我创建了一个小的工作示例，只需几个步骤就可以将源文件夹复制到另一个目标文件夹(基于shift66使用ncp的答案):

步骤1 -安装ncp模块:

npm install ncp --save

步骤2 -创建copy.js(修改srcPath和destPath变量为你需要的任何变量):

var path = require('path');
var ncp = require('ncp').ncp;

ncp.limit = 16;

var srcPath = path.dirname(require.main.filename); // Current folder
var destPath = '/path/to/destination/folder'; // Any destination folder

console.log('Copying files...');
ncp(srcPath, destPath, function (err) {
  if (err) {
    return console.error(err);
  }
  console.log('Copying files complete.');
});

第三步——跑步

node copy.js

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);
        }
    });
}

打印稿版本

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);
    })
  );
}

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)

从Node v16.7.0开始，可以使用fs。Cp或fs。cpSync函数。

fs.cp(src, dest, {recursive: true});

电流稳定性(在节点v18.7.0中)是实验性的。

有一些模块支持复制文件夹及其内容。最流行的是wrench.js:

// Deep-copy an existing directory
wrench.copyDirSyncRecursive('directory_to_copy', 'location_where_copy_should_end_up');

一个替代方案是node-fs-extra:

fs.copy('/tmp/mydir', '/tmp/mynewdir', function (err) {
  if (err) {
    console.error(err);
  } else {
    console.log("success!");
  }
}); // Copies directory, even if it has subdirectories or files
