how we can use node js and angular js in our outsystems application?

I wanted to use node js in our outsystems. Is there any possible situation where we can use Node and Angular?. If exists please tell me how and where can we apply  


both are possible, 

however angular is a bit weird, because you can do most stuff with outsystems.

(unless you want to have outsystems as a pure REST-server)

how you can apply it is more what you want to achieve and how does the architectural-picture looks like.

and chances are it's specific for your case, so not much help we can off there imho.
