This book was released on 2017-07-27 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: Build powerful cross-platform desktop applications with web technologies such as Node, NW.JS, Electron, and React About This Book Build different cross-platform HTML5 desktop applications right from planning, designing, and deployment to enhancement, testing, and delivery Forget the pain of cross-platform compatibility and build efficient apps that can be easily deployed on different platforms. Build simple to advanced HTML5 desktop apps, by integrating them with other popular frameworks and libraries such as Electron, Node.JS, Nw.js, React, Redux, and TypeScript Who This Book Is For This book has been written for developers interested in creating desktop applications with HTML5. The first part requires essential web-master skills (HTML, CSS, and JavaScript). The second demands minimal experience with React. And finally for the third it would be helpful to have a basic knowledge of React, Redux, and TypeScript. What You Will Learn Plan, design, and develop different cross-platform desktop apps Application architecture with React and local state Application architecture with React and Redux store Code design with TypeScript interfaces and specialized types CSS and component libraries such as Photonkit, Material UI, and React MDL HTML5 APIs such as desktop notifications, WebSockets, WebRTC, and others Desktop environment integration APIs of NW.js and Electron Package and distribute for NW.JS and Electron In Detail Building and maintaining cross-platform desktop applications with native languages isn't a trivial task. Since it's hard to simulate on a foreign platform, packaging and distribution can be quite platform-specific and testing cross-platform apps is pretty complicated.In such scenarios, web technologies such as HTML5 and JavaScript can be your lifesaver. HTML5 desktop applications can be distributed across different platforms (Window, MacOS, and Linux) without any modifications to the code. The book starts with a walk-through on building a simple file explorer from scratch powered by NW.JS. So you will practice the most exciting features of bleeding edge CSS and JavaScript. In addition you will learn to use the desktop environment integration API, source code protection, packaging, and auto-updating with NW.JS. As the second application you will build a chat-system example implemented with Electron and React. While developing the chat app, you will get Photonkit. Next, you will create a screen capturer with NW.JS, React, and Redux. Finally, you will examine an RSS-reader built with TypeScript, React, Redux, and Electron. Generic UI components will be reused from the React MDL library. By the end of the book, you will have built four desktop apps. You will have covered everything from planning, designing, and development to the enhancement, testing, and delivery of these apps. Style and approach Filled with real world examples, this book teaches you to build cross-platform desktop apps right from scratch using a step-by-step approach.

Download or read book Learning Modular Java Programming written by Tejaswini Mandar Jog and published by Packt Publishing Ltd. This book was released on 2016-06-30 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explore the power of modular programming for building applications with Java and Spring! About This Book Understand the basic concepts of Modular Programming to build enterprise applications with Java Create short and precise code and eliminate recursion The book follows a step-by-step approach that makes implementing Modular Programming easy Who This Book Is For This book targets Java developers who have a basic knowledge of application development with Java and are interested in learning the Modular Programming approach for building reusable applications that are easy to test, and thus improve overall project management. What You Will Learn Learn about Modular Programming and what modules an enterprise application can be divided into. Set up a development environment and create a "Hello World" application. Start implementing a sample application from the presentation layer. Implement the persistence layer. Implement the business layer, wrapping up all of the modules with Contexts and Dependency Injection (CDI). Manage an application's life cycle. Learn how to secure Web applications. Test enterprise applications and their automation. Understand how to version source code using Source Code Management (SCM) systems such as GIT and SVN. In Detail Modular programming means dividing an application into small parts and then developing it. It is an approach taken by developers to build applications and helps them add efficiency in their development process, thus making it more effective. The book starts with the fundamentals of Modular Programming. Then we move on to the actual implementation, where we teach developers how to divide an application into different modules or layers (such as presentation, execution, security, lifecycle, services, and so on) for better management. Once readers are well-versed in these modules and their development, the book shows how to create bindings in order to join these different modules and form a complete application. Next, the readers will learn how to manage these modules through dependency injection. Later, we move on to testing; readers will learn how to test the different modules of an application. The book ends by teaching readers how to maintain different versions of their application and how to modify it. By the end of the book, readers will have a good understanding of modular programming and will be able to use it to build applications with Java. Style and approach This book is a practical guide to help readers learn Modular Programming with Java and build an enterprise-ready app along the way. The book is divided into three major sections. The first teaches the fundamentals of Modular Programming and how to implement them; the second teaches readers to combine and manage the modules developed; in the final section, the book explains the applications of Modular Programming.
