OpenAPI Specification Visual Documentation

This is a prototype of a D3 rendering of the OpenAPI specification (fka Swagger Specification) to provide an easy to read visual documentation. It is developed by Arnaud Lauret, the API Handyman.

This is NOT a rendering of an API OpenAPI specification.

How to use it?

You can see a live demo on apihandyman.io

• Zoom in: Mouse scroll up
• Zoom out: Mouse scroll down
• Move: Mouse drag
• Clicking on a node expand or collapse it
• Moving mouse over a node shows its documentation

How does it work?

data contains a set of YAML files describing each object provided by the OpenAPI specification. The content of these files is based on the OpenAPI specification itself, some precisions have been added when needed.

Info Object:
  description: Provides metadata about the API. The metadata can be used by the clients if needed.
  allowExtension: true
  openapiType: true
  fields:
    - name: title
      type: string
      required: true
      description: The title of the application.
    - name: description
      type: string
      gfm: true
      description: A short description of the application.
    - name: termsOfService
      type: string
      description: The Terms of Service for the API.
    - name: contact
      type: Contact Object
      description: The contact information for the exposed API.
    - name: licence
      type: Licence Object
      description: The license information for the exposed API.
    - name: version
      type: string
      required: true
      description: Provides the version of the application API (not to be confused with the specification version).

All these files are concatened and converted in json in the data.json.

A tree is generated from the json file on runtime. All descriptions are converted from markdown to html.
