In recent years, web application development has been constantly evolving, with a focus on finding more efficient and powerful solutions. One of the latest additions to this dynamic environment is Blazor, a framework from Microsoft that allows developers to create interactive web user interfaces (UI) using C# instead of traditional JavaScript. This article focuses on the key aspects of Blazor, its architecture, benefits, and a comparison with existing solutions.

What is Blazor?

Blazor is an open-source framework that is part of ASP.NET, enabling developers to build dynamic web applications using C# and .NET on the client side. This allows code sharing between the server and client without the need for JavaScript. Blazor offers two hosting models: Blazor Server and Blazor WebAssembly.

Blazor Server vs. Blazor WebAssembly

Blazor Server works by running all application logic on the server, with UI changes transmitted over SignalR, a library for real-time communication. This solution is suitable for applications where the speed of initial loading is critical and offline functionality is not required.

Blazor WebAssembly, on the other hand, allows executing C# code directly in the user's browser using WebAssembly technology. This variant brings the advantage of offline functionality and reduces the server load but requires longer initial application loading times.

Benefits of Using Blazor

• Unified Language: Developers can use C# across the entire application, eliminating the need to learn and maintain code in different languages.
• Code Sharing: The ability to share application logic between frontend and backend reduces code duplication and simplifies maintenance.
• Modern Web Standards: Blazor leverages modern web standards like WebAssembly, enabling the creation of high-performance applications directly in the browser.
• Integration with .NET Ecosystem: Access to a wide range of libraries and tools in the .NET ecosystem increases development productivity.

Comparison with JavaScript Frameworks

While JavaScript frameworks such as React, Angular, and Vue dominate web application development, Blazor offers an intriguing alternative for developers familiar with C# and the .NET ecosystem. The main difference lies in the ability to leverage existing .NET libraries and tools, which can significantly accelerate the development process in some cases.

Blazor represents a significant step forward for developers who prefer C# and the .NET ecosystem when building web applications. It offers flexible hosting options, integration with modern web technologies, and, most importantly, enables more efficient development through code sharing and the use of existing .NET libraries. Like any technology, Blazor has its advantages and limitations, but its potential for developing modern, interactive web applications is undeniable.
