ReactJS - including other scss files in main.scss

Question

In my reactJS application - I am including all .scss files in one main.scss file - under styles folder in src folder. I have the following webpack configuration. tried including main.scss file directly in my main component - getting error at '@import' where I import other scss files. if i include separate scss file styles are fine - but how to get this working with one main.scss file and how to include it?

error: Unexpected token, expected ( (1:8)

You should import your .scss file via javascript in your top level React component.

import './styles/main.scss';

Webpack will then include it in your bundle.

For production you will want to use the Extract Text Plugin for webpack which will export a separate css file from the import statement.
