Utilizing Angular: Importing Scripts in index.html and Implementing Them in Components

Currently, I am attempting to integrate the Spotify SDK into an Angular application. While I have successfully imported the script from the CDN in index.html, I am encountering difficulties in utilizing it at the component level. It seems like there may be a fundamental step that I am overlooking, such as importing it correctly, as my attempts so far have been unsuccessful.

Although the information provided is limited, my primary query revolves around how to effectively utilize the imported script within a specific component.

Upon trying to employ the SDK at the component level, the following error message was displayed:

Property 'onSpotifyWebPlaybackSDKReady' does not exist on type 'Window & typeof globalThis'

In addition, I came across this source code, which I thought of using as an example to gain further insight into the integration. Despite my lack of understanding regarding its functioning, I noticed the inclusion of the following line in the project's package.json:

"@types/spotify-web-playback-sdk": "0.1.9",

You have the option to place this code in a file with the extension .d.ts anywhere within your project's src directory. The types were sourced from: https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/spotify-web-playback-sdk/index.d.ts, and then transformed into a module.

spotify.d.ts

export {};

declare global {
  interface Window {
    onSpotifyWebPlaybackSDKReady(): void;
    Spotify: typeof Spotify;
  }

  namespace Spotify {
    // Types and interfaces here
  }
}

To utilize it, you can create a global window function and subsequently attach the script programmatically:

export class AppComponent {
  ngOnInit() {
    window.onSpotifyWebPlaybackSDKReady = () => {
      console.log('spotify script loaded');
      const player = new Spotify.Player({
        name: 'nameHere',
        getOAuthToken: () => {
          'functionHere';
        },
      });
      player.connect().then((success) => console.log('Connected:', success));
    };
    const script = document.createElement('script');
    script.src = 'https://sdk.scdn.co/spotify-player.js';
    document.body.appendChild(script);
  }
}

Alternatively, you may install this package: https://www.npmjs.com/package/@types/spotify-web-playback-sdk

npm i @types/spotify-web-playback-sdk

Since it is not configured as a module, you will need to reference it manually like so:

///  <reference types="@types/spotify-web-playback-sdk"/>

import { Component } from '@angular/core';

@Component({ ... })
export class AppComponent { ... }

After some investigation, it appears that by following Konrad Linkowski's advice and defining a variable for the necessary objects, the problem can be resolved effectively. While there may be alternative approaches to tackle this issue, this method works flawlessly.

declare global {
  interface Window { onSpotifyWebPlaybackSDKReady: any; }
}
declare let Spotify: any;

window.onSpotifyWebPlaybackSDKReady = window.onSpotifyWebPlaybackSDKReady || {};
