AWS.Lambda.RuntimeAPI

Contents

Description

Based on the logic as implemented in https://github.com/awslabs/aws-lambda-cpp

Synopsis

Entry points

defaultMain :: (Request -> IO Response) -> IO () Source #

Default main to implement AWS Lambda using Runtime API

jsonMain :: (FromJSON a, ToJSON b) => (GenRequest a -> IO b) -> IO () Source #

Like defaultMain but work with JSON

Mocks

autoMockMain :: Mock -> (Request -> IO Response) -> IO () Source #

Check the existence of AWS_LAMBDA_RUNTIME_API environment variable.

If it exists, assume we are running in AWS Lambda environment, i.e. run normally. Otherwise use supplied MockOptions

autoMockJsonMain :: (FromJSON a, ToJSON b) => GenMock a -> (GenRequest a -> IO b) -> IO () Source #

Like autoMockMain but works with JSON

data GenMock a Source #

How to mock the Request, what to do with the Response.
