Locked / do not touch REST API services and express federation serverMarch 16, 2020 at 4:08pm
I am working with a collection of micro services via Apollo federation express server. For business reasons there are two services that have a well documented REST API that we can query BUT are not able to be edited/changed.
Any hints or pointers?
I would preferably like to just add some type defs and resolvers to the Federation gateway and then at some point in the future get into services
