项目环境搭建

  使用create-react-app

CSS使用styled-components

  yarn add styled-components

引入reset.css样式

  import { createGlobalStyle } from 'styled-components'

  export const GlobalStyle = createGlobalStyle ` `
  然后在App.js中引入GlibalStyle组件
引入iconfont
  配置跟reset.css一样
引入react-transition-group
   实现组件动画效果
引入redux  react-redux
  如何配置 首先创建store 文件夹   index.js   reducer.js只一个纯函数
  然后App.js引入Provider  store
  接着在组件中使用connect做连接    connect(mapStateToProps, mapDispathcToProps)(Header)
使用redux-devtool-extension插件
  https://github.com/zalmoxisus/redux-devtools-extension
  如何使用 
  import { createStore, applyMiddleware, compose } from 'redux';

+ const composeEnhancers = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;
+ const store = createStore(reducer, /* preloadedState, */ composeEnhancers(
- const store = createStore(reducer, /* preloadedState, */ compose(
    applyMiddleware(...middleware)
  ));

使用combineReducer对reducer拆分

  修改store下的reducer.js代码

import { combineReducers } from 'redux'
import { reducer as headerReducer} from '../components/header/store'

export default combineReducers({
  header: headerReducer
})

使用actionCreators.js和actionTypes.js对store代码优化

使用immutable.js和redux-immutable

  yarn add redux-immutable

  生成的immutable对象,改对象不可改变

  yarn add immutable

  如何使用

import {fromJS} from 'immutable'

const defaultState = fromJS({
  focused: false
})
const mapStateToProps = state => {
  return {
    focused:state.header.get('focused')
  }
}
export default (state = defaultState, action) => {
  if (action.type === actionTypes.SEARCH_BLUR) {
    return state.set('focused', false)
  }
  if (action.type === actionTypes.SEARCH_FOCUS) {
    return state.set('focused', true)
  }
  return state
}

使用redux-thunk

  异步操作不在componentDidMount中操作

  放到action

  yarn add redux-thunk

后端使用koa koa-router  koa-cors mock

  模拟后端服务器

前端使用axios

  跨域配置  "proxy": "http://localhost:8080"

安装react-router-dom  

  import {BrowserRouter, Route} from 'react-router-dom'

  <BrowserRouter>
    <div>
      <Header/>
      <Route path="/" exact component={Home}/>
      <Route path="/detail/:id" exact component={Detail}/>
    </div>
  </BrowserRouter>

  获得pathname

    const {pathname} = this.props.location

  页面跳转

    this.props.history.push('/')

  页面重定向

    <Redirect from='/...' to='/...' />
