Since September 2016, API Gateway supports proxying requests to Lambda without having to set up specific handlers, methods or conversion templates. This can be a good alternative to using Claudia API Builder if you need to set up something more generic. Claudia 2.0 can automatically deploy a proxy API for your Lambda function -- just add --deploy-proxy-api when creating it.

To try out this example, use:

1. npm install to grab the dependencies
2. npm start to deploy the main.js to Lambda and create a proxy api

The procedure will print out a URL. You can send HTTP requests to it, and any sub-URLs, and get back the full request object as the response.
