pymiddy 0.1.0

PyMiddy

Heavily inspired from middyjs.

Quick start

from pymiddy import Middy
from pymiddy.middlewares import CORS

@Middy
def handler(event, context):
    return {
        'statusCode': 200,
        'body': 'lorem ipsum dolor sit amet'
    }


handler.use(TestMiddleware(1)) \
    .use(CORS({
        'credentials': True,
        'origins': ['https://website.xyz/']
    }))

Custom middlewares

A middleware class should have 3 methods:

class MyCustomMiddleware(object):
    def before(self, state):
        pass

    def after(self, state):
        pass

    def error(self, state):
        pass

The state contains the following keys:

• event - the event which triggered the lambda function, passed from the aws handler
• context - the context from the aws handler
• response - the handler response, if any
• exception - during error handler you can have access to this key which contains the exception which triggered the error
