func

Func is a CLI app to simplify development and deployment of AWS Lambda functions using Go and Terraform. It'll scaffold an optionated project structure generating code for

• function code
• build and deployment automation using make
• IaaS using terraform modules (terraform-aws-lambda)
• continuous integration using GitHub actions

Func is in an early alpha stage so expect bugs and breaking changes but give it a try!
