Hey @TomF I think @Rakesh_JS is referring to the Server-Sent Events capabilities standardized as part of HTML5. Solace Event Brokers don’t currently support SSE, but I’d love to hear more about your use case for using them @Rakesh_JS . We usually direct folks towards using MQTT over websockets since it’s still lightweight while also allowing for bi-directional communications which is a shortcoming of SSE.
There is a short comparison of SSE & MQTT here: MQTT vs SSE: A Comparison | IoT For All
*Note we also have a JavaScript SMF API which allows for more use of solace broker features.
