解决方案

I would create dedicated component like clap

But first you need to add mojs to your page

<script src="https://cdnjs.cloudflare.com/ajax/libs/mo-js/0.288.1/mo.min.js"></scrip>

Since we don't have typings for mojs you can just define it as any:

declare let mojs: any;

(Note: you can create typings something like How to extend js class from outside library in TypeScript / Using mojs in TypeScript if you want)

Now it's time to create our custom component.

We're going to use ViewChild instead of document.getElementById to hold of reference to DOM element. For that we need to put template references on elements (<button #clap). We will use that references instead of selectors like el: '#clap--count-total', so our component will be scope safed

Also we won't listen to dom events through .addEventListener but rather via element output events like (click)

So here's the code

clap.component.html

<button #clap class="clap"
     (click)="repeatClapping()" 
     (mousedown)="onClapMouseDown()" 
     (mouseup)="onClapMouseUp()">
  <span>
    <svg [class.checked]="clapIconChecked" ...>
      ...
    </svg>
  </span>
  <span #clapCount class="clap--count">+{{currentClaps}}</span>
  <span #clapCountTotal class="clap--count-total">{{claps}}</span>
</button>

clap.component.ts

import { Component, ElementRef, Input, OnInit, ViewChild, EventEmitter, Output } from '@angular/core';

declare let mojs: any;

@Component({
  selector: 'clap',
  templateUrl: './clap.component.html',
  styleUrls: ['./clap.component.css']
})
export class ClapComponent implements OnInit {

  @Input() claps = 0;

  @Input() tlDuration = 300;

  @Output() clapsChange = new EventEmitter();

  @ViewChild('clap') clapEl: ElementRef;

  @ViewChild('clapCount') clapCountEl: ElementRef;

  @ViewChild('clapCountTotal') clapCountTotalEl: ElementRef;

  currentClaps: number = 0;

  clapIconChecked = false;

  private animationTimeline: any;

  private clapHold: any;

  ngOnInit() {
    const triangleBurst = new mojs.Burst({
      parent: this.clapEl.nativeElement,
      radius: {50: 95},
      count: 5,
      angle: 30,
      children: {
        shape: 'polygon',
        radius: {6: 0},
        scale: 1,
        stroke: 'rgba(211,84,0 ,0.5)',
        strokeWidth: 2,
        angle: 210,
        delay: 30,
        speed: 0.2,
        easing: mojs.easing.bezier(0.1, 1, 0.3, 1),
        duration: this.tlDuration
      }
    });

    const circleBurst = new mojs.Burst({
      parent: this.clapEl.nativeElement,
      radius: {50: 75},
      angle: 25,
      duration: this.tlDuration,
      children: {
        shape: 'circle',
        fill: 'rgba(149,165,166 ,0.5)',
        delay: 30,
        speed: 0.2,
        radius: {3: 0},
        easing: mojs.easing.bezier(0.1, 1, 0.3, 1),
      }
    });

    const countAnimation = new mojs.Html({
      el: this.clapCountEl.nativeElement,
      isShowStart: false,
      isShowEnd: true,
      y: {0: -30},
      opacity: {0: 1},
      duration: this.tlDuration
    }).then({
      opacity: {1: 0},
      y: -80,
      delay: this.tlDuration / 2
    });

    const countTotalAnimation = new mojs.Html({
      el: this.clapCountTotalEl.nativeElement,
      isShowStart: false,
      isShowEnd: true,
      opacity: {0: 1},
      delay: 3 * (this.tlDuration) / 2,
      duration: this.tlDuration,
      y: {0: -3}
    });

    const scaleButton = new mojs.Html({
      el: this.clapEl.nativeElement,
      duration: this.tlDuration,
      scale: {1.3: 1},
      easing: mojs.easing.out
    });

    this.clapEl.nativeElement.style.transform = 'scale(1, 1)';

    this.animationTimeline = new mojs.Timeline();
    this.animationTimeline.add([
      triangleBurst,
      circleBurst,
      countAnimation,
      countTotalAnimation,
      scaleButton
    ]);
  } 

  repeatClapping() {
    if (this.currentClaps > 49) {
      alert('Limit 50 claps');
      return;
    }

    this.currentClaps++;
    this.claps++;
    this.clapsChange.emit(this.claps);

    this.animationTimeline.replay();
    this.clapIconChecked = true;
  }

  onClapMouseDown() {
    this.clapHold = setInterval(() => {
      this.repeatClapping();
    }, 400);
  }

  onClapMouseUp() {
    clearInterval(this.clapHold);
  }
}

As you can see there is no magic here. It's simple component with two-way binding that we can use anywhere as follows:

home.html

<clap [(claps)]="claps"></clap>

home.ts

export class HomePage {
  claps = generateRandomNumber(500, 10000);
}

function generateRandomNumber(min, max) {
  return Math.floor(Math.random() * (max - min + 1) + min);
}
