是否有一种更简单的方法来复制文件夹及其所有内容,而无需手动执行一系列的fs。readir, fs。readfile, fs。writefile递归?
我只是想知道我是否错过了一个函数,理想情况下是这样工作的:
fs.copy("/path/to/source/folder", "/path/to/destination/folder");
关于这个历史问题。注意fs。Cp和fs。cpSync可以递归复制文件夹,在Node v16+中可用

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)
其他回答
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!')
});

示例:Node.js教程- Node.js复制文件夹
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);
}
});
}
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。
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 );
}
} );
}
}
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?
