反应，得到错误：无效的钩子调用。 Hooks 只能在函数组件的主体内部调用

Question

Can anyone help me with React Hooks basics, I am relatively new and couldn't find proper help online

import React from 'react'
import { auth, provider } from "../../../firebaseSetup";
import { useNavigate } from "react-router-dom"


const GoogleAuth = async() => {
  const navigate = useNavigate()

    auth.signInWithPopup(provider).then(() => {
      navigate('/home');
    }).catch((error) => {
      console.log(error.message)
    })
}
export  default GoogleAuth

I get error on const navigate = useNavigate() saying:

Error: Invalid hook call. Hooks can only be called inside of the body of a function component

Answer 1

What they want for useNavigate (and all hooks) is to be called only at the top level of a React component or a custom hook.

Don't call Hooks inside loops, conditions, or nested functions. Instead, always use Hooks at the top level of your React function, before any early returns.

See Rules of Hooks for more.

A solution to your problem could be calling const navigate = useNavigate() in the component where you will use GoogleAuth , and pass navigate as parameter. As an example like so:

import React from 'react'
import { auth, provider } from "../../../firebaseSetup";
import { useNavigate } from "react-router-dom"


const GoogleAuth = async(navigate) => {
    auth.signInWithPopup(provider).then(() => {
      navigate('/home');
    }).catch((error) => {
      console.log(error.message)
    })
}
export  default GoogleAuth

import GoogleAuth from "GoogleAuth";
const App = ()=>{
       /* 
          here at the top level, not inside an if block,
          not inside a function defined here in the component...
       */
       const navigate = useNavigate(); 
       useEffect(()=>{
         GoogleAuth(navigate)
       },[])
       return <div></div>
    }
export default App;
