There are a few different operations available for this style guide.
gulp gulp watch
These commands allow you to work on the styleguide by enabling the Fractal server and watching for changes in SCSS and JS files. Validation of these files is also done when editing and saving them.
This command validates all SCSS and JS files and reports back when syntax errors have been found.
gulp compile gulp compile:dev
These commands depending on the one you use execute a certain amount of tasks:
compile only!) Minification of the compiled CSS code.
compile only!) Minification of the JS code
This command combines the gulp validate and gulp compile commands. It is used to build a final version of the styleguide, ready to be published to NPM.
