我试图使用Node.js获取目录中所有文件的名称列表。我希望输出文件名数组。我该怎么做?
当前回答
我通常使用:FS Extra。
const fileNameArray = Fse.readdir('/some/path');
结果:
[
"b7c8a93c-45b3-4de8-b9b5-a0bf28fb986e.jpg",
"daeb1c5b-809f-4434-8fd9-410140789933.jpg"
]

如果有人:
只想列出项目本地子文件夹中的文件名(不包括目录)
✅ 无其他依赖项✅ 1功能✅ 规格化路径(Unix与Windows)
const fs = require("fs");
const path = require("path");
/**
* @param {string} relativeName "resources/foo/goo"
* @return {string[]}
*/
const listFileNames = (relativeName) => {
try {
const folderPath = path.join(process.cwd(), ...relativeName.split("/"));
return fs
.readdirSync(folderPath, { withFileTypes: true })
.filter((dirent) => dirent.isFile())
.map((dirent) => dirent.name.split(".")[0]);
} catch (err) {
// ...
}
};
README.md
package.json
resources
|-- countries
|-- usa.yaml
|-- japan.yaml
|-- gb.yaml
|-- provinces
|-- .........
listFileNames("resources/countries") #=> ["usa", "japan", "gb"]
这是一个异步递归版本。
function ( path, callback){
// the callback gets ( err, files) where files is an array of file names
if( typeof callback !== 'function' ) return
var
result = []
, files = [ path.replace( /\/\s*$/, '' ) ]
function traverseFiles (){
if( files.length ) {
var name = files.shift()
fs.stat(name, function( err, stats){
if( err ){
if( err.errno == 34 ) traverseFiles()
// in case there's broken symbolic links or a bad path
// skip file instead of sending error
else callback(err)
}
else if ( stats.isDirectory() ) fs.readdir( name, function( err, files2 ){
if( err ) callback(err)
else {
files = files2
.map( function( file ){ return name + '/' + file } )
.concat( files )
traverseFiles()
}
})
else{
result.push(name)
traverseFiles()
}
})
}
else callback( null, result )
}
traverseFiles()
}
我的单行代码:
const fs = require("fs")
const path = 'somePath/'
const filesArray = fs.readdirSync(path).filter(file => fs.lstatSync(path+file).isFile())
使用npm列表内容模块。它读取给定目录的内容和子内容,并返回文件和文件夹路径列表。
const list = require('list-contents');
list("./dist",(o)=>{
if(o.error) throw o.error;
console.log('Folders: ', o.dirs);
console.log('Files: ', o.files);
});
试试这个,它对我有用
import fs from "fs/promises";
const path = "path/to/folder";
export const readDir = async function readDir(path) {
const files = await fs.readdir(path);
// array of file names
console.log(files);
}
