Hello, Blazor enthusiasts!
Today, let’s explore the elegance of decoupling UI and logic in Blazor through a simple yet insightful example: a speed converter.

The Project at a Glance

Our project is a straightforward web application that converts speed from kilometers per hour (Km/h) to knots. It’s crafted using Blazor, a framework that allows us to build interactive web UIs using C#.

Decoupling in Action

  • The UI (Razor Page): Our front-end is designed in a .razor file. It’s sleek and user-focused, featuring an input field for Km/h, a conversion button, and an area to display the result in knots. We’ve used data-binding to connect UI elements with back-end properties.

  • The Logic (Code-Behind): The brains of our operation reside in a Converter.razor.cs file.
    This C# class, inheriting from ComponentBase, houses the properties for Km/h and knots, and most importantly, the conversion logic. When a user clicks the convert button, our logic jumps into action, transforming Km/h into knots.

Benefits of This Approach

  • Cleaner Code: By keeping our UI and logic separate, we ensure our code is tidy and more manageable.
  • Enhanced Maintainability: This separation simplifies future modifications and debugging.
  • Ease of Testing: Testing the logic independently from the UI becomes a breeze.
  • Scalability: This structure allows for easily scaling and reusing the logic across the application.

Conclusion

This example is a testament to how decoupling can streamline Blazor application development. It’s not just about following best practices; it’s about creating a codebase that’s robust, easy to manage, and a pleasure to work with.

Happy coding, and stay tuned for more Blazor tips and tricks!
