自己写的几个node文件系统小方法

1. 遍历入参中对应文件夹下的所有文件，并返回对应文件完整路径

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

function travel(basePath, callback) {
  fs
    .readdirSync(basePath)
    .forEach((file) => {
      let filePath = path.join(basePath, file)
      if (fs.statSync(filePath).isDirectory()) {
        // 如果是文件夹则递归继续
        travel(filePath, callback)
      } else {
        callback(filePath)
      }
    })
}

// 使用
let basePath = './server' // 可以是以盘名开头的绝对路径：'F:/server'

travel(basePath, function (filePath) {
  console.log(filePath)
})

2. 根据入参路径创建对应目录和文件

const fs = require("fs")
const path = require("path")
// 生成可识别的完整路径
const toResolvePath = (...file) => path.resolve(process.cwd(), ...file);
// 创建目录
const dirCreate = (targetPath, cb) => {
    if (fs.existsSync(targetPath)) {
        cb()
    } else {
        dirCreate(path.dirname(targetPath), () => {
            fs.mkdirSync(targetPath)
            cb()
        })
    }
}
const generateDirectoryCreate = async (dirPath) => {
    return new Promise((resolve, reject) => {
        dirCreate(dirPath, resolve)
    })
}

// 创建文件
const generateFileCreate = async (filePath, content) => {
    return new Promise((resolve, reject) => {
        fs.writeFile(filePath, content, 'utf8', err => {
            if (err) {
                console.log(err.message);
                reject(err)
            } else {
                resolve()
            }
        })
    })
}

// 使用
const basePath = './aaa/bbb'
const resolvedPath = toResolvePath(basePath);
// 根据path创建目录
generateDirectoryCreate(resolvedPath);
// 根据path创建文件
generateFileCreate(toResolvePath(basePath, 'index.js'), 'aaabbb\ncccddd');
