# Vue 3 Composition API Project Rules

## Vue 3 Composition API Best Practices
- Use setup() function for component logic
- Utilize ref and reactive for reactive state
- Implement computed properties with computed()
- Use watch and watchEffect for side effects
- Implement lifecycle hooks with onMounted, onUpdated, etc.
- Utilize provide/inject for dependency injection
- Use vue 3.5 style of default prop declaration. Example:

```typescript
const { nodes, showTotal = true } = defineProps<{
  nodes: ApiNodeCost[]
  showTotal?: boolean
}>()
```

- Organize vue component in <template> <script> <style> order

## Project Structure
```
src/
  components/
  constants/
  composables/
  views/
  stores/
  services/
  App.vue
  main.ts
```

## Styling Guidelines
- Use Tailwind CSS for styling
- Implement responsive design with Tailwind CSS

## PrimeVue Component Guidelines
DO NOT use deprecated PrimeVue components. Use these replacements instead:
- Dropdown → Use Select (import from 'primevue/select')
- OverlayPanel → Use Popover (import from 'primevue/popover')
- Calendar → Use DatePicker (import from 'primevue/datepicker')
- InputSwitch → Use ToggleSwitch (import from 'primevue/toggleswitch')
- Sidebar → Use Drawer (import from 'primevue/drawer')
- Chips → Use AutoComplete with multiple enabled and typeahead disabled
- TabMenu → Use Tabs without panels
- Steps → Use Stepper without panels
- InlineMessage → Use Message component

## Development Guidelines
1. Leverage VueUse functions for performance-enhancing styles
2. Use lodash for utility functions
3. Use TypeScript for type safety
4. Implement proper props and emits definitions
5. Utilize Vue 3's Teleport component when needed
6. Use Suspense for async components
7. Implement proper error handling
8. Follow Vue 3 style guide and naming conventions
9. Use Vite for fast development and building
10. Use vue-i18n in composition API for any string literals. Place new translation entries in src/locales/en/main.json
11. Never use deprecated PrimeVue components listed above
