Angular left tooltips

Angular pop over component that appears to the left of a button on user hover.

Examples

For this component to properly work, you will need to install @popperjs/core into your project. Please run the following:
npm i -E @popperjs/[email protected]

import { Component, AfterViewInit, ViewChild, ElementRef } from "@angular/core";
import { createPopper } from "@popperjs/core";

@Component({
  selector: "app-root",
  // templateUrl: './app.component.html',
  template: `<div class="flex flex-wrap">
  <div class="w-full text-center">
    <button #btnDropdownRef (mouseenter)="toggleTooltip()" (mouseleave)="toggleTooltip()" class="bg-pink-500 text-white active:bg-pink-600 font-bold uppercase text-sm px-6 py-3 rounded shadow hover:shadow-lg outline-none focus:outline-none mr-1 mb-1" type="button" style="transition:all .15s ease">
