Umi实现路由动画
1、首先在src目录下建一个layouts文件夹
layouts目录下创建两个文件 index.tsx和index.less
index.tsx文件下代码:

import React, { useState, useEffect } from 'react'
import { TransitionGroup, CSSTransition } from 'react-transition-group'
import { history as Router, withRouter } from 'umi'
import { Switch } from 'react-router'
import './index.less'

const routerType = {
    'POP': 'back',
    'PUSH': 'in',
    'REPLACE': 'in'
}

export default withRouter(({ location, children, history }) => {
    return (
        <div>
            <TransitionGroup style={{ height: '100%' }} className='transition_wrapper' childFactory={(child) => (
                React.cloneElement(child, { classNames: routerType[history.action] })
            )}>
                <CSSTransition key={location.pathname} appear timeout={3000}>
                    <Switch location={location}>{(children as any)?.props?.children}</Switch>
                </CSSTransition>
            </TransitionGroup>
        </div>
    )
})

index.less文件下代码:

.in-enter-active {
    // 入场的过渡状态类
    transition: all 3s;
    transform: translate(0, 0) !important;
}

.in-enter-done {
    // 入场的动画的结束状态类
    // opacity: 0.5;
    transform: translate(0, 0) !important;
}

.in-enter {
    // 入场的动画开始状态类
    z-index: 5 !important;
    transform: translate(100%, 0);
}

.in-exit-active {
    // 离场动画
    opacity: 0;
    transition: all 3s;
    transform: translate(-100%, 0) !important;
}

.in-exit {
    // 离场动画开始
    // transform: translate(0, 0)!important;
}

.in-exit-done {
    // 离场动画结束

}

// 返回动画
.back-enter-active {
    // 入场的过渡状态类
    transition: all 3s;
    transform: translate(0, 0) !important;

}

 .back-enter-done {
     // 入场的动画的结束状态类
     opacity: 0.5;
     transform: translate(0, 0);
 }

.back-enter {
    // 入场的动画开始状态类
    z-index: 5 !important;
    transform: translate(-100%, 0);
}

.back-exit-active {
    // 离场动画
    opacity: 0;
    transition: all 3s;
    transform: translate(100%, 0) !important;
}

.back-exit {
    // 离场动画开始
    // transform: translate(0, 0)!important;
}

.back-exit-done {
    // 离场动画结束

}

2、在pages下创建两个文件夹

Par/index.tsx 代码

  <div onClick={() => { history.push('/sun') }} style={{ width: '100%', height: '100%', background: 'green' }}>
            <h1>第一个页面</h1>
  </div>

Sun/index.tsx 代码

  <div onClick={() => { history.push('/par') }} style={{ width: '100%', height: '100%', background: 'green' }}>
            <h1>第二个页面</h1>
  </div>

3、路由配置

 routes: [
    {
      path: '/', component: '@/layouts/index.tsx',
      routes: [
        { path: '/par', component: '@/pages/Par'},
        { path: '/sun', component: '@/pages/Sun'},
      ]
    }
  ],
