Usage

From command line

spec2sdk --input path/to/api.yml --output-dir path/to/output-dir/

From the code

from pathlib import Path
from spec2sdk.main import generate

generate(url=Path("path/to/api.yml").absolute().as_uri(), output_dir=Path("path/to/output-dir/"))

Open API specification requirements

Operation ID

operationId must be specified for each endpoint to generate meaningful method names. It must be unique among all operations described in the API.

Input

paths:
  /health:
    get:
      operationId: healthCheck
      responses:
        '200':
          description: Successful response

Output

class APIClient:
    def health_check(self) -> None:
        ...

Inline schemas

Inline schemas should be annotated with the schema name in the x-schema-name field that doesn't overlap with the existing schema names in the specification.

Input

paths:
  /me:
    get:
      operationId: getMe
      responses:
        '200':
          description: Successful response
          content:
            application/json:
              schema:
                x-schema-name: User
                type: object
                properties:
                  name:
                    type: string
                  email:
                    type: string

Output

class User(Model):
    name: str | None = Field(default=None)
    email: str | None = Field(default=None)

Enum variable names

Variable names for enums can be specified by the x-enum-varnames field.

Input

components: 
  schemas:
    Direction:
      x-enum-varnames: [ NORTH, SOUTH, WEST, EAST ]
      type: string
      enum: [ N, S, W, E ]

Output

from enum import StrEnum

class Direction(StrEnum):
    NORTH = "N"
    SOUTH = "S"
    WEST = "W"
    EAST = "E"

Custom types

Input

components: 
  schemas: 
    User:
      type: object
      properties:
        name:
          type: string
        email:
          type: string
          format: email

from pathlib import Path

from spec2sdk.parsers.entities import DataType, StringDataType
from spec2sdk.generators.converters import converters
from spec2sdk.generators.entities import PythonType
from spec2sdk.generators.predicates import is_instance
from spec2sdk.generators.imports import Import
from spec2sdk.generators.models.entities import TypeRenderer

from spec2sdk.main import generate


class EmailPythonType(PythonType):
    pass


def is_email_format(data_type: DataType) -> bool:
    return isinstance(data_type, StringDataType) and data_type.format == "email"


@converters.register(predicate=is_email_format)
def convert_email_field(data_type: StringDataType) -> EmailPythonType:
    return EmailPythonType(
        name=None,
        type_hint="EmailStr",
        description=data_type.description,
        default_value=data_type.default_value,
    )


@renderers.register(predicate=is_instance(EmailPythonType))
def render_email_field(py_type: EmailPythonType) -> TypeRenderer:
    return render_root_model(
        py_type,
        extra_imports=(Import(name="EmailStr", package="pydantic"),),
        content="EmailStr",
    )


if __name__ == "__main__":
    generate(url=Path("api.yml").absolute().as_uri(), output_dir=Path("output"))

Output

from pydantic import EmailStr, Field

class User(Model):
    name: str | None = Field(default=None)
    email: EmailStr | None = Field(default=None)
