gRPC in 3 minutes (Go)

BACKGROUND

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

PREREQUISITES

• This requires Go 1.5 or later
• Requires that GOPATH is set

$ 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

3 Rebuild the generated Go code.

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