Summary
Preface
In real-world enterprise application design and development, multiple aspects need to be considered, starting from building a simple drop-down list to developing platform-independent features such as accessibility or UI consistency, which are left unattended more often than not. Oracle JavaScript Extension Toolkit (JET) gives you the set of important building blocks needed for your application, and it doesn't forget about making your application mature, in terms of internationalization, localization, and multiplatform development.
While we describe each of the concepts with a detailed explanation and handy diagrams that aptly represent the components and developer actions, we also bring appropriate examples and code snippets to help you understand how they can be implemented with the help of Oracle JET.
There are numerous improvements to the Oracle JET concepts and additional features that enable support for the development of web applications with Oracle JET. We'll discuss each of the Oracle JET concepts, along with improvements and their implementation in, separate chapters; these concepts have helped the field of web development advance further over the last few decades. This should cover the design thoughts and security aspects as well, which we believe lets you concentrate on each specific topic and understand it a step further with the right combination of explanations, diagrams, and code snippets.
This book took about 6 months for me to write and it was a great journey. The design and development experiences with multiple enterprise applications on cloud portfolio and webpack systems, along with the support of solution architecture teams, helped me go through the on-ground challenges and improve the design standpoint of the web interface. There are many places where I start talking about the project development life cycle, Agile, TDD and BDD, and the importance of rapid development and automated tests on UI development before the solution implementation specifics. Also, care has been taken to help you with the explanation of the concepts in such a way that you'll feel like you're participating in a detailed technical conversation.
Most of the concepts are imbued with an everlasting perception of reusability and thorough engineering, and I believe some parts of this will remain with you as useful techniques to reuse in your application development.
Finally, while I've made sure to complement every chapter with plenty of illustrations to get the desired output, I think it is paramount for you to review each concept and practice it, so you learn and build your confidence of working with such systems.
Have fun building great things!
What this book covers
Chapter 1, Getting Started with Oracle JET, gets you started with using Oracle JET, bootstrapping the project, and understanding the project's base architecture.
Chapter 2, Oracle Alta UI, explores the different ways of using the UI framework, Alta, in Oracle JET.
Chapter 3, Tools Integration, explains how to integrate Oracle JET into your build pipeline. The most popular build tools are covered in this chapter.
Chapter 4, Knockout JS, introduces and explores Knockout, the library behind OJ. It also covers best practices around it.
Chapter 5, Oracle JET Components – Form Elements, Controls, and Data Collections, covers the handling of components related to collections, controls, and forms.
Chapter 6, Oracle JET Components – Layouts, Navigation, and Visualizations, discusses the components related to layouts, navigation, and graph visualizations.
Chapter 7, Framework, explains the application part of an OJ project. The chapter is divided into two subsections covering a wide spectrum of concepts, from component validations to routing and tests.
Chapter 8, Hybrid Mobile Application Development explains how a multiplatform application can be set up and developed.
Chapter 9, Testing and Debugging, explores the testing and debugging of Oracle JET applications.
Chapter 10, Security and Version Migration, examines different security issues and constraints associated with web applications, what to look for when the version changes, and what's to come in the next Oracle JET versions.
What you need for this book
To follow along with this book, you'll need a computer with an internet connection. You can choose to work online on a JSFiddle kind of cloud web environment to practice the examples. I recommend that you have the NetBeans IDE with Grunt, Oracle JET, and the HTML5 extension along with a Chrome browser containing the NetBeans runner.
Who this book is for
This book has been tested on people who have a decent programming knowledge of web applications with basic HTML, CSS, and JavaScript, and who wanted to venture into learning a framework that will help them build features on top of the base components. They picked up with practice and by the end of the book, they gained a thorough knowledge of Oracle JET and its design aspects. Through this book, you will learn some tricks and tips that you didn’t know about and be given wise suggestions that will help you along the way.
This book, if followed from cover to cover, will turn you into a proficient web interface expert. On the other hand, if you already are, it provides a good reference for many different features and techniques that may come in handy from time to time. Finally, this book is also a valid migration guide if you have already experimented with Oracle JET concepts and felt overwhelmed by the change.
Conventions
In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning. Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "Similarly, we have added another markedEmployee."
A block of code is set as follows:
<td data-bind='text: name'></td>
Any command-line input or output is written as follows:
npm -g install yo grunt-cli
New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Click on the Install button, which should install Node.js, along with the npm package manager, on your computer."
