Having trouble integrating ColorThief with Angular, encountering issues with missing library methods?

I am attempting to integrate the Library ColorThief () into an Angular 12 project, but unfortunately, I have been unable to make it work. I started by running $ npm i --save colorthief and then in my desired component .ts file:

const ColorThief = require('colorthief');
.

The compilation is successful, however, some of the methods are not being recognized when triggered in the browser.

I also attempted adding the script tag to my index.html file, without any luck.

This is a snippet from my Component TS file:

import { Color } from '../shared/model/color';
const ColorThief = require('colorthief');
//import ColorThief from 'angular-colorthief';

@Component({
  selector: 'app-home',
  templateUrl: './home.component.html',
  styleUrls: ['./home.component.css']
})
export class HomeComponent implements OnInit, AfterViewInit {
...
autoGeneratePalette(numColors:number) {
    this.userPalette = [];
      this.paletteCounter = 0;
    //var ColorThief:any = new ColorThief();
      ColorThief.getPalette(this.imgToUse, numColors)
      .then((palette: any) => {
      for(var i = 0; i < palette.length; i++) {
        var color = new Color(0,0,0,0);
        color.red = palette[i][0];
        color.green = palette[i][1];
        color.blue = palette[i][2];
        color.index = i;
        this.userPalette.push(color);
      }
    })
    .catch((err: any) => {console.log(err)});
    }
}

Does anyone have any insights on what could be going wrong? Or has anyone successfully implemented ColorThief in Angular before?

Answer №1

const fetchColorPalette = () => {
    import ColorThief from 'colorthief';

    const img = document.querySelector('img');

    const colorThief = new ColorThief();

    if (img.complete) {
        this.primaryColor = colorThief.getColor(img);
    } else {
        img.addEventListener('load', () => {
            this.primaryColor = colorThief.getColor(img);
        });
    }
}
