+# JRPCServer
+
+JRPCServer is a simple library which allows you to rapidly expose a JSON response based RPC service which includes support for prometheus expont on '/metrics', registering with a Consul service if desired, and a health endpoint on '/health'.
+
+## A Simple Example
+
+```go
+package main
+
+import (
+	"flag"
+	"fmt"
+	"io"
+	"io/ioutil"
+
+	"github.com/riomhaire/jrpcserver/infrastructure/api/rpc"
+	"github.com/riomhaire/jrpcserver/model"
+	"github.com/riomhaire/jrpcserver/model/jrpcerror"
+	"github.com/riomhaire/jrpcserver/usecases/defaultcommand"
+)
+
+// A simple example 'helloworld' program to show how use the framework
+//
+// to execute (after compiling):
+//      helloworld -port=9999 -consul=consul:8500
+//
+func main() {
+
+	name := flag.String("name", "helloworld", "name of service")
+	path := flag.String("path", "/api/v1/helloworld", "Path to which to  <path>/<command>  points to action")
+	consulHost := flag.String("consul", "", "consul host usually something like 'localhost:8500'. Leave blank if not required")
+	port := flag.Int("port", 9999, "port to use")
+	flag.Parse()
+
+	config := model.DefaultConfiguration{
+		Server: model.ServerConfig{
+			ServiceName: *name,
+			BaseURI:     *path,
+			Port:        *port,
+			Commands:    Commands(),
+			Consul:      *consulHost,
+		},
+	}
+	rpc.StartAPI(config) // Start service -  wont return
+}
+
+func Commands() []model.JRPCCommand {
+	commands := make([]model.JRPCCommand, 0)
+
+	commands = append(commands, model.JRPCCommand{"example.helloworld", HelloWorldCommand, false})
+	commands = append(commands, model.JRPCCommand{"system.commands", defaultcommand.ListCommandsCommand, false})
+	return commands
+}
+
+func HelloWorldCommand(config interface{}, metadata map[string]string, payload io.ReadCloser) (interface{}, jrpcerror.JrpcError) {
+	data, err := ioutil.ReadAll(payload)
+	if err != nil {
+		return "", jrpcerror.JrpcError{500, err.Error()}
+	} else {
+		fmt.Println(string(data))
+		response := fmt.Sprintf("Hello %v", string(data))
+
+		return response, jrpcerror.JrpcError{}
+	}
+}
+
+```
+
+Hopefully this is fairly understandable (and is included within the examples/helloworld ). Essentially all you have to do is provide a list of functions and their command names and the library handles the rest.
+
+If you call (using VSCode Rest syntax)
+
+```curl
+POST http://localhost:9999/api/v1/helloworld/example.helloworld
+Content-Type: text/plain
+
+fred
+```
+
+You would receive something like:
+
+```text
+HTTP/1.1 200 OK
+Content-Type: application/json
+Vary: Origin
+X-Worker: warband
+X-Worker-Version: UNKNOWN
+Date: Mon, 17 Sep 2018 20:14:27 GMT
+Content-Length: 55
+
+{
+  "code": 0,
+  "error": "",
+  "value": "Hello fred"
+}
+```
+
+If you call:
+
+```curl
+GET http://localhost:9999/metrics
+```
+
+You would receive something like:
+
+```text
