penny
a zero-config on-the-fly-compiling dev server
...which also builds and is configurable

npm install -g @lunelson/penny

Penny is not another bundler. It is an on-request in-memory-compiling live-reloading server for development, and a static-site builder for production. It avoids the pain of build-tool configuration, and the wasted time of full-site rebuilds.

• Pug.js, Libsass (via node-sass) and Babel/Webpack as view-engines
• Advanced helper functions incl. data-loading in templates and stylesheets
• Sourcemaps, file-watching and live-reloading in development; minification and purging in production
