We are planning to develop a Mindsphere app and decided to use AngularJS (6or 7) or ReactJS as front-end framework. Can anyone put some light which framework should be better choice from Mindsphere (or IOT) point of view.
Does Mindsphere advocates any front-end framework for app development.
From an end-user perspective (I'm not part of the MindSphere team), I don't think it matters much, the web part is pretty agnostic about the framework you use. There's been questions in these forums about both of them, doesn't seem there's been blocking issues with either of them.
My two cents: I've seen more code written in Angular around MindSphere, also internally in Siemens, so you might get better support / more experience with it.
