I have tried import babylonjs in react but its is not working. Does any body know how to import and use the babylonjs in reactjs application.
Thanks.

Answer 1

Not sure if you have found the answer on your own, however there are several ways now as babylon has matured. There is actually a Node package for using babylon.js with react here: https://www.npmjs.com/package/react-babylonjs
Also there is an install guide for React in Babylon.js in the docs:
https://doc.babylonjs.com/resources/babylonjs_and_reactjs
Hope that helps!

Babylon JS is available as npm package. You can easily build a simple React Component around a canvas and Babylon JS
I have created a minimal example with React+ Babylon:
