Web development has become one of the most popular and in-demand forms of programming. Every day, more and more companies are faced with the need to create their own internet resources, ranging from simple websites to complex web applications. And today, we will discuss one of the most promising technologies for web application development - Blazor.
Blazor is a framework for creating interactive web applications using the C# programming language. It is based on the WebAssembly technology, which allows executing code in languages other than JavaScript, such as C# or Rust, in the user's browser.
Blazor includes two development models: Blazor Server and Blazor WebAssembly. Blazor Server is a model where the application logic is executed on the server and only the data is updated in the browser. Blazor WebAssembly is a model where the entire application is loaded and executed in the browser.
Let's take a closer look at each of these models.
Blazor Server:
Blazor Server is a model that allows rendering the interface using C# based components. However, all actions and events are handled on the server, and only the updated data is sent back to the client-side of the application. This means that users can interact with the application without waiting for it to launch and without loading all its components.
Blazor Server has a low entry barrier and supports all the advantages of the C# language. But there are also some disadvantages. First of all, the application works in a client-server mode, so the dependency on the network connection is critical. Secondly, all processing actions occur on the server, so a poor connection or a large number of users can lead to significant delays and negative user experience.
Blazor WebAssembly:
Blazor WebAssembly is a model where all the code is executed in the user's browser. As mentioned before, it uses WebAssembly technology to execute C# code. This means that when developing with Blazor WebAssembly, you can use all the advantages of the C# language, including type safety, asynchronous programming, and multithreading.
Blazor WebAssembly has several advantages. Firstly, the application is fully executed on the client side, which significantly reduces the server load and provides better performance for end users. Secondly, since the application is executed in the browser, it can be run on almost any device and platform without the need for installation and updates.
However, Blazor WebAssembly also has some drawbacks. Firstly, websites developed with Blazor WebAssembly require compatibility with a browser that supports WebAssembly technology. Although most modern browsers support WebAssembly, some older versions may not, which can limit the potential user base.
Blazor is a powerful tool for web application development. It allows you to use the advantages of the C# language to create interactive interfaces, regardless of the project's complexity. Thanks to the two development models - Blazor Server and Blazor WebAssembly - developers can choose the most suitable model for their needs and requirements, based on resource availability, performance requirements, and user limitations.
