I'am using react-router-dom v6 and mobex in my project and get an error when I use it as below.

main.tsx:

import React from 'react'
import ReactDOM from 'react-dom/client'
import App from './app/layout/App'
import './app/layout/styles.css'
import 'semantic-ui-css/semantic.min.css'
import 'react-toastify/dist/ReactToastify.min.css'
import 'react-calendar/dist/Calendar.css'
import 'react-datepicker/dist/react-datepicker.css'
import { store, StoreContext } from './app/stores/store'
import { BrowserRouter } from 'react-router-dom'
import { useNavigate } from 'react-router-dom';
export const navigate = useNavigate();

ReactDOM.createRoot(document.getElementById('root')!).render(
  <React.StrictMode>
    <StoreContext.Provider value={store}>
      <BrowserRouter>
        <App />
      </BrowserRouter>
    </StoreContext.Provider>
  </React.StrictMode>
)

userStore.ts:

import { UserFormValues } from './../models/user';
import { makeAutoObservable, runInAction } from "mobx";
import { User } from "../models/user";
import agent from '../api/agent';
import { store } from './store';
import { navigate } from '../../main';

export default class UserStore {
    user:User | null = null;

    constructor() {
        makeAutoObservable(this);
    }

    logout = () => {
        store.commonStore.setToken(null);
        window.localStorage.removeItem('jwt');
        this.user = null;
        navigate('/');
    }
}

Error:

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

In the old version it was working when I did it like this below:

main.tsx:

...
...
import { createBrowserHistory } from "history";
export const history = createBrowserHistory();
...
...

and userStore.tsx:

import { makeAutoObservable, runInAction } from "mobx";
import agent from "../api/agent";
import { User, UserFormValues } from "../models/user";
import { store } from "./store";
import { history } from "../../index";

export default class UserStore {
  user: User | null = null;

  constructor() {
    makeAutoObservable(this);
  }

  logout = () => {
    store.commonStore.setToken(null);
    window.localStorage.removeItem("jwt");
    this.user = null;
    history.push("/");
  };

How can i solve this problem?

CodePudding user response：

You cannot use hooks in class component. for route trough class component there is another way to do that. but I think in router 6 class component support is dropped. so you can change your class component to function component it is easy way.

CodePudding user response：

This line const navigate = useNavigate() can only be inside a React component or custom hook, as useNavigate is a hook. Seee Rules of Hooks to know more. One way to solve this is to change your logout function so it takes navigate as parameter, like so:

logout = (navigate) => {
  store.commonStore.setToken(null);
  window.localStorage.removeItem("jwt");
  this.user = null;
  navigate("/");
};

And call useNavigate in the component where you call logout and give navigate to it as paramater. Like so as an example:

import UserStore from "path/";
import { useNavigate } from "react-router-dom";

export default function Component() {
  const navigate = useNavigate();
  const userStore = UserStore();
  userStore.logout(navigate);

  return <div></div>;
}
