@Mayhem93 Yes that's there about the large community, but I'm sure once you start scaling you'll come to know NodeJs is shit 😝, i had to rewrite the backend for our Realtime IoT micro service architecture.
No doubt NodeJs will be able handle your I/Os but if u start doing any minor processing you'll get poor performance and lags. Golang can handle more I/Os than NodeJs and also highly scalable and highly concurrent. When processing realtime data u need multithreading. We used a similar stack as yours. You could try Influx Db instead of elastic search 😛 . I would use nodejs only for Apis 😉. Well you can disagree with my inputs based on your use case.😈Are you using Aws services for the deployments?

@Mayhem93 why are you writing the backend in NodeJs?

Beware of Null Pointers 😈

Would have worked if it was written in a native language like Golang :P
I have worked in all the technologies you have used.
I don't like JavaScript :P
The architecture looks great for real-time use case
