Using protobuf-v3

Protobuf v3 comes with pretty nice definition that normally used for GRPC, including

• Solid data types
• Quite known pre-defined format
• Service definition ready

Current state

• Define structure
• Code skeleton for protobuf generator
• Define golang implementation
• Define typescript implementation
• Tests
• Incorporate tracing and monitoring into the implementations

How to run example

• Go installed
• Make sure probuffer installed (can install using brew install protobuf)
• Confirm the installation by having protoc in code
• Execute generate.sh from root dir (can also use go generate todo ...)

Noted (naming proto file is matter)

• We decided only gen action methods and their listener when the proto file contant app or bff. The reason behind it is we encounrage every one (especial FE code) to access the service via bff not call service dirrectly.

Option Examples:

• [(goff.custom) = '']
  • validate: from https://github.com/go-playground/validator.
    • Example: [(goff.custom) = 'validate:"notblank"'], [(goff.custom) = 'validate:"required,oneof=MEMBER PATIENT ORGANIZATION"']
  • customize struct tags:
    • Example: [(goff.custom) = 'json:"omitempty"'];
• [(goff.nullable) = true] //Set basic type to pointer.
• goff.Empty
  • rpc getAllDevices (goff.Empty) returns (AdminDevicesDto) =>func getAllDevices() (AdminDevicesDto, error)
  • rpc getAllDevices (Model) returns (goff.Empty) =>func getAllDevices(Model) (error)
• Mix options: [(goff.custom) = 'json:"gender,omitempty"', (goff.nullable) = true];
