Recompile CSS

To recompile SCSS files, follow this setup:

Step #1 - Install tools

• NodeJS 12.x or higher
• Gulp - globally
  • npm install -g gulp-cli
• Yarn (optional)

Step #2 - Change the working directory to assets folder

$ cd app/static/assets

Step #3 - Install modules (this will create a classic node_modules directory)

$ npm install
// OR
$ yarn

Step #4 - Edit & Recompile SCSS files

$ gulp scss

The generated file is saved in static/assets/css directory.
