...Examples are included for creating weighted objects, levers, dials, guns, and more. Supports HTC Vive, Oculus Rift, Windows Mixed Reality, and more. Extensive plugin system to do custom logic on interactions and grab events. See the package directory for package details, quick start instructions, and tutorials.
Build virtual reality experiences with A-Frame and React
...I recommend using vanilla A-Frame and aframe-state-component with static templating over aframe-react. React wastes a lot of cycles and incurs a lot of memory garbage. aframe-react is often abused where it is too easy to place 3D/real-time logic at the React layer, causing poor performance (e.g., doing React renders on ticks). aframe-react applications frequently ignore the prescribed ECS framework of A-Frame. Internally, React does tons of computation to compute what changed, and flushes it to the entire application. It is apparent React ecosystem does not care much about memory as most examples allocate functions and objects in the render method, and where immutables are popular.
