React 编写项目连环套路

搭建一个项目

公共部分放一块：index.js style.js store.js reducer.js actionCreateors.js actionTypes.js

分页        一块一块放 拆分在 compentns 里面存放 index.js style.js store.js reducer.js actionCreateors.js actionTypes.js

路由        exact 不会向后取值 不会影响到路由触发

分模块管理

/index

import React,{Component} from 'react';

import {
    HomeWapper,
        HomeLeft,
        HomeRight
} from './style';

import  List  from './components/List';
import  Topic  from './components/Topic';
import  Recommend  from './components/Recommend';
import  Writer  from './components/Writer';

class Home extends Component{
    render(){
        return(

            <HomeWapper>
                <HomeLeft>
                    <img className="banner-img" src="https://upload.jianshu.io/admin_banners/web_images/4592/22f5cfa984d47eaf3def6a48510cc87c157bf293.png?imageMogr2/auto-orient/strip|imageView2/1/w/1250/h/540"/>
                    <Topic/>
                    <List/>
                </HomeLeft>
                <HomeRight>
                    <Recommend/>
                    <Writer/>
                </HomeRight>
            </HomeWapper>
        )
    }
}

export default Home;

/style

import styled from 'styled-components';
import logo from '../../statics/logo.png';

  export const HeaderWrapper = styled.div`
    position:relative;
    width：100%;
    height:58px;
    border-bottom:1px solid #f0f0f0;
  `;

Store(只有一个，reducer有多个)

import {createStore , compose , applyMiddleware } from 'redux';
import reducer from './reducer';
import thunk from 'redux-thunk';

const composeEnhancers = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;
const store = createStore(reducer,composeEnhancers(

    applyMiddleware(thunk)

));

export default store;

Reducer（分块创建 ，最后合并为一个）

import { fromJS } from 'immutable';

const defaultState = fromJS({
    topic:[
    {
        id:1,
        title:'社会热点',
        imgUrl:'https://s.cn.bing.net/th?id=OJ.hCd0aXzY79mTlQ&w=75&h=75&pid=MSNJVFeeds',
    },
    {
        id:2,
        title:'新闻联播',
        imgUrl:'https://s.cn.bing.net/th?id=OJ.hCd0aXzY79mTlQ&w=75&h=75&pid=MSNJVFeeds',
    },
    {
        id:3,
        title:'项目咨询',
        imgUrl:'https://s.cn.bing.net/th?id=OJ.hCd0aXzY79mTlQ&w=75&h=75&pid=MSNJVFeeds',
    }
    ]
});

export default (state = defaultState,action)=>{
    switch (action.type){
        case:
            return;

        default:
            return state;

    }

} ;

actionCreateors（创建action状态的文件）

import * as actionTypes from './actionTypes';
import { fromJS } from 'immutable';
import axios from 'axios';

const changeList = (data) => ({
    type: actionTypes.CHANGELIST,
    data: fromJS(data),
    totalpage: Math.ceil(data.length / 10)
});

export const inputFocus = ()=>({
     type:actionTypes.INPUTFOCUS
});

export const inputBlur = () =>({
     type:actionTypes.INPUTBLUR
});

export const mouseEnter= () =>({
    type:actionTypes.MOUSEENTER
});

export const mouseLeave = () =>({
    type:actionTypes.MOUSELEAVE
});

export const changePage = (page) =>({
    type:actionTypes.CHANGEPAGE,
    page
})

// 异步请求数据 获取搜索框里面的数据
export const getList = () =>{
    return(dispath) =>{
        axios.get('/api/headerList.json').then((res)=>{
            const data = res.data;
            dispath(changeList(data.listData));

        }).catch(()=>{
            console.log('err:1','msg:not found  404');
        });
    }
};

actionTypes（action常量定义文件）

export const INPUTFOCUS = 'header/INPUTFOCUS';
export const INPUTBLUR = 'header/INPUTBLUR';
export const CHANGELIST = 'header/CHANGELIST';
export const MOUSEENTER = 'header/MOUSEENTER';
export const MOUSELEAVE = 'header/MOUSELEAVE';
export const CHANGEPAGE = 'header/CHANGEPAGE';

记得写”命名空间“

connect  连接props数据（

mapStateToProps，

mapDispatchToProps

）

数据 state

方法路径dispath

const mapStateToProps = (state)=>{
    return{

      focus:state.getIn(['header','focus']),
      list :state.getIn(['header','list']),
      page:state.getIn(['header','page']),
      show:state.getIn(['header','show']),
      totalpage:state.getIn(['header','totalpage'])
    }
}

const mapDispatchToProps = (dispatch)=>{
    return{

        handleMouseLeave(){
          dispatch(actionCreators.mouseLeave());
        },

        handleChangePage(page,totalpage,spin){

          let rotate = spin.style.transform.replace(/[^0-9]/ig,'');

          if(rotate){
            rotate = parseInt(rotate,10);
          }else{
            rotate = 0;
          }

          spin.style.transform = 'rotate(' + (rotate + 1000) + 'deg)';

          if(page < totalpage){
              dispatch(actionCreators.changePage(page + 1));
          }else{
            dispatch(actionCreators.changePage(1));
          }

        }

    }
}

export default connect(mapStateToProps,mapDispatchToProps)(Header);
