Mastering Node.js - Second Edition

By: Sandro Pasquali, Kevin Faaborg

Overview of this book

Node.js, a modern development environment that enables developers to write server- and client-side code with JavaScript, thus becoming a popular choice among developers. This book covers the features of Node that are especially helpful to developers creating highly concurrent real-time applications. It takes you on a tour of Node's innovative event non-blocking design, showing you how to build professional applications. This edition has been updated to cover the latest features of Node 9 and ES6. All code examples and demo applications have been completely rewritten using the latest techniques, introducing Promises, functional programming, async/await, and other cutting-edge patterns for writing JavaScript code. Learn how to use microservices to simplify the design and composition of distributed systems. From building serverless cloud functions to native C++ plugins, from chatbots to massively scalable SMS-driven applications, you'll be prepared for building the next generation of distributed software. By the end of this book, you'll be building better Node applications more quickly, with less code and more power, and know how to run them at scale in production environments.

Using Twilio to create an SMS bot on Heroku

We are going to be building an application that works as a customer service application, whereby customer service agents can field SMS requests from customers and respond to them. There will be two parts to the system.

  • Part 1 : A client application, running on your local machine, which spins up a React-powered web interface that displays incoming SMS messages, indicates the sentiment of the message (is the customer angry? Happy?) and allows you to respond to the message. Note that even though this server is running on a local machine, it could just as well be deployed to Heroku, or somewhere else -- the goal is to demonstrate how many servers in different locations can intelligently communicate with each other.
  • Part 2 : A switchboard that fields messages arriving via the Twilio SMS gateway, processes them, and distributes messages across...
