How can I import external JavaScript file?

Question

I need to import a JS file that is hosted on another server and is not part of my application's assets.

How can I import it from within the component?

Answer 1

I ended up setting up environmental JavaScriptSupport and calling importJavaScriptLibrary from within setupRender():

@Environmental
private JavaScriptSupport javaScriptSupport;

public void setupRender() {
    this.javaScriptSupport.importJavaScriptLibrary("URL-to-JS-file");
}
