async function copyDir(source: string, destination: string): Promise<any> {
  const directoryEntries = await readdir(source, { withFileTypes: true });
  await mkdir(destination, { recursive: true });

  return Promise.all(
    directoryEntries.map(async (entry) => {
      const sourcePath = path.join(source, entry.name);
      const destinationPath = path.join(destination, entry.name);

      return entry.isDirectory()
        ? copyDir(sourcePath, destinationPath)
        : copyFile(sourcePath, destinationPath);
    })
  );
}

如果你想递归复制源目录的所有内容，那么你需要将递归选项传递为true，并尝试通过fs-extra记录catch以进行同步

因为fs-extra完全替代了fs，所以你不需要导入基本模块

const fs = require('fs-extra');
let sourceDir = '/tmp/src_dir';
let destDir = '/tmp/dest_dir';
try {
  fs.copySync(sourceDir, destDir, { recursive: true })
  console.log('success!')
} catch (err) {
  console.error(err)
}

我是这样做的:

let fs = require('fs');
let path = require('path');

然后:

let filePath = // Your file path

let fileList = []
    var walkSync = function(filePath, filelist)
    {
        let files = fs.readdirSync(filePath);
        filelist = filelist || [];
        files.forEach(function(file)
        {
            if (fs.statSync(path.join(filePath, file)).isDirectory())
            {
                filelist = walkSync(path.join(filePath, file), filelist);
            }
            else
            {
                filelist.push(path.join(filePath, file));
            }
        });

        // Ignore hidden files
        filelist = filelist.filter(item => !(/(^|\/)\.[^\/\.]/g).test(item));

        return filelist;
    };

然后调用该方法:

This.walkSync(filePath, fileList)

这是我个人的做法:

function copyFolderSync(from, to) {
    fs.mkdirSync(to);
    fs.readdirSync(from).forEach(element => {
        if (fs.lstatSync(path.join(from, element)).isFile()) {
            fs.copyFileSync(path.join(from, element), path.join(to, element));
        } else {
            copyFolderSync(path.join(from, element), path.join(to, element));
        }
    });
}

它适用于文件夹和文件。

支持符号链接的:

const path = require("path");
const {
  existsSync,
  mkdirSync,
  readdirSync,
  lstatSync,
  copyFileSync,
  symlinkSync,
  readlinkSync,
} = require("fs");

export function copyFolderSync(src, dest) {
  if (!existsSync(dest)) {
    mkdirSync(dest);
  }

  readdirSync(src).forEach((entry) => {
    const srcPath = path.join(src, entry);
    const destPath = path.join(dest, entry);
    const stat = lstatSync(srcPath);

    if (stat.isFile()) {
      copyFileSync(srcPath, destPath);
    } else if (stat.isDirectory()) {
      copyFolderSync(srcPath, destPath);
    } else if (stat.isSymbolicLink()) {
      symlinkSync(readlinkSync(srcPath), destPath);
    }
  });
}

我写了这个函数用于在目录之间递归地复制(copyFileSync)或移动(renameSync)文件:

// Copy files
copyDirectoryRecursiveSync(sourceDir, targetDir);
// Move files
copyDirectoryRecursiveSync(sourceDir, targetDir, true);


function copyDirectoryRecursiveSync(source, target, move) {
    if (!fs.lstatSync(source).isDirectory())
        return;

    var operation = move ? fs.renameSync : fs.copyFileSync;
    fs.readdirSync(source).forEach(function (itemName) {
        var sourcePath = path.join(source, itemName);
        var targetPath = path.join(target, itemName);

        if (fs.lstatSync(sourcePath).isDirectory()) {
            fs.mkdirSync(targetPath);
            copyDirectoryRecursiveSync(sourcePath, targetPath);
        }
        else {
            operation(sourcePath, targetPath);
        }
    });
}
