Auto growing textarea in ionic

Issue

I am trying to add an autogrowing textarea to my app but for some reason it is not working. The module that I am using is https://github.com/tagged/autogrow (it was recommneded on the ionic forum)

Solution

I wrote a very simple directive that works with Ionic 2 and ion-textarea. Here it is:

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

@Directive({
selector: "ion-textarea[autoresize]" // Attribute selector
})
export class Autoresize {
  @HostListener("input", ["$event.target"])
  onInput(textArea: HTMLTextAreaElement): void {
    this.adjust();
  }

  constructor(public element: ElementRef) {
  }

  ngOnInit(): void {
    this.adjust();
  }

  adjust(): void {
    let ta = this.element.nativeElement.querySelector("textarea");
    ta.style.overflow = "hidden";
    ta.style.height = "auto";
    ta.style.height = ta.scrollHeight + "px";
  }
}
