How to set up a pinia store to wait for the state

[entioentio]

I have a (composition) store that is used in s couple of modules, they are unaware of each other and can be initialized in the same moment as well as at different times.

The store retrieves data from an API and saves it in the state. All of the modules execute the store's fetchData method, all of them await a promise it returns.

The problem is that when the modules are initialized at the same moment, both perform fetchData resulting in two requests fired. The ideal situation would be to

1. Allow only one request being fired (that's pretty easy to do, just save the request state in a ref, f.e. "pending")
2. Export the state as a promise, so that the module awaits the state to be loaded from an API, receiving it's data only thereafter.

Those with a requirement that the modules are unaware of the store implementation - the less code on their side the better.

How do you handle such cases?

Is a there anything wrong with this approach? If not - how to implement it?
