# Vue 3 Conventions
|
|
|
|
## Composition API with `<script setup>`
|
|
Always use `<script setup lang="ts">`. Never use Options API.
|
|
|
|
## Component Organization Order
|
|
1. Imports — external, then internal
|
|
2. Props — with TypeScript-style validation
|
|
3. Emits — explicitly defined
|
|
4. State (refs and reactive)
|
|
5. Computed — derived values, always pure
|
|
6. Watchers — side effects only
|
|
7. Methods — business logic
|
|
8. Lifecycle hooks — ordered by execution
|
|
9. Expose — public API (if needed)
|
|
|
|
## File Organization
|
|
```
|
|
src/
|
|
components/
|
|
ui/ # Primitives (Button, Card, Badge, Input)
|
|
chat/ # Chat window, message list, input
|
|
content-panel/ # Side panel for surfaced content
|
|
renderers/ # Content type renderers
|
|
layout/ # Shell, split-pane, responsive containers
|
|
composables/ # Shared composition functions (useTheme, useMedia, useCrypto)
|
|
stores/ # Pinia stores
|
|
plugins/ # Plugin system
|
|
types/ # Shared TypeScript types
|
|
styles/ # Global CSS, themes, design tokens
|
|
utils/ # Pure utility functions
|
|
```
|
|
|
|
## Naming Conventions
|
|
- Components: PascalCase (`ProjectCard.vue`)
|
|
- Composables: camelCase, prefixed with "use" (`useTheme.ts`)
|
|
- Props: camelCase in JS, kebab-case in templates
|
|
- Boolean props: prefix with `is`, `has`, `can`, `should`
|
|
- Handler props: prefix with `on` (`onClick`, `onClose`)
|
|
- Emits: explicit, kebab-case in templates (`project:updated`)
|
|
|
|
## Props — Always Validate
|
|
```typescript
|
|
defineProps({
|
|
title: { type: String, required: true },
|
|
count: { type: Number, default: 0 },
|
|
status: {
|
|
type: String as PropType<'pending' | 'active' | 'complete'>,
|
|
default: 'pending'
|
|
}
|
|
})
|
|
```
|
|
|
|
Never use array-style props: `defineProps(['title', 'count'])`
|
|
|
|
## Reactive State
|
|
- `ref` for primitives and single values
|
|
- `reactive` for objects with multiple properties
|
|
- `computed` for derived state (never side effects in computed)
|
|
- `shallowRef` for large objects that change at top level only
|
|
|
|
## Templates — Keep Clean
|
|
Move complex logic to computed properties or methods. No inline logic in templates. Use `v-if` for infrequent toggles, `v-show` for frequent ones.
|
|
|
|
## Composables
|
|
- One responsibility per composable
|
|
- Return only what's needed
|
|
- Handle cleanup in `onUnmounted`
|
|
- Make composables testable
|
|
|
|
## Performance
|
|
- Lazy load heavy components: `defineAsyncComponent(() => import(...))`
|
|
- Use `shallowRef` for large lists
|
|
- Use `:key` with unique identifiers, never index
|
|
- Avoid reactive objects in templates (create in script)
|
|
|
|
## Error Handling
|
|
Use `onErrorCaptured` for component-level error boundaries. Always handle async errors with try/catch/finally pattern (loading, error, data states).
