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.

BSON – a fast-traversal JSON format


We have already learned about BSON implementation in MongoDB. In fact, MongoDB was the first one to leverage BSON fully. We won't learn about other implementations for now, as they are beyond the scope of this book. Interested readers can visit this link for more information: http://bsonspec.org/implementations.html.

As JSON data is converted to binary, there is increase in the speed of traversal of BSON data. BSON extends the JSON data type collection by providing more data type support with respect to binData and Date type. These advantages make BSON capable of using it as a record for any unstructured database design.

If the BSON format is used for data passing over network, as the data is binary, the encoding and decoding of data among different network devices is simpler and can be done at quicker speeds.

BSON is storage efficient—still, it may be slightly bigger in size when compared to serialized JSON. This is because BSON data has more properties...
