Usage

Installation

1. Install plugin

npm install --save-dev serverless-bash-plugin

Adding your lambdas

Add a function to the functions section of your serverless.yml file

functions:
  echo:
    handler: src/echo.sh
    runtime: provided.al2

The plugin will detect lambda handlers ending in .sh extension.

Example echo handler:

handler () {
  response=$1
}

The generated Bash script will call handler function and pass the request body as a first parameter, also available as variable request. Set the response string to the response variable.
