The JSON Structures

In Chapter 1, Getting Started with JSON, you were introduced to basic JSON, how JSON objects can be embedded into an HTML file, and how basic operations such as accessing keys can be performed on simple JSON objects. Now it's time to move ahead with some simple yet advanced steps. In this chapter, you will learn about:

Inserting external JavaScript
Accessing multilevel JSON objects
Performing modifications in JSON data

Now let's take a step forward and work with JSON objects that are bigger, more complex, and closer to the JSON that we would work with in real-world situations.

Key benefits

Use JSON with trending technologies like Angular, Hapi.js, MongoDB, Kafka, and Socket.io

Debug, validate, and format JSON using developer toolkits, JSONLint, and JSON Editor Online

Explore other JSON formats like GeoJSON, JSON-LD, BSON, and MessagePack

Description

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.
