How to use this boilerplate

Content lives inside the src/ folder. If you do not want to change the configuration or are unsure about what you are doing, do not edit files outside the src/ folder.

Always run the following commands during the development stage and for production builds. Please note that it is expected that all projects built with this boilerplate are compiled using npm run build before they are published.

Commands

Command	Description
npm run dev	Runs a local web server for development and opens the browser to display it. Automatically compiles styles and scripts whenever a file in src/ is changed, and live reloads the browser. This is what must be run on the development stage.
npm run build	Compiles and minifies and optimizes the files in the assets folder. The generated compiled and optimized files are located in the dist/ folder. This is what must be run before publishing the project. This is also the build command to be run by external deployment services such as Netlify. The publishable files are then located in the dist/ folder.
npm run clean	Deletes the current /dist folder and cache folders.
npm run test	Displays a success message if everything is working as expected.
