Overview

Build well-organized Vue 3 applications using Composition API, proper file organization, and TypeScript for type safety and maintainability.

When to Use

• Large-scale Vue applications
• Component library development
• Reusable composable hooks
• Complex state management
• Performance optimization

Quick Start

Minimal working example:

// useCounter.ts (Composable)
import { ref, computed } from 'vue';

export function useCounter(initialValue = 0) {
  const count = ref(initialValue);

  const doubled = computed(() => count.value * 2);
  const increment = () => count.value++;
  const decrement = () => count.value--;
  const reset = () => count.value = initialValue;

  return {
    count,
    doubled,
    increment,
    decrement,
    reset
  };
}

// Counter.vue
<template>
  <div class="counter">
    <p>Count: {{ count }}</p>
    <p>Doubled: {{ doubled }}</p>
// ... (see reference guides for full implementation)
