sanic-openapi's Introduction

Sanic OpenAPI

Give your Sanic API a UI and OpenAPI documentation, all for the price of free!

Installation

pip install sanic-openapi

Add OpenAPI and Swagger UI:

from sanic_openapi import swagger_blueprint, openapi_blueprint

app.blueprint(openapi_blueprint)
app.blueprint(swagger_blueprint)

You'll now have a Swagger UI at the URL /swagger.
Your routes will be automatically categorized by their blueprints.

Example

For an example Swagger UI, see the Pet Store

Usage

Use simple decorators to document routes:

from sanic_openapi import doc

@app.get("/user/<user_id:int>")
@doc.summary("Fetches a user by ID")
@doc.produces({ "user": { "name": str, "id": int } })
async def get_user(request, user_id):
    ...

@app.post("/user")
@doc.summary("Creates a user")
@doc.consumes({"user": { "name": str }}, location="body")
async def create_user(request):
    ...

Model your input/output

class Car:
    make = str
    model = str
    year = int

class Garage:
    spaces = int
    cars = [Car]

@app.get("/garage")
@doc.summary("Gets the whole garage")
@doc.produces(Garage)
async def get_garage(request):
    return json({
        "spaces": 2,
        "cars": [{"make": "Nissan", "model": "370Z"}]
    })

Get more descriptive

class Car:
    make = doc.String("Who made the car")
    model = doc.String("Type of car.  This will vary by make")
    year = doc.Integer("4-digit year of the car", required=False)

class Garage:
    spaces = doc.Integer("How many cars can fit in the garage")
    cars = doc.List(Car, description="All cars in the garage")

Configure all the things

app.config.API_VERSION = '1.0.0'
app.config.API_TITLE = 'Car API'
app.config.API_DESCRIPTION = 'Car API'
app.config.API_TERMS_OF_SERVICE = 'Use with caution!'
app.config.API_PRODUCES_CONTENT_TYPES = ['application/json']
app.config.API_CONTACT_EMAIL = '[email protected]'
