  services: [
    {filename: 'helloworld.proto'},
  ]
};

const root = '/'; // or '/<someOtherRoot>'

proxy = watcher({grpcClient: {ggConf: {root: '.proto'}, clientConf});
app.use(root, proxy);

app.listen(3000);

client.js:

const {body} = await = request.post({
  url: `localhost:3000/proxy/gnat.helloworld.Greeter/SayHello`, // '<host>:<port>/<rootUrl>/proxy/<servicePath>/<methodName>'
  body: {args: {name: 'World'}, /* metadata: {}, callOpts: {} */},
