Should I use ngrx-data, if the content-type I'm receiving is JSON-LD + Hydra?

I love the advantages of JSON-LD, Hydra and just found out about NgRx/data.

I tried using it without customization, which obviously didn't work. Today I spend some hours on the documentation, which left me with even more question.

The important part is, that I don't want to sacrifice any information about the collection. So I can't just use custom Effects.

Any idea on how to approach this?

I see one way to do this :

1. Add "@" properties to your models :

export interface HydraEntity {
    '@id': string;
    '@type': string;
}

export interface Author extends HydraEntity{
    id: number;
    name: string;
}

2. Change the way Ngrx/data handle API responses adding the additional "hydra:*" fields : https://ngrx.io/guide/data/entity-metadata#additionalcollectionstate

You should be able to reduce your result in your state.

I never tried it but I assumed it following this issue: https://github.com/ngrx/platform/issues/1948
