Go gRPC Demo

Installation

git clone git@github.com:seifkamal/go-grpc-demo.git
cd go-grpc-demo
go get -u

After cloning the repo, download a suitable prebuilt binary version of the compiler from https://github.com/protocolbuffers/protobuf/releases and compile the proto/service.proto definition file.

Example:

# --proto_path=proto - Directory where the proto definition is located
# --proto_path=include - Directory that comes with the compiler (used to generate the Go code)
# --go_out=plugins=grpc:proto - Use protoc-gen-go to generate code compatible with gRPC (see https://github.com/golang/protobuf#grpc-support)
protoc --proto_path=proto --proto_path=include --go_out=plugins=grpc:proto service.proto

Usage

Server

Run a server instance:

go run server.go

This will open a TCP connection over port 4040.

Client

You can connect to the server via a client of your choice, or optionally run a client instance:

go run client/client.go

This will start an HTTP server on port 8080, with the following endpoints:

• /add/:a/:b
• /multiply/:a/:b
