About this plugin
In AI-driven workflows, complex system architectures, business processes, or dependency graphs are frequently delivered as raw text code blocks, making them tedious to parse and visualize. dsh-mermaid bridges this gap by seamlessly integrating into the DSH Web interface, automatically detecting and transforming scattered Mermaid syntax into crisp, interactive diagrams right within your chat sessions.
Built for reliability and safety, the plugin offers a highly tunable rendering engine with automatic theme syncing, plus built-in performance safeguards like text and edge limits to prevent browser overload. It enforces a strict security sandbox using internal DOMPurify sanitization and lazy click handling, ensuring zero cross-site scripting risks. Optimized for modern streaming AI outputs, it waits until content stabilizes before rendering and provides graceful fallbacks—displaying the original code alongside clear error summaries and console logs whenever parsing fails.
Designed specifically for developers, system architects, technical writers, and AI power users who rely on DSH Web for rapid ideation, architecture planning, or documentation generation. Say goodbye to manually copying syntax to external tools; let this plugin turn your conversational prompts into polished visual insights instantly, keeping your focus strictly on design and decision-making.
