flask-lambda-support 0.1.1

Python 3.6+ module to make Flask compatible with AWS Lambda

Write Flask applications that support being run in in AWS Lambda behind API Gateway.

This project was forked from: https://github.com/techjacker/flask-lambda

Improvements:

• Expose original input event from AWS on Flask’s request object

• Production-grade logging

Requirements

• Python 3.6+

• Flask 0.10+

Installation

pip install flask-lambda-support

Usage

Here is an example of what a Flask app using this library would look like:

from flask_lambda import FlaskLambda

app = FlaskLambda(__name__)


@app.route('/foo', methods=['GET', 'POST'])
def foo():
   data = {
       'form': request.form.copy(),
       'args': request.args.copy(),
       'json': request.json
   }
   return (
       json.dumps(data, indent=4, sort_keys=True),
       200,
       {'Content-Type': 'application/json'}
   )


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

You can access the original input event on the Flask request context:

from flask import request

assert request.aws_event['input']['httpMethod'] == 'POST'
