Rewrite part of the site to react / redux?

Question

JavaScript

Good afternoon! I have the following question...
There is a site written in php and js/jquery, and there is a part of it that is frequently updated (every five seconds), it turns out that it does not work very well.
And here is the question:
1. Please tell me if it is possible to rewrite this part of react / redux, will it be necessary to write a separate server for this?
2. Will it be possible to use this code for a mobile application (react native) so as not to duplicate it?
I don’t have much experience with react / redux, but there is time to study and understand this, the main thing is to do it right and with high quality.
I would be grateful for any help / advice on how to implement this.

Answer 1

React is great for this. Replacing some "page" from the entire site - that's it.
Of course, for this, it will be necessary that the server has a REST API (if it is already, then you don’t need to write a “separate” server, and if not, you still don’t need to, but you will have to write a “separate” piece in which this will be implemented API).
You will most likely be able to use react native too, but I wouldn’t set it up so “rosy” right away, because you will have to tinker with the code, in any case, what will be written on the backend will already come in handy for a mobile application on any tool.
