Vue.js Development

Component Creation Pattern

Always use this structure for Vue 3 components in this project:

<script setup lang="ts">
import { ref, computed, onMounted } from 'vue'
import { useTaskStore } from '@/stores/tasks'

// Props interface
interface Props {
  taskId?: string
  readonly?: boolean
}

const props = withDefaults(defineProps<Props>(), {
  readonly: false
})

const emit = defineEmits<{
  update: [task: Task]
  delete: [id: string]
}>()

// Store integration
const taskStore = useTaskStore()

// Computed properties
const filteredTasks = computed(() =>
  taskStore.tasks.filter(task => task.status === 'active')
)

// Methods
const handleUpdate = (task: Task) => {
  emit('update', task)
}

// Lifecycle
onMounted(() => {
  taskStore.loadTasks()
})
</script>

<template>
  <div class="component-container">
    <!-- Component content -->
  </div>
</template>

<style scoped>
.component-container {
  background: var(--color-surface);
  padding: var(--spacing-md);
}
</style>

Key Requirements

• Always use <script setup lang="ts">
• Use design tokens: var(--color-*), var(--spacing-*)
• Include proper TypeScript interfaces
• Use Pinia stores for state management
• Follow import organization: Vue → Stores → Components → Composables

Common Patterns

• Event handling with proper modifiers
• Reactive data with ref() and reactive()
• Lazy loading for async components
• Proper cleanup in onUnmounted()

This skill ensures consistent Vue 3 development patterns across the productivity application.
