Cannot find namespace NodeJS when using NodeJS.Timer in Ionic 2

I am attempting to use some code I found on https://github.com/bevacqua/dragula/issues/289#issuecomment-277143172 to my Ionic project.

When I run the code I get an error Cannot find namespace 'NodeJS' and the error refers to touchTimeout: NodeJS.Timer;

How can I adapt the code below to make the NodeJS.Timer line work?

import { Directive, ElementRef, HostListener } from '@angular/core';

@Directive({ selector: '[delayDragLift]' })
export class DelayDragLiftDirective {

dragDelay: number = 200; // milliseconds
draggable: boolean = false;
touchTimeout: NodeJS.Timer;

@HostListener('touchmove', ['$event'])
// @HostListener('mousemove', ['$event'])
onMove(e: Event) {
if (!this.draggable) {
e.stopPropagation();
clearTimeout(this.touchTimeout);
}
}

@HostListener('touchstart', ['$event'])
// @HostListener('mousedown', ['$event'])
onDown(e: Event) {
this.touchTimeout = setTimeout(() => {
this.draggable = true;
}, this.dragDelay);
}

@HostListener('touchend', ['$event'])
// @HostListener('mouseup', ['$event'])
onUp(e: Event) {
clearTimeout(this.touchTimeout);
this.draggable = false;
}

constructor(private el: ElementRef) {
}
}
