knockout-decorators - npm Package Versions

[0.8.0] - 2017-01-22

Added

• subscribe(() => this.observableProp, (value) => { ... }) function

Changed

• @extend decorator now can be combined with @computed decorator

Removed

• @subscribe decorator
• @reaction decorator

Native ko.computed with side effects can be used in all places where we use @reaction or @observer decorator.

In v0.7.1 and earlier @subscribe decorator can be used only with @observable but not with @computed. To avoid this restriction we can create ko.pureComputed and subscribe to it:

class ViewModel {
  @computed get computedProp() { ... }

  constructor() {
    ko.pureComputed(() => this.computedProp).subscribe((value) => { ... });
  }
}

So from v0.8.0 instead of @subscribe decorator there is shorthand function subscribe with some extra functionality like "subscribe once":

class ViewModel {
  @computed get computedProp() { ... }

  constructor() {
    subscribe(() => this.computedProp, (value) => { ... });
  }
}
