Mermaid diagrams often fail at the last moment due to syntax errors or unsupported constructs, which wastes time during documentation and review cycles.
Use case: Validate a diagram.mmd before including it in a README or PR description so reviewers don’t hit broken diagrams in their rendered view.
Run the command to validate your file: ./tools/validate.sh diagram.mmd output.svg

You can validate Mermaid diagram syntax by running the official Mermaid CLI against a standalone .mmd file. The tool parses and renders the diagram, failing on non-zero exit codes to enforce correctness before you paste it into Markdown.
Yes, you can generate an optional SVG output file when validating Mermaid syntax. By providing an output path like output.svg to the validation script, the Mermaid CLI renders the diagram to SVG.
Yes, you need a Node-based execution environment because the validation runs via npx mermaid-cli. This dependency executes the official CLI to parse and render your .mmd files.
Mermaid diagrams often fail to render due to syntax errors or unsupported constructs. Validating the .mmd file with the official Mermaid CLI before committing catches these errors during review cycles.
The best way to spot obvious layout issues without a browser is to generate a best-effort ASCII preview. This feature runs alongside the Mermaid CLI validation to quickly confirm diagram structure.
Yes, this validation fits documentation and product workflows where diagrams are authored as .mmd files. It confirms syntax correctness before diagrams are pasted into PR descriptions or README files.
