- Hear directly from one of the CAP team members, David Kunz, about best practices as they apply to designing and building CAP applications with Node.js. More information: github.com/SAP...
Hi David, your presentation is awesome! Very good content and examples, looking forward for a sequel to this!
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.
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!)
What software did David use for the slidedeck? Code based?
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]
This is gold!
Great job 👏
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?
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.
@@devonduty Thanks!
Very great explained. Thx
You're welcome! [dja]
How to handle the parallel request in sap cap node js
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.
