Some questions about reactjs json api?

Question

JavaScript

Greetings toasters!
The application that I am developing is built on server rendering, but there is a page by the type of catalog navigation (selection by tags, sorting, search), I want to make it with dynamically changing elements, for the convenience of the user. I installed the assembler with react, remembered the life cycles of react hooks, everything seems to work at the front. It's time to write the server side.
So the question is, is there a need for security tokens to communicate via json with the server, and there are no PUT, UPDATE, DELETE operations at all, only GET, and then there can be 3 or 4 routes in total.
I'm doing it on Django, here I also pay attention to www.django-rest-framework.org, which is actually intended for building RESTful, but is it worth pulling it to cover current tasks, how monstrous is it, I can only guess?
