Python package to generate an httpx- and pydantic-based async (or sync) client off an OpenAPI spec >= 3.0.

flowchart LR
    generator["python-client-generator"]
    app["REST API app"]
    package["app HTTP client"]

    app -- "OpenAPI json" --> generator
    generator -- "generates" --> package

⚠️ Currently does not support OpenAPI 2.0: PR for < 3.0 support are welcome

python -m python_client_generator --open-api openapi.json --package-name foo_bar --project-name foo-bar --outdir clients

This will produce a Python package with the following structure:

clients
├── foo_bar
│   ├── __init__.py
│   ├── apis.py
│   ├── base_client.py
│   └── models.py
└── pyproject.toml

When calling one of the generated update functions that uses an HTTP PATCH method, you'll probably want to pass the additional argument body_serializer_args={"exclude_unset": True}. This will ensure that only the fields that are set in the update object are sent to the API. Example:

await api_client.update_contact_v1_contacts__contact_id__patch(
                body=patch_body,
                contact_id=contact.id,
                tenant=tenant,
                body_serializer_args={"exclude_unset": True}
)
