JavaScript and JSON Essentials - Second Edition

By: Bruno Joseph D'mello, Sai S Sriparasa

Overview of this book

JSON is an established and standard format used to exchange data. This book shows how JSON plays different roles in full web development through examples. By the end of this book, you'll have a new perspective on providing solutions for your applications and handling their complexities. After establishing a strong basic foundation with JSON, you'll learn to build frontend apps by creating a carousel. Next, you'll learn to implement JSON with Angular 5, Node.js, template embedding, and composer.json in PHP. This book will also help you implement Hapi.js (known for its JSON-configurable architecture) for server-side scripting. You'll learn to implement JSON for real-time apps using Kafka, as well as how to implement JSON for a task runner, and for MongoDB BSON storage. The book ends with some case studies on JSON formats to help you sharpen your creativity by exploring futuristic JSON implementations. By the end of the book, you'll be up and running with all the essential features of JSON and JavaScript and able to build fast, scalable, and efficient web applications.

Basic server setup using JSON


In Chapter 7, Alternate Implementations of JSON, we already scaffolded a Node server while we worked on the template embedding section. We can either modify it or create a new app. If you are planning to use the same app, you need to do the following:

  • Modify the app.js
  • Eliminate template-related implementation

After modification, we get following structure in our code base:

Just to get a brief idea about the preceding code, we created a simple HTTP server. The createServer method contains the request parameters req to handle the incoming request and the response instance for the outgoing response to and from the server respectively. We are using the end method of the response object to send response data as Hello readers to the client.

Let's go through proper stepwise procedure as shown as follows:

  1. First let us install the hapi framework using the following command; we install a version greater than or equal to v17.x.x. By default, the package manager will install...
