Frequently asked questions

What does WebSocket enable servers to do regarding data transmission?

WebSocket allows servers to push data to clients. It’s used for real-time applications (chat, gaming, live updates).

How does a WebSocket connection initially establish itself before transitioning to the WebSocket protocol?

WebSocket starts as HTTP, establishing an initial connection using standard web protocols. It then upgrades this connection to the more efficient WebSocket protocol.

What are the key differences between REST and GraphQL approaches to data retrieval?

REST (Representational State Transfer) typically uses multiple endpoints with fixed data structures, while GraphQL allows clients to specify exactly what data they need from a single endpoint.
