Vaadin 10: SASS Integration and CSS-Refresh Development Workflow
# start the app (execute main() in Vaadin10SassCssrefreshApplication) mvn sass:watch # open http://localhost:8080/ # change sass # profit (= css will be updated in the browser without a page reload)
If you are not using
sass:watch, mind to execute at least
mvn sass:update-stylesheets once up front before starting the app. Otherwise there will be no CSS at all.
