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
非递归版本
您并没有说要递归地执行,所以我假设您只需要目录的直接子级。
示例代码:
const fs = require('fs');
const path = require('path');
fs.readdirSync('your-directory-path')
.filter((file) => fs.lstatSync(path.join(folder, file)).isFile());
其他回答
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)。
如果有人还在搜索这个,我会这样做:
从“fs”导入fs;从“path”导入路径;const getAllFiles=目录=>fs.readdirSync(dir).reduce((files,file)=>{常量名称=路径.连接(目录,文件);const isDirectory=fs.statSync(名称).isDirectory();return isDirectory?[…file,…getAllFiles(名称)]:[…files,名称];}, []);
它的工作对我很好
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) {
// ...
}
};

listFileNames("resources/countries") #=> ["usa", "japan", "gb"]
我最近为此开发了一个工具,它可以做到这一点。。。它异步获取目录并返回项目列表。您可以获取目录、文件或两者,首先是文件夹。如果不想获取整个文件夹,也可以对数据进行分页。

这是链接,希望它能帮助到某人!
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
}
