Vue.js Best Practices

Composition API (Vue 3)

• Use script setup for cleaner code
• Use ref() for primitives, reactive() for objects
• Use computed() for derived state
• Use watch/watchEffect for side effects
• Create composables for reusable logic

Component Design

• One component per file
• Use defineProps with TypeScript
• Use defineEmits for events
• Keep templates readable
• Use slots for flexibility
