Leveraging Global Functions with Angular 5

I am faced with the challenge of integrating video.js into my IonicFramework application built using Angular. I attempted to install it via npm, but encountered issues with TypeScript recognizing any importable module, and was unable to find clear documentation on incorporating it into TS/ES6 applications.

To work around this, I tried treating video.js as a regular JavaScript library. I added the video.js script to my index.html file:

<script src="assets/js/video_v6_6_3.js"></script>

Upon inspection, the script declares a function called videojs in the global scope (a practice that I find less than ideal).

In my application, I attempted to call this function within the ngAfterViewInit method like so: videojs(this.videoId);. However, during runtime, TypeScript threw an exception:

Typescript Error
Cannot find name 'videojs'.

Is there a way to package such libraries for seamless integration with Angular's importing system? Or perhaps a method to prevent TypeScript from throwing errors when using these kinds of functions? I have searched extensively but found no resources addressing this specific scenario.

Answer №1

If you want to silence typescript's complaints, one quick fix is to simply declare it as any:

declare const videojs: any;

Alternatively, you could attempt importing it in the following manner (not validated):

import * as videojs from 'videojs';
