+# Component Patterns
+
+## Props Best Practices
+
+- Type your props: `defineProps<{msg: string, count?: number}>()`
+- Required props have no `?`—TypeScript enforces
+- Default values: `withDefaults(defineProps<Props>(), {count: 0})`
+- Props are readonly—never mutate, emit event to parent instead
+
+## Emit Patterns
+
+- Type your emits: `defineEmits<{(e: 'update', value: string): void}>()`
+- Emit returns boolean if event handler returns false
+- Vue 3.3+ shorthand: `defineEmits<{update: [value: string]}>()`
+- Always emit for changes—maintain one-way data flow
+
+## v-model Patterns
+
+- `v-model` = `:modelValue` + `@update:modelValue`
+- Multiple v-model: `v-model:title`, `v-model:content`—different props
+- `defineModel()` (3.4+) creates ref that syncs automatically—much simpler
+- v-model modifiers: `.trim`, `.number`, `.lazy`—access via `modelModifiers`
+
+## Slots Patterns
+
+- Default slot: `<slot></slot>`—or `<slot>fallback content</slot>`
+- Named slots: `<slot name="header">` + `<template #header>`
+- Scoped slots: `<slot :item="item">` + `<template #default="{item}">`
+- `$slots.header?.()` to check if slot provided
+
+## Dynamic Components
+
+- `<component :is="componentName">`—switch between components
+- `<KeepAlive>` preserves state when switching—cached in memory
+- `include`/`exclude` props on KeepAlive—control which are cached
+- `max` prop limits cache size—LRU eviction
+
+## Async Components
+
+- `defineAsyncComponent(() => import('./Comp.vue'))`—lazy loading
+- Loading component: `loadingComponent` option—shown while loading
+- Error component: `errorComponent` option—shown on load failure
+- Combine with `<Suspense>` for coordinated loading states
+
+## Teleport
+
+- `<Teleport to="body">`—render content outside component tree
+- Useful for modals, dropdowns, tooltips—need to escape overflow/z-index
+- `disabled` prop for conditional teleporting
+- Events still bubble in Vue component tree—not DOM tree
+
+## Provide/Inject
+
+- `provide('key', value)` in ancestor—available to all descendants
+- `inject('key', defaultValue)` to receive
+- Provide reactive value for reactive inject—`provide('count', ref(0))`
+- Symbol keys for type safety—avoid string collisions
