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.

Testing the APIs using POSTMAN


The API endpoint we created (http://localhost:3300/greetings) is a GET method request type API call and it is quite easy to test the API endpoint directly in the browser URL locator. This is because when you hit any URL input from the browser URL locator directly, by default it performs a GET method request. So what about the POST, PUT, or DELETE request methods? Definitely, the browser is able to make those requests but not by default or through any direct input in the URL locator but by using AJAX requests or FORM POST requests.

In such cases, if we have created an API server and now we want to test our URL endpoint for sanity with respect to other request methods, we can't do it directly. Either we need to write some JavaScript code at the client side to make those API calls or use a REST client such as POSTMAN that can make API calls for us.
