Server-Sent Events (SSE) are commonly used in real-time applications where the server needs to push updates to the client.

Here are a few use cases:

1. Real-time notifications: SSE can be used to push notifications to the client in real-time. For example, in a social media application, the server can push notifications about new posts, likes, comments, etc.
2. Live news updates: In a news application, the server can push live news updates to the client.
3. Real-time analytics: In an analytics dashboard, the server can push real-time data updates to the client.
4. Chat applications: In a chat application, the server can push new messages to the client in real-time.
5. Online multiplayer games: In an online multiplayer game, the server can push game state updates to the client in real-time.
6. Stock price updates: In a stock trading application, the server can push real-time stock price updates to the client.
