Unused patched operator in ./src/rxjs.imports.ts: switchMap

[cartant]

Be ware that this gotcha can effect false positives for unused patches. Similarly, if the observable instance to which the patched operator is applied is not typed as an Observable the static analysis will not consider it to be a use of the operator.

switchMap is not an alias, so this is unrelated to any flatMap issue.

Thank you for clarifying this:

Similarly, if the observable instance to which the patched operator is applied is not typed as an Observable the static analysis will not consider it to be a use of the operator.

This was NOT appended to Observable, but an Angular library object.

I am closing this.

I should have said that the type needs to be Observable or an Observable-derived type. The real problem is when patched operators are used with values that have any as their type. The static analysis won't consider them to be observables.

What was the Angular object that effected the unused error? If it's not any, what is it?

@cartant It was a paramMap from a ActivatedRoute
