This starter kit is for developers who want to build modern, JavaScript-focused extensions for a widely-used content management system. It provides a foundation that includes a local development environment, a build system, and educational steps to understand the underlying tooling.

Local Environment Setup: Includes a Docker configuration to quickly launch a consistent local development server and database, allowing for immediate testing.

Build System: Uses Parcel as a zero-configuration bundler to compile and minify JavaScript files for production, handling tasks like code splitting and asset management.

Modern JavaScript Support: Pre-configured with Babel to support JSX and the latest ECMAScript features, enabling the use of component-based UI patterns common in modern web development.

Educational Structure: The project is built step-by-step through a series of commits, each explaining a core concept like script enqueuing, bundling, and block registration, making it a practical learning resource.

Packaging Script: Includes a command to generate a production-ready ZIP file containing only the necessary PHP and built JavaScript assets, ready for distribution or installation.
