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 First install protoc

  • For now, this needs to be installed from source
  • This is will change once proto3 is officially released

2 Install the protoc Go plugin.

$ go get -a github.com/golang/protobuf/protoc-gen-go
$
$ # from this dir; invoke protoc
$  protoc -I ./helloworld/helloworld/ ./helloworld/helloworld/helloworld.proto --go_out=plugins=grpc:helloworld
