Use SubSink to Unsubscribe automatically

SubSink

import { Injectable, OnDestroy } from '@angular/core';

/**
 * @description Keeps hold of your subscriptions and unsubscribes them when component is destroyed.
 * This uses 'SubSink' library to achieve this.
 * @usage Extend your component from this 'MyComponent extends Unsubscribe'. Call super() in your component's constructor.
 * @important Please keep a note that if you happen to implement OnDestroy in your component,
 * you have to explicitly call super.ngOnDestroy() to invoke un-subscription for the component.
 * @param sub; Subscription list. Assign your subscriptions in your component to 'sub'
