<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. 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'
