Fully featured framework for fast, easy and documented API development with Sanic

Project description

Sanic-RESTPlus is an extension for Sanic that adds support for quickly building REST APIs. Sanic-RESTPlus encourages best practices with minimal setup. If you are familiar with Sanic, Sanic-RESTPlus should be easy to pick up. It provides a coherent collection of decorators and tools to describe your API and expose its documentation properly using Swagger.

Compatibility

Sanic-RestPlus requires Python 3.5+. Sanic-RestPlus works with Sanic v18.12+

Important Compatibility Notice

Sanic-RestPlus version 0.4.1 (and previous versions) does not work on Sanic 19.12+, see this bug here: https://github.com/ashleysommer/sanicpluginsframework/issues/15

Please use latest Sanic-Restplus (v0.5.3 or greater) if you need to deploy on Sanic v19.12+.

If you are using the new Sanic v20.12LTS, please use Sanic-RestPlus v0.5.5 or greater.

Installation

In the near future, you will be able to install Sanic-Restplus with pip:

$ pip install sanic-restplus

or with easy_install:

$ easy_install sanic-restplus

Quick start

With Sanic-Restplus, you only import the api instance to route and document your endpoints.

from sanic import Sanic
from sanic_restplus import Api, Resource, fields
from sanic_restplus.restplus import restplus
from spf import SanicPluginsFramework
app = Sanic(__name__)
spf = SanicPluginsFramework(app)
rest_assoc = spf.register_plugin(restplus)

api = Api(version='1.0', title='TodoMVC API',
          description='A simple TodoMVC API')

ns = api.namespace('todos', description='TODO operations')

todo = api.model('Todo', {
    'id': fields.Integer(readOnly=True, description='The task unique identifier'),
    'task': fields.String(required=True, description='The task details')
})


class TodoDAO(object):
    def __init__(self):
        self.counter = 0
        self.todos = []

    def get(self, id):
        for todo in self.todos:
            if todo['id'] == id:
                return todo
        api.abort(404, "Todo {} doesn't exist".format(id))

    def create(self, data):
        todo = data
        todo['id'] = self.counter = self.counter + 1
        self.todos.append(todo)
        return todo

    def update(self, id, data):
        todo = self.get(id)
        todo.update(data)
        return todo

    def delete(self, id):
        todo = self.get(id)
        self.todos.remove(todo)


DAO = TodoDAO()
DAO.create({'task': 'Build an API'})
DAO.create({'task': '?????'})
DAO.create({'task': 'profit!'})


@ns.route('/')
class TodoList(Resource):
    '''Shows a list of all todos, and lets you POST to add new tasks'''

    @ns.doc('list_todos')
    @ns.marshal_list_with(todo)
    async def get(self, request):
        '''List all tasks'''
        return DAO.todos

    @ns.doc('create_todo')
    @ns.expect(todo)
    @ns.marshal_with(todo, code=201)
    async def post(self, request):
        '''Create a new task'''
        return DAO.create(request.json), 201


@ns.route('/<id:int>')
@ns.response(404, 'Todo not found')
@ns.param('id', 'The task identifier')
class Todo(Resource):
    '''Show a single todo item and lets you delete them'''

    @ns.doc('get_todo')
    @ns.marshal_with(todo)
    async def get(self, request, id):
        '''Fetch a given resource'''
        return DAO.get(id)

    @ns.doc('delete_todo')
    @ns.response(204, 'Todo deleted')
    async def delete(self, request, id):
        '''Delete a task given its identifier'''
        DAO.delete(id)
        return '', 204

    @ns.expect(todo)
    @ns.marshal_with(todo)
    async def put(self, request, id):
        '''Update a task given its identifier'''
        return DAO.update(id, request.json)

rest_assoc.api(api)

if __name__ == '__main__':
    app.run(debug=True, auto_reload=False)
