deep-observables

Installation:

npm install @applied.math.coding/deep-observables

Basic usage:

Assume you have three class declarations A, B and C.
Moreover, assume they do referrence each other like below.
If you want to have the values from such nested classes automatically updating on changes, you
may use the annotation '@observed' and ensure to call the method 'changeEntity'
with corresponding type and new value.

import { changeEntity, fromJson, observed } from 'deep-observables';

class C {
  id: number;
  d: boolean;
}

class B {
  id: number;
  p: number;
  q: number;
  r?: {
    rr: number;
  }
  @observed(C)
  c?: C;  
}

class A {
  id: number;
  p: string;
  @observed(B)
  b: B;
  @observed(C)
  c?: C;
}

const o = fromJson<A>({
  id: 0,
  p: '',
  b: {
    id: 0,
    p: 5,
    q: 1
  }
}, A);

o.p = 'hello';
o.b.p = 9;
changeEntity(B, { id: 0, p: 7, q: 2 });

Note

Array types are not supported at the moment.
The library is of pure experimental nature!
