Output Format API

The Output Format API module provides a robust framework for content negotiation and format transformation, enabling seamless conversion of Drupal entity output into multiple formats (e.g., Markdown, PDF). This module is ideal for developers and site builders aiming to deliver diverse content formats to their audience with minimal setup.

Features

The Output Format API offers:

• Standards-Based Format Negotiation: Supports HTTP content negotiation via the Accept header (e.g., Accept: text/plain) and complies with IANA media type standards.
• Flexible Content Transformation: Converts HTML or other entity-rendered outputs into formats like Markdown or PDF.
• Extensible Framework: Allows developers to define custom converters for new formats. Extend the module to support additional formats by implementing the OutputFormatConverterBase plugin class.
• Entity-Specific Formatting: Generate format-specific representations for individual entities or bundles, enabling granular control.

Use cases include:

• Providing alternative format downloads for articles, reports, or documentation.
• Simplifying workflows for static site generation.
