Tiny Observable pattern implementation for creating observable properties

Installation

Npm:

Usage

View1.ts:

export class View1 {
    public readonly buttonClicked = new Observable<ClickEvent>()
    public readonly textChanged = new Observable<TextChangedEvent>()
    
    // Do something internally to handle UI events 
    
    private handleButtonClick(e: ClickEvent) {
        this.buttonClicked.notify(e)
    }
}

View2.ts:

export class View2 {
    private sampleView: View1
    
    constructor() {
        this.sampleView = new View1()
        this.sampleView.buttonClicked.subscribe(this, this.onSampleViewButtonClicked)
    }

    onSampleViewButtonClicked(e: ClickEvent) {
        
    }
}

Observable properties:

const nameProperty = new ObservableProperty('John')
nameProperty.changed.subscribe(this, this.onNameChanged)

nameProperty.value = 'new name'
