**flask-apispec** is a lightweight tool for building REST APIs in Flask. **flask-apispec** uses webargs_ for request parsing, marshmallow_ for response formatting, and apispec_ to automatically generate Swagger markup. You can use **flask-apispec** with vanilla Flask or a fuller-featured framework like Flask-RESTful_.

Install
-------

.. code-block::

pip install flask-apispec

Quickstart
----------

.. code-block:: python

from flask import Flask
from flask_apispec import use_kwargs, marshal_with

from marshmallow import fields, Schema

from .models import Pet

app = Flask(__name__)

class PetSchema(Schema):
class Meta:
fields = ('name', 'category', 'size')

@app.route('/pets')
@use_kwargs({'category': fields.Str(), 'size': fields.Str()})
@marshal_with(PetSchema(many=True))
def get_pets(**kwargs):
return Pet.query.filter_by(**kwargs)

**flask-apispec** works with function- and class-based views:

.. code-block:: python

from flask import make_response
from flask_apispec.views import MethodResource

class PetResource(MethodResource):

@marshal_with(PetSchema)
def get(self, pet_id):
return Pet.query.filter(Pet.id == pet_id).one()

@use_kwargs(PetSchema)
@marshal_with(PetSchema, code=201)
def post(self, **kwargs):
return Pet(**kwargs)

@use_kwargs(PetSchema)
@marshal_with(PetSchema)
def put(self, pet_id, **kwargs):
pet = Pet.query.filter(Pet.id == pet_id).one()
pet.__dict__.update(**kwargs)
return pet

@marshal_with(None, code=204)
def delete(self, pet_id):
pet = Pet.query.filter(Pet.id == pet_id).one()
pet.delete()
return make_response('', 204)

**flask-apispec** generates Swagger markup for your view functions and classes. By default, Swagger JSON is served at `/swagger/`, and Swagger-UI at `/swagger-ui/`.

.. code-block:: python

from apispec import APISpec
from flask_apispec.extension import FlaskApiSpec

spec = APISpec(
title='pets',
version='v1',
plugins=['apispec.ext.marshmallow'],
)
docs = FlaskApiSpec(app, spec)

docs.register(get_pets)
docs.register(PetResource)

Notes
-----

**flask-apispec** isn't stable yet, and the interface and internals may change. Bug reports and pull requests are much appreciated.

**flask-apispec** is strongly inspired by Flask-RESTful_ and Flask-RESTplus_, but attempts to provide similar functionality with greater flexibility and less code.
