Is SWR the correct library for me?

Hi All,

Simple question here but I'm not sure I understand if SWR does what I need it to do.

I'm after a simple data fetching library for use in a create-react-app (not next.js) for grabbing data on page transition. I was going to use "async react" which looks like a great library but SWR seems to have many more downloads and has been updated recently and often.

However, after installing it I noticed that after fetching the initial data it keeps making repeat calls to get fresh data - when you switch tabs and sometimes for no particular reason. Also, if it fails to get data it keeps trying. Now, I can see that it's possible to switch all of these behaviours off individually but am I going against the grain here? Is SWR designed for a use case I don't understand?

I do have some scenarios when I do need a call to be retried, e.g. when the user's security token changes. Each time I make a call to my API I need to intercept the call and check if the token is still in date, if it isn't then I need to cancel the call and ask the user to log in again. Once they have and the new token is put into redux I need all cancelled calls to retry, but just once.

I also need to post/patch data to the back end as often as I need to fetch data. This is a CRUD app.

Is what I'm trying to do possible or is SWR a tool for a different job?

Many thanks.
