Choosing the Right Frontend Framework: Angular, Vue, or Blazor

Introduction

The modern web development landscape offers a wide variety of frameworks and libraries, each designed to help developers build interactive, scalable, and maintainable applications. Among the most popular choices today are Angular, Vue.js, and Blazor

Angular and Vue have been leading the JavaScript ecosystem for years, providing developers with powerful tools to create dynamic single-page applications. Blazor, on the other hand, represents a newer and unique approach from Microsoft — allowing developers to build full-stack web applications using C# and .NET, eliminating the need to rely solely on JavaScript.

we’ll explore the key differences between these three frameworks, including their languages, performance, folder structures, and use cases, to help you decide which is the best fit for your next project.

Comparison Table

Here’s a detailed comparison between Angular, Vue, and Blazor, covering their architecture, language, performance, ecosystem, and use cases to help you understand the differences clearly:

Aspect

Angular

Vue.js

Blazor

Primary Language

TypeScript (JavaScript superset)

JavaScript (or TypeScript optionally)

C# (compiled to WebAssembly or server-rendered)

Developed By

Google

Evan You (former Google engineer) & open-source community

Microsoft

Core Purpose

Enterprise-scale, feature-rich front-end framework

Lightweight, progressive framework for flexible UI development

Build .NET-based web apps using C# instead of JavaScript

Architecture

Full MVC / MVVM framework

View layer focused with optional ecosystem for state management & routing

Component-based, similar to React/Angular, with WebAssembly support

Size / Footprint

Heavy – large initial bundle

Lightweight – small initial bundle

Medium to Heavy – larger than Vue, smaller than Angular (depends on hosting model)

Performance

Good, but initial load can be heavy due to size

Excellent for small-to-medium apps due to smaller size

Good, but WebAssembly apps may have slightly longer initial load

Learning Curve

Steep – complex concepts like Dependency Injection, RxJS, modules

Gentle – easier to learn, especially for beginners

Moderate for C# developers, steeper for non-.NET developers

Community & Ecosystem

Very large & mature (Google backing, enterprise adoption)

Growing steadily with vibrant open-source community

Growing, but smaller than Angular or Vue

Tooling

Angular CLI, strong IDE support (VS Code, WebStorm)

Vue CLI, Vite, VS Code support

Excellent tooling via Visual Studio and .NET ecosystem

Type Safety

Strong typing with TypeScript built-in

Optional TypeScript support

Strong typing with C#

Best For

Enterprise apps, large-scale projects, teams with TypeScript skills

Startups, small-to-medium apps, rapid development, progressive enhancement

Teams with strong .NET and C# background who want to build client-side apps without JavaScript

Rendering Approach

Client-side rendering (CSR) with Angular Universal for SSR

CSR with support for SSR (Nuxt.js)

Two modes: WebAssembly (client-side) or Server-side (Blazor Server)

Maturity

Mature and battle-tested (since 2010)

Mature but lighter (since 2014)

Newer (introduced in 2018) but rapidly evolving

Integration

Works well with REST APIs, GraphQL, microservices

Similar integrations, very flexible

Deep integration with .NET backend, REST, SignalR


Project Structure

Angular projects are opinionated and strictly organized because Angular is a full-fledged framework.
It uses modules, components, and services, with a strong emphasis on separation of concerns.

Vue.js projects are more flexible and minimalistic, giving developers freedom to organize files.It’s lightweight compared to Angular and does not enforce a strict hierarchy by default.

Blazor projects are .NET projects, so they resemble ASP.NET Core project structures, with .csproj files and C# code.

Aspect

Angular

Vue.js

Blazor

Root Component

app.component.ts

App.vue

App.razor

Entry Point

main.ts

main.js

Program.cs

Routing

Built-in Angular Router folder

Optional router/ folder

Built into Pages/ via .razor files

State Management

Services + RxJS + NgRx (optional)

Vuex/Pinia (optional)

C# services or DI

Static Files

src/assets/

public/ or src/assets/

wwwroot/

Tests Folder

e2e/ and src/app/...spec.ts

No default, add manually

Client.Tests/ or custom

Strictness

Very strict and opinionated

Very flexible and minimalistic

Strict but follows .NET conventions

Single File Component

Split files: .ts, .html, .css

.vue (HTML, CSS, JS together)

.razor (HTML + C# together)
