Edit
Let’s look at the big picture and the architectural and UX principles of the block editor and the Gutenberg repository.
Editor
- Key concepts.
- Data format and data flow.
- Entities and undo/redo.
- Site editing templates.
- Styles in the editor.
- Performance.
Gutenberg Repository
- Modularity and WordPress Packages.
- Understand the repository folder structure.
- Outdated! Why is Puppeteer the tool of choice for end-to-end tests?.
