@mermaid-js/mermaid-cli is a command-line interface tool for Mermaid, a popular diagramming and charting tool that uses a Markdown-like syntax. This CLI allows users to generate diagrams from Mermaid syntax files directly from the command line. It streamlines the process of converting Mermaid code into image formats like SVG or PNG, facilitating integration into automated workflows, documentation pipelines, and build processes. Ideal for developers seeking efficient diagram generation without the dependency on a browser environment.
