@mauriciovigolo thank you! looks similar to what i had in mind. just dont forget to remove it from package json. since your still on v20 with this branch all your tests will fail unless you add provideZonelessChangeDetection() with the test modules. not sure if this is necessary with v21.

It cannot be removed (rxjs) from package.json because other parts of the code still use it.

The library doesn’t have zone.js as a peer dependency, so I just removed it from the code. This change is also planned for v21.
Thank you for the input and contributions, @rOBloOm!

I won’t remove rxjs as a peer dependency; I only removed it from that specific code.
Thank you, @badinmichal!
