Best Practices for CAP Node.js Apps

[@jhodelcailan1703]

Hi David, your presentation is awesome! Very good content and examples, looking forward for a sequel to this!

[@MrStijnMe]

It is hard to find good education/books on JavaScript, CAP, ... This because all tools are still constantly (and fast) evolving with new developments.I learned several usefull stuff, even from commands I already knew but never used in this way! I can REALLY recommended to watch this presentation a few more times. 👍(and yeah, I immediately subscribed to David's channel!)

I was amazed!! Thank you so much David , yes all it needs replay.... again and again and learn out of this video. Just a quick question coming to my mind, can we have similar sort of things on Java as well, if possible.

What I dont understand is that at 17:06 David mentions that you should not use cds.tx() without a req object. Then at 22:06 he uses cds.tx() with no req object. I realize that the req object of express cant be the req object of CAP. Since that is the case, what kind of req object can we use?

[@devonduty]

Hi Hamza, Thanks for the question! You can use cds.tx() without any arguments, but then you have to take care of the COMMIT/ROLLBACK yourself. In a custom express middleware you have no suitable req object, therefore you either perform the COMMIT/ROLLBACK manually or provide a function in cds.tx (we then take care of the COMMIT/ROLLBACK), both options are shown in the presentation.

What software did David use for the slidedeck? Code based?

[@sapdevs]

Hey there, it was based on reveal.js - an excellent presentation-as-code mechanism that I've also used myself. Slides created in Markdown. See revealjs.com/ for more details. Cheers. [dja]

How to handle the parallel request in sap cap node js

[@sapdevs]

CAP Node.js uses the Express module for web request handling. Between the event based, non-blocking processing model in Node.js and the Express handler framework, parallel requests are handled and managed automatically. Nothing you need to do in addition.
