I have been an active Ionic user since v1, though never actually posted on the forums.
I wrote a tutorial on how to use Ionic with PlayCanvas, a WebGL engine.
PlayCanvas provides a great framework to author and deliver 2D/3D/VR web experiences.
Ionic provides a great tool for UI and an awesome UX through its components.
Let me know if you find this useful! The tutorial references a template project as well for anyone interested in replicating this.
