# GRPC Server
The grpc server is a [micro.Server](https://godoc.org/github.com/micro/go-micro/server#Server) compatible server.
## Overview
The server makes use of the [google.golang.org/grpc](google.golang.org/grpc) framework for the underlying server
but continues to use micro handler signatures and protoc-gen-micro generated code.
## Usage
Specify the server to your micro service
```go
import (
"github.com/micro/go-micro"
"github.com/micro/go-plugins/server/grpc"
)
func main() {
service := micro.NewService(
// This needs to be first as it replaces the underlying server
// which causes any configuration set before it
// to be discarded
micro.Server(grpc.NewServer()),
micro.Name("greeter"),
)
}
```
**NOTE**: Setting the gRPC server and/or client causes the underlying the server/client to be replaced which causes any previous configuration set on that server/client to be discarded. It is therefore recommended to set gRPC server/client before any other configuration
