Hi and welcome!

It possible to create NPR graphics using Blender's shader nodes. See for example

You can ask a question on how it was done from the author of Blender Lounge.

Hello, I'm not good at English , first of all ,thanks for your efforts. And i wish the B4W support Edgedectection,
including some options such as width/color/transparency even customize stroke. I think those features are very important in toon shading (NPR). Thanks!
