What are the limitations of SSE?

There are two key limitations to SSE. First, it is server-to-client only and hence does not address the request streaming use case—e.g., streaming a large upload to the server. Second, the event-stream protocol is specifically designed to transfer UTF-8 data: binary streaming, while possible, is inefficient.

How do SSE events work?

Through this interface a client requests a particular URL in order to receive an event stream. SSE is commonly used to send message updates or continuous data streams to a browser client. In a nutshell, a server-sent event is when updates are pushed (rather than pulled, or requested) from a server to a browser.

Where are server-sent events used?

They are commonly used to send message updates or continuous data streams to a browser client and designed to enhance native, cross-browser streaming through a JavaScript API called EventSource, through which a client requests a particular URL in order to receive an event stream.
