What Is Blazor?

Blazor is a web UI framework within the ASP.NET Core ecosystem that enables developers to build interactive and dynamic web apps using C# instead of JavaScript.

Blazor stands for Browser + Razor, combining the Razor templating engine with WebAssembly or SignalR-powered interactivity.

Blazor Hosting Models: Server vs WebAssembly

🔹 Blazor Server

Runs on the server using SignalR for UI updates

Thin client footprint

Fast initial load

Great for intranet and enterprise apps

🔹 Blazor WebAssembly (WASM)

Runs entirely in the browser via WebAssembly

Offline support

No server round-trips for UI logic

Ideal for public-facing, client-heavy apps

Getting Started with Blazor

1. Create a Blazor Project

bash

CopyEdit

dotnet new blazorwasm -n MyBlazorApp cd MyBlazorApp dotnet run

Or for server-side:

bash

CopyEdit

dotnet new blazorserver -n MyBlazorServerApp

2. Sample Component: Counter.razor

razor

CopyEdit

<h3>Counter</h3> <p>Current count: @count</p> <button class="btn btn-primary" @onclick="IncrementCount">Click me</button> @code {    private int count = 0;    private void IncrementCount()    {        count++;    } }

This shows how simple it is to bind UI logic and events using pure C# code.

Why Choose Blazor?

✅ Full-stack development with C#
✅ No JavaScript required (though interoperable)
✅ Strong tooling support in Visual Studio and VS Code
✅ Component-based architecture
✅ Seamless .NET integration
✅ Code reuse between frontend and backend with shared libraries

Key Features of Blazor

🧩 Reusable Components

⚙️ Dependency Injection (DI)

🌐 Routing with Razor Pages

🔐 Built-in Authentication & Authorization

📦 JavaScript Interop for third-party libraries

⚡ Real-time updates via SignalR (for Blazor Server)

Blazor Use Cases

Blazor is ideal for:

🚀 Enterprise dashboards and internal tools

🛍️ E-commerce storefronts with rich UX

📱 Progressive Web Apps (PWAs)

⚙️ Admin panels and CMS systems

💼 Line-of-business applications

JavaScript Interoperability in Blazor

You can still use JS when needed:

csharp

CopyEdit

@inject IJSRuntime JS <button @onclick="CallJS">Call JS</button> @code {    async Task CallJS() {        await JS.InvokeVoidAsync("alert", "Hello from Blazor!");    } }

This flexibility allows integration with libraries like Chart.js, Leaflet, or Bootstrap plugins.

Deployment Options

Static Web Hosting (Blazor WASM) – Azure Static Web Apps, GitHub Pages, Firebase

Server Hosting (Blazor Server) – Azure App Services, IIS, Docker containers

Hybrid (MAUI + Blazor) – Build native desktop and mobile apps using Blazor!

Performance Considerations

Blazor WASM: Use AOT (Ahead-of-Time) compilation to improve load and runtime performance

Blazor Server: Minimize latency with signal optimization and pre-rendering

Use Lazy Loading and component-level rendering for complex UIs

Real-World Adoption of Blazor

Blazor is already powering apps in:

Healthcare platforms

Financial dashboards

Government portals

Enterprise SaaS applications

Manufacturing control systems

With Microsoft’s continued investment and community support, Blazor is becoming a mainstream SPA framework.

Conclusion

Blazor enables .NET developers to build modern, dynamic, and fully interactive web applications using just C# and Razor—no JavaScript required. With powerful tooling, a strong ecosystem, and flexible hosting models, Blazor offers a compelling alternative to frameworks like Angular, React, and Vue.
