As an alternative to the Claudia API Builder request, you can also use the API Gateway Proxy Request object directly. To do that, pass the AWS_PROXY format as the requestFormat option to the constructor when instantiating the API builder.
var ApiBuilder = require('claudia-api-builder'),
api = new ApiBuilder({requestFormat: 'AWS_PROXY'});
api.get('/', request => {
// request is now the raw API Gateway proxy object
// not the API Builder replacement
});
