What is Blazor (An Overview)
In this article, I am going to discuss What is Blazor. Microsoft has recently released a new .NET web framework called Blazor. It is a free, open source Web framework to build Web apps using C# that run in a Web browser. As part of this article, I am going to discuss the following pointers in detail.
- How we develop web applications today?
- What is Blazor?
- Why should we use it?
- Understanding WebAssembly
- What are the advantages of using Blazor?
How we develop web applications today?
In order to develop web application we need two things. Server side development and client side development.
In order to become a full stack software developer and to stay in the market, you need to learn a client-side programming language (Angular, React, Vue, etc.) as well as a server-side programming language (C#, Java, PHP, etc.).
Now the question is, why should we learn 2 different sets of programming languages and frameworks.
Can we use C# both for server-side and client-side development?
Now, the question that should comes to your mind is, how a browser execute the C# code.
How can a browser execute C# code?
What is WebAssembly?
The WebAssembly is a low-level assembly-like language in binary format that can run in the modern web browser.
ASP.NET Core Blazor Hosting Models
The Blazor offers 2 hosting models. Blazor WebAssembly and Blazor Server.
This is also called as the client-side hosting model and in this hosting model, the blazor application going to be run directly in the browser. So, everything the application needs i.e the compilation of application code, it’s dependencies and the .NET runtime are downloaded to the browser. In our upcoming articles, we will discuss more about Blazor WebAssembly.
This is also called as the server hosting model and in this hosting model, the application is executed on the server from within an ASP.NET Core application. Between the client and the server, a SignalR connection is established. When an event occurs on the client such as a button click, the information about the event is sent to the server over the SignalR connection.
The server handles the event and for the generated HTML a diff (difference) is calculated. The entire HTML is not sent back again to the client, it’s only the difference that is sent to the client over the established SignalR connection. The browser then updates the UI. It embraces the single page application architecture which rewrites the same page dynamically in response to the user action. Since only the diff is applied to update the UI, the application feels faster and more responsive to the user. In our upcoming articles, we will discuss more about Blazor Server.
The ASP.NET Blazor makes the web development more easier and more productive by providing a full stack web development with .NET Framework. Following are the advantages of using Blazor.
- .NET offers a range of API and tools across all platform that are stable and easy to use.
- The modern languages such as C# and F# offer a lot of features that make programming easier and interesting for developers.
- The availability of one of the best IDE in form of Visual Studio provides a great .NET development experience across multiple platforms such as Windows, Linux, and MacOS.
- .NET provides features such as speed, performance, security, scalability, and reliability in web development that makes full stack development easier.
- Blazor also supports features of a SPA (Single Page Application) framework such as:
- Dependency Injection
- Forms and validation
- Server-side rendering
In the next article, I am going to discuss the Environment Setup for Blazor App Development. Here, in this article, I try to give an overview of Blazor. I hope you enjoy this article.
