从Webpack 1迁移到Webpack 2

Question

I'm currently migrating Webpack1 to the second version. As I saw here ,

"Webpack is now using Postcss and cssnano in CSS-loader."

• That means that I don't need to install postcss-loader?
• In my old Webpack.config.js file I have this:

 webpackConfig.postcss = [ cssnano({ autoprefixer : { add : true, remove : true, browsers : ['last 5 versions'] }, discardComments : { removeAll : true }, discardUnused : false, mergeIdents : false, reduceIdents : false, safe : true, sourcemap : true }) ]; 

How do I use those options in the new Webpack 2?

Answer 1

You could pass in the 'mimimize' option to css-loader

...
    loader: 'css-loader',
    options: {
        minimize: true,
...
