aws-lambda-function-sandbox-runner

Run AWS Lambda Functions on your local computers, for testing purposes

Introduction

When you write AWS Lambda Functions, there is not a natural way to test the code in your computer or personal sandbox. This library helps you to run any AWS Lambda Function on your own environment.

Installation

npm install aws-lambda-function-sandbox-runner

Real World example:

mkdir testing
cd testing
touch mylambda.js//edit and put the content showed below
npm install aws-lambda-function-sandbox-runner
node node_modules/aws-lambda-function-sandbox-runner/run.js mylambda

You should see this:

AWS Lambda Function was executed without issues.
Output: worked!

content of mylambda.js:

exports.handler = function(event, context) {
  context.succeed('worked!');
};

Deployment of your Lambda Function

Some Node.js plugins do the deployment of your code via aws cli, I don't suggest you that, because you are missing testing coverage and continuous integration. I suggest you to use a continous integration like travis that deploys your code to Amazon S3 and to link your Lambda Function to the S3 bucket of your code.
