Introduction

Koenig is the editor developed by and used within the Ghost content management system. Koenig is built on the Lexical editor framework and extends Lexical JSON with additional card types for Ghost-specific content such as image galleries, embedded content, and email CTAs.

Stencila supports conversion to/from Koenig JSON to enable publishing Stencila documents to Ghost.

Usage

Use the .koenig file extension, or the --to koenig or --from koenig options, when converting to/from Koenig JSON e.g.

stencila convert doc.smd doc.koenig

Implementation

Stencila supports bi-directional conversion between Stencila documents and Koenig JSON, implemented in the Rust crate codec-lexical. The codec builds on the Lexical JSON codec with additional transformer functions for Koenig-specific card types.

Limitations

Stencila node types that have no Lexical or Koenig card representation are lost during export.

Ghost-specific card types (e.g. product cards, signup forms, email content cards) may not fully map to Stencila nodes during import.

Koenig's content model is simpler than Stencila's; complex document structures are flattened.
