Delphi Programming Projects

▶Book Description
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.

▶What You Will Learn
- Get to grips with the advanced features of RTL
- Understand how to deal with the paradigm change between multiplatform projects
- Build rich interfaces with Google's Material Design features
- Understand how to implement design patterns in Delphi
- Turn a mobile device into a remote controller with app tethering technology
- Build a multi-database system using VCL

▶Key Features
- Build responsive user interfaces (UIs) for desktop and mobile with FireMonkey
- Implement a microservices architecture using the Rapid Application Development(RAD) server
- Create clones of popular applications like Instagram and Facebook using Delphi 10.3

▶Who This Book Is For
This book is for developers, programmers, and IT professionals who want to learn the best market practices by implementing practical projects. Prior knowledge of the Delphi language is a must.

▶What this book covers
- Chapter 1, Building an Instagram Clone, introduces the basics of layouts and responsiveness on Android and iOS platforms and also how to use SVG icons, camera features, permissions, and a mobile device's media library.

- Chapter 2, Building a Facebook REST API, deals with building an application that consumes the Facebook REST API using native REST components and working with JSON.

- Chapter 3, Cross-Platform Services for Windows, iOS, and Android, covers how service applications take requests from client applications, process those requests, and return information to client applications. It also covers how they typically run in the background, without much user input.

- Chapter 4, Design Patterns to Build a Multi-Database System, deals with design patterns such as singleton, repository, and others for creating multi-database applications and isolating business rules from forms.

- Chapter 5, Creating GUI Apps with FireMonkey, introduces the concepts of Material Design and simulates the use of Material Design using FireMonkey visual components.

- Chapter 6, Implementing Tethering to Create a Remote Control, introduces app-tethering technology, and how to turn a mobile device into a remote control for a computer (using Wi-Fi or Bluetooth connections).

- Chapter 7, Building Microservices Using the RAD Server, shows how to develop microservices architecture implement it in Delphi, and use a non-centralized architecture, where we can perform different functions on different platforms.
