nodejs對項目下全部空文件夾建立gitkeep

項目/框架初始化時可能須要保留一些空文件，這時候就須要批量新增gitkeep

const fs = require('fs')
const baseurl = 'D:/test'
const ignoreDir = ['.git', '.vscode', 'node_modules']
addGitkeep(baseurl)
function addGitkeep(url) {
    fs.readdir(url, {withFileTypes: true}, (err, files) => {
        err && console.log(err)
        //該目錄下沒有文件
        if (!files.length) {
            return fs.writeFile(url + '/.gitkeep', null, err => {
                err && console.log(err)
            })
        }
        files.forEach(dirent => {
            if (!ignoreDir.includes(dirent.name) && dirent.isDirectory()) {
                addGitkeep(url + '/' + dirent.name)
            }
        })
    })
}
