JavaScript and JSON Essentials - Second Edition

<JavaScript and JSON Essentials - Second Edition> ▶Book 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.

▶What You Will Learn
⦁ Use JSON to store metadata for dependency managers, package managers, configuration managers, and metadata stores
⦁ Handle asynchronous behavior in applications using callbacks, promises, generators, and async-await functions
⦁ Use JSON for Angular 5, Node.js, Gulp.js, and Hapi.js
⦁ Implement JSON as BSON in MongoDB
⦁ Make use of JSON in developing automation scripts
⦁ Implement JSON for realtime using socket.io and distributed systems using Kafka

▶Key Features
⦁ 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

▶Who This Book Is For
If you're a web developer with a basic understanding of JavaScript and want to write JSON data, integrate it with RESTful APIs to create faster and scalable applications, this book is for you.

▶What this book covers
⦁ Chapter 1, Getting Started with JSON, introduces the audience to JSON, discusses the history of JSON along with how it works and stores itself in memory. The chapter also outlines the popular programming languages that support JSON and ends by writing a basic program with different data types in JSON.
⦁ Chapter 2, The JSON Structures, spices up the normal implementation of JSON with a little complexity consisting of multiple datatypes, multiple objects, and multidimensional data.
⦁ Chapter 3, AJAX Requests with JSON, discusses AJAX requests with JSON data, passing JSON over HTTP requests, asynchronicity and techniques to handle it.
⦁ Chapter 4, Cross-Domain Asynchronous Requests, explores the concept of making asynchronous calls across domains. Since data is being transported across domains, users will be introduced to the concept of JSON with padding, called JSONP.
⦁ Chapter 5, Debugging JSON, explains the powerful tools that are available to debug, validate, and format JSON.
⦁ Chapter 6, Building the Carousel Application, implements the idea of a Carousel application and the required setup and dependencies, such as the jQuery library and the jQuery Cycle plugin, for the application. It uses Bootstrap to maintain a basic design for the application.
⦁ Chapter 7, Alternate Implementations of JSON, discusses the non web- development implementation of JSON, such as dependency managers, metadata stores, and configuration stores.
⦁ Chapter 8, Introduction to Hapi.js, talks about implementing JSON-based configuration in a Hapi server and creating RESTful APIs with the help of the same.
⦁ Chapter 9, Storing JSON Documents in MongoDB, begins by introducing MongoDB and then, explains how JSON is used in mongoDB. Next, it reaches the central theme of performing different operations on mongoDB JSON documents.
⦁ Chapter 10, Configuring the Task Runner Using JSON, outlines the gulp.js library. Gulp is a powerful library that manages and provides tools to create tasks.
⦁ Chapter 11, JSON for Real-Time and Distributed Data, familiarizes you with the usage of JSON data for real-time web applications by implementing the socket.io server and, furthermore, with Apache Kafka.
⦁ Chapter 12, Case Studies in JSON, is a case study on how JSON is enhanced for different domains, taking into consideration the various benefits it provided after implantation.
