This is an awesome list of resources, Jeff! Thanks for that. 💯

I'd like to mention (shameless plug) one of my projects:

— Gutenberg Boilerplate: Easy to understand and extensively inline documented starter WordPress plugin for the new Gutenberg editor.

— WPTavern's article about it: Gutenberg Boilerplate Demonstrates How to Build Custom Blocks →

About 500 developers have used this project, the intent was to write a few blocks and then extensively inline document them. With ~400 stargazers this is one of my most popular free and open source software repo over there at GitHub.

🤔 P.S. It has also helped me understand what developers are really looking for when they start building Gutenberg Blocks. So, I am releasing a sister project next week. I hope it's worth it.

Peace! ✌️
