升级 react , react-dom

网上有一些的讲react15升级到react16升级的教程。但是很少从整体讲，都是从单个知识点讲。很多都是只讲react本身的升级，如：PropTyPEs 引用从react模块改成单独的PRop-types模块。但是一般项目的架构都是：react+react-router+redux+react-redux+react-router-redux。所以自己整理一下完整的升级过程。

react15升级到react16涉及以下几个方面：

• react-hot-loader
• proptypes
• react-redux
• react-router

react-hot-loader 升级

• react-hot-loader 升级最新
• webpack.base.conf.js

if (env === 'development') {
    @H_304_39@// _loaders.unshift('react-hot');
}

• .babelrc 增加react-hot-loader配置

"plugins": [
    "react-hot-loader/babel"
]

proptypes 调整

React-PropTypes-to-prop-types.js

1. Go to the /web directory on your project
2. npm install global add jscodeshift, this will add jscodeshift
3. gIT clone https://github.com/reactjs/re... this will add react-codemod
4. cd react-codemod && npm install cd ..
5. jscodeshift -t <codemod-script> <path> to transform your deprecated code. For example, if you want to fix prop-types errors in jsx files in the components directory, you can run something like: jscodeshift -t react-codemod/transforms/React-PropTypes-to-prop-types.js app/components/**/*

react-redux 升级

react-redux@5.0.6 版本以上

react-router 升级
