LambdaBase

Base library to create Elixir AWS Lambda

Installation

The package can be installed by adding lambda_base to your list of dependencies in mix.exs:

def deps do
  [
    {:lambda_base, "~> 1.0.2"}
  ]
end

Basic Usage

1. Create Lambda module. Implement handle(event, context) function.

defmodule UpCase do
  use LambdaBase
  @impl LambdaBase
  def handle(event, context) do
    {:ok, event |> Json.encode |> String.upcase}
  end
end

1. Create zip file for AWS Lambda.

$ docker run -d -it --name elx erintheblack/elixir-lambda-builder:20200112.01
$ docker cp ${project} elx:/tmp
$ docker exec elx /bin/bash -c "cd /tmp/${project}; mix deps.get; mix lambda.release"
$ docker cp elx:/tmp/${app_name}.zip .

1. Upload zip file and set configuration.

• Set Module Name to handler.
• Set Log level to environment -> LOG_LEVEL
