Module 1: Understanding React, Angular, and Vue in 2025
1.1 React: The Component-Driven Library
React, launched in 2013 by Meta, is technically a library, not a full framework. It focuses on building reusable UI components using a Virtual DOM for efficient updates. In 2025, React 19 brings features like a new compiler for automatic memoization and improved concurrent rendering, making it faster for complex UIs.
Real-Life Relevance: A freelancer building a dynamic dashboard for a startup (e.g., a fitness app tracking user workouts) benefits from React’s flexibility to reuse components like charts or buttons across pages.
Basic Scenario: A to-do list app. Advanced Scenario: A Next.js-powered e-commerce site with real-time inventory updates via WebSockets.
1.2 Angular: The All-Inclusive Framework
Angular (version 18+ in 2025), maintained by Google, is a comprehensive framework with built-in tools for routing, forms, HTTP requests, and more. Its TypeScript foundation enforces strict typing, ideal for large teams.
Real-Life Relevance: A corporate developer building an HR portal for employee management (e.g., leave requests, payroll) leverages Angular’s structure for maintainability.
Basic Scenario: A simple form submission app. Advanced Scenario: A micro-frontend banking app with lazy-loaded modules.
1.3 Vue: The Progressive Framework
Vue 3 (with Vue 4 betas in 2025) is lightweight and adaptable, allowing developers to integrate it incrementally. Its single-file components (SFCs) combine HTML, CSS, and JavaScript for clean code.
Real-Life Relevance: An indie developer creating an interactive portfolio or a real-time chat app for a gaming community loves Vue’s simplicity and performance.
Basic Scenario: A counter app. Advanced Scenario: A decentralized app (dApp) using Pinia for state management and blockchain integration.
1.4 Pros and Cons Snapshot
Framework | Pros | Cons |
---|---|---|
React | Huge ecosystem, fast Virtual DOM, flexible for small/large projects | Needs third-party libs (e.g., Redux, React Router), complex state management for large apps |
Angular | Comprehensive tooling, TypeScript-first, enterprise-ready | Steep learning curve, heavier bundle size |
Vue | Easy to learn, lightweight, performant | Smaller community, less suited for massive enterprise apps without add-ons |
1.5 Alternatives
- Svelte: Compile-time framework for minimal runtime overhead.
- Solid.js: React-like with better performance via fine-grained reactivity.
- Preact: Lightweight React alternative for smaller apps.
- Alpine.js: For minimal reactive UIs without heavy frameworks.
1.6 Best Practices and Standards
- Use semantic versioning (e.g., ^18.2.0 for React).
- Follow accessibility (WCAG 2.1) with ARIA roles.
- Use ESLint/Prettier for consistent code.
- Adhere to REST or GraphQL standards for APIs.
Module 2: Setup and Basic Tutorials – Getting Started
Let’s set up each framework and build a simple app. Assume Node.js (v20+) is installed.
2.1 React: Setup and Counter App
Setup: Use Vite for speed (npm create vite@latest) or Create React App (npx create-react-app my-app).
Basic Tutorial: Counter App
// src/App.jsx
import { useState } from 'react';
function App() {
const [count, setCount] = useState(0);
return (
<div style={{ textAlign: 'center', padding: '20px' }}>
<h1>React Counter: {count}</h1>
<button onClick={() => setCount(count + 1)}>Increment</button>
<button onClick={() => setCount(count - 1)}>Decrement</button>
</div>
);
}
export default App;
Run: npm run dev. This uses React’s useState hook for reactive state.
Interactive Idea: Fork this on CodeSandbox to tweak styles or add reset functionality.
Pros: Simple API, fast prototyping. Cons: No built-in routing.
Best Practices: Use functional components, avoid inline styles for production (use CSS modules or Tailwind).
2.2 Angular: Setup and Hello World
Setup: Install Angular CLI (npm install -g @angular/cli), then ng new my-app.
Basic Tutorial: Hello World Component
// src/app/app.component.ts
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
template: `
<div style="text-align: center; padding: 20px;">
<h1>Hello, {{ name }}!</h1>
<input [(ngModel)]="name" placeholder="Enter your name" />
</div>
`,
})
export class AppComponent {
name: string = 'Angular';
}
Add FormsModule to app.module.ts for ngModel. Run: ng serve.
Interactive Idea: Use StackBlitz for Angular playgrounds.
Pros: Two-way binding simplifies forms. Cons: Verbose setup for beginners.
Best Practices: Use standalone components (Angular 17+), follow Angular’s official style guide.
2.3 Vue: Setup and Counter App
Setup: npm create vue@latest (uses Vite under the hood).
Basic Tutorial: Reactive Counter
<!-- src/App.vue -->
<script setup>
import { ref } from 'vue';
const count = ref(0);
</script>
<template>
<div style="text-align: center; padding: 20px;">
<h1>Vue Counter: {{ count }}</h1>
<button @click="count++">Increment</button>
<button @click="count--">Decrement</button>
</div>
</template>
Run: npm run dev. Uses Vue’s Composition API with ref for reactivity.
Interactive Idea: Try on Vue SFC Playground.
Pros: Intuitive, lightweight. Cons: Custom directives can confuse newbies.
Best Practices: Prefer <script setup>, use TypeScript for larger apps.
2.4 Real-Life Application
- Freelancer: React for a portfolio site (quick to spin up).
- Corporate Dev: Angular for a CRM dashboard (structured).
- Indie Dev: Vue for a SaaS MVP (fast and flexible).
Module 3: Intermediate Tutorials – Building Real-World Features
Let’s scale up with a todo list app, including state management and API integration.
3.1 React: Todo List with Context API
Scenario: A task manager for a small team.
// src/App.jsx
import { createContext, useContext, useState } from 'react';
const TodoContext = createContext();
function TodoProvider({ children }) {
const [todos, setTodos] = useState([]);
const addTodo = (text) => setTodos([...todos, { text, done: false }]);
const toggleTodo = (index) => {
const newTodos = [...todos];
newTodos[index].done = !newTodos[index].done;
setTodos(newTodos);
};
return <TodoContext.Provider value={{ todos, addTodo, toggleTodo }}>{children}</TodoContext.Provider>;
}
function TodoList() {
const { todos, toggleTodo } = useContext(TodoContext);
return (
<ul>
{todos.map((todo, index) => (
<li key={index} style={{ textDecoration: todo.done ? 'line-through' : 'none' }}>
<input type="checkbox" checked={todo.done} onChange={() => toggleTodo(index)} />
{todo.text}
</li>
))}
</ul>
);
}
function TodoForm() {
const { addTodo } = useContext(TodoContext);
const [text, setText] = useState('');
return (
<form onSubmit={(e) => { e.preventDefault(); addTodo(text); setText(''); }}>
<input value={text} onChange={(e) => setText(e.target.value)} placeholder="Add todo" />
<button type="submit">Add</button>
</form>
);
}
function App() {
return (
<TodoProvider>
<div style={{ padding: '20px' }}>
<h1>React Todo List</h1>
<TodoForm />
<TodoList />
</div>
</TodoProvider>
);
}
export default App;
Pros: Context API avoids prop drilling. Cons: Complex for large apps (consider Redux Toolkit).
Real-Life: A project management tool for freelancers tracking client tasks.
3.2 Angular: Todo List with Service
Scenario: HR task tracker.
// src/app/todo.service.ts
import { Injectable } from '@angular/core';
import { BehaviorSubject } from 'rxjs';
@Injectable({ providedIn: 'root' })
export class TodoService {
private todos = new BehaviorSubject<{ text: string; done: boolean }[]>([]);
todos$ = this.todos.asObservable();
addTodo(text: string) {
const current = this.todos.getValue();
this.todos.next([...current, { text, done: false }]);
}
toggleTodo(index: number) {
const current = this.todos.getValue();
current[index].done = !current[index].done;
this.todos.next([...current]);
}
}
// src/app/app.component.ts
import { Component } from '@angular/core';
import { TodoService } from './todo.service';
@Component({
selector: 'app-root',
template: `
<div style="padding: 20px;">
<h1>Angular Todo List</h1>
<form (ngSubmit)="addTodo()">
<input [(ngModel)]="todoText" name="todoText" placeholder="Add todo" />
<button type="submit">Add</button>
</form>
<ul>
<li *ngFor="let todo of todos$ | async; let i = index"
[style.textDecoration]="todo.done ? 'line-through' : 'none'">
<input type="checkbox" [checked]="todo.done" (change)="todoService.toggleTodo(i)" />
{{ todo.text }}
</li>
</ul>
</div>
`,
})
export class AppComponent {
todoText = '';
todos$ = this.todoService.todos$;
constructor(public todoService: TodoService) {}
addTodo() {
if (this.todoText) {
this.todoService.addTodo(this.todoText);
this.todoText = '';
}
}
}
Pros: RxJS for reactive programming. Cons: Overkill for small apps.
Real-Life: Employee task dashboard in a corporate intranet.
3.3 Vue: Todo List with Pinia
Scenario: Community task board.

<script setup>
import { storeToRefs } from 'pinia';
import { useTodoStore } from './stores/todo';
const store = useTodoStore();
const { todos } = storeToRefs(store);
const text = ref('');
const addTodo = () => {
if (text.value) {
store.addTodo(text.value);
text.value = '';
}
};
</script>
<template>
<div style="padding: 20px;">
<h1>Vue Todo List</h1>
<form @submit.prevent="addTodo">
<input v-model="text" placeholder="Add todo" />
<button type="submit">Add</button>
</form>
<ul>
<li v-for="(todo, index) in todos" :key="index"
:style="{ textDecoration: todo.done ? 'line-through' : 'none' }">
<input type="checkbox" v-model="todo.done" />
{{ todo.text }}
</li>
</ul>
</div>
</template>
// src/stores/todo.js
import { defineStore } from 'pinia';
import { ref } from 'vue';
export const useTodoStore = defineStore('todo', () => {
const todos = ref([]);
const addTodo = (text) => todos.value.push({ text, done: false });
return { todos, addTodo };
});
Pros: Pinia is lightweight and intuitive. Cons: Less mature than Redux.
Real-Life: A community-driven task board for a gaming guild.
Module 4: Advanced Tutorials – Real-Time Data and APIs

// src/App.jsx
import { useState, useEffect } from 'react';
import axios from 'axios';
function App() {
const [weather, setWeather] = useState(null);
const [city, setCity] = useState('London');
useEffect(() => {
axios.get(`https://api.openweathermap.org/data/2.5/weather?q=${city}&appid=YOUR_API_KEY`)
.then(response => setWeather(response.data))
.catch(error => console.error(error));
}, [city]);
return (
<div style={{ padding: '20px' }}>
<h1>Weather in {city}</h1>
<input value={city} onChange={(e) => setCity(e.target.value)} placeholder="Enter city" />
{weather ? (
<div>
<p>Temperature: {(weather.main.temp - 273.15).toFixed(1)}°C</p>
<p>Condition: {weather.weather[0].description}</p>
</div>
) : (
<p>Loading...</p>
)}
</div>
);
}
export default App;
Pros: Easy HTTP with Axios. Cons: Needs manual error handling.
Real-Life: Travel agency app showing destination weather.
4.2 Angular: Weather App with HttpClient

@Injectable({ providedIn: 'root' })
export class WeatherService {
constructor(private http: HttpClient) {}
getWeather(city: string): Observable<any> {
return this.http.get(`https://api.openweathermap.org/data/2.5/weather?q=${city}&appid=YOUR_API_KEY`);
}
}
// src/app/app.component.ts
import { Component } from '@angular/core';
import { WeatherService } from './weather.service';
@Component({
selector: 'app-root',
template: `
<div style="padding: 20px;">
<h1>Weather in {{ city }}</h1>
<input [(ngModel)]="city" (ngModelChange)="getWeather()" />
<div *ngIf="weather">
<p>Temperature: {{ (weather.main.temp - 273.15).toFixed(1) }}°C</p>
<p>Condition: {{ weather.weather[0].description }}</p>
</div>
<p *ngIf="!weather">Loading...</p>
</div>
`,
})
export class AppComponent {
city = 'London';
weather: any;
constructor(private weatherService: WeatherService) {
this.getWeather();
}
getWeather() {
this.weatherService.getWeather(this.city).subscribe(data => (this.weather = data));
}
}
Pros: Built-in HTTP client, reactive streams. Cons: RxJS learning curve.
4.3 Vue: Weather App with Pinia
<!-- src/App.vue -->
<script setup>
import { ref } from 'vue';
import { useWeatherStore } from './stores/weather';
const store = useWeatherStore();
const { weather } = storeToRefs(store);
const city = ref('London');
const fetchWeather = () => store.fetchWeather(city.value);
watch(city, fetchWeather, { immediate: true });
</script>
<template>
<div style="padding: 20px;">
<h1>Weather in {{ city }}</h1>
