What are the best practices for implementing SSE in production?

When implementing Server-Sent Events (SSE) in production, consider the following best practices: 1. Use a reliable server that can handle persistent connections. 2. Implement reconnection logic on the client side to handle network interruptions. 3. Optimize the data sent to minimize bandwidth usage. 4. Ensure proper error handling and logging.

How do I handle reconnections effectively?

To handle reconnections effectively, you can implement an exponential backoff strategy. This means that after each failed attempt to reconnect, you wait a progressively longer time before trying again. Additionally, keep track of the last event ID sent to the client, so you can resume from where the connection was lost.

What are the limitations of using SSE?

Some limitations of SSE include: 1. It only supports one-way communication from server to client. 2. It may not work well with older browsers. 3. It can be less efficient than WebSockets for high-frequency updates.

Can I use SSE with load balancers?

Yes, you can use SSE with load balancers, but ensure that they support sticky sessions or session persistence to maintain the connection between the client and the same server.
