Until recently, creating desktop-like applications in the browser meant using inefficient Ajax or Comet technologies to communicate with the server. With this practical guide, you'll learn how to use WebSocket, a protocol that enables the client and server to communicate with each other on a single connection simultaneously. No more asynchronous communication or long polling! For developers with a good grasp of JavaScript (and perhaps Node.js), author Andrew Lombardi provides useful hands-on examples throughout the book to help you get up to speed with the WebSocket API. You'll also learn how to use WebSocket with Transport Layer Security (TLS). Learn how to use WebSocket API events, messages, attributes, and methods within your client application Build bi-directional chat applications on the client and server with WebSocket as the communication layer Create a subprotocol over WebSocket for STOMP 1.0, the Simple Text Oriented Messaging Protocol Use options for older browsers that don't natively support WebSocket Protect your WebSocket application against various attack vectors with TLS and other tools Debug applications by learning aspects of the WebSocket lifecycle

This book will teach you how to use the Spring Framework to build Java-based applications, web applications, and microservices. Aimed at beginners, it has been revised and expanded to reflect the latest features and best practices for Spring 6. Authors Joseph Ottinger and Andrew Lombardi will get you started using Spring Framework 6 and its ecosystem, walking you through all the best practices in modern application development. You’ll see how Spring has drastically and positively affected the way applications are designed and programmed in Java, and how to build apps with the Spring mindset. Along the way, you will learn many aspects of the Spring ecosystem with easy-to-understand applications designed to teach you not only the technology, but also the practices that benefit the most from Spring. Starting with the basics, you’ll learn gradually, including topics such as the configuration and declaration of beans, the application lifecycle, how todeploy a Spring application into a Java EE application, Spring Reactive, Spring Web, Spring Boot, and Spring Cloud. After completing this book, you’ll be prepared to develop your own scalable, modular Spring-based applications. What You Will LearnDiscover the most common use cases encountered in the real worldLearn the proper way of testing with the Spring frameworkCreate reliable, modular softwareBuild skills that will translate well across all languages and environmentsIntegrate and use data access and persistence frameworks such as Hibernate, JPA, and MongoDBGet started with the most common, most-used Spring features Who This Book Is ForThose who are new to Spring or for those who have experience with Spring but want to learn what's new in Spring 6. This book assumes you have some prior coding experience inJava, but many core concepts in Java are discussed as they’re encountered.
