npm start
This starts the webpack dev server at http://localhost:8080.
npm run build
npm run deploy
The static files are deployed to github at https://dounan.github.io/dounan-mubla/.
npm run stats[-dev]
The command above will output a file build-stats[-dev].json that can be analyzed with a tool such as http://webpack.github.io/analyse/.
Each CSS file should correspond to exactly one component. Because of this, it makes more sense to keep the CSS file right next to the component file. This is why the CSS files are also placed in the components directory with the same name as the .jsx file.
Not every component needs to have a CSS file.
