Vue.js vs. Angular: Key Differences

While both Vue.js and Angular are popular front-end frameworks for building web applications, they differ in several key aspects:

1. Design Philosophy:

• Vue.js: Progressive framework - encourages a gradual learning curve and flexibility, starting with basic functionality and building upon it.

• Angular: Full-featured framework - provides a structured and opinionated approach with more built-in features and conventions.

2. Data Binding:

• Vue.js: Two-way data binding by default - updates in DOM automatically reflect changes in data, and vice versa.

• Angular: One-way data binding - requires explicit manipulation of data to update the UI, promoting predictable data flow.

3. State Management:

• Vue.js: Built-in options like data property and computed properties for simple state management, with Vuex available for complex cases.

• Angular: Relies on external libraries like Redux or NgRx for state management, requiring additional learning and setup.

4. Template Syntax:

• Vue.js: HTML-based templates with directives for data binding and logic.

• Angular: Uses its own custom template language with specific syntax and bindings.

5. Learning Curve:

• Vue.js: Generally considered easier to learn with its intuitive templates and gradual approach.

• Angular: Steeper learning curve due to its structured nature and custom syntax.

6. Performance:

• Vue.js: Efficient virtual DOM implementation, but potentially less optimized for large-scale applications compared to Angular.

• Angular: Highly optimized virtual DOM with advanced features like Ahead-of-Time (AOT) compilation, beneficial for resource-intensive UIs.

7. Component Structure:

• Vue.js: Single-File Components (SFCs) combine template, script, and style in a single file for organization.

• Angular: Components separated into different files (template, logic, style) for cleaner separation of concerns.

Examples:

• Building a Todo List:

Vue.js:

HTML

<template>
  <ul>
    <li v-for="todo in todos" :key="todo.id">
      {{ todo.text }}
      <button @click="removeTodo(todo.id)">X</button>
    </li>
  </ul>
  <input v-model="newTodo" @keyup.enter="addTodo">
</template>

<script>
export default {
  data() {
    return {
      todos: [{ text: 'Buy groceries' }, { text: 'Do laundry' }],
      newTodo: '',
    };
  },
  methods: {
    addTodo() {
      if (this.newTodo) {
        this.todos.push({ text: this.newTodo });
        this.newTodo = '';
      }
    },
    removeTodo(id) {
      this.todos = this.todos.filter((todo) => todo.id !== id);
    },
  },
};
</script>

Angular:

HTML

<ul>
  <li *ngFor="let todo of todos">{{ todo.text }}</li>
</ul>
<input [(ngModel)]="newTodo" (ngKeyup.enter)="addTodo()">

<ng-template>
  <button (click)="removeTodo(todo)">X</button>
</ng-template>

TypeScript

export class AppComponent {
  todos: string[] = ['Buy groceries', 'Do laundry'];
  newTodo: string = '';

  addTodo() {
    if (this.newTodo) {
      this.todos.push(this.newTodo);
      this.newTodo = '';
    }
  }

  removeTodo(index: number) {
    this.todos.splice(index, 1);
  }
}

Choosing the Right Framework:

Consider your project needs, team skills, and desired development style:

• Vue.js: Faster to learn, ideal for smaller projects or teams new to JS frameworks, provides flexibility and ease of use.

• Angular: Suited for large, complex applications, prioritizes performance and scalability, requires initial learning investment but offers a structured and reliable approach.

Both frameworks are powerful tools, and the choice ultimately depends on your specific goals and requirements.
