React.js vs Angular vs Blazor: Choosing the Right Framework for Your Web Project
When building modern web applications, React.js, Angular, and Blazor are three popular options. Each has distinct advantages and is suited for different development needs.
- React.js is a flexible JavaScript library for building dynamic UIs.
- Angular is a TypeScript-based full framework from Google.
- Blazor is a C#-based framework by Microsoft for web apps running on WebAssembly.
So, how do they compare? Let’s explore!
Quick Comparison: React.js vs Angular vs Blazor
Feature | React.js ⚛ | Angular 🔴 | Blazor 🟣 |
Developed By | Meta (Facebook) | Microsoft | |
Release Year | 2013 | 2010 | 2018 |
Language | JavaScript, JSX | TypeScript | C#, Razor |
Architecture | Component-Based | MVC | Component-Based |
Rendering | Client-Side (CSR) | CSR & SSR | WebAssembly & Server-Side |
Performance | High (Virtual DOM) | Moderate (Two-way binding overhead) | Slower (WebAssembly overhead) |
SEO | Requires SSR (Next.js) | Good with SSR | Requires optimization |
Learning Curve | Moderate | Steep | Moderate (for .NET developers) |
Best For | SPAs, UI-focused apps | Enterprise apps | .NET-based apps |
📌 Need flexibility? → Choose React.js
📌 Need a structured framework? → Choose Angular
📌 Already using .NET? → Choose Blazor
React.js: The Lightweight JavaScript Library
React.js is a fast and flexible UI library for building component-based applications.
Pros of React.js:
✔ High performance due to Virtual DOM
✔ Reusable components for efficient development
✔ Massive community support and ecosystem
Cons of React.js:
✖ SEO requires SSR setup (Next.js)
✖ Requires third-party libraries for state management
💡 Used by: Facebook, Instagram, Netflix, Airbnb
Angular: The Structured Framework for Enterprise Apps
Angular is a full-fledged framework offering a structured development approach.
Pros of Angular:
✔ Comprehensive framework with built-in tools
✔ Good for large-scale, enterprise applications
✔ Strong support for Server-Side Rendering (SSR) and PWAs
Cons of Angular:
✖ Steep learning curve due to TypeScript and complex architecture
✖ Heavier framework compared to React.js
💡 Used by: Google, Microsoft, IBM, Upwork
📖 “विद्यया विन्दतेऽमृतम्।”
“Through knowledge, one attains immortality.”
Like mastering Angular, gaining deep knowledge in a structured framework takes effort but provides long-term benefits.
Blazor: The .NET Framework for WebAssembly
Blazor allows C# developers to build web applications using WebAssembly instead of JavaScript.
Pros of Blazor:
✔ Leverages existing C#/.NET knowledge
✔ Runs directly in the browser via WebAssembly
✔ Eliminates JavaScript dependencies for .NET developers
Cons of Blazor:
✖ Slower performance due to WebAssembly overhead
✖ Limited third-party ecosystem compared to React.js or Angular
💡 Used by: Microsoft-based applications, .NET developers
Final Verdict: Which One Should You Choose?
If You Want | Best Choice |
A lightweight UI library for SPAs | ⚛ React.js |
A full-fledged framework for structured development | 🔴 Angular |
A .NET-based framework for WebAssembly | 🟣 Blazor |
🚀 For dynamic, UI-focused apps → Choose React.js
🏢 For large-scale, structured applications → Choose Angular
💻 For .NET-based web apps → Choose Blazor
Conclusion
Each framework serves a different purpose:
🔹 React.js is best for flexible, component-based applications.
🔹 Angular is perfect for enterprise-level, structured projects.
🔹 Blazor is ideal for .NET developers wanting WebAssembly-based web apps.
