How to implement Keycloak authentication in React

The tutorial provides a comprehensive guide to securing a React app with Keycloak, an open-source identity and access management tool. It begins with setting up a Keycloak server using Docker and creating a realm and users within the Keycloak admin console. The guide then details how to integrate Keycloak with a React frontend app, using Tailwind CSS for styling and React Router DOM for navigation. It explains the creation of protected routes accessible only by authenticated users, using Keycloak's JavaScript adapter to manage authentication states. The tutorial also includes steps for adding login/logout functionality to the app's navigation bar, ensuring the secured page remains inaccessible to unauthenticated users.
