我想应该不言而喻。

1.首先我们要删除(这一步得手动操作，难度不大)没有用到的.vue、js、html、ts文件，因为npm run build打包的时候，在你的.vue、js、html、ts文件中引用到了图片的话，这些图片就会被打包进去。如果你的文件中没有引用到，即使你的图片放在了assets/images目录下它也不会被打包进去，因为没有引用。（这一点尤其重要！！！！！）

2.删除了不用的文件之后，接下来就是删除掉不用的图片。这个就得node结合js脚本来执行了。大概的思路就是：遍历你项目的所有.vue', '.ts', '.js', '.tsx', '.jsx', '.html'文件，然后和你assets/images下面的所有图片对比路径。 如果没有匹配上的话就说明当前图片没有在项目中用到。下面是代码,在你的根目录运行node --max-old-space-size=8192 cleanfile.js

//cleanfile.js

import fs from 'fs';
import path from 'path';
import { fileURLToPath } from 'url';

// ES 模块中获取 __dirname
const __filename = fileURLToPath(import.meta.url);
const __dirname = path.dirname(__filename);

// 配置路径
const IMAGES_DIR = path.join(__dirname, 'src/assets/images');
const SRC_DIR = path.join(__dirname, 'src');
const EXTENSIONS_TO_SCAN = ['.vue', '.ts', '.js', '.tsx', '.jsx', '.html'];

// 递归获取所有图片文件
function getAllImages(dir, fileList = []) {
  if (!fs.existsSync(dir)) {
    console.log(`⚠️  目录不存在: ${dir}`);
    return fileList;
  }
  
  const files = fs.readdirSync(dir);
  
  files.forEach(file => {
    const filePath = path.join(dir, file);
    const stat = fs.statSync(filePath);
    
    if (stat.isDirectory()) {
      getAllImages(filePath, fileList);
    } else if (/\.(png|jpg|jpeg|gif|svg|webp|ico)$/i.test(file)) {
      fileList.push(filePath);
    }
  });

3. 代码执行完之后会生成一个unused-images-report报告，列出哪些图片没有在项目中用到

4. 现在已经知道哪些图片没有用到，接下来删除这些图片就好了。也是node结合js脚本，代码如下。在你的项目根目录中运行 node clean_images.js，运行成功之后就清理掉项目中的多余图片资源了。

// clean_images.js
// 替换顶部的 require() 语句
import fs from 'fs'; // 使用异步版本，并配合 await
import path from 'path';

// --- 待删除的图片文件路径列表 ---
// 请将你的“未使用的图片列表”中的路径粘贴到下面的数组中。
// 注意：路径分隔符在 Windows 和 Node.js/Linux 中可能需要统一。
// 这里的路径已经是 D:\front\workProjects\研发云\zjwxm\... 的形式，
// 在大多数现代 Node.js 环境中（尤其是搭配 path.resolve），可以直接使用。

总结：其实你npm run build最终打包的大小，只和你文件资源是否引用有直接关系。 你没有引用到的图片资源是不会被打包进去的，即使你放在assets/images下面，但是你的项目中没有引用到，就不会被打包进去。
