@metapins/aframe-element

aframe-element is a library inspired from the very nice library Polymer lit to map A-Frame AR / VR / 3D elements on typescript classes like Angular/React/Lit.
Used with @metapins/lit-observable, you can create simple, fast and reactive WebXR 3D /AR and VR scenes with all modern web development good practices.
