I know that ArcGIS Web AppBuilder Desktop is built using Node.js
Is there any way we can add the third party node.js modules in Web AppBuilder Desktop using the npm command and then access these modules in the custom widget?
For example, I would like to use the npm module: https://www.npmjs.com/package/xlsx In a custom widget
Where do I write the command to download the module?
After downloading the module how do I access it in the custom widget?
