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

由于我只是构建一个简单的Node.js脚本，我不希望脚本的用户需要导入一堆外部模块和依赖项，所以我开始思考，并从Bash shell中搜索运行命令。

这个Node.js代码片段递归地复制了一个名为node-webkit的文件夹。应用程序到一个名为build的文件夹:

child = exec("cp -r node-webkit.app build", function(error, stdout, stderr) {
    sys.print("stdout: " + stdout);
    sys.print("stderr: " + stderr);
    if(error !== null) {
        console.log("exec error: " + error);
    } else {

    }
});

感谢dzone的兰斯·波拉德让我开始。

上面的代码片段仅限于基于unix的平台，如macOS和Linux，但类似的技术也适用于Windows。

下面是一个递归复制目录及其内容到另一个目录的函数:

const fs = require("fs")
const path = require("path")

/**
 * Look ma, it's cp -R.
 * @param {string} src  The path to the thing to copy.
 * @param {string} dest The path to the new copy.
 */
var copyRecursiveSync = function(src, dest) {
  var exists = fs.existsSync(src);
  var stats = exists && fs.statSync(src);
  var isDirectory = exists && stats.isDirectory();
  if (isDirectory) {
    fs.mkdirSync(dest);
    fs.readdirSync(src).forEach(function(childItemName) {
      copyRecursiveSync(path.join(src, childItemName),
                        path.join(dest, childItemName));
    });
  } else {
    fs.copyFileSync(src, dest);
  }
};

这是我解决这个问题的方法，没有任何额外的模块。只使用内置的fs和path模块。

注意:这使用fs的读/写函数，所以它不复制任何元数据(创建时间等)。从Node.js 8.5开始，有一个copyFileSync函数可用，它调用操作系统复制函数，因此也复制元数据。我还没有测试它们，但它应该可以替换它们。(见https://nodejs.org/api/fs.html fs_fs_copyfilesync_src_dest_flags)

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

function copyFileSync( source, target ) {

    var targetFile = target;

    // If target is a directory, a new file with the same name will be created
    if ( fs.existsSync( target ) ) {
        if ( fs.lstatSync( target ).isDirectory() ) {
            targetFile = path.join( target, path.basename( source ) );
        }
    }

    fs.writeFileSync(targetFile, fs.readFileSync(source));
}

function copyFolderRecursiveSync( source, target ) {
    var files = [];

    // Check if folder needs to be created or integrated
    var targetFolder = path.join( target, path.basename( source ) );
    if ( !fs.existsSync( targetFolder ) ) {
        fs.mkdirSync( targetFolder );
    }

    // Copy
    if ( fs.lstatSync( source ).isDirectory() ) {
        files = fs.readdirSync( source );
        files.forEach( function ( file ) {
            var curSource = path.join( source, file );
            if ( fs.lstatSync( curSource ).isDirectory() ) {
                copyFolderRecursiveSync( curSource, targetFolder );
            } else {
                copyFileSync( curSource, targetFolder );
            }
        } );
    }
}

这段代码可以很好地工作，递归地将任何文件夹复制到任何位置。但它只适用于Windows。

var child = require("child_process");
function copySync(from, to){
    from = from.replace(/\//gim, "\\");
    to = to.replace(/\//gim, "\\");
    child.exec("xcopy /y /q \"" + from + "\\*\" \"" + to + "\\\"");
}

它非常适合我的基于文本的游戏去创造新玩家。

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

对于Linux/Unix操作系统，可以使用shell语法

const shell = require('child_process').execSync;

const src = `/path/src`;
const dist = `/path/dist`;

shell(`mkdir -p ${dist}`);
shell(`cp -r ${src}/* ${dist}`);

就是这样!

fs-extra模块工作起来很有魅力。

安装fs-extra:

$ npm install fs-extra

下面是将源目录复制到目标目录的程序。

// Include the fs-extra package
var fs = require("fs-extra");

var source = 'folderA'
var destination = 'folderB'

// Copy the source folder to the destination
fs.copy(source, destination, function (err) {
    if (err){
        console.log('An error occurred while copying the folder.')
        return console.error(err)
    }
    console.log('Copy completed!')
});

是的，ncp很酷…

你可能想要/应该承诺它的功能，让它超级酷。当你这样做的时候，把它添加到一个工具文件中以重复使用它。

下面是一个工作版本，它是异步的，并使用承诺。

文件index.js

const {copyFolder} = require('./tools/');

return copyFolder(
    yourSourcePath,
    yourDestinationPath
)
.then(() => {
    console.log('-> Backup completed.')
}) .catch((err) => {
    console.log("-> [ERR] Could not copy the folder: ", err);
})

文件tools.js

const ncp = require("ncp");

/**
 * Promise Version of ncp.ncp()
 *
 * This function promisifies ncp.ncp().
 * We take the asynchronous function ncp.ncp() with
 * callback semantics and derive from it a new function with
 * promise semantics.
 */
ncp.ncpAsync = function (sourcePath, destinationPath) {
  return new Promise(function (resolve, reject) {
      try {
          ncp.ncp(sourcePath, destinationPath, function(err){
              if (err) reject(err); else resolve();
          });
      } catch (err) {
          reject(err);
      }
  });
};

/**
 * Utility function to copy folders asynchronously using
 * the Promise returned by ncp.ncp().
 */
const copyFolder = (sourcePath, destinationPath) => {
    return ncp.ncpAsync(sourcePath, destinationPath, function (err) {
        if (err) {
            return console.error(err);
        }
    });
}
module.exports.copyFolder = copyFolder;

Mallikarjun M，谢谢!

fs-extra做了这件事，如果你不提供一个回调，它甚至可以返回一个承诺!:)

const path = require('path')
const fs = require('fs-extra')

let source = path.resolve( __dirname, 'folderA')
let destination = path.resolve( __dirname, 'folderB')

fs.copy(source, destination)
  .then(() => console.log('Copy completed!'))
  .catch( err => {
    console.log('An error occurred while copying the folder.')
    return console.error(err)
  })

解决这个问题最简单的方法是只使用'fs'和'Path'模块和一些逻辑…

如果你只是想设置版本号，根文件夹中的所有文件都复制新名称，即" var v = '您的目录名'"

在文件名的前缀中添加带有文件名的内容。

var fs = require('fs-extra');
var path = require('path');

var c = 0;
var i = 0;
var v = "1.0.2";
var copyCounter = 0;
var directoryCounter = 0;
var directoryMakerCounter = 0;
var recursionCounter = -1;
var Flag = false;
var directoryPath = [];
var directoryName = [];
var directoryFileName = [];
var fileName;
var directoryNameStorer;
var dc = 0;
var route;

if (!fs.existsSync(v)) {
    fs.mkdirSync(v);
}

var basePath = path.join(__dirname, v);


function walk(dir) {

    fs.readdir(dir, function(err, items) {

        items.forEach(function(file) {

            file = path.resolve(dir, file);

            fs.stat(file, function(err, stat) {

                if(stat && stat.isDirectory()) {
                    directoryNameStorer = path.basename(file);
                    route = file;
                    route = route.replace("gd", v);

                    directoryFileName[directoryCounter] = route;
                    directoryPath[directoryCounter] = file;
                    directoryName[directoryCounter] = directoryNameStorer;

                    directoryCounter++;
                    dc++;

                    if (!fs.existsSync(basePath + "/" + directoryName[directoryMakerCounter])) {
                        fs.mkdirSync(directoryFileName[directoryMakerCounter]);
                        directoryMakerCounter++;
                    }
                }
                else {
                    fileName = path.basename(file);
                    if(recursionCounter >= 0) {
                        fs.copyFileSync(file, directoryFileName[recursionCounter] + "/" + v + "_" + fileName, err => {
                            if(err) return console.error(err);
                        });
                        copyCounter++;
                    }
                    else {
                        fs.copyFileSync(file, v + "/" + v + "_" + fileName, err => {
                            if(err) return console.error(err);
                        });
                        copyCounter++;
                    }
                }
                if(copyCounter + dc == items.length && directoryCounter > 0 && recursionCounter < directoryMakerCounter-1) {
                    console.log("COPY COUNTER:             " + copyCounter);
                    console.log("DC COUNTER:               " + dc);
                    recursionCounter++;
                    dc = 0;
                    copyCounter = 0;
                    console.log("ITEM DOT LENGTH:          " + items.length);
                    console.log("RECURSION COUNTER:        " + recursionCounter);
                    console.log("DIRECOTRY MAKER COUNTER:  " + directoryMakerCounter);
                    console.log(": START RECURSION:        " + directoryPath[recursionCounter]);
                    walk(directoryPath[recursionCounter]); //recursive call to copy sub-folder
                }
            })
        })
    });
}

walk('./gd', function(err, data) { // Just pass the root directory which you want to copy
    if(err)
        throw err;
    console.log("done");
})

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。

这在Node.js 10中非常简单:

const Path = require('path');
const FSP = require('fs').promises;

async function copyDir(src,dest) {
    const entries = await FSP.readdir(src, {withFileTypes: true});
    await FSP.mkdir(dest);
    for(let entry of entries) {
        const srcPath = Path.join(src, entry.name);
        const destPath = Path.join(dest, entry.name);
        if(entry.isDirectory()) {
            await copyDir(srcPath, destPath);
        } else {
            await FSP.copyFile(srcPath, destPath);
        }
    }
}

这里假设dest不存在。

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)

我尝试了fs-extra和copy-dir来递归地复制文件夹。但我希望它能

正常工作(copy-dir抛出一个不合理的错误) 在过滤器中提供两个参数:filepath和filetype (fs-extra不告诉文件类型) 有从目录到子目录的检查和从目录到文件的检查吗

所以我自己写了:

// Node.js module for Node.js 8.6+
var path = require("path");
var fs = require("fs");

function copyDirSync(src, dest, options) {
  var srcPath = path.resolve(src);
  var destPath = path.resolve(dest);
  if(path.relative(srcPath, destPath).charAt(0) != ".")
    throw new Error("dest path must be out of src path");
  var settings = Object.assign(Object.create(copyDirSync.options), options);
  copyDirSync0(srcPath, destPath, settings);
  function copyDirSync0(srcPath, destPath, settings) {
    var files = fs.readdirSync(srcPath);
    if (!fs.existsSync(destPath)) {
      fs.mkdirSync(destPath);
    }else if(!fs.lstatSync(destPath).isDirectory()) {
      if(settings.overwrite)
        throw new Error(`Cannot overwrite non-directory '${destPath}' with directory '${srcPath}'.`);
      return;
    }
    files.forEach(function(filename) {
      var childSrcPath = path.join(srcPath, filename);
      var childDestPath = path.join(destPath, filename);
      var type = fs.lstatSync(childSrcPath).isDirectory() ? "directory" : "file";
      if(!settings.filter(childSrcPath, type))
        return;
      if (type == "directory") {
        copyDirSync0(childSrcPath, childDestPath, settings);
      } else {
        fs.copyFileSync(childSrcPath, childDestPath, settings.overwrite ? 0 : fs.constants.COPYFILE_EXCL);
        if(!settings.preserveFileDate)
          fs.futimesSync(childDestPath, Date.now(), Date.now());
      }
    });
  }
}
copyDirSync.options = {
  overwrite: true,
  preserveFileDate: true,
  filter: function(filepath, type) {
    return true;
  }
};

还有一个类似的函数mkdirs，它是mkdirp的替代:

function mkdirsSync(dest) {
  var destPath = path.resolve(dest);
  mkdirsSync0(destPath);
  function mkdirsSync0(destPath) {
    var parentPath = path.dirname(destPath);
    if(parentPath == destPath)
      throw new Error(`cannot mkdir ${destPath}, invalid root`);
    if (!fs.existsSync(destPath)) {
      mkdirsSync0(parentPath);
      fs.mkdirSync(destPath);
    }else if(!fs.lstatSync(destPath).isDirectory()) {
      throw new Error(`cannot mkdir ${destPath}, a file already exists there`);
    }
  }
}

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);
        }
    });
}

我知道这里已经有很多答案了，但是没有一个答案是简单的。

关于fs-exra官方文档，您可以非常轻松地完成。

const fs = require('fs-extra')

// Copy file
fs.copySync('/tmp/myfile', '/tmp/mynewfile')

// Copy directory, even if it has subdirectories or files
fs.copySync('/tmp/mydir', '/tmp/mynewdir')

如果你在Linux上，性能不是问题，你可以使用child_process模块中的exec函数来执行一个Bash命令:

const { exec } = require('child_process');
exec('cp -r source dest', (error, stdout, stderr) => {...});

在某些情况下，我发现这个解决方案比下载整个模块甚至使用fs模块更简洁。

挑选包裹时要小心。有些包(如copy-dir)不支持复制长度超过0X1FFFFFE8个字符(约537 MB)的大文件。

它会抛出一些错误，比如:

buffer.js:630 Uncaught Error:不能创建大于0x1fffffe8字符的字符串

在我的一个项目中，我就经历过类似的事情。最终，我不得不改变我正在使用的包并调整大量代码。我想说，这不是一个很愉快的经历。

如果需要多个源副本和多个目标副本，您可以使用better-copy并编写如下内容:

// Copy from multiple source into a directory
bCopy(['/path/to/your/folder1', '/path/to/some/file.txt'], '/path/to/destination/folder');

甚至:

// Copy from multiple source into multiple destination
bCopy(['/path/to/your/folder1', '/path/to/some/file.txt'], ['/path/to/destination/folder', '/path/to/another/folder']);

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);
    }
  });
}

看起来ncp和扳手都不再维护了。可能最好的选择是使用fs-extra

扳手的开发人员指导用户使用fs-extra，因为他已经弃用了他的库

copySync和moveSync都将复制和移动文件夹，即使他们有文件或子文件夹，你可以很容易地移动或复制文件使用它

const fse = require('fs-extra');

const srcDir = `path/to/file`;
const destDir = `path/to/destination/directory`;
                                 
// To copy a folder or file, select overwrite accordingly
try {
  fs.copySync(srcDir, destDir, { overwrite: true|false })
  console.log('success!')
} catch (err) {
  console.error(err)
}

OR

// To Move a folder or file, select overwrite accordingly
try {
  fs.moveSync(srcDir, destDir, { overwrite: true|false })
  console.log('success!')
} catch (err) {
  console.error(err)
}

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)
}

使用 shelljs

npm i -D shelljs

const bash = require('shelljs');
bash.cp("-rf", "/path/to/source/folder", "/path/to/destination/folder");

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。

目前最上面的答案可以大大简化。

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

function recursiveCopySync(source, target) {
  if (fs.lstatSync(source).isDirectory()) {
    if (!fs.existsSync(target)) {
      fs.mkdirSync(target);
    }
    let files = fs.readdirSync(source);
    files.forEach((file) => {
      recursiveCopySync(path.join(source, file), path.join(target, file));
    });
  } else {
    if (fs.existsSync(source)) {
      fs.writeFileSync(target, fs.readFileSync(source));
    }
  }
}

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);
    })
  );
}

从Node v16.7.0开始:

import { cp } from 'fs/promises';
await cp(
  new URL('../path/to/src/', import.meta.url),
  new URL('../path/to/dest/', import.meta.url), {
    recursive: true,
  }
);

注意使用递归:true。这可以防止ERR_FS_EISDIR错误。

阅读更多关于节点文件系统的文档

对于没有fs的旧节点版本。cp，我在紧要关头使用这个来避免需要第三方库:

const fs = require("fs").promises;
const path = require("path");

const cp = async (src, dest) => {
  const lstat = await fs.lstat(src).catch(err => false);

  if (!lstat) {
    return;
  }
  else if (await lstat.isFile()) {
    await fs.copyFile(src, dest);
  }
  else if (await lstat.isDirectory()) {
    await fs.mkdir(dest).catch(err => {});

    for (const f of await fs.readdir(src)) {

// sample usage
(async () => {
  const src = "foo";
  const dst = "bar";

  for (const f of await fs.readdir(src)) {

  }
})();

相对于现有答案的优势(或区别):

异步 忽略符号链接 如果目录已经存在，则不抛出(如果不需要，则不捕获mkdir抛出) 相当简洁的

这可能是一个可能的解决方案使用异步生成器函数和迭代等待循环。这个解决方案包括过滤掉一些目录的可能性，将它们作为可选的第三个数组参数传递。

import path from 'path';
import { readdir, copy } from 'fs-extra';

async function* getFilesRecursive(srcDir: string, excludedDir?: PathLike[]): AsyncGenerator<string> {
  const directoryEntries: Dirent[] = await readdir(srcDir, { withFileTypes: true });
  if (!directoryEntries.length) yield srcDir; // If the directory is empty, return the directory path.
  for (const entry of directoryEntries) {
    const fileName = entry.name;
      const sourcePath = resolvePath(`${srcDir}/${fileName}`);
      if (entry.isDirectory()) {
        if (!excludedDir?.includes(sourcePath)) {
          yield* getFilesRecursive(sourcePath, excludedDir);
        }
      } else {
        yield sourcePath;
      }
  }
}

然后:

for await (const filePath of getFilesRecursive(path, ['dir1', 'dir2'])) {
   await copy(filePath, filePath.replace(path, path2));
}

内联版本

node -e "const fs=require('fs');const p=require('path');function copy(src, dest) {if (!fs.existsSync(src)) {return;} if (fs.statSync(src).isFile()) {fs.copyFileSync(src, dest);}else{fs.mkdirSync(dest, {recursive: true});fs.readdirSync(src).forEach(f=>copy(p.join(src, f), p.join(dest, f)));}}const args=Array.from(process.argv); copy(args[args.length-2], args[args.length-1]);" dist temp\dest

或者节点16.x+

node -e "const fs=require('fs');const args=Array.from(process.argv); fs.cpSync(args[args.length-2], args[args.length-1], {recursive: true});" 

在“节点14.20.0”上测试，但假设它在节点10.x上工作?

如果在包中使用，请务必转义引号。json脚本

package.json:

  "scripts": {
    "rmrf": "node -e \"const fs=require('fs/promises');const args=Array.from(process.argv); Promise.allSettled(args.map(a => fs.rm(a, { recursive: true, force: true })));\"",
    "cp": "node -e \"const fs=require('fs');const args=Array.from(process.argv);if (args.length>2){ fs.cpSync(args[args.length-2], args[args.length-1], {recursive: true});}else{console.log('args missing', args);}\""
    "copy": "node -e \"const fs=require('fs');const p=require('path');function copy(src, dest) {if (!fs.existsSync(src)) {return;} if (fs.statSync(src).isFile()) {fs.copyFileSync(src, dest);}else{fs.mkdirSync(dest, {recursive: true});fs.readdirSync(src).forEach(f=>copy(p.join(src, f), p.join(dest, f)));}}const args=Array.from(process.argv);if (args.length>2){copy(args[args.length-2], args[args.length-1]);}else{console.log('args missing', args);}\"",
    "mkdir": "node -e \"const fs=require('fs');const args=Array.from(process.argv);fs.mkdirSync(args[args.length-1],{recursive:true});\"",
    "clean": "npm run rmrf -- temp && npm run mkdir -- temp && npm run copy -- dist temp"
  }

注:RMRF脚本需要14.20节点。X还是12.20.x?

奖金:

deno eval "import { existsSync, mkdirSync, copyFileSync, readdirSync, statSync } from 'node:fs';import { join } from 'node:path';function copy(src, dest) {if (!existsSync(src)) {return;} if (statSync(src).isFile()) {copyFileSync(src, dest);}else{mkdirSync(dest, {recursive: true});readdirSync(src).forEach(f=>copy(join(src, f), join(dest, f)));}}const args=Array.from(Deno.args);copy(args[0], args[1]);" dist temp\dest -- --allow-read --allow-write
