A React component for viewing an STL object from a given URL by utilizing Three.js
See a live demo here.
Note that you will still have to abide by the rules of CORS so you won't just be able to load a 3D file from someone else's site
npm install stl-viewer
import STLViewer from 'stl-viewer'
<STLViewer
url='http://www.example.com/example-url.stl'
width={400}
height={400}
modelColor='#B92C2C'
backgroundColor='#EAEAEA'
rotate={true}
orbitControls={true}
/>
