Cursor Rules for Vue 3 and Nuxt: AI Dev Guide 2026

Based on your detailed comparison and rules, it seems clear that using defineProps, defineEmits, and defineModel with TypeScript generics in Vue 3 provides a more robust and type-safe approach compared to the old way of declaring props and emitting events.

Here's how you can apply these principles effectively:

Rule 1: Use Composition API + Composables

Example:

typescript
 
1<script setup lang="ts">
2import { defineProps, defineEmits } from 'vue';
3import { useLogger } from '@/composables/useLogger';
4
5interface User {
6  id: number;
7  name: string;
8}
9
10const props = defineProps<{
11  user: User;
12  editable?: boolean;
13}>();
14
15const emit = defineEmits<{ 
16  (event: 'save', user: User): void; 
17}>();
18
19const { log } = useLogger('UserCard');
20
21const editing = ref(false);
22const draftName = ref('');
23
24const displayName = computed(() => draftName.value || props.user.name);
25
26function startEdit() {
27  editing.value = true;
28  draftName.value = props.user.name;
29}
30
31function save() {
32  emit('save', { ...props.user, name: draftName.value });
33  editing.value
