Vue Application Structure
Table of Contents
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>
