Select a subset of props

[HyruleGG]

Hey, I'm new to Elf and had no luck finding an answer to my question here or in the docs.

I have an Elf Store with a couple of props. Out of that pops, I would call the same method upon every change happening on a subset of that props. Should I maybe just crate an own Store for that subset to solve my problem?

Right now, this is what I would do...but its not cool to have multiple subs - would be nice to just hand over an object or array with the subset of props that I am interested in.

userSettingsStore.pipe(select((state) => state.noiseSuppression)).subscribe((state) => {
   console.log('Call the same method... ', state);
});
userSettingsStore.pipe(select((state) => state.echoCancellation)).subscribe((state) => {
   console.log('Call the same method... ', state);
});
    

As I said, maybe I should split my props into different Stores or I nest the subset of props to be able to filter them directly?

Changed now the structure, this works pretty well (the subset is now nested in mediaStreamConfig) - however I still think it could be really useful to query for a subset of props 😅

    userSettingsStore.pipe(select((state) => state.mediaStreamConfig)).subscribe((state) => {
      console.log('Subset', state);
    });

You can create a custom operator that handles this.
