An Introduction to Blazor Application Development

Blog Images

Blazor is developed by Microsoft in 2018. Blazor is an open-source and free web framework that allows developers to create web applications using C# and HTML. Blazor is a new framework by the Microsoft ASP.NET team that introduces a next-generation component model that allows developers to write single-page applications (SPA) without using JavaScript. Blazor is the best framework for building interactive client-side web UI with .NET. Blazor apps are based on some components. It uses natural HTML tags for UI composition.

More C# less JavaScript

Nowadays, when we are deciding to develop a data-driven web application. Importantly we need two things.

  1. Server-side Development
  2. Client-side Development

Server-side Development: In server-side development we use programming languages such as C#, Java, PHP etc.

Client-side Development: In client-side development we generally use JavaScript frameworks such as Angular, React, etc. If we are trying to become a full-stack developer, we have to learn client-side programming language as well as server-side programming languages.

Can We Use C# in Both Client-side and Server-side Development?

Yes, it is possible because of ASP.NET Core Blazor. By using Blazor, you can develop client-side web user interfaces using C# instead of JavaScript.

What is Blazor?

Blazor (Browser + Razor) is a relatively young technology. It's main attraction is people can use their language C# to make single-page applications. Blazor is more future choice and it is best suited to Microsoft developer who loves .NET and C#.

Blazor Server

Blazor Server provides support for hosting Razor components on the server in an ASP.NET core app. The connection communicate with the browser is also used to handle JavaScript Interop calls. Blazor application is executed on the blazor server in ASP.NET core app. We can use the blazor server app, to create applications with the server hosting model.

Blazor WebAssembly (WASM)

Blazor WebAssembly is released in May 2020. It work as a single-page application framework for building interactive client side web applications with .NET. WebAssembly uses open web standards beyond using of plugins or recompiling code into other languages. It works in all present web browsers including mobile browsers.

Running .NET code inside web browser is made possible by WebAssembly.

WebAssembly code can access the full functionality of the browser via JavaScript called JavaScript Interoperability.

Features of Blazor

  • Best component model for building UI
  • Rich tool and IntelliSense
  • Validations and forms
  • During development, there will be live reloading in the browser
  • Routing and forms
  • Rendering in server-side
  • It enhances the productivity of developers
  • Uses the latest web development features
  • The use of C#
  • Debugging using ASP.NET
  • It has JavaScript Interoperability, so the developer can use ASP.NET

Comparing Blazor VS JavaScript Framework

Blazor works on Web Assembly and C#. Angular, Vue.js and React are JavaScript frameworks. Blazor uses incremental DOM and JavaScript uses the virtual DOM. Now we can compare JavaScript frameworks with Blazor.

React Vs Blazor

Blazor is a new open-source web framework while react has been around a time. With both the server-side and client-side are written in C#, so we can share libraries and codes. Blazor gives us a platform for the development of single-page applications when using .NET. Blazor has two versions :

  • Blazor Server
  • Blazor WebAssembly

React is developed by Facebook in 2013. React is a very efficient and flexible JavaScript framework. It will help with building UI components Blazor & React are the same as being client-side applications. React is using JavaScript programming language. And whenever you are using this framework, the developers can write the language they are familiar with. Using React developers can develop iOS, Android, and web applications. JSX is used by React so it helps for the construction of machine-readable codes.

Angular Vs Blazor

Angular is also a JavaScript framework developed by Google in 2016. This framework aims to develop & test single-page applications. Blazor & Angular are open-source frameworks. Angular is production-ready but Blazor is still developing. Blazor can’t work as a PWA but Angular has support for PWA. Razor only supports VS code language server but the tooling is mature in Angular.

Future of Blazor

In this article, you learned about Blazor and its features. Blazor provides a unique platform for all kinds of applications which makes it easy for all developers. It is a new and exciting model for programming. Some structure is perfect for the Blazor server.

 Also, Blazor has its limitations. Blazor has the benefit of not having to reload the page every time a link click performed. Blazor is fast and reuse existing libraries and can run our application in any browser.

It makes web development easier and productive by providing full-stack web development. Blazor embraces the building of web applications that gradually becoming more abstracted from HTML. It is best suited to Microsoft developers who love .NET and C#. The latest version of Blazor is .NET 6.

.NET 6

It was released on November 8, 2022. It is supported on macOS, Apple, Silicon and multiple operating systems. In .NET 6 memory single file applications has been enabled for Windows and macOS. In Blazor .NET 5 this type was limited to Linux.

Features in .NET 6

  • .NET 6 is faster than .NET 5
  • .NET 6 is supported for 3 years as the LTS release
  • Performance is improved
  • Improvements in visual basic
  • Improvement in cloud diagnostics
  • Single-page apps built with ASP.NET core now use a flexible pattern that is used with Angular, React, and other popular frontend JavaScript frameworks
  • Improved the security
  • Source generators and analyzers have been added so it helps you produce better, safe, and higher performance code
  • .NET 6 scores a 50% higher throughput than .NET 5
  • Memory cache performance improved
  • .NET 6 in memory single file app has been enabled for Windows and macOS. In .NET 5 this deployment type was limited to Linux
