Next.js

This app shows how you can use extracted stylesheets for maximum performance in production.

Features:

• Hot reloading in development without CSS-in-JS
• 100% Page Speed score and 100% YSlow score (if put behind CDN)
• Critical stylesheets injected per-device (phone, tablet, desktop)
• SCSS and PostCSS with autoprefixing for styling
• Content hashes for all resources for best integration with CDNs
• Properly setup Cache headers for resources
• Auto-bundling images referenced as url() in stylesheets
• Auto-bundling of imported and required images
• Inlining small images as Data URI (in both stylesheets and SSR page)
• Properly handling multiple pages and routing between them
• Ability to fallback to dynamic pages
• Importing single icons from Font Awesome
• GZip compression of served pages

How to use

Download the example or clone the repo:

curl https://codeload.github.com/zeit/next.js/tar.gz/master | tar -xz --strip=2 next.js-master/examples/with-extracted-stylesheet
cd with-extracted-stylesheet

To get this example running you just need to

npm install
npm run dev

Visit http://localhost:3000 and try to modify styles/index.scss changing color. Your changes should be picked up instantly.

Deploying as static website

You should get complete webpage in out directory after running npm run build.

It is recommended to use node bin/start as a server though, to get dynamic content as fallback.
