#REACT ROUTER DOM NAVLINK GENERATOR#
For example, the gatsby static site generator requires you to use its implementation of Link. In some cases you may need to provide a custom Link implementation.
The best place to add these implementation details would be the ProtectedRoute component. The exported components are wrapped versions of the Link and NavLink exports of react-router-dom. In order to implement such smart redirect, we have to "remember" the location from where the redirect happened to the Login page. After the login, you will get a redirect to the desired protected route. In other words: If you open an application at a protected route, but you are not logged in, you get a redirect to the Login page. In modern applications, you will get a redirect to your previously visited page after a log in. Dashboard page) need to be secured from the server-side too. Therefore, all sensitive API calls that happen on protected pages (e.g. removing the condition to redirect from the ProtectedRoute).
#REACT ROUTER DOM NAVLINK CODE#
Next React Router comes finally into play, because after a successful authentication usually a user gets redirected from the login page (here: Home page) to a landing page (here: Dashboard page) whereas the latter is only accessible for authenticated users:Ĭontinue Reading: React Router 6 Private Routesīe aware: Anyway, even though the route is protected and not accessible by unauthorized users anymore, a malicious user could still modify the client-side code in the browser (e.g. We have all business logic for the essential authentication in place and are able to consume this business logic (state + event handlers) anywhere in the React application with the help of React's context (here: the custom useAuth hook). React Router Redirect after Authentication Then we passed the state and the event handlers as context to all components which are interested in the authentication state and/or sign in/out users. login, logout) in the new custom Provider component instead of cluttering the App component with these implementation details. In addition, we defined all the necessary handlers (e.g. We have created a custom Provider component which keeps track of the token state (read: authentication state). That's it for using a more elaborate context approach for authentication in React.
