A little library to simplify building small APIs on top of AWS Lambda and API Gateway.
This library is still in development. It is sufficient for ProdPerfect's needs but it may not be for yours. Use at your own risk.
- Python 3.9+
- Blinker 1.4+
pip install deez
Your resource must implement at least one HTTP verb (get, post, put, etc.,)
from deez.resource import Resource
from deez.response import JsonResponse
class MyResource(Resource):
def get(self, request, *args, **kwargs):
return JsonResponse(data={'message': 'hello world'})app.py
from deez import Deez
from deez.resource import Resource
from deez.response import JsonResponse
from deez.urls import path
class HelloWorldView(Resource):
def get(self, request, *args, **kwargs):
return JsonResponse(data={'message': 'hello world'})
app = Deez()
app.register_route(path("hello/world", HelloWorldView))
# or you can use regex
app.register_route(r'^hello/world$', HelloWorldView)
`middleware.py`
```python
from deez.middleware import Middleware
class User:
# fake user object
pass
class AuthMiddleware(Middleware):
def before_request(self, request):
# perhaps you want to authenticate the user and attach it to the request object
request.user = User()
return requestsettings.py
# middleware runs before views are called and before the response is returned
# so you can manipulate the response and requests objects.
MIDDLEWARE = ['middleware.AuthMiddleware']handler.py
from app import app
def handle_event(event, context):
return app.process_request(event, context)Deez supports signals. Signals are a way to hook into the request/response lifecycle. This can be useful for logging metrics or doing other things such as managing database connections.
from deez.core.signals import request_finished, request_started
@request_started.connect
def my_callback(sender, **kwargs):
print('request started')
@request_finished.connect
def my_other_callback(sender, **kwargs):
print('request finished')See the examples directory for a working example.
