Need

As a developer
I want to use css preprocessors
So that I'll increase my productivity and DX[Developer Experience]

Solution

• add less-loader as dev dependencies
• in webpack.config.development.js

{
  test: /\.less$/,
  loader: ['style-loader!css-loader!less-loader']
}

• in webpack.config.production.js

{ 
  test: /\.less$/,
  loader: ExtractTextPlugin.extract('style-loader','css-loader!less-loader')
}

Thanks for high quality PR here 👍 , but I doubt we should support less in this boilerplate.

See also #50, now I want to keep webpack config just simple:

I ever use sass, scss, less, stylus before and now postcss. We should not support all of those in one boilerplate and should let user make a decision themselves.

@chentsulin fair enough 👍

What do you think about ExtractTextPlugin initialization, this commit, can we merge it, without less of course, or it's out of scope?

Thanks for high quality PR here 👍

It's not a problem, since this repo is a bless 🍰

Sure, maybe open a new PR or rebase to modify on that commit, after that i will merge or cherry-pick it.
