It causes problems for our Webpack production build. Specifically after UglifyJsPlugin name mangling angular-file-upload.min.js script is broken. It's all works as expected with non-minified angular-file-upload.js file.
I think it's considered a best practice to set main entry of package.json to non-minified version of your code. So client bundler (webpack or anything else) could take care of concatenation and minification.
