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.

Building the JSON file for the Carousel application


Let's assume that we are an educational institution, and we have a tradition of acknowledging the efforts of our students on a monthly basis. We will pick the top students from each course for that month, and display their names on our notice board rotator application. This notice board rotator application has often served as a motivation for other students, who always aim to get themselves onto that board. This is the way our educational institution encourages the students to do well in their courses. The example JSON feed will look as follows:

For our notice board rotator application, we will need basic student information, such as the first name, last name, current level of education, and the course that they have excelled in:

    })
})
</script>
