Step: Markdown to PDF

• Key: markdown-to-pdf
• Category: Utilities
• Description: Convert Markdown content from the flow context into a PDF and return it as base64.

Inputs

• markdownKey (select, required): Context key containing Markdown content. If the value is an object, the runtime uses markdown, then content, then a JSON string representation.
• fileName (text, optional): Suggested file name. Defaults to document.pdf; .pdf is appended when missing.
• title (text, optional): PDF document title metadata.

Outputs

• base64 (text): Generated PDF file content as a base64 string.
• mimeType (text): MIME type of the generated file.
• fileName (text): Suggested PDF file name.
• size (number): Generated file size in bytes.

Notes

• The runtime renders GitHub-flavored Markdown, sanitizes the generated HTML, and prints it to A4 PDF.
• External network requests from the generated document are blocked during rendering.
• Use save-file after this step when you need a downloadable file link.

Example Use Case

1. Use ask-to-llm or agent to generate Markdown and store it as report.markdown.
2. Use markdown-to-pdf with markdownKey = "report.markdown" and fileName = "weekly-report.pdf".
3. Return the base64 directly or save it with a file step.
