The MVVM Pattern in .NET MAUI

By: Pieter Nijs

Overview of this book

In today's fast-paced world of modern software development, teams need to be efficient, productive, and capable of rapidly adapting to changes to deliver high-quality products, making it crucial for developers to write maintainable and easy-to-test code. The MVVM Pattern in .NET MAUI helps you to thoroughly explore the Model-View-View Model (MVVM) design pattern. The chapters show you how this pattern helps in structuring code to embrace the separation of concerns, allowing for loosely coupled user interface and application logic, which ultimately empowers you to write more robust, maintainable, and testable code. The book also highlights .NET MAUI's capabilities and features, and enables you to delve into the essential components within the framework that facilitate the application of the MVVM pattern. With the help of a sample application, this definitive guide takes a hands-on approach to walk you through both the essential and advanced usages of the MVVM pattern to ensure that you successfully apply the practical aspects of the pattern to your .NET MAUI projects. By the end of this book, you’ll have gained a comprehensive understanding of the MVVM design pattern and its relevance in the context of .NET MAUI, as well as developed the skills needed to successfully apply it in practice.

Summary

We kicked off this chapter by revisiting the architecture of our Recipes! app to include repositories. This addition was aimed at adhering to the principle of SoC and minimizing our app’s dependency on the API itself. We also introduced the Result object, a transformative component in our error-handling strategy. This single object encapsulates both success and failure states, making our ViewModels more robust and intelligible. By using the Result object, we’ve made it easier to handle anticipated errors in a graceful manner, while still keeping exceptions reserved for critical failures.

After setting this architectural foundation, we moved on to explore the power and simplicity of Refit, a type-safe REST client. Refit has substantially streamlined the way we interact with APIs, making the code more readable and maintainable.

We also looked at how the Result object elegantly fits into our ViewModels, making it far easier to handle expected errors and providing...
