By: 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.

Configuring API using JSON


What is an API? To put it simply, an application programming interface is a way in which we can access our application data and present it in a desired format. The API implementation grants access to its data via application requests. It can be an HTTP request or FTP. With respect to the context of our book, we are going to learn about HTTP requests.

A request basically consists of the following:

  • Unique Resource Location (URL)
  • Request headers
  • Request body

An API server provides an endpoint URL so that we can access the required info through our client, for instance, a browser. In the preceding chapters, we have already seen how node.js implements an API server with its basic core.

Let's see how hapi implements such an API on top of node.js. To discover this, consider the following code:

const Hapi = require('hapi');
const constants = require('./constants');
const port = constants.port;

const server = new Hapi.Server({
 port
});

server.route({
  method: 'GET',
  path...
