$ npm install
$ npm start
After installing dependencies from NPM, npm install additionally runs Bundler to install Ruby gems required by Jekyll.
npm start runs bundle exec jekyll start --livereload, and spins a demo page up at http://localhost:4000. Changes will automatically refresh in the browser.
The demo styles in /assets/stylesheets/demo and placeholder markup in index.html can be erased once the project is running locally.
The main SCSS manifest is assets/stylesheets/application.scss. USWDS theme files are imported from assets/uswds-theme, and USWDS is imported from node_modules/uswds. In this implementation, all of USWDS is imported by default. For a custom configuration, comment/uncomment the desired USWDS components in the manifest.
Project CSS is located in assets/stylesheets/. Create directories and .scss to suit project needs and @import them in application.scss. USWDS tokens/variables/etc will be accessible across custom stylesheets.
JavaScript is imported and concatenated into assets/js/application.js. Importants are handled with Jekyll’s include_relative method.
Place scripts in assets/js and link to them in assets/javascripts/application.js.
Edit the USWDS version number in package.json, then ...
$ npm install
$ gulp update
npm install will update USWDS files (and any other dependencies, too) in node_modules.
gulp update copies fonts, images, JS, and builds SASS. It skips the copy-uswds-setup portion of gulp init, which would overwrite existing theme settings in assets/uswds-theme. Check that USWDS updates haven't altered the setup of theme files. Double check that updates haven't changed paths referenced in assets/stylesheets/application.scss.
To reset USWDS and USWDS theme settings, run ...
$ gulp init
This will re-run the initial Gulp setup as per gulpfile.js. This copies USWDS files to assets/, including assets/uswds-theme. Any customization to USWDS theme settings will be overwritten with defaults.
After running, additional configuration may be needed to get uswds-theme working. See the USWDS settings documentation for help.
