Chalice: Need a way of running the Lambda service locally

[marvinpinto]

This would be great for testing and iterating locally, vs deploying and then validating.

(I couldn't find any references to this in the docs or source code, so apologies if this is already a feature)

I agree, thanks for the feature request. This is something I plan on adding.

yes! please do, i boiler-plated it under flask, but it flask uses <> brackets for url params and accesses url params differently - bleh wasted 2 hours.

something please! soon please!

[kousuke-takeuchi]

Yes! And I wanna create custom class to execute just like python app.py runserver or python app.py test --with-report

[sscarduzio]

this is super urgent for IRL usage of this framework, deploying takes forever and error messages in remote logs are super generic (no exception propagation)

[jamesls]

https://github.com/awslabs/chalice/pull/147 has been merged, which adds support for chalice local. I'll have a release out soon, try it out and let me know if you have any feedback.

Btw, the rationale for not propagating exceptions by default is so that you don't leak internal information in your error responses. You can set app.debug = True in your app.py file, and the exceptions will propagate back to you.

That being said, hopefully chalice local makes this unnecessary :)
