Does node, as the middle tier, send requests to the back end and receive browser requests more often?

excuse me, is there a big god who is proficient in using node to do the middle platform?
is it using koa?
how does it feel and how does the effect compare with before?
if I want to learn, do you have any documents that you can recommend? Or a case!

just make Mini Game node as the middle tier and send the final result to java
see that your business needs make nothing more than the background tasks to reduce the advantages of node.
