react全家桶實現招聘app-專案準備（一）

而今才到當時錯發表於2018-08-22
ReactAPP

1.1 專案技術

a. 使用react全家桶 + es6 + webpack + antd-mobile

b. 採用模組化、元件化、工程化

c. Node + express + mongodb + socketIO

1.2 開始專案

專案原始碼設計

react全家桶實現招聘app-專案準備（一）

1.2.1 移動端在處理點選事件的時候，會有300毫秒的延遲。恰恰是這300毫秒的延遲，會讓人有一種卡頓的體驗。所以在index.html中引入外掛fastclick
<script>
  if ('addEventListener' in document) {
    document.addEventListener('DOMContentLoaded', function() {
      FastClick.attach(document.body);
    }, false);
  }
  if(!window.Promise) {
    document.writeln('<script src="https://as.alipayobjects.com/g/component/es6-promise/3.2.2/es6-promise.min.js"'+'>'+'<'+'/'+'script>');
  }

2 元件打包

2.1 安裝依賴

npm install --save-dev babel-plugin-import react-app-rewired
複製程式碼

2.2 在更目錄下建立 config-overrides.js

const {injectBabelPlugin} = require('react-app-rewired');

module.exports = function override(config, env) {

config = injectBabelPlugin(['import', {libraryName: 'antd-mobile', style: 'css'}],

config);

return config;

}
複製程式碼

修改配置: package.json

"scripts": {

"start": "react-app-rewired start",

"build": "react-app-rewired build",

"test": "react-app-rewired test --env=jsdom",

"eject": "react-scripts eject"

}
複製程式碼

在index.js中寫入

import React from 'react'

import ReactDOM from 'react-dom'

import {Button} from 'antd-mobile'

ReactDOM.render(

<Buttontype='primary'>招聘</Button>,

document.getElementById('root')

)

2.3 將主體的背景顏色從 blue 變為 green

新增less-loader要加上版本@2.7.3，否則會載入最新版本， 電腦無法執行

npm install --save-dev less@2.7.3 less-loader

配置: config-overrides.js

const {injectBabelPlugin, getLoader} = require('react-app-rewired');

  return rule.loader && rule.loader.indexOf(`file-loader`) != -1;

  config = injectBabelPlugin(['import', {
    libraryName: 'antd-mobile',
    //style: 'css',
