如何在 React Router v6 中重定向？

Question

I am trying to upgrade to React Router v6 ( react-router-dom 6.0.1 ).

Here is my updated code:

import { BrowserRouter, Navigate, Route, Routes } from 'react-router-dom';

<BrowserRouter>
  <Routes>
    <Route path="/" element={<Home />} />
    <Route path="/lab" element={<Lab />} />
    <Route render={() => <Navigate to="/" />} />
  </Routes>
</BrowserRouter>

The last Route is redirecting the rest of paths to / .

However, I got an error

TS2322: Type '{ render: () => Element; }' is not assignable to type 'IntrinsicAttributes & (PathRouteProps | LayoutRouteProps | IndexRouteProps)'. Property 'render' does not exist on type 'IntrinsicAttributes & (PathRouteProps | LayoutRouteProps | IndexRouteProps)'.

However, based on the documentation , it does have render for Route . How can I use it correctly?

Answer 1

I think you should use the no match route approach.

Check this in the documentation.

https://reactrouter.com/docs/en/v6/getting-started/tutorial#adding-a-no-match-route

import { BrowserRouter, Navigate, Route, Routes } from 'react-router-dom';

<BrowserRouter>
  <Routes>
    <Route path="/" element={<Home />} />
    <Route path="/lab" element={<Lab />} />
    <Route
        path="*"
        element={<Navigate to="/" replace />}
    />
  </Routes>
</BrowserRouter>

To keep the history clean, you should set replace prop. This will avoid extra redirects after the user click back. Thanks @Paul for this tip.

I found another way to do this:

import { useNavigate } from "react-router-dom";
let navigate = useNavigate();

useEffect(() => {
   if (LoggedIn){
      return navigate("/");
   }
},[LoggedIn]);

Create the file RequireAuth.tsx

import { useLocation, Navigate } from "react-router-dom";
import { useAuth } from "../hooks/Auth";

export function RequireAuth({ children }: { children: JSX.Element }) {
  let { user } = useAuth();
  let location = useLocation();

  if (!user) {
    return <Navigate to="/" state={{ from: location }} replace />;
  } else {
    return children;
  }
}

Import the component to need user a private router:

import { Routes as Switch, Route } from "react-router-dom";

import { RequireAuth } from "./RequireAuth";
import { SignIn } from "../pages/SignIn";
import { Dashboard } from "../pages/Dashboard";

export function Routes() {
  return (
    <Switch>
      <Route path="/" element={<SignIn />} />
      <Route
        path="/dashboard"
        element={
          <RequireAuth>
            <Dashboard />
          </RequireAuth>
        }
      />
    </Switch>
  );
}

      <BrowserRouter>
        <Routes>
          <Route path="home" element={<Home />} />
          <Route path="about" element={<About />} />
          <Route index element={<Navigate to="/home" replace />} />
        </Routes>
      </BrowserRouter>

FOR react-router VERSION 6

New example after editing-----> (more simple easy to read)

import {BrowserRouter as Router,Routes,Route} from 'react-router-dom';
import Home from '../NavbarCompo/About';
import Contact from '../NavbarCompo/Contact';
import About from '../NavbarCompo/About';
import Login  from '../NavbarCompo/Login';
import Navbar from '../Navbar/Navbar';
import Error from '../pages/error';
import Products  from '../pages/products';
import Data from '../NavbarCompo/Data';

const Roter=()=>{
    return (
    <Router>

            <Navbar />
        <Routes>
            
            <Route path='/' element={<Home />} />
            <Route path='/about' element={<About />} />
            <Route path='/contact' element={<Contact />} />
            <Route path='/login' element={<Login />} />
            <Route path='/product/:id' element={<Products />} />
            <Route path='/data' element={<Data />} />
            <Route path ='*' element={<Error />} />
        </Routes>


    </Router>
    )
}
export default Roter;

Look at the example

import React from "react";
import Form from "./compo/form";
import ReactDOM from "react-dom/client";
import { createBrowserRouter, RouterProvider, Route,Routes,Navigate } from "react-router-dom";

const router = createBrowserRouter([
  {
    path: "/",
    element: <Form />
  },
  {
    path: "/about",
    element: <h1>hola amigo,you are in about section</h1>
  },
  {
    path:"*",
    element:<Navigate to="/" replace />
  }
]);

const root = ReactDOM.createRoot(document.getElementById("root"));

root.render(
  <React.StrictMode>
    <RouterProvider router={router}></RouterProvider>
  </React.StrictMode>
);

Answer 6

import { useState } from "react"
import { Navigate } from "react-router-dom"
const [login, setLogin] = useState(true)
return (<>
{!login && <Navigate to="/login" />}
<>)

Answer 7

In V5 of react ie. react-router-dom we had Redirect component. But in V6 of react it is updated to Navigate components.

We can pass replace in this components to avoid unnecessary redirects on clicking back and forward option.

Demonstration for usage is attached below :

<Route  path="/" element={user ? <Home /> : <Register />} />
<Route path="/login" element={user ? <Navigate to="/" replace /> :  <Login />}  />
<Route path = "/register" element={user ? <Navigate to="/" replace /> :  <Register />} />

Answer 8

for class components, at the first you should make a functional component then use HOC technical to use useNavigate react hook. like this:

withrouter.js:

import {useNavigate} from 'react-router-dom';

export const withRouter = WrappedComponent => props => {
    return (<WrappedComponent {...props} navigate={useNavigate()}/>);
};

then use use it in other class components like this:

export default withRouter(Signin);

and use props for redirect like this:

this.props.navigate('/');

Answer 9

This is an example using useHistory from react-router-dom

import {useHistory} from 'react-router-dom';

const { REACT_APP_REST } = process.env;

function AllProducts() {

    const history = useHistory();

    const route = () => {
        history.push("/admin/product");
    }

    return (
        <>
            <Button
                className="btn-fill btn-wd"
        
                onClick={() => {
                    route()
                }}
            >
                NEW PRODUCT
            </Button>


        </>
    );
}

export default AllProducts;

Answer 10

import { useNavigate } from "react-router-dom"; import { Button } from "@mui/material";

const component =()=>{

const navigate = useNavigate();

const handelGoToLogin = () => {
    navigate('/auth/login')
}

return(<> //.........

Back

</>)
