1. 安装依赖

npm install archiver --save-dev

2. 准备compress.js文件

const fs = require('fs');
const archiver = require('archiver');const sourceDir = './dist';  //替换为你的文件夹路径
const outputZip = './dist.zip';console.log(`开始压缩`);
const output = fs.createWriteStream(outputZip);
const archive = archiver('zip', { zlib: { level: 9 } });output.on('close', () => {console.log(`压缩完成: ${archive.pointer()} 字节`);
});archive.pipe(output);
archive.directory(sourceDir, true);//true则保留顶级目录，false则不保留
archive.finalize();

3. 在package.json中调用compress.js

在build命令后面，添加并执行一个postbuild命令。

  "scripts": {"serve": "vue-cli-service serve","build": "vue-cli-service build","postbuild": "node compress.js"},

于是，当运行npm run build后，会先生成打包文件夹，再基于该文件夹生成zip压缩包。
