JS tools to Typescript

I am migrating my Ionic1 project to Ionic2 these days. Fun! One hurdle right now is to migrate a long list of tool functions written in JS such as CmToFeet / InchesToCM / FarenheitToCelsius to the Ionic2 project. I do not know how to properly include these files in the project and make sure they will be considered for the build process. Can I just include them in the index.html and they automatically will be available? Do I need to do more? Any tips?

One of the easiest ways to do that would be to treat it just as another asset. To do so, you can create a folder in src/assets/scripts, put those js files there and then add the script tag in your index.html file like this:

<script src="assets/scripts/jsFileName.js"></script>

If you used to call those functions by doing something like CmToFeet.methodName(), now you will need to declare CmToFeet variable to prevent typescript errors

import {... } from '...';

declare var CmToFeet: any; // <- Like this

@Component({
    selector:'my-page',
    templateUrl: 'my-page.html',
})
export class MyPage {

  // ...

}

Please notice that by doing things like this, the autocomplete features won't work since it's declared as of type any.
