Generate static HTML documentation from JSON schemas

Project description

JSON Schema for Humans

Quickly generate a beautiful HTML static page documenting a JSON schema



pip install json-schema-for-humans


generate-schema-doc [OPTIONS] SCHEMA_FILE [RESULT_FILE]

SCHEMA_FILE must be a valid JSON Schema

A CSS file will be copied in the same directory as RESULT_FILE

The default value for RESULT_FILE is schema_doc.html



On by default

Minify the output HTML document


Off by default

Mark a property as deprecated (with a big red badge) if the description contains the string [Deprecated


Off by default

Extract the default value of a property from the description like this: [Default `the_default_value`]

The default value from the "default" attribute will be used in priority

What's supported

See the excellent Understanding JSON Schema to understand what are those checks

The following are supported:

  • Types
  • Regular expressions
  • Numeric types multiples and range
  • Constant and enumerated values
  • Required properties
  • Default values
  • Array minItems, maxItems, uniqueItems, items (schema that must apply to all of the array items), and contains
  • Combining schema with oneOf, allOf, anyOf, and not

These are not supported at the moment (PRs welcome!):

  • String length and format
  • Property names, size, and pattern
  • Array items at specific index (for example, first item must be a string and second must be an integer)
  • Property dependencies
  • Examples
  • Media
  • Conditional subschemas

References from inside a schema are supported (for example { $ref: "#/definitions/something" } will be replaced by the content of schema["definitions"]["something"])

References to schemas in other files are not supported for now.



Just run tox


Generating doc

The documentation is generated using jekyll and hosted on GitHub Pages

  • Change your current working directory to docs
  • Run python This will get all examples from tests/cases, render the resulting HTML and include it in the appropriate folders in the jekyll site.
  • If you have added an example, add the file name (without .json), the display name and description in _data/examples.yaml
