When should I use Server-Sent Events?

What are Server-Sent Events and when should I use them?

Server-Sent Events (SSE) are a way for servers to push real-time updates to web clients. You should use them when you need a one-way communication channel from the server to the client, like live notifications or updates.

Can you give me an example of where SSE would be beneficial?

Sure! SSE is great for applications like stock price updates, where the server continuously sends new prices to the client without the client needing to request them.

Are there any limitations to using Server-Sent Events?

Yes, SSE only supports one-way communication from the server to the client. If you need two-way communication, consider using WebSockets instead.

How do I implement Server-Sent Events in my web app?

To implement SSE, you can use the EventSource API in JavaScript to listen for messages from the server. On the server side, you need to set the correct headers and send data in a specific format.
