Key features
- Supports mermaid, mermaidjs, and mmd fenced code blocks
- Works with the DSH/Shiki plain fallback, where code elements may not have a language class
- Bundles the exact Mermaid 11.17.0 release and requires no runtime CDN
- Loads the bundled Mermaid runtime from DSH only after the first Mermaid block is detected
- Renders multiple diagrams through a serial queue and yields between renders to keep the page responsive
Requirements
- Last verified with @deepseek-ai/dsh 0.1.2-rc.1 on 2026-09-05 using Node.js 22.23.2.
- DSH is currently a developer preview and may introduce compatibility-breaking changes
