"Hi, we have here a Gradle-Multi-Project, it seems to be working currently in the bower compatibility mode with latest vaadin-14.X.rc. However, I am not sure how do I migrate it to npm. Any Tips would be really appreciated. Apparently, there is no vaadin-gradle plugin that takes care of genrating npm files as mention in :“2.1 Add front-end plugin”
It would be great for if you could mention what files and where they should be existed so that the npm works. I am not using any vaadin-gradle plugin uptill now and do not require do so."
Like Aziz Rehman, I build Vaadin projects with gradle and without any specific vaadin-gradle plugin.
How to build Vaadin Spring boot app in the npm mode without any plugin ?
