What should I do if IE cannot recognize react?

Solutions for incompatible solutions when the react project is opened in IE11

Scenario 1:

1. Install react-app-polyfill

npm i react-app-polyfill  --save

2. Introduce it in src/main.js (need to be placed in the first line)

import 'react-app-polyfill/ie11'  
import 'react-app-polyfill/stable'

Scenario 2:

Solution: Configure parameters in babel.config.js

module.exports = {
  // https://www.babeljs.cn/docs/babel-preset-env
  presets: [
    // bable预设, 兼容于ie11的语法配置
    [
      '@babel/preset-env',
      // 支持的最低环境版本
      {
        targets: {
          ie: '11',
          chrome: '58',
        },
        // 只包含你所需要的 polyfill,  即按需加载
        useBuiltIns: 'usage',
        corejs: 3,
      },
    ],
    // 转换vue语法
    '@vue/cli-plugin-babel/preset',
    // 转换react语法
    '@babel/preset-react',
  ],
  plugins: [...]
}

Scenario 3:

Solution: Configure transpileDependencies in vue.config.js

ps: First understand the parameters of transpileDependencies

Because, react uses There are syntax errors in the plug-in, so just put the package name that needs to be translated

// vue.config.js
 
module.exports = {
  ...
  transpileDependencies: [
    'moment',
    'crypto-js',
    '@ecc',
    //  就是这两个
    'react-sortablejs',
    'react-contenteditable',
  ],
};
