TopicsServer-Sent Events
Part of the Full Stack Developer Roadmap.
Summary
A simpler one-way protocol (server-to-client only) for pushing live updates over HTTP — a lighter-weight alternative to WebSockets when your frontend just needs to receive updates, not send them.
How to Learn This
- 1Build an SSE endpoint on your backend and consume it in React with `EventSource`.
- 2Compare SSE's simplicity to WebSockets for a use case like live notifications.
- 3Learn SSE automatically reconnects on the client side, unlike raw WebSockets.
