复制文件夹

js
const fs = require('fs');
const path = require('path');
/**
 * 复制目录
 * @param {string} originDir 源目录
 * @param {string} remoteDir 目标目录
 */

function copyDir(originDir, remoteDir) {
  if (!fs.existsSync(remoteDir)) {
  // recursive:递归
    fs.mkdirSync(remoteDir, { recursive: true });
  }
  // 转成dirent对象数组，否则只有[名称]数组
  let files = fs.readdirSync(originDir, { withFileTypes: true });
  console.log('print ~ copyDir ~ files:', files);
  files.forEach((file) => {
    if (file.isDirectory()) {
      copyDir(
        path.resolve(originDir, file.name),
        path.resolve(remoteDir, file.name),
      );
    } else {
      fs.copyFileSync(
        path.resolve(originDir, file.name),
        path.resolve(remoteDir, file.name),
      );
    }
  });
  console.log('print ~ copyDir ~ files:', files);
}

压缩目录

js
const fs = require('fs');
const path = require('path');
const archiver = require('archiver');

/**
 * 压缩目录
 * @param {string} sourceDir 源目录
 * @param {string} outPath 输出路径
 */
function zipDir(sourceDir, outPath) {
  return new Promise((resolve, reject) => {
    const output = fs.createWriteStream(outPath);
    const archive = archiver('zip', {
      zlib: { level: 9 }, // 压缩级别 1-9
    });

    output.on('close', () => {
      console.log(`压缩完成：${archive.pointer()} bytes`);
      resolve();
    });
    archive.on('error', (err) => reject(err));
    archive.pipe(output);
    // 把整个目录加入 zip
    archive.directory(sourceDir, false);
    archive.finalize();
  });
}
