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-react-toolbox
cd with-react-toolboxInstall it and run:
yarn
yarn devNotice that yarn toolbox (or npm run toolbox) should be rerun every time the "reactToolbox" configuration in package.json is changed, in order to update static/theme.js and static/theme.css. The "reactToolbox" configuration includes styling, and the list of react-toolbox components to include.
This is a simple example of getting react-toolbox up and running, using react-toolbox-themr.
For actual use, you probably also want to add Roboto Font, and Material Design Icons. See http://react-toolbox.com/#/install
