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
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);
});

IMO完成此类任务最方便的方法是使用glob工具。这是node.js的glob包
npm install glob
然后使用通配符匹配文件名(示例取自软件包的网站)
var glob = require("glob")
// options is optional
glob("**/*.js", options, function (er, files) {
// files is an array of filenames.
// If the `nonull` option is set, and nothing
// was found, then files is ["**/*.js"]
// er is an error object or null.
})
如果您计划使用globby,这里有一个示例来查找当前文件夹下的任何xml文件
var globby = require('globby');
const paths = await globby("**/*.xml");
获取所有分区中的文件
const fs=require('fs');
function getFiles (dir, files_){
files_ = files_ || [];
var files = fs.readdirSync(dir);
for (var i in files){
var name = dir + '/' + files[i];
if (fs.statSync(name).isDirectory()){
getFiles(name, files_);
} else {
files_.push(name);
}
}
return files_;
}
console.log(getFiles('path/to/dir'))
这是一个TypeScript,可选递归,可选错误日志和异步解决方案。可以为要查找的文件名指定正则表达式。
我使用了fs extra,因为这是对fs的一个简单的超集改进。
import * as FsExtra from 'fs-extra'
/**
* Finds files in the folder that match filePattern, optionally passing back errors .
* If folderDepth isn't specified, only the first level is searched. Otherwise anything up
* to Infinity is supported.
*
* @static
* @param {string} folder The folder to start in.
* @param {string} [filePattern='.*'] A regular expression of the files you want to find.
* @param {(Error[] | undefined)} [errors=undefined]
* @param {number} [folderDepth=0]
* @returns {Promise<string[]>}
* @memberof FileHelper
*/
public static async findFiles(
folder: string,
filePattern: string = '.*',
errors: Error[] | undefined = undefined,
folderDepth: number = 0
): Promise<string[]> {
const results: string[] = []
// Get all files from the folder
let items = await FsExtra.readdir(folder).catch(error => {
if (errors) {
errors.push(error) // Save errors if we wish (e.g. folder perms issues)
}
return results
})
// Go through to the required depth and no further
folderDepth = folderDepth - 1
// Loop through the results, possibly recurse
for (const item of items) {
try {
const fullPath = Path.join(folder, item)
if (
FsExtra.statSync(fullPath).isDirectory() &&
folderDepth > -1)
) {
// Its a folder, recursively get the child folders' files
results.push(
...(await FileHelper.findFiles(fullPath, filePattern, errors, folderDepth))
)
} else {
// Filter by the file name pattern, if there is one
if (filePattern === '.*' || item.search(new RegExp(filePattern, 'i')) > -1) {
results.push(fullPath)
}
}
} catch (error) {
if (errors) {
errors.push(error) // Save errors if we wish
}
}
}
return results
}
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);
}
提醒一下:如果您计划对目录中的每个文件执行操作,请尝试vinylfs(流式构建系统gulp使用)。
