Parse a JSON Schema and generate TypedDict Python code.

from jsonschema_gentypes import SchemaParser, generate_types schema = { "type": "object", "properties": { "name": {"type": "string"}, "age": {"type": "integer"} }, "required": ["name", "age"] } parser = SchemaParser() # Parse the schema result = parser.parse(schema) # Generate TypedDict Python code code = generate_types(result) print(code)

Debug

Known issues

breakingIn v2.0.0, the API changed from argparse CLI to programmatic use; CLI was removed. Scripts relying on command-line invocation will break.

fix

Use the Python API (SchemaParser, generate_types) instead of CLI.

affects: >=2.0.0

breakingSchemaParser no longer accepts a file path directly; you must pass a dict or JSON string.

fix

Load your JSON file into a Python dict first, then pass to SchemaParser.parse().

affects: >=2.0.0

deprecatedThe option to generate dataclasses (instead of TypedDict) is deprecated and will be removed in v3.0.

fix

Switch to TypedDict generation if needed, or pin to <3.0.

affects: >=2.10.0

gotchaThe library does not validate the input JSON Schema; malformed schemas may produce cryptic errors.

fix

Ensure your schema is valid JSON Schema before passing to SchemaParser.

affects: all

gotchaGenerated TypedDict names are derived from schema title; if title is missing, names become generic ('GeneratedType').

fix

Always include a 'title' in your JSON Schema definitions.

affects: all
