Hi, I really enjoyed your course and I like your set up. Is there any updated version that wouldn't rely on the deprecated extract-text-webpack-plugin and would be using the latest stable @babel/core? I've tried to reproduce it with mini-css-extract-plugin, but I ran into a dead-end that is beyond my current knowledge. I get the CSS compiled. I get the editor.blocks.js compiled, but the blocks are not there (their script is not getting executed), despite the fact that I can see the file itself is loaded by Wordpress.
