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) => {
        return ('00' + str).substr(str.length)
    }
    let doFormatDate = (date, fmt) => {
        if (/(y+)/.test(fmt)) {
            fmt = fmt.replace(RegExp.$1, (date.getFullYear() + '').substr(4 - RegExp.$1.length))
        }
        let obj = {
            'M+': date.getMonth() + 1,
            'd+': date.getDate(),
            'h+': date.getHours(),
            'm+': date.getMinutes(),
            's+': date.getSeconds()
        }
        for (let k in obj) {
            if (new RegExp(`(${k})`).test(fmt)) {
                let str = obj[k] + ''
                fmt = fmt.replace(RegExp.$1, RegExp.$1.length === 1 ? str : padLeftZero(str))
            }
        }
        return fmt
    }

    return doFormatDate(date, fmt)
}

// 遍历 a 标签
$('a').each(function (i, el) {
    let node = $(el)
    let nodeText = node.text()
    let nodeHref = node.attr('href')
    let nodeCreateTime = formatDate(node.attr('add_date'))
    let nodeUpdateTime = formatDate(node.attr('last_modified'))
    // 查找父目录
    let parentDT = node.parents('dt')
    let parentDirPathArr = []
    let parentDirPathStr = ''
    parentDT.each(function (j, parent) {
        let firstChild = $(parent).children().first()
        if (firstChild.is('h3')) {
            let dirName = firstChild.text()
            if (firstChild.attr('personal_toolbar_folder')) {
                dirName = timeNow
            }
            parentDirPathArr.push(dirName)
        }
    })
    parentDirPathStr = parentDirPathArr.reverse().join(separator)
    // console.log(parentDirPathStr)
    // 初始化当前目录路径
    if (!dirNameObj[parentDirPathStr]) {
        dirNameObj[parentDirPathStr] = []
    }
    dirNameObj[parentDirPathStr].push({
        text: nodeText,
        href: nodeHref,
        create_time: nodeCreateTime,
        update_time: nodeUpdateTime
    })
})

setTimeout(function () {

    Object.keys(dirNameObj).map(function (key) {
