SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It solves the problem of creating and updating Mermaid diagrams without a GUI by letting you manage diagram content through a command-line workflow and render/sharing endpoints for quick review.

Core Features & Use Cases

  • Stateful Mermaid project files: Create, open, save, and inspect diagram projects so diagram edits are reproducible and easy to automate.
  • Source editing and session control: Replace Mermaid source text, view the current diagram code, and use undo/redo to iterate safely.
  • Render and share via Mermaid Live-compatible flows: Render to image formats and generate Live Editor URLs for collaboration.
  • Use Case: An AI agent generates a sequence diagram from structured requirements, saves it as a project file, renders it to PNG for a report, and returns a shareable URL for stakeholder feedback.

Quick Start

Create a new Mermaid project from the command line and render it to an output image for immediate viewing.

FAQPage Schema
How do I generate Mermaid sequence diagrams from the command line?

You can generate Mermaid sequence diagrams by using a CLI to create stateful JSON project files, edit source text, and render outputs without needing a graphical interface. The CLI supports flowcharts and sequence diagrams for automated project workflows.

Can I render Mermaid diagrams and get a shareable link without a GUI?

Yes, you can render Mermaid diagrams to image formats via the mermaid.ink renderer and generate shareable Live Editor URLs directly from the command line. This allows quick collaboration and stakeholder review without opening a GUI.

How do I iterate on Mermaid diagram source code in an automated workflow?

You can iterate on Mermaid diagram source code by replacing text, viewing current code, and using undo/redo commands within a CLI session. Edits are saved as persistent JSON project files, making reproducible diagram generation and iteration easy to automate.

Do I need any external dependencies to use a CLI for Mermaid diagram generation?

No external dependencies are required to use this CLI for Mermaid diagram generation. You need a command-line interface capable of maintaining session state to produce human-readable and machine-readable JSON output and render diagrams via mermaid.ink URLs.

What is the best way to automate flowchart creation for project-based workflows?

Automating flowchart creation is best done by managing diagram content through a command-line workflow that saves edits to persistent JSON project files. This approach enables AI agents to generate, edit, and render reproducible diagrams for automated project workflows.
