Can I integrate React into a Knockout JavaScript app?

June 5, 2022

I’ve been building an application in my spare time, its backend is C# and I use Knockout js for the front end, to be honest its an app I use out side of my main job for learning purposes etc, I may launch it one day not really sure. I’ve now a new job where they use React, so my question is can I now integrate React into my app so I can begin learning this library? I’d aim to keep each component separate but does anyone think this a bad idea mixing libraries like this? I haven’t learnt React yet hence I want to start integrating it into my side project though I don’t really want to start rewriting all the Knockout JavaScript again also.

>Solution :

A React app can be initialized on any DOM node you want. Pick a page you want to put React on, create a DOM node (a simple div) and create a Element on that node.
