React 学习——zustand异步操作

跟写普通方法一样，只不过再最后赋值的时候用set就行了。

import { useEffect } from 'react'
import { create } from 'zustand'

// 创建store
const useStore = create(set=>{
  return {
    channelList: [],
    fetchChannelList: async()=>{
      const res = await fetch('http://geek.itheima.net/v1_0/channels')
      const jsonData = await res.json()
      set(state => ({ channelList: jsonData.data.channels }))
    }
  }
}) 
const App = () => {
  const { channelList,fetchChannelList } = useStore();
  useEffect(()=>{
    fetchChannelList()
  },[])
  return (
    <div className="home">
      <ul>
        {channelList.map(item=>(<li key={item.id}>{item.name}</li>))}
      </ul>
    </div>
  )
}
export default App
