@ngrx/effects fires same request twice #1190
Description
Minimal reproduction of the bug/regression with instructions:
There is a similar issue closed with indication 'works as designed', but it appears not to work that way at least on my end.
Here's a reproduction of the issue:
https://stackblitz.com/edit/angular-gfh6pn
One remark regarding throttle operator in the effects - if commented out, effect fires POST request, cancels it immediately, then fires pre-flight and POST again.
With throttle, there are no cancelled requests, but both pre-flight and POST are duplicated.
In the similar issue closed there were a couple of suggestions to tackle this behavior:
- use .share() - does not help the issue in my case
- avoid importing EffectsModule.forRoot(), but provide effects class in providers array - does not work at all, effects are not evaluated
- avoid double subscription, which I seem not to have in my case
Expected behavior:
pre-flight request followed by an actual request each time action is triggered, no duplicated requests
