Build Tomorrow’s Best Mobile/Web Applications with IBM WebSphere Application Server 8.5 and IBM Worklight

This guide presents a coherent strategy for building modern mobile/web applications that are fast, responsive, interactive, reusable, maintainable, extensible, and a pleasure to use. Four IBM experts offer practical, hands-on coverage of front-end development with IBM WebSphere Application Server 8.5, IBM Worklight, and today’s most popular open source frameworks.

Using well-crafted examples, the authors introduce best practices for MobileFirst development, helping you create apps that work superbly on mobile devices and add features on conventional browsers. Throughout, you’ll learn better ways to deliver Web 2.0 apps with HTML /JavaScript front ends, RESTful Web Services, and persistent data. Proven by IBM and its customers, the approach covered in this book leads to more successful mobile/web applications—and more effective development teams.

Coverage Includes
• Developing for MobileFirst: moving from “graceful degradation” to “progressive enhancement”
• Quickly delivering lightweight JEE apps with WebSphere Application Server’s new Liberty Profile
• Implementing an agile, user-centered, page-oriented approach to design
• Constructing REST services with WebSphere Liberty, Eclipse, and JEE annotations
• Building better front-end application architectures with frameworks and JavaScript
• Designing and building complex, transactional RESTful services that interface with databases and other data sources
• Building IBM Worklight hybrid apps with open source frameworks: jQuery Mobile, Backbone, Require.js, and Handlebars
• Debugging cross-platform, multi-language modern web apps
• Promoting scalability, security, and connectivity into the wider enterprise
