Can you clarify whether you mean if you are building a real time system? That is one that has hard latency requirements: https://en.m.wikipedia.org/wiki/Real-time_computing

Or do you mean an event driven web based system? The term realtime has become overloaded and your answer changes the challenges… a lot.

Thanks for asking! I mean the latter: an event-driven system where users and devices can send reactions/chat messages and these are displayed as updates in realtime.
