Introduction

It's a basic Hello World grpc Api where we have a server and a client. To run the application first boot up the server by running the server.js file. When server is up and running, we can run the client application to send request to server and get response. Steps are as follows Open an instance of terminal and run the following commands

    npm build ./src/
    node ./src/server.js

Open another instance of terminal and run the following command

    node ./src/client.js

On running the client file, you'll get the following response

{ "message": "Hello World" }
