Previously, most AR development would need to be done on a native installed app. Except, with the advent of ARCore, Google has added support for AR development on the web, which, allows users to access AR applications through a browser. Of course, AR web applications may never be as robust or feature rich as a similar app done with Android or Unity. Yet ARCore extends its browser support to include iOS as well as Android. So if you need a cross-platform AR app, then you likely want to focus on ARCore web development.

In this chapter, we continue our work of setting up our environment for ARCore web development. Listed here are the main topics we will cover in this chapter:

• Installing WebARonARCore 
• Installing Node.js
• Exploring the samples
• Debugging web apps on Android
• 3D and three.js

Even if you have no interest in web development, you should still review this chapter. We will be using elements from this chapter in the final project, Chapter 10, Mixing in Mixed Reality.
