Server-Sent Events vs WebSockets
Learn how Server-Sent Events provide one-way real-time streaming, how they compare to WebSockets and long polling, and when to choose each technology.
Another Real-Time Option
WebSockets are not the only option. Server-Sent Events (SSE) give a simpler, one-way streaming channel from server to client over plain HTTP.
What Are Server-Sent Events?
SSE pushes a continuous stream of text events to the browser over one long-lived HTTP connection, received via the EventSource API. It is one-way only.
