Haskell on AWS Lambda - A Detailed Tutorial

This tutorial, along with the accompanying source-code walks you through the process of:

• managing AWS Lambda Functions completely in Haskell with the exception of an unavoidable dependency on Docker
• building a custom AWS Lambda runtime in Haskell, which is useful if you ever have requirements that aren’t already handled by the AWS Lambda Haskell Runtime
• using Docker, along with aws-lambda-packager, to compile your Haskell code for AWS Lambda, and package it along with all it’s native dependencies

Apart from that, we even share some opinions and first-hand experiences:

• Avoid using serverless-haskell
• Avoid using AWS API Gateway
• Avoid struggling with static linking
• amazonka maintenance issues
• Using the zip Haskell library
