Approach to create a Real-time Notification
- It receives real-time updates via a WebSocket connection using the socket.io-client library.
- app/page.js is a page component that uses the socket.io-client library to connect to the server and listen for notifications. When a notification is received, it is displayed on the page.
- app/layout.js is a wrapper for all pages in the app. It’s a good place to put shared components and styles.
- app/add/page.js is the page component for the add route. It is a React component that is rendered when the user navigates to /add. It contains a form that allows the user to add a new notification. When the form is submitted, the handleSubmit function is called, which sends a POST request to the server with the notification data.
- Establishes a WebSocket connection using io(‘http://localhost:4000’) via useMemo.
- Uses useEffect to handle connection events and attempts to reconnect in case of errors.
- Creates an Express server and a Socket.io server.
- server.js is the file that will handle the POST request from the client and emit the notification to the client.
- Handles WebSocket connections and updates in real-time.
- Logs user connections, emits initial data, and updates data on send notification.
