Here's the minimal input:

Hi,
sorry for opening an issue which is not actually an issue :) I'm currently using script-loader to pack my javascript into the webpack file, and generate a sourcemap using webpack. Here's the config:

var config = {
    entry: {
      news: './news.js'
    },
    devtool: 'source-map',
    debug: true,
    output: {
      path: './bin',
      filename: '[name].js',
      sourceMapFilename: "[file].map.js"
    },
  };

This generates two files, news.js and news.js.map.js. The "packed" script in news.js are not minified, so I found your project which seems to do what i need, but after packing the scripts with "script-loader" and "uglify-loader", the sourcemap from webpack refers to the minified files, and i'm confused on how to use the sourcemap generated by uglify (

Here's an excerpt from my news.js file:

require("script!uglify!../../polling.js");
require("script!uglify!../../normalize.js");

So, my request is: how can I have the sourcemap of the un-uglified code? Do i need to start using the uglify one? How can i put all of it in a single file like webpack does?

Done, use uglify-loader webpack property to pass uglify-js options

I'd like to use uglify-loader to uglify files required with the script-loader.

My code looks as follows:

require('uglify-loader');
require('uglify!script!../lib/form2js/form2js');

When doing this I get the following error:

Module not found: Error: Cannot resolve module 'fs'
in ~/project/node_modules/uglify-loader/node_modules/uglify-js/tools
 @ ./~/uglify-loader/~/uglify-js/tools/node.js 2:9-22

When I use the UglifyJsPlugin the generated source maps contain the original (un-uglified) code. However, when I use this loader, the source maps contain the uglified code.

I really like this loader because it gives me better flexibility that the plugin, but I would still like to have useful source maps.

Users following the example in the README will get an error:

For loader options: webpack 2 no longer allows custom properties in configuration. Loaders should be updated to allow passing options via loader options in module.rules. Until loaders are updated one can use the LoaderOptionsPlugin to pass these options to the loader: plugins: [ new webpack.LoaderOptionsPlugin({ // test: /\.xxx$/, // may apply this only for some modules options: { uglify-loader: ... } }) ]

Webpack 2 uses a different method for module configuration. There are other differences as well. I don't know how many of them are impactful.

I'm willing to figure this one out and submit a pull request, but first I need to know if this loader is still actively maintained.

In our application, load our JS files by first parsing through babel-loader and then uglify-loader. When enabling source maps, it successfully maps the minified file to the unminified version, however, it does not preserve the source map generated by the babel-loader.

Removing the uglify-loader fixes this issue.

Am I doing something wrong? I can't get them to be combined such that the file maps to the original source.
