Implementing dynamic loading of script files in app.component.ts using Angular

I am currently working with Angular2 and TypeScript.

Within my app.component.ts file, I need to dynamically load script files based on the current navigator language. To achieve this, I have added the following function in my home.component.ts:

export class HomeComponent {
constructor() {
    this.loadDynamicallyScript();
  } 
public loadDynamicallyScript() {
    let node = document.createElement('script');
    node.src = "../node_modules/xxxxxxxxxx/xx." +   navigator.language"+".min.js";
    node.type = 'text/javascript';
    document.getElementsByTagName('head')[0].appendChild(node);
 }

However, this approach is not functioning as expected. I still need to successfully load the files on demand according to the current navigator language. Does anyone have any suggestions or solutions for this issue? Thank you for any assistance provided.

Answer №1

To include the JavaScript file located in 'assets/js/index.js', you can use the import statement as shown.

Before importing the scripts, make sure to change your functions to exports so they can be accessed outside the script.

Lastly, in the ngOnInit function, remember to call the necessary functions that should be executed when the page loads.

Answer №2

To ensure the script is loaded properly, it must be readily available for loading. Simply manually copying script files to the public folder will not suffice; attempting to add a script in this manner using document.createElement would be an incorrect approach.

Webpack is already equipped to handle dynamic imports. However, some additional steps are necessary to guarantee that the lazily loaded script is properly bundled by Webpack. It's important that the import name is conducive to static analysis, and further options can be specified through comments.
