Blazor: The Web Framework That Let’s You Break Up with JavaScript


Let’s face it: JavaScript and C# are like two exes that you just can’t quit. You need them both, but constantly bouncing between the two can leave you feeling a little...discombobulated. Enter Blazor, your ticket to full-stack development bliss—all in C# and .NET.

No more switching personalities between the browser (JavaScript) and the server (C#). With Blazor, it’s all C#, all the time. So, why should you get excited? Let me count the ways.

1. C# for Full-Stack Development: The Dream Team

Imagine being able to use your favorite language (yes, C#) to develop both the client and server side of your web app. No more learning JavaScript just to make a button do something fancy. Blazor lets you stay in your C# comfort zone, allowing you to share code between the client and server, reuse business logic, and bask in the glory of DRY (Don’t Repeat Yourself) principles.

Who needs to switch languages mid-project when you can have a unified codebase? This means fewer mental context switches and more time enjoying your coffee.

2. Component-Based Architecture: Tiny Lego Pieces for Your App

Ever played with Legos? Blazor's component-based architecture is like building your app with tiny, reusable blocks. Each component can encapsulate its own UI and behavior, and the best part? You can reuse these components across your app like a magician pulling endless rabbits out of a hat.

Plus, with two-way data binding, your components and data are always in sync. It’s like your app is doing its own dishes—automatically cleaning up data and UI without you lifting a finger.

3. All the .NET Goodies in One Place

Why reinvent the wheel when Blazor gives you access to the entire .NET ecosystem? You get to play with heavy hitters like Entity Framework for databases and SignalR for real-time magic. Blazor inherits all the maturity and performance of the .NET runtime, meaning you’re standing on the shoulders of giants.

And the tooling? Oh boy. Visual Studio’s deep integration makes development feel like you’re driving a luxury car—complete with IntelliSense, hot reload, and debugging so smooth you’ll feel like a coding wizard.

4. Goodbye JavaScript (Well, Mostly)

You know that feeling when you finally toss out something you don’t need anymore? With Blazor, you can throw JavaScript overboard—at least for most things. While Blazor does allow you to use JSInterop when you need it, for most core functionalities, you’re 100% in C# territory. JavaScript becomes a nice-to-have, not a must-have.

Need to work with an old JavaScript library? No problem! Blazor’s got your back with seamless interop, but you’ll never feel like you have to use it.

5. Choose Your Own Adventure: Blazor Server or WebAssembly?

Blazor doesn’t just stick to one way of doing things. You can pick between Blazor WebAssembly (WASM) and Blazor Server, depending on your needs:

  • Blazor WebAssembly lets you run C# directly in the browser using WebAssembly (no server round trips needed). Imagine your app being fast, offline-ready, and delivering near-native performance.
  • Blazor Server is perfect for when you need lightning-fast load times and real-time updates via SignalR.

Both models offer flexibility, so whether you want all the action in the browser or prefer to keep things server-side, you’ve got options.

6. Productivity Superpowers

With Blazor, your productivity goes through the roof. Forget spending hours Googling "how to do X in JavaScript," because everything is right there in Visual Studio, including live reload, which updates your app as you code. And Blazor’s Razor syntax is the icing on the cake: combining HTML and C# in one elegant file, making your code more readable than a comic book on a lazy Sunday.

7. Cross-Platform: Blazor Takes You Everywhere

Why stop at the web? Blazor’s cross-platform nature means you can take your app to mobile and desktop with .NET MAUI. So, with the same Blazor components, you can build an app that runs on iOS, Android, Windows, and macOS. One codebase, many platforms—sounds like the future, right?

8. Real-Time Magic with SignalR

Need real-time updates for a chat app or a dashboard? Blazor’s real-time capabilities with SignalR are the stuff of legends. You can push updates to the UI without refreshing the page, making your app feel snappy and dynamic. It's like waving a magic wand and having your UI instantly updated—poof, no reload required.

9. Rich, Interactive UI Without the JavaScript Bloat

Blazor’s clever rendering model means only the UI diffs (changes) are sent to the client. This keeps your app light and your network traffic low, especially if you’re rocking Blazor Server. Say goodbye to heavy, sluggish updates and hello to fast, interactive user experiences.

10. Security You Can Count On

Built on top of ASP.NET Core, Blazor gets all the robust security features that come with the territory. Whether you need authentication, authorization, or secure APIs, you’re covered. Plus, being backed by Microsoft means you get long-term support and a framework that’s designed to last.

Why Blazor is the Ultimate Web Dev Wingman

To wrap it up, Blazor’s real strength lies in how it brings together the best of C# and the .NET ecosystem in a single, unified framework. With Blazor, you can create rich, interactive web apps without the JavaScript headaches. Its component-based structure, real-time capabilities, and powerful tooling make it the go-to choice for .NET developers who want to build modern, scalable web applications with ease.

In short: Blazor is the web development framework that’s got your back. Happy coding!

Yes, Blazor Server can scale!

Image
From the very beginning of the release of Blazor Server naysayers have incorrectly stated that Blazor Server can not scale.  They usually state that the limit is 5,000 concurrent users. There are several misconceptions and wrong assumptions about their statement.  Let's break it down and get a better understanding of Blazor server-side scaling. What is the "limit" for users When Microsoft talks about the need to scale an application, what they are saying is that when a normal response for any concurrent user is taking longer than 200 ms, the system is not performant and needs to scale. We will accept that definition: If any normal user response is taking longer than 200 ms, the system needs to scale for concurrent users. By a normal response, we are referring to a page get, a post, etc.  Large database access requests would not be included in this measurement. What is scaling There are 2 common ways to scale, scale, out horizontally, and scale-up, up vertically. In our di

Blazor new and improved Search Box

 Back in March, I posted a new Blazor data grid with a search box ( see post ).  Since then I have found a new and improved search box that I wanted to implement.  The search part is implemented the same.  What I added was the ability for the user to narrow down the search by selecting which field they wanted to search on.  This will help the user find what they are looking for and in a large collection, the search will end up being faster. The goal of making the change was to make the search box a new component and have it handle the UI functionality part. Prep Work Here is the prep work I did before adding the search box: Started with the source code from the post listed above. Upgraded the project to .Net 5 Upgraded the Nuget packages that were out of date. Ensured every build and run. Change to a Component I wanted to create a component for the search box so I could use it in other applications.   1. Create a Folder under UIControls called "SearchBox" 2. Created a new raz

Blazor - Cool Blur Loading Page

Image
  I was working on a project and wanted an original way of showing the user the application was loading besides using the normal "Loading...." text.  I came across a website page and thought I could refactor that into what I was looking for. When my application starts, it displays a full-screen image with a count down while the page loads.  As a special effect, I want to unblur the image the closer it gets to the applicaiton finishing loading.  Once the teh count down is done, we pause for 1 sec, for effect, then proceed to the application.  I think it turned out pretty cool.  See the demo here . I used the server side Blazor project template in my example, but the code should work on any Blazor template. Template changes 1. Rename the original Index.razor page to "home".  Besure to change the routing at the top of the page as well.      @page "/home" 2. Create a new Index.razor page     a. Add routing           @page "/"           @page "/i
