This lesson provides a comprehensive guide to implementing assets in blocks through block.json configuration. You’ll learn the five key asset types: editorScript (required JavaScript), editorStyle (editor-only CSS), script (shared JavaScript), style (shared CSS), and viewScript (frontend JavaScript).
The lesson emphasizes running development builds when modifying assets and explains that WordPress only needs file paths while WP Scripts requires specific naming conventions. Key concepts include understanding that WordPress loads the built block.json (not source), index.js serves as the main entry point for bundling, and the confusing but necessary transformation where style.scss becomes style-index.css and editor.scss becomes index.css.
The lesson covers both the technical requirements and practical workflow for managing all block assets effectively.
