Examples

1. Defines variables in FederationService

grpc-federation/_examples/11_multi_service/proto/federation/federation.proto

Lines 29 to 42 in 7a50f0b

	var {
	name: "upper_name"
	by: "grpc.federation.strings.toUpper(grpc.federation.env.name)"
	}
	var {
	name: "federation_service_variable"
	by: "1"
	}
	var {
	validation {
	if: "grpc.federation.env.name == ''"
	message: "'name environment variable is unspecified'"
	}
	}

2. Defines variables in PrivateService

grpc-federation/_examples/11_multi_service/proto/federation/federation.proto

Lines 63 to 94 in 7a50f0b

	var {
	name: "upper_name"
	by: "grpc.federation.strings.toUpper(grpc.federation.env.name)"
	}
	var {
	name: "private_service_enum"
	enum {
	name: "MyFavoriteType"
	by: "favorite.FavoriteType.value('TYPE_1')"
	}
	}
	var {
	name: "private_service_user"
	message {
	name: "User"
	args [
	{name: "id" by: "'private_service_user_id'"},
	{name: "name" by: "'private_service_user_name'"}
	]
	}
	}
	var { name: "users" by: "[private_service_user]"}
	var {
	name: "private_service_user_names"
	map {
	iterator {
	name: "iter"
	src: "users"
	}
	by: "iter.name"
	}
	}

3. Use common upper_name variable

grpc-federation/_examples/11_multi_service/proto/federation/federation.proto

Line 115 in 7a50f0b

string upper_name = 2 [(grpc.federation.field).by = "grpc.federation.var.upper_name"];
