Using redux with SSR

[boreal willow]

I am trying to understand why i need to use makeStore instead of configureStore func to create redux store. I have read the doc https://redux-toolkit.js.org/usage/nextjs#introduction, but i still dont understand why we need "Per-request safe Redux store creation". Could anyone give me an example of potential issue that would occur if i wont use makeStore?

Per request store is important to avoid sharing data between requests on the server. This could lead to data leak without it

Am i right that it makes sense if there is no authorization feature? Because i cant imagine a case where two different authorized users would get the same data (for example the data that is related to the first user) from the redux store. Or I have a misunderstanding about how it works :((

It is worth nothing that i am using nextjs only for frontend and my backend is an external php project. All the requests in my app are the REST API calls with axios lib

Nope, you could leak on the server (by share the same JS object) between two authenticated user

if you do const store = configureStore({}) you are sharing the same object for all requests
