umi-plugin-keep-alive

中文说明 | English

此 <KeepAlive> 功能基于 react-activation

在线示例

umi 多 tabs 示例：https://codesandbox.io/s/umi-keep-alive-tabs-demo-knfxy

使用方法

1. 安装

   npm install umi-plugin-keep-alive --save
   # or
   yarn add umi-plugin-keep-alive

2. 从 umi 中导出 KeepAlive，包裹在需要被缓存的组件上

   import { useState } from 'react'
   import { KeepAlive } from 'umi'
   
   function Counter() {
     const [count, setCount] = useState(0)
   
     return (
       <div>
         <p>count: {count}</p>
         <button onClick={() => setCount(count => count + 1)}>add</button>
       </div>
     )
   }
   
   export default function() {
     const [show, setShow] = useState(true)
   
     return (
       <div>
         <h1>Page index</h1>
         {show && (
           <KeepAlive>
             <Counter />
           </KeepAlive>
         )}
         <button onClick={() => setShow(show => !show)}>toggle</button>
       </div>
     )
   }

文档

所有来自 react-activation 都可以由 umi 导出

import {
  KeepAlive,
  useActivate, 
  useUnactivate, 
  withActivation,
  withAliveScope, 
  useAliveController
} from 'umi'
