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.

Debugging the application code

In this section, we'll look at how to debug the application code step by step to identify the issues raised during development and runtime. VB uses Verbose mode, which captures the complete details of what's happening inside the application. Verbose mode shows additional information as to what an application is doing. The developer only has to rely on the browser development tools to track the end-to-end flow.

When you run the application, the complete flow of the application is captured in the browser console, including the REST calls, variables assignment, Action Chain flow, events, and so on. Everything is logged in the sequence from the starting of the application until the page loading successfully.

The following screenshot shows the browser developer console that shows all the actions that are captured when the + Add button is clicked:
