Overview of this book

Organizations are moving their applications, data, and processes to the cloud to reduce application costs, effort, and maintenance. However, adopting new technology poses challenges for developers, solutions architects, and designers due to a lack of knowledge and appropriate practical training resources. This book helps you get to grips with Oracle Visual Builder (VB) and enables you to quickly develop web and mobile applications and deploy them to production without hassle. This book will provide you with a solid understanding of VB so that you can adopt it at a faster pace and start building applications right away. After working with real-time examples to learn about VB, you'll discover how to design, develop, and deploy web and mobile applications quickly. You'll cover all the VB components in-depth, including web and mobile application development, business objects, and service connections. In order to use all these components, you'll also explore best practices, security, and recommendations, which are well explained within the chapters. Finally, this book will help you gain the knowledge you need to enhance the performance of an application before deploying it to production. By the end of this book, you will be able to work independently and deploy your VB applications efficiently and with confidence.

Exploring life cycle events

Each and every page in a VB application goes through a life cycle in which a series of actions or tasks is performed. These actions include the initialization of a page, the initialization of types and variables, the rendering of UI components, allowing a user to save the changes before they exit a page, and the cleanup of the resources after leaving the page. It's really important to understand the life cycle of a page so that you can write your code at the correct life cycle stage.

Similarly, an application and its flows have their own life cycles. An application can contain multiple flows, and a flow can contain multiple pages.

Every stage of the page has associated events that you can use to write your code. For example, you want users to log in before they try to access a secured page, and you want to delete the user's session after they have left that page.

Let's learn about the different life cycle events of a page through...
