You don't need React (or other frontend framework)

I cannot count the amount of times I have people asking about how to integrate Django and React and then struggling with various issues from CORS headers, authentication, static files and deployment to name just a few. These issues are not too hard to deal with by themselves assuming you have a firm grip on Django itself, but typically it seems that these questions are asked by those doing their first or second project in Django.

My advice is this, when learning a new technology, library or framework, learn it in isolation from other technologies and understand everything it provides before mixing in other technologies. In the case of Django and React, Django provides HTML templating which while not being quite as in demand as React does provide a frontend without the huge complexities that come with using React. Essentially build a few sites using just Django and then start adding React if you need it.

A final note, if you learnt React and want a fully functional framework to build your webapp, then I would first consider Next.js or Remix, both of these are a closer comparison to Django in what they offer out of the box but use React as a foundation which will lead to a simpler, cleaner developer experience overall.
