# How to include direct .js reference in Ionic application

I really want to try out the library iscroll in my Capacitor hosted Ionic application, we I want the momentum scrolling when built for desktop.

At this stage, I just want to see how it performs, but as explained here, I just cannot get it to even be included in an Ionic/Angular project.

So I thought I’d try and just manually include it. So I added it my folder eg `D:\dev\capacitor\electron2\src\lib\iscroll.js`, and added

`<script src='build/iscroll.js'></script>`

into `D:\dev\capacitor\electron2\src\index.html`, and finally added this to the tsconfig.json file…
ie

``````"include": [
"src/**/*.ts",
However this file is neither copied into the build folder, nor is it included in the bundle. If I look in `D:\dev\capacitor\electron2\www\build\main.js` none of the code is in there.
