default css class loader for webpack

What

This loader adds toString() to a style object that load via css-loader.

By default it will return .root.

style.css

.root {
  border: 1px solid #ddd;
}

Before

const style = require('./style.css');

console.log(style);      // [object Object]
console.log(style.root); // root___1J7bD

After

const style = require('./style.css');

console.log(style);      // root___1J7bD
console.log(style.root); // root___1J7bD

Why

BEM style like CSS naming conventions with CSS-Modules made easy.

import React from 'react';
const Button = require('./button.scss');

const PrimaryButton = (
  <button className={`${Button} ${Button._primary}`}>Hi</button>
)

import React from 'react';
const searchForm = require('./searchForm.scss');

const SearchForm = (
  <form className={`${searchForm}`}>
    <input className={`${searchForm.input}`}>
    <button className={`${searchForm.button} ${searchForm.button_disabled}`}>
      Search
    </button>
  </form>
)
