I'm trying to use uppy with webpacker on rails, I am having trouble getting uppy to work:

//  app/javascripts/src/javascript/my_scripts.js    

const Uppy = require('@uppy/core')

const DragDrop = require('@uppy/drag-drop')

const ProgressBar = require('@uppy/progress-bar')



const uppyOne = new Uppy({debug: true, autoProceed: true})

uppyOne.use(DragDrop, { target: '.UppyDragDrop-One' })

This is the console error I'm receiving:

[Uppy] [23:29:46] Not installing DragDrop

Plugin.js:165 Uncaught Error: Invalid target option given to DragDrop. Please make sure that the element 

      exists on the page, or that the plugin you are targeting has been installed. Check that the <script> tag initializing Uppy 

      comes at the bottom of the page, before the closing </body> tag (see https://github.com/transloadit/uppy/issues/1042).

I found out the problem is because in rails you usually link to all JS files up in the head of the layout file but the element with class '.UppyDragDrop' has yet to be rendered.

To resolve, you need to separately link to the javascript via javascript_pack_tag after the element with the DragDrog element is presented.
