It is important to understand that both synchronous and asynchronous calls are made over HTTP, so the data transfer process is the same. The most popular methods of transferring data from the client machine to the server machine are GET and POST. The most common request method in HTTP is GET. When a client requests a web page, the web server uses the URL to process the HTTP request. Any other parameters that are appended to the URL serve as the data that is being sent from the client to the server. Since the parameters are part of the URL, it is important to make a clear distinction between when and when not to use the GET request method. The GET method should be used to pass idempotent information such as a page number, a link address, or the limits and offsets that are a part of pagination. Keep in mind that there is a size constraint...

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.
