Requires node version 8.x.x. The compatibility of this library should match the node LTS release schedule, since that is the version used by Google Cloud Functions.
The client class should be used in response to a http trigger.
Initiating it takes two arguments: the request and response objects passed to the GCP function.
The instance has two methods:
Stands for a valid response. Responds with a JSON object. Can optionally include a status code (defaults to 200).
Responds with an error.
The funcional library also includes an interface to interact with GCP functions in the server.
Rename as funcional.
