Observable (goori-soft)

Extensible class for observable objects

Install

$ npm install @goori-soft/observable

How to use it

To use this class properly you must extend it into another class. Your class will inherit the observable properties.

const Observable = require('@goori-soft/observable');
class MyClass extends Observable{
    myPorp = ''

    setProp = (data)=>{
        this.myPorp = data;
        this.notify(this.myPorp);
    }
}

This class is liable to be observed. The observer must be a function capable of handling the parameter passed on by notify.

Note: if notify is invoked without parameters, the first parameter to be passed on to the observer will be the 'this' object.

const myObj = new MyClass()

const myObserver = (data, obj)=>{ console.log(data); }

myObj .subscribe(myObserver) .setProp('Johnny');

Whenever the setProp method is invoked, the observer will be notified.
