resx-webpack-loader

Thanks to Luke Howard, @binaryluke for his package jsonfromresx.

The important stuff:

module.exports = {
    ...
    resolveLoader: {
      alias: {
        'resx-loader': path.join(__dirname, './node_modules/resx-loader')
      },
      modulesDirectories: [
        path.resolve(__dirname, './node_modules/')
      ]
    },
    module: {
        loaders: [
            {
              test: [/\.resx$/], loader: 'resx-loader'
            }
        ]
    }
    ...
};

The entire webpack config object of an example use case. Example project can be found at https://github.com/slimeygecko/dojo-webpack-example
