I think i will use websockets, thanks for the advice. At moment i'm using callbacks only because can't do different.
Probably async/await will be available from the next version (I've read that too).
Using NodeBB v0.7.x on Openshift
When v0.7.x was released, NodeBB can no longer work on Openshift - it will repeatedly crashes. So I decided to find a workaround for it. Looks like I had, and it can be possible to use v0.7.x on Openshift, though installation steps will be different! I actually feel like install guide for v0.7.x on Openshift will be simpler and easier to understand.
I'll create a pull request once I try a clean install on Openshift.
(Sorry if posted in wrong category!)
I'm starting this right now. Stay tuned!
I'm finished! The pull request is at https://github.com/NodeBB/nodebb-english/pull/46
If in case NodeBB didn't merge my pull request.
