Source code for my course: The Complete Guide to Building Premium WordPress Themes

• Download or clone the repository in the WordPress themes directory.
• Activate the theme from wp-admin.
• Open the CMD/Terminal and change to the theme's directory (/wp-content/themes/firstheme)
• Run npm install
• Go to gulpfile.babel.js and find this code:

  export const serve = done => {
  server.init({
      proxy: "http://localhost:8888/myfirsttheme"
  });
  done();
  };
  

  And change the proxy URL to the URL of your WordPress installation on your machine. The port will vary depending on the software you are using (WAMP,MAMP,XAMPP, etc..)
• Run npm run start, this will open a browsersync url where your browser will refresh every time you change some code in your theme.
• npm run start is useful for development. For production you can run npm run build to generate minified assets for production. (You can see generated assets in the dist folder)
