Types

type GraphqlField 

type GraphqlField struct {

	// If true, this field is required.
	Required bool `protobuf:"varint,1,opt,name=required,proto3" json:"required,omitempty"`
	// Use as other field name (not recommend)
	Name string `protobuf:"bytes,2,opt,name=name,proto3" json:"name,omitempty"`
	// Define default value on input.
	Default string `protobuf:"bytes,3,opt,name=default,proto3" json:"default,omitempty"`
	// Omit this field from graphql definition
	Omit bool `protobuf:"varint,4,opt,name=omit,proto3" json:"omit,omitempty"`
	// Resolve this field by nested query with additional RPC
	Resolver string `protobuf:"bytes,5,opt,name=resolver,proto3" json:"resolver,omitempty"`
	// contains filtered or unexported fields
}

GraphqlField is FieldOptions in protobuf in order to define type field attribute. User can use this option as following: 

message Member {
  string name = 1 [(graphql.field) = {required: true}]; // this field is required in GraphQL, it equivalent to String! on GraphQL
}

message CreateMemberRequest {
  string name = 1; [(grahpql.field) = {default: "anonymous"}]; // use default value on input or query
}

Note that in protobuf, all fields are dealt with optional so the same as it, all GraphQL fields are optional as default. If you need to be required, use 'required: true' option

type GraphqlSchema 

type GraphqlSchema struct {

	// graphql type. Enum of QUERY or MUTATION is valid value
	Type GraphqlType `protobuf:"varint,1,opt,name=type,proto3,enum=graphql.GraphqlType" json:"type,omitempty"`
	// query name. this field is required
	Name string `protobuf:"bytes,2,opt,name=name,proto3" json:"name,omitempty"`
	// Query request object configuration
	Request *GraphqlRequest `protobuf:"bytes,3,opt,name=request,proto3" json:"request,omitempty"`
	// Query response object configuration
	Response *GraphqlResponse `protobuf:"bytes,4,opt,name=response,proto3" json:"response,omitempty"`
	// contains filtered or unexported fields
}

Extend MethodOptions in order to define GraphQL Query or Mutation. User can use this option as following: 

service Greeter {
   rpc SayHello(HelloRequest) returns (HelloReply) {
     option (graphql.schema) = {
       type: QUERY    // declare as Query
       name: "hello"  // query name
     }
   }
}

Since gRPC reason, it has limitation that the response could not be repeated. it's dificcurl to respond array response, so that we accept "response.pluck" in order to expose repeated fields in response message.

For instance: 

message Member {
  string name = 1;
}

message ListMembersResponse {
  repeated Member members = 1; -- could be array response
}

message ListMembersRequest { } 

service MemberService {
   rpc ListMembers(ListMembersRequest) returns (ListMembersResponse) {
     option (graphql.schema) = {
       type: QUERY
       name: "members"
       response {
         repeated : true
         pluck: "members" // Query will respond [Member] instead of ListMembersResponse
       }
     }
   }
}

In mutation declaration: 

service MemberService {
   rpc CreateMember(CreateMemberRequest) returns (Member) {
     option (graphql.schema) = {
       type: MUTATION        // declare as Mutation
       name: "cretemember"   // mutation name
     }
   }
}

The Mutation's input always becomes an input object, so you need to declare argument name. 

message Member {
  string name = 1;
}

message CreateMemberRequest {
  string name = 1;
}

service MemberService {
   rpc CreateMember(CreateMemberRequest) returns (Member) {
     option (graphql.schema) = {
       type: MUTATION
       name: "createmember"
       request {
         name: "member" // this is equivalent to createbook(member: Member): Member in GraphQL
       }
     }
   }
}

Finally, user can access this query via /graphql?query={members{name}}

	// If true, automatic connection with insecure option.
	Insecure bool `protobuf:"varint,2,opt,name=insecure,proto3" json:"insecure,omitempty"`
	// contains filtered or unexported fields
}

Extend ServiceOptions in order to define grpc connection setting. User can use this option as following: 

service Greeter {
   option (graphql.service) = {
     host: "localhost:50051" // define grpc connection host and port
     insecure: true          // set true if connect to insecure grpc server
   };

   ... some rpc definitions
