Delphi Programming Projects

Overview of this book

Delphi is a cross-platform programming language and software development kit that supports rapid application development for Microsoft Windows, Apple Mac OS X, Android, and iOS. With the help of seven practical projects, this book will guide you through the best practices, Delphi Run-Time Library (RTL) resources, and design patterns. Whether you use the Visual Component Library (VCL) or FireMonkey (FMX) framework, these design patterns will be implemented in the same way in Delphi, using Object Pascal. In the first few chapters, you will explore advanced features that will help you build rich applications using the same code base for both mobile and desktop projects. In addition to this, you’ll learn how to implement microservice architecture in Delphi. As you get familiar with the various aspects of Delphi, you will no longer need to maintain source code for similar projects, program business rules on screens, or fill your forms with data access components. By the end of this book, you will have gained an understanding of the principles of clean code and become proficient in building robust and scalable applications in Delphi.

Summary

We have introduced through this mini Instagram clone how to work with basic responsive design, making sure that, regardless of the size of the screen, our controls adjust according to the screen. Then, through the TPath component, we included icons in SVG format, drastically reducing the size of the images and icons thanks to vectorization.

Our code was simple and consisted of only three lines. At a minimum, we can take a photo, choose a photo from the library, and share with friends. All this is done using ActionList and interfaces already done in the FireMonkey library.

In the next chapter, you'll be introduced to the wonderful world of APIs. Not only is it possible to consume Facebook API services, but you can develop your application on the platform by interacting with Delphi.

Delphi is this simple, RAD, and practical!
