Block Format Bridge

This plugin serves as a central hub for converting content between three primary formats: HTML, serialized block markup, and Markdown. It is designed for developers and site builders who need to work with content in different formats, whether for importing, exporting, or processing within a content management system. The tool composes existing, specialized libraries behind a single, consistent interface, ensuring reliable conversions without reinventing core parsing logic.

Format Conversion: The core function converts content bidirectionally between HTML, block markup, and Markdown. All cross-format conversions route through a block-array pivot, ensuring consistency.

Normalization: Beyond conversion, it can validate and normalize content that is already declared to be in a specific format. This helps clean imported or user-generated content before storage.

Extensible Adapter System: New content formats can be supported by registering a new adapter. The core system does not need modification, keeping it lean and focused on orchestration.

REST API Integration: The plugin extends the REST API for supported post types, allowing content to be requested and delivered in a specified format via a simple query parameter.

Developer-Focused API: It provides clear PHP functions and WP-CLI commands for programmatic conversion, making it suitable for use in themes, custom plugins, and build processes.
