apispec-starlette 0.0.3

APISpec plugin handling Starlette.

Plugin for APISpec handling Starlette

This module should not be considered as stable as it is still under development.

However a stable version can be expected by mid March 2020 and any issue or pull request is welcome at any time.

Provides a plugin to use with APISpec to be able to handle Starlette endpoints.

StarlettePlugin usage

from starlette.applications import Starlette
from apispec import APISpec
from apispec_starlette import StarlettePlugin


app = Starlette()
spec = APISpec(
    title="My API",
    version="0.0.1",
    openapi_version="2.0",
    plugins=[StarlettePlugin(app)],
)

Documenting responses inside endpoint docstring

from starlette.applications import Starlette
from starlette.responses import JSONResponse
from apispec import APISpec
from apispec_starlette import StarlettePlugin


app = Starlette()
spec = APISpec(
    title="My API",
    version="0.0.1",
    openapi_version="2.0",
    plugins=[StarlettePlugin(app)],
)


@app.route("/my_endpoint")
def my_endpoint():
    """
    responses:
        200:
            description: "Action performed"
            schema:
                properties:
                    status:
                        type: string
                type: object
    """
    return JSONResponse({"status": "test"})

Documenting responses outside of endpoint docstring

from starlette.applications import Starlette
from starlette.responses import JSONResponse
from apispec import APISpec
from apispec_starlette import StarlettePlugin, document_response


app = Starlette()
spec = APISpec(
    title="My API",
    version="0.0.1",
    openapi_version="2.0",
    plugins=[StarlettePlugin(app)],
)


@app.route("/my_endpoint")
def my_endpoint():
    return JSONResponse({"status": "test"})


document_response(spec, endpoint="/my_endpoint", method="get", status_code=200, response={
    "description": "Action performed",
    "schema": {
        "properties": {"status": {"type": "string"}},
        "type": "object",
    }
})

Documenting OAuth2 security outside of endpoint docstring

from starlette.applications import Starlette
from starlette.middleware import Middleware
from starlette.middleware.authentication import AuthenticationMiddleware
from starlette.authentication import requires, AuthenticationBackend
from starlette.responses import JSONResponse
from apispec import APISpec
from apispec_starlette import StarlettePlugin, document_endpoint_oauth2_authentication, document_oauth2_authentication


# TODO Replace by your OAuth2 backend
app = Starlette(middleware=[Middleware(AuthenticationMiddleware, backend=AuthenticationBackend())])
spec = APISpec(
    title="My API",
    version="0.0.1",
    openapi_version="2.0",
    plugins=[StarlettePlugin(app)],
)

# TODO Adjust parameters
document_oauth2_authentication(spec, authorization_url="http://authorization_url", flow="implicit", scopes={"scope1": "Description of scope 1", "scope2": "Description of scope 2"})

@requires(scopes=["scope1", "scope2"])
@app.route("/my_endpoint")
def my_endpoint():
    return JSONResponse({"status": "test"})


document_endpoint_oauth2_authentication(spec, endpoint="/my_endpoint", method="get", required_scopes=["scope1", "scope2"])

Add a /swagger.json endpoint

Your endpoints can be automatically discovered and documented when requesting /swagger.json

from starlette.applications import Starlette
from apispec_starlette import add_swagger_json_endpoint


app = Starlette()
spec = add_swagger_json_endpoint(app=app)
