Tips for injecting scripts into the head tag after an Angular component has been loaded

Currently, I am facing an issue with a script tag containing a Skype web control CDN. The script has been placed in the head section of my index.html file, but it is being called before the component that needs it has finished loading. Does anyone have any suggestions on how I can properly reference this script within my component?

Answer №1

After some investigation, I've come up with a solution. In order to achieve the desired outcome, you must dynamically generate a script tag and then attach it to the head of your document:

export class Widget {

//...

injectScript() {
  let element = document.createElement('script'); // create the script tag dynamically
  element.src = ''; // specify the source (insert URL within quotes)
  element.type = 'text/javascript'; // define the type of script
  element.async = true; // enable asynchronous execution
  element.charset = 'utf-8';
  // append the script tag to the document's head
  document.getElementsByTagName('head')[0].appendChild(element); 
}

initialize{
  injectScript();
}

Answer №2

The script tag is being called before the necessary component has finished loading. Are there any suggestions on how I can properly reference this script within my component?

Most script tags typically export a global variable such as React, $, or _. It would be helpful to refer to the documentation of the library and utilize the global variable that they export.
