How to create store events and handlers external to the store

[st-clair-clarke]

Hi,
I have been attempting to create a store event handler external to the store but it always results in circular refeference.

Could you please update the Store Events page on how this maybe done. I do see warnings at least twice about circular references, so it seems others might be having the same issue. Thanks

NB. I would like to create the events and handlers external to the store just to reduce cluttering in the store.

Cheers

Registering an Event and a handler outside the stores is well-supported and should generally not introduce any circular reference error.
Check out the following stackblitz: https://stackblitz.com/edit/signalstory-discussion-91?file=src%2Fmain.ts

What could introduce a circular reference, are reflexive or transitively looping event handler relations:
You publish EventA and EventAHandler1 publishes EventB whereas EventBHandler1 again publishes EventA => Infinite Loop.
This can get quite complicated to track if you have a large chain of events, for example, if EventA leads to EventB, leads to EventC, leads to EventD , and so on, which finally leads back again to EventA being published.

If it really is the registration that causes all of this for you, could you post some code to troubleshoot?
