Frontend Dev: Blazor VS JavaScript

Blazor came up in the rankings within a short period. People have started to compare it with popular javascript frameworks. There are many discussions about the future of client-side web development, and those discussions and comparisons have made it even popular. So, let’s see what makes Blazor so unique.

As I have mentioned at the beginning, the main plus point of Blazor is that it enables us to develop and execute browser-based applications using C#. For the past several years, JavaScript (or TypeScript) has been the primary programing language used to create the frontend. If you are a .NET developer, you had to learn JavaScript, in addition, to become a full-stack web developer. With Blazor, you can develop both server and client sides using C#. For me, persoanally, that is the primary advantage when it comes to Blazor.

Unlike JavaScript, Blazor is pre-compiled into intermediary language. This feature gives us some remarkable benefits when it comes to performance demanding applications that run on the browser. Plus, Blazor applications can work offline for times where more processing power is needed, such as PDF generation, Gaming algorithms &, etc.

Apart from those, there are many features/advantages of Blazor:

  • Blazer doesn’t require browser plugins.
  • Enables Full .NET debugging.
  • It uses the latest web browser capabilities.
  • Model for building compassable UI.
  • Browser compatibility (even for older versions).
  • Dependency injection is available.
  • Can share code between client and server.

Here comes the most crucial part of the article. Will Blazor take over JavaScript? Can Javascript hold its position? These are the questions that everyone is seeking for answers. I think, it is too early to make any direct predictions or conclusions on those questions. But we can compare a few leading JavaScript frameworks with Blazor to see their differences.

Blazor vs. React

Many find React as the best library for web component development. Though its difficult to compare the two, we have to agree that React is well-established and earned its respect with a proven track record and by having a strong community around it.

React’s eco-system is booming with libraries and frameworks that streamline the development of optimized React apps. Among these tools and libraries are, what I consider, real deal-brakers like () that help in managing and sharing React components.

Libraries that make React a “universal language”, capable of delivering apps for the web, , , , and more, coupled with component sharing tools, like , make React too hard to pass.

React components shared on to be used in multiple apps

In comparison, Blazor is new but, it brings the flavor from its well-established counterpart Razor. So we don’t need to consider it entirely novel to developers. Besides, since Blazor uses C# for development, the transition for any .NET developer would be faster. Although React brings a large variety of features and advantages with its maturity, we can also notice several advanced features available with Blazor regardless of its’ age.

  • Similar to React, we can deploy Blazor also as static files.
  • Can use NuGet packages.
  • We can use the same components, both the client & server-side (though that is, of course, also possible when using JS/TS)
  • Blazor has built-in support for routing, validations, and form handling.

These are only a subset of features Blazor provides. But, based on the current situation, sticking with React will be the best option if your development team is good with JavaScript. On the other hand, Blazor is an excellent option to consider if you are firm with .NET than JavaScript and starting with a new project.

Blazor vs. Angular

Angular is another JavaScript framework popular for single-page applications. In comparison to React, its more of a complete framework than a library. Angular provides client-side MVC architecture to simplify the development and testing process. When it comes to comparison between Angular and Blazor, Angular remains in the front seat since it is well known, stable, and production-ready. Besides, Angular fully supports PWA while Blazor’s server-side is yet to become compatible. Moreover, since Angular uses TypeScript, it is more relatable and understandable for C# developers than JavaScript. With Angular holding all the cards, I can’t see any groundbreaking features of Blazor, which will make someone who is good at TypeScript to turn into Blazor.
