This repo contains the API Gateway written in Fall of 2015 It provides the following capabilities:
- Easy registration of services
- Universal Authentication for the entire application - via an external authentication provided (Atlassian crowd)
- Proxying API calls
- Managing inter-service communication
When registering as service specify the data encoding and when requesting a resource though groot make the request using json.
Add the API spec in a new file (ex. todo.go) in the services package
There is a set of proxy api calls defined by the Arbor framework which the API Gateway is written in.
