Function compiled with Babel

This example demonstrates how to compile your JavaScript code with Babel. In order to do so the serverless-babel-plugin is leveraged.

Use Cases

Setup

npm install

Deploy

serverless deploy
Serverless: Deprecation Notice: Starting with the next update, we will drop support for Lambda to implicitly create LogGroups. Please remove your log groups and set "provider.cfLogs: true", for CloudFormation to explicitly create them for you.
