I'm not super sure what would be the best approach for this.
I have a
I would like to fetch it one time and check if there's any sort of data already in the client, then there's no need to fetch again. How would I approach this problem?
I have a
NextAuth application that fetches an access token and I then use the access token to access data from an API. What would be the more ideal way to persist data from the API, so I don't need to do unnecessary fetches and store it locally on the user's client? Do I store it on next-auth? Do I store it on localStorage? I would like to fetch it one time and check if there's any sort of data already in the client, then there's no need to fetch again. How would I approach this problem?

Is this the conventional way to approach this? How did people cache the data before this package?
most people store the cache in redux state before react-query exists

Ah, I see! What about
localStorage? Is this used for something else? I'm trying to see what was the approach used with just HTML, CSS and JavaScript and I'll be done with this thread.if you store in localstorage, how do you know if the data has changed?
