Running Express apps in AWS Lambda

This is a simple example that shows how to deploy an existing Express application, with minimal changes, to AWS Lambda.

Running the example

1. run npm install to grab the dependencies
2. run npm run generate-proxy to create a simple proxy API for the express app
3. run npm run deploy to send everything up to AWS Lambda

The third step will print out a URL you can use to access the express app.

Updating the app

1. Change app.js
2. (Optionally) use npm install <PACKAGE NAME> -S to install additional dependencies (always save them to package.json using -S)
3. Run npm run update to send the new version up to AWS. No need to generate the proxy again
