Push notifications with React and Firebase

Firebase, acquired by Google in 2014, has evolved into a comprehensive backend-as-a-service platform for mobile apps, offering tools like centralized authentication, real-time databases, and cloud functions. A key component of Firebase is Firebase Cloud Messaging (FCM), used for managing app notifications. The text details the process of enabling push notifications in a frontend React application using Firebase. It guides through setting up a sample React app, configuring Firebase, linking projects, and integrating cloud messaging. The article explains how to request notification permissions, register a client, and configure message listeners for both background and foreground notifications. Testing the setup involves sending test messages through the Firebase Cloud Messaging panel. The guide concludes by suggesting an alternate method for more granular control over notifications using a backend server and the firebase-admin library.
