Question

当尝试使用react-redux打字稿的新useSelector钩子（请参见下面的示例）时，该函数不存在错误：

Module '"../../../node_modules/@types/react-redux"' has no exported member 'useSelector'.  TS2305

示例：

import * as React from "react"
import { useSelector } from "react-redux"
import { Message } from "./Message"

export const MessageContainer = () => {
  const searchValue = useSelector((state) => state.search)
  return (
    <Message searchValue={searchValue} />
  )
}

使用的版本： “ react-redux”：“ ^ 7.1.0-alpha.5” “ @ types / react-redux”：“ ^ 7.0.9”

Answer 1

以下代码摘自redux doc本身有关打字稿的内容
typescript redux offical

interface RootState {
      isOn: boolean
    }

// TS infers type: (state: RootState) => boolean
const selectIsOn = (state: RootState) => state.isOn

// TS infers `isOn` is boolean
const isOn = useSelector(selectIsOn)

如前所述，在添加钩子之前说过，但是如果使用钩子，则最好这样编写Selector

将react-redux useSelector与打字稿一起使用
