# Description
The route guide server and client demonstrate how to use grpc go libraries to
perform unary, client streaming, server streaming and full duplex RPCs.
Please refer to [gRPC Basics: Go] (http://www.grpc.io/docs/tutorials/basic/go.html) for more information.
See the definition of the route guide service in proto/route_guide.proto.
# Run the sample code
To compile and run the server, assuming you are in the root of the route_guide
folder, i.e., .../examples/route_guide/, simply:
```sh
$ go run server/server.go
```
Likewise, to run the client:
```sh
$ go run client/client.go
```
# Optional command line flags
The server and client both take optional command line flags. For example, the
client and server run without TLS by default. To enable TLS:
```sh
$ go run server/server.go -tls=true
```
and
```sh
$ go run client/client.go -tls=true
```
