README

gRPC in 3 minutes (Go)

BACKGROUND

For this sample, we've already generated the server and client stubs from helloworld.proto.

PREREQUISITES

$ go help gopath
$ # ensure the PATH contains $GOPATH/bin
$ export PATH=$PATH:$GOPATH/bin

INSTALL

$ go get -u google.golang.org/grpc/examples/helloworld/greeter_client
$ go get -u google.golang.org/grpc/examples/helloworld/greeter_server

TRY IT!

  • Run the server

    $ greeter_server &
    
  • Run the client

    $ greeter_client
    

OPTIONAL - Rebuilding the generated code

  1. Install protobuf compiler

  2. Install the protoc Go plugin

    $ go get -u github.com/golang/protobuf/protoc-gen-go
    
  3. Rebuild the generated Go code

    $ go generate google.golang.org/grpc/examples/helloworld/...
    

    Or run protoc command (with the grpc plugin)

    $ protoc -I helloworld/ helloworld/helloworld.proto --go_out=plugins=grpc:helloworld
