A Comprehensive Comparison: Blazor vs. React vs. Angular

In the fast-evolving world of web development, choosing the right framework is crucial for building dynamic and interactive user interfaces. Three popular contenders in this space are Blazor vs React vs Angular. Each technology offers unique features, advantages, and use cases. In this blog post, we will provide a detailed explanation of each technology, including its architecture, features, and examples, to help you make an informed decision.

Lets compare Blazor vs React vs Angular

1. Blazor:

Blazor is a server-side web framework developed by Microsoft that enables developers to build web applications using C# and .NET. It follows the principle of server-side rendering (SSR), where the application logic runs on the server, and the client-side UI is updated through SignalR for real-time communication. Key features of Blazor include:

  • C# and .NET Integration: Blazor allows developers to leverage their existing C# and .NET skills, libraries, and infrastructure. This integration makes it a preferred choice for developers familiar with the Microsoft ecosystem.
  • Server-side Rendering: Blazor’s SSR approach reduces the initial page load time and provides better SEO support.
  • Real-time Communication: Blazor supports real-time communication through SignalR, enabling developers to build applications with live data updates and instant user interactions.

Sample “Hello World” Program in Blazor:

@page "/hello"

<h3>Hello, Blazor!</h3>

@code {

 protected override void OnInitialized()


 Console.WriteLine("Blazor: Hello World!");




2. React:

React is a JavaScript library developed by Facebook for building user interfaces. It follows a component-based architecture and uses a virtual DOM for efficient updates. Key features of React include:

  • Component-Based Architecture: React encourages the development of reusable and composable components, making it easier to manage complex UI structures.
  • Virtual DOM: React’s virtual DOM efficiently updates only the necessary changes to the actual DOM, resulting in better performance.
  • Large Ecosystem: React has a vast ecosystem with a multitude of third-party libraries, tools, and community support.

Sample “Hello World” Program in React:

import React from 'react';

function HelloWorld() {

 console.log("React: Hello World!");

 return (

 <h3>Hello, React!</h3>



export default HelloWorld;


3. Angular:

Angular, developed by Google, is a comprehensive web framework based on TypeScript. It follows a component-based architecture and offers powerful features for managing state, routing, and form validation. Key features of Angular include:

  • TypeScript: Angular leverages TypeScript’s static typing and features like decorators to provide a more structured and maintainable codebase.
  • Comprehensive Framework: Angular provides built-in support for many aspects of web development, including dependency injection, routing, form validation, and more.
  • Large Community and Ecosystem: Angular has a mature ecosystem with extensive documentation, ready-to-use solutions, and a strong community.

Sample “Hello World” Program in Angular:

import { Component } from '@angular/core';


 selector: 'app-hello-world',

 template: `<h3>Hello, Angular!</h3>`


export class HelloWorldComponent {

 constructor() {

 console.log("Angular: Hello World!");



Comparison Table:

Feature Blazor React Angular
Language C# and .Net JavaScript TypeScript
Rendering Server-side Client-side Client-side
UI Componentization Yes Yes Yes
Virtual DOM No Yes Yes

Learning Curve Low (if familiar with C#/.NET) Low Moderate
Ecosystem Growing ecosystem Vast ecosystem Mature ecosystem
Community Support Growing community Large community Large community
Use Cases Integration with .NET ecosystem, enterprise applications Wide range of applications Enterprise applications
Development Workflow Integrated with .NET Flexible Integrated with TypeScript
Latest Version Blazor 5.0 React 18.0 Angular 13.0
System Requirements .NET 5.0 or later Node.js, NPM Node.js, NPM


Each technology, Blazor, React, and Angular, has its own strengths and target use cases. Blazor is ideal for developers familiar with C# and .NET who want seamless integration with existing infrastructure. React’s component-based architecture and virtual DOM make it suitable for a wide range of applications. Angular is well-suited for building large-scale enterprise applications that require a comprehensive framework with powerful features.

When choosing the right technology, consider your project requirements, team expertise, and specific needs to ensure a successful development journey.
