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
- Using the latest JavaScript language features without waiting for AWS to provide new Node environments.
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.
