记一次工做中的项目效率优化

事情的开始是这样子的...
产品: 咱们要作一个公众号推广活动，跟渠道方合做的，巴拉巴拉...
我: 好的...
项目上线后没几天，产品又找上我说，咱们要新增一个渠道合做方
我一听，心中大为警戒，以我多年的经验来判断，问了一句，除了这个后面还会不会有别的合做方
产品: 不必定，可能还会有，￥%……

so... 仍是要作好那种能够配置的，稍微自动的。

访问一个地址，怎么去区分不一样渠道商呢？

只有一个办法就是url里面添加 channel 字段区分，去匹配相应的渠道内容。

而后，如今要作的是就把以前，全部的可能会变更的内容，都提取出来... 统一文件格式，名称等...

之后就单独改这一个文件就行了。

初步看来仍是不错的，可是低估了公司的影响力，渠道商愈来愈多，修改文件，也变得枯燥无味，也占用时间，还会担忧影响到其它页面的内容，都要自测一遍。代码预览以下

能够看到引入文件里面占用了大部分重复的东西，引入图片不一样的地方就是渠道文件夹名称。

一个个新增渠道也是很以为很麻烦的事情，复制粘贴修改，再滚动复制粘贴修改...

这种低级效率的事情，实在不想写，怎么办...

不慌，有webpack这么强大的工具固然要好好利用，经过 require.context去处理引入文件问题。而后经过keys()遍历文件夹下的文件。

具体功能，能够访问require.context了解，就很少说啦

这时候代码优化以下：

const modulesFiles = require.context('@/assets/image/fission', true, /\guide.(png|jpg)$/) 
const modulesFilesKeys = modulesFiles.keys().map(file => {
  return file.replace(/(^.\/)(\w+)(\/guide.(png|jpg))/, '$2')
})
// console.log(modulesFilesKeys)
const guideImages = {}
const giveImages = {}
const topPic = {}
const gzhImages = {}
const dxlj = {}
const channelLogo = {}
const posterTitle = {}
const channelEwm = {}
modulesFilesKeys.forEach(name => {
  guideImages[name]   = require(`@/assets/image/fission/${name}/guide.png`)
  giveImages[name]    = require(`@/assets/image/fission/${name}/give.png`)
  topPic[name]        = require(`@/assets/image/fission/${name}/toppic.png`)
  gzhImages[name]     = require(`@/assets/image/fission/${name}/gzh.png`)
  dxlj[name]          = require(`@/assets/image/fission/${name}/dxlj.png`)
  channelLogo[name]   = require(`@/assets/image/fission/${name}/logo.png`)
  posterTitle[name]   = require(`@/assets/image/fission/${name}/posterTitle.png`)
  channelEwm[name]    = require(`@/assets/image/fission/${name}/ewm.jpg`)
})
export default {
  data () {
    return {
      channel: '',
      channelName: {
        xeskids: '学而思kids',
        jiazhangbang: '家长帮',
        hangzhouxes: '杭州学而思',
        hefeixes: '合肥学而思',
        huizhouxes: '惠州学而思',
        shenzhenxhxt: '深圳小猴学堂',
        zhongshanxes: '中山学而思',
        zhongshanysx: '中山幼升小',
        jiazhangbangbc: '家长帮编程',
        nanningxes: '南宁学而思',
        shaoxingxes: '绍兴学而思',
        shenzhenxes: '深圳学而思',
        tianjinxes: '天津学而思',
        nanjingxes: '南京学而思',
        xiamenjzb: '厦门家长帮',
      },
      guideText: {
        xeskids: '学而思kids',
        jiazhangbang: 'codemonkey',
        hangzhouxes: 'codemonkey',
        hefeixes: 'codemonkey',
        huizhouxes: 'codemonkey',
        shenzhenxhxt: 'codemonkey',
        zhongshanxes: 'codemonkey',
        zhongshanysx: 'codemonkey',
        jiazhangbangbc: 'codemonkey',
        nanningxes: 'codemonkey',
        shaoxingxes: 'codemonkey',
        shenzhenxes: 'codemonkey',
        tianjinxes: 'codemonkey',
        nanjingxes: 'codemonkey',
        xiamenjzb: 'codemonkey',
      },
      guideImages,
      giveImages,
      topPic,
      channelEwm,
      gzhImages,
      dxlj,
      channelLogo,
      posterTitle,
    }
  },
  created() {
    this.channel = sessionStorage.getItem('channel')
  },
}

可是，如今并无达到个人目的。 渠道商名字 channelName, 用来复制公众号回复的guideText，仍须要手动修改。

有没有办法不手动修改这些数据呢？

问题一直都有的，解决问题的办法也老是会有的...(引用某我的常常说的话😂)

引入文件，能够正则匹配文件名，不就能够获取到了嘛。。。

新建一个txt文件，把渠道名称做为文件名。

最终优化代码以下：

const channelName = {}
const modulesFiles = require.context('@/assets/image/fission', true, /\/[\s\S]+\.txt$/) // 匹配对应渠道.txt文件
const modulesFilesKeys = modulesFiles.keys().map(file => {
  let regResult = file.replace(/^.\/(\w+)\/([\s\S]+).txt/, '$1,$2')
  let fileName = regResult.split(',')[0] // 匹配对应渠道文件夹名字
  let txtName = regResult.split(',')[1] // 匹配对应渠道.txt文件名
  channelName[fileName] = txtName
  return fileName
})
// console.log(modulesFilesKeys)
const guideText = {}
const guideImages = {}
const giveImages = {}
const topPic = {}
const gzhImages = {}
const dxlj = {}
const channelLogo = {}
const posterTitle = {}
const channelEwm = {}
modulesFilesKeys.forEach(name => { // 根据渠道文件夹名字访问该渠道下的资源
  guideText[name]     = name === 'xeskids' ? '学而思kids' : 'codemonkey'
  guideImages[name]   = require(`@/assets/image/fission/${name}/guide.png`)
  giveImages[name]    = require(`@/assets/image/fission/${name}/give.png`)
  topPic[name]        = require(`@/assets/image/fission/${name}/toppic.png`)
  gzhImages[name]     = require(`@/assets/image/fission/${name}/gzh.png`)
  dxlj[name]          = require(`@/assets/image/fission/${name}/dxlj.png`)
  channelLogo[name]   = require(`@/assets/image/fission/${name}/logo.png`)
  posterTitle[name]   = require(`@/assets/image/fission/${name}/posterTitle.png`)
  channelEwm[name]    = require(`@/assets/image/fission/${name}/ewm.jpg`)
})
export default {
  data () {
    return {
      channel: '',
      channelName,
      guideText,
      guideImages,
      giveImages,
      topPic,
      channelEwm,
      gzhImages,
      dxlj,
      channelLogo,
      posterTitle,
    }
  },
  created() {
    this.channel = sessionStorage.getItem('channel')
  },
}

之后再新增渠道，只须要渠道新建文件夹，以及该渠道下的各个资源，上去文件就能够啦，不再用担忧修改代码的问题了。✌️✌️✌️
