Lambda offline support in Zappa?

[kpx-dev]

Hey guys,

Awesome project! I want to be able to run and test my Zappa setup locally and simulate AWS Lambda request, how can I do it currently?

Ex Use Case: lambda function watching for new S3 put object. I can simulate that from AWS UI, but don't know how to do it within Zappa.

Thanks.

This is an excellent question!

It is probably a non-trivial task, but do able. We will likely need to use other frameworks to make this possible, for instance: https://github.com/fugue/emulambda, and I think there may be other similar initiatives we should investigate.

What would your workflow for something like this look like? What's the syntax/API you'd want?

Hi @Miserlou,

I think be able to transparently run my lambda function locally and get debugging output offline would be best. Now if Zappa have to upload to AWS Lambda and execute it, that's fine, but I would love to be able to debug my Python app offline like a regular app.
