Implementing a Single Refresh with Effect Primitives
What Effect primitives would I want to use for this:
I store value x in some ExternalStore
I have an effect
I have another effect
I want to be able to call
I store value x in some ExternalStore
I have an effect
ensureValueFreshness that checks if that value is "stale", and if so, requests a fresh value from an external service and write the new value to the store.I have another effect
getFreshValue that returns the current value if it is fresh, if it's stale, it triggers a refresh, returning the new value.I want to be able to call
getFreshValue many times, with only a single refresh happening, and all subsequent requests waiting for the result of the pending refresh
