We can consume the Redirect component from react-router-dom, in order to redirect a user from the / path to the /login:

<Route
    path="/"
    render={() =><Redirectto="/login"/>}
    exact
/>

We can use this component to Redirect a user from one page to another, based on certain conditions. One of the situations is, if a user is logged in, we can Redirect the user to the dashboard page; otherwise, we can ask the user to log in:

import React from "react";
import { Route, Redirect } from "react-router-dom";
const redirect = () => (
 <Route
   exact
   path="/"
   render={() =>
     loggedIn ? <Redirect to="/dashboard" /> : <PublicHomePage />
   }
 />
);
export default redirect;

You may be wondering how we can test our Redirect component. Our test could look as follows:

import React from "react";
import renderer from "react-test-renderer";
import RedirectDemo from "../redirect";
jest.mock("react-router-dom", () => ({ Redirect: "Redirect", Route: "Route" }));
it("should render correctly", () => {
const component = renderer.create(<RedirectDemo />);
expect(component.toJSON()).toMatchSnapshot();
});
