Socket.IO vs WebSockets: Which One Should I Use?

What are the main differences between Socket.IO and WebSockets?

Socket.IO is a library that provides a higher-level abstraction over WebSockets, offering features like automatic reconnection, event handling, and fallback options. WebSockets, on the other hand, is a protocol that allows for full-duplex communication over a single TCP connection.

When should I choose Socket.IO over WebSockets?

You should choose Socket.IO if you need features like automatic reconnection, support for older browsers, or if you want to use its built-in event system. If you need a lightweight solution with minimal overhead, WebSockets might be the better choice.

Are there any performance differences between the two?

In general, WebSockets can be more performant due to their lower overhead, but Socket.IO provides additional features that can be beneficial depending on your application's needs.

Can I use both in the same project?

Yes, you can use both in the same project, but it’s important to manage the connections properly to avoid conflicts.
