I\'m using blueimp-file-upload in my website, and I\'m using webpack to organize my js code.
I installed blueimp-file-upload and jquery.ui.widget from NPM
actually you can solve this by changing your webpack config, just add the path to resolve (for example I am using bower)
resolve: { extensions: [ '', '.js', '.jsx' ], modulesDirectories: [ 'node_modules', 'bower_components', 'bower_components/blueimp-file-upload/js/vendor' ] }
