@svengroup/openapi-to-pdf

Create PDF API reference documentation from OpenAPI 3.0.x specification files.

This tool works by first generating markdown content which is then converted into PDF.

You may view the sample PDF output here: /samples/api-reference.pdf.

It shows a PDF version of /samples/openapi.yaml when the configuration at /samples/config.json is used.

Inclusions

This tool includes the following:

• YAML and JSON OpenAPI 3.0.x support
• Fully configurable:
  • Header & footer
  • Cover page
  • Table of contents
  • Headings and texts
  • Custom Sections
  • PDF settings (thanks to md-to-pdf)
• Programmatic usage with markdown output
• TypeScript support

Acknowledgements

This tool was built upon the generous open source work of other developers, big thanks to:

• @simonhaenisch for md-to-pdf which powers markdown to PDF conversion for this tool.
• @seriousme for @seriousme/openapi-schema-validator which this tool uses to validate and parse OpenAPI files. The OpenAPIV3.Document interface is also directly from this package.
• TJ Holowaychuk for commander.js which made making the cli a lot easier.
• All the other developers who worked on the packages we use for this tool!
