ReactJs with Grav

We want to start using Grav for a portal. What do you think about using ReactJs instead of Twig ? Advantages/disadvantages, easy/complicated, experiences, it is against Grav architecture ? Thanks for all the answers.

I've used it on some pages of a test project with Grav. I used a plugin called Grav Pages as Data to return the page data as JSON and then it made it pretty easy to work with in React.

I used React in combination with Twig. Just for a couple widgets and page functionality. I'm sure you could use React by itself with Grav as the backend CMS, but I've never done so.

Hope that helps!
