Getting Started with Blazor: Build Web Apps Using C#

Blazor is a web framework created by Microsoft that lets you build interactive websites using C# instead of JavaScript. It’s part of ASP.NET Core and uses Razor syntax (a mix of HTML and C#) to create rich user interfaces.

If you're a .NET developer, Blazor lets you use your existing skills to build both the backend and frontend of web apps—all in one language.

 

Two Ways to Run Blazor

Blazor offers two hosting models:

1. Blazor WebAssembly (WASM)

  • Runs directly in the browser.
  • Doesn’t need a server for every UI update.
  • Great for apps that work mostly on the client side.

2. Blazor Server

  • Runs on the server and updates the UI in real time using SignalR.
  • Light load on the browser but requires a constant internet connection.

 

Why Use Blazor?

Here’s why many developers are choosing Blazor:

Use C# Everywhere
No need to learn JavaScript or frameworks like Angular or React. You can write both backend and frontend code in C#.

Share Code Easily
Use the same models, validation rules, and business logic on both the client and server.

Build with Components
Blazor apps are made of reusable components—similar to how React or Angular works.

Part of the .NET Ecosystem
Blazor works smoothly with tools like Entity Framework Core, SignalR, and ASP.NET Core Identity.

Great Developer Tools
Use Visual Studio, Hot Reload, and IntelliSense to build faster and with fewer bugs.

Supports WebAssembly
Blazor WebAssembly apps can run offline and in secure environments.

 

What Can You Build with Blazor?

Blazor is flexible and powerful. You can use it to build:

Admin Dashboards & Internal Tools
HR systems, inventory management, finance apps, and more.

Single Page Applications (SPA)
Modern web apps with dynamic pages, similar to Angular or React apps.

Progressive Web Apps (PWA)
Apps that work offline and can be installed like mobile apps.

Real-Time Apps
Chat apps, live dashboards, or anything that needs real-time updates.

E-Commerce Platforms
Shopping carts, product pages, checkout systems.

Content Management Systems (CMS)
Custom blogs or content platforms.

Data-Driven Forms and Reports
CRUD apps with form validation, data entry, and reporting.

 

When to Use Blazor

Blazor is a great choice if:

  • Your team knows C# and wants to build web apps without switching to JavaScript.
  • You're building a business or enterprise app where code sharing and maintainability are important.
  • You need to integrate tightly with other ASP.NET Core features.
  • You want to build modern, interactive apps using familiar .NET tools.

 

Conclusion

Blazor makes it easier for C# developers to build full-featured web apps without learning JavaScript. Whether you're creating dashboards, SPAs, real-time apps, or even PWAs, Blazor is a solid option that fits perfectly into the .NET world.

It’s simple, powerful, and developer-friendly—perfect for modern web development with C#.

Promises in Angular

-
Promises in Angular In Angular,  Promises  provide a mechanism for handling  asynchronous operations  that resolve a  single value  or an  error  in the future. They are ideal for tasks that complete once, such as API calls or timers. Key Features of Promises Promises resolve only once—either with a success value (resolve) or an error (reject). They do not support multiple emissions like Observables. Promises begin executing  immediately  when they are created. They are not lazy and cannot be deferred like Observables. Once a Promise starts, it  cannot be cancelled . This limits their flexibility in situations where you may want to abort the operation. Promises work seamlessly with async/await, making asynchronous code easier to write and understand. Typical Use Cases ·       One-time data fetching ·     ...

Mastering Your Angular Workflow: Essential CLI Commands for Efficient Development

Mastering Your Angular Workflow: Essential CLI Commands for Efficient Development The Angular CLI (Command Line Interface) is a cornerstone of modern Angular development. It streamlines project setup, code generation, testing, and deployment, empowering developers to focus on building maintainable and scalable applications. This guide covers the most essential Angular CLI commands to help you optimize your workflow from project creation to deployment and beyond.   1. Creating a New Angular Project Use the ng new command to initialize a new Angular workspace. Example: Create a standalone app with SCSS and routing (without Server-Side Rendering): ng new PracticeAngular --routing --standalone --style=scss --no-ssr Flag Breakdown: --routing: Sets up Angular Router. --standalone: Uses standalone components (no NgModules). --style=scss: Uses SCSS for styling. --no-ssr: Skips Server-Side Rendering setup.   2. Accessing CLI Help The CLI includes built-...

Observables in Angular

Observables in Angular In Angular,  Observables  are a foundational mechanism for managing asynchronous data streams and event handling. They offer a powerful, flexible way to react to changing data over time.   Key Features of Observables Unlike Promises that emit a single value, Observables can emit multiple values over time — ideal for continuous streams like user input, live data, or WebSockets. Observables are lazy — they only start emitting values when explicitly subscribed to. This improves performance and avoids unnecessary computation. You can unsubscribe from an Observable using .unsubscribe() to clean up resources and prevent memory leaks. Observables leverage the  RxJS  library, which provides a rich set of operators like: map, filter, debounceTime, mergeMap, etc. These enable powerful, declarative transformations and compositions of data streams. Observables are deeply embedded...
