需求：
闲来无事，想把自己收藏的一些书签按目录来转成md文件。
于是乎就有了下面这个小工具：
bookmark2md
先上源码：
// 配置文件
config.js
/**
* Created by OXOYO on 2017/10/16.
*/
exports = module.exports = {
// 书签文件
bookmarksFile: './bookmarks.html',
// 生成目录
mdFilePath: './md/',
// 排除目录
unlessPath: ['OXO', 'OYO']
}// 核心文件
bookmark2md.js
/**
* Created by OXOYO on 2017/10/13.
*/
const fs = require('fs')
const cheerio = require('cheerio')
const config = require('./config')
// console.log('config', config)
const html = fs.readFileSync(config.bookmarksFile)
const $ = cheerio.load(html)
// 当前时间
const timeNow = (new Date()).getTime()
// 目录名称对象
const dirNameObj = {}
// 分割符
const separator = '=>'
// 写文件
const writeFile = function (fileName, content, filePath) {
filePath = filePath ? filePath : './md/'
// 写入文件
fs.writeFile(filePath + fileName, content, function (err) {
if (err) {
return console.error(err)
} else {
console.log(fileName + ' created success!')
}
})
}
// 日期格式化
const formatDate = (time, fmt = 'yyyy-MM-dd hh:mm') => {
// 10位时间戳格式化
let timeStr = time + ''
if (timeStr.length < 13) {
time = time * (Math.pow(10, 13 - timeStr.length))
}
time = parseInt(time)
if (isNaN(time)) {
return ''
}
let date = new Date(time)
let padLeftZero = (str) => {

}

}
let obj = {
'M+': date.getMonth() + 1,
'd+': date.getDate(),
'h+': date.getHours(),
'm+': date.getMinutes(),
's+': date.getSeconds()
}
for (let k in obj) {
