Data feeds are often large amounts of data that are made available; the data that is part of such feeds is normally generic and can be considered too heavy for a targeted search. For example, in the students JSON feed, we are exposing the whole list of student information that is available. For a data vendor who is looking for students who are enrolled in certain courses or who reside in a given ZIP code to hire them as interns, this feed is going to be generic. It is common to see development teams build Application Programming Interfaces (APIs), to give such data vendors numerous ways to target their search. This is a win-win situation for both the data vendor and for the company that owns the information, since the data vendor only gets the information that they are looking for and the data supplier only sends the requested data, thereby saving a lot of bandwidth...

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.
