signals

Information

I was trying out the new feature from Angular 21 and wanted to use it with ngrx signal store. However, I realized it is impossible to use it in the signal forms submit function because it requires a promise in return, but rxMethod returns only a destroy. Therefore, we need a function that returns a promise instead.

In this article I explained the issue and created a new method called rxPromiseMethod to be used instead of rxMethod within withMethod(). You can find some examples there.

Describe any alternatives/workarounds you're currently using

There is a withMutation function from the @angular-architects/ngrx-toolkit library, but the issue is that you can only send a payload to it, and the types are tightly coupled with the HTTP request DTO, which is not good.

I would be willing to submit a PR to fix this issue
