This is a sample template for a serverless AWS Lambda application, written in Node.js.
This application contains two Lambda Functions. The getWelcomePage function responds to web request events from an API Gateway endpoint. The logErrors function processes a centralized stream of all Lambda errors within this app.
The application architecture is defined in template.yaml, a Serverless Application Model (SAM) template which can be managed through the Stackery UI at app.stackery.io.
