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.

JSON-based schemas in MongoDB


There is a possibility that we may need the database's schema before the application development gets started. Or what if we want to set the data types for all the datasets with all kind of validations just like MySQL?

At this point, we are planning to structure and validate our NoSQL data. We are moving toward finding a framework that provides a wrapper around mongodb and which can yield such features with trusted community support.

Mongoose is a leading third-party framework that provides all kind of schema-based validations, virtual properties, and more.

Let us go through an approach for how JSON-based schemas are prepared and validated using mongoose:

  1. Install mongoose via the following npm command: npm install mongoose --save
  2. As we are planning to implement mongoose in our application, we are going to use the wrapper methods provided by mongoose to connect to mongoDB

Not a big modification, simply comment the mongodb client from plugins.js and include the following...
