sippycup 0.3.0

Serverless nanoframework for AWS API Gateway and AWS Lambda

Sippy Cup is an extremely minimalistic Python framework to quickly create serverless applications using AWS API Gateway and AWS Lambda.

Sippy Cup converts the input format sent to an AWS Lambda function by API Gateway into a WSGI environment to provide a set of Werkzeug-based request and response objects, converting the latter to the return format expected by API Gateway.

It is intended to be similar in use to Python frameworks such as Flask and Chalice, although it has a significantly smaller feature set by design.

Getting started

Installation

Because you will eventually need to create a deployment package, it is highly recommended that you use a virtualenv when using Sippy Cup.

pip install sippycup

Create a simple application

lambda_function.py provides a demo application

# lambda_function.py

from sippycup import SippyCup

app = SippyCup()


@app.route('/hello/<string:name>', methods=['GET', 'POST'])
@app.mimetype('text/plain')
def hello_world(name='World'):
    return 'Hello, {0}!'.format(name)


@app.route('/')
def index():
    # return the original event sent to Lambda from API Gateway
    return app.request.apigr


lambda_handler = app.run

if __name__ == '__main__':
    from werkzeug.serving import run_simple
    run_simple(
        '127.0.0.1', 5000, lambda_handler, use_debugger=True, use_reloader=True
    )

You will need to create a deployment package and use that to create a new AWS Lambda function.

Finally, set up an API Gateway proxy resource with the lambda proxy integration. It is recommended to create resources on both ‘/’ and ‘/SOMEPREFIX’ unless you don’t need the ‘/’ route.
