# reactĬonst authUserContext = React.createContext() Once we have created a new file, now we will create a context and assign it to a constant authUserContext. We will create a new file, AuthUser.js, in the’ src’ folder. Now, let’s run our app to check if all dependencies are installed correctly. # reactĪfter creating our new application in React, we will go to our application directory using this command. Let’s create a new application by using the following command. We will use a fake AuthUser Hook to check the authentication status. First, we need to add functionality to authenticate the user to start working on protected routes. React router does not provide any functionality for this, but it is very easy and straightforward to add this functionality. But protected routes such as dashboard and profile settings can only be accessed by logged-in users. React router provides us with protected routes they let us choose which routes users can visit based on their user roles or whether they are logged in or not.įor example, we have a home, about, contact, and login page that all users can access. When building a commercial web app or a website in React, we often need to hide certain routes in our application from users who are not logged in or do not have a certain user role required to access those routes. We will introduce protected routes and authentication with react-router in React application.
