| 7 | |
| 8 | Lifecycle hooks for slide components. |
| 9 | |
| 10 | ## Available Hooks |
| 11 | |
| 12 | ```ts |
| 13 | import { onSlideEnter, onSlideLeave, useIsSlideActive } from '@slidev/client' |
| 14 | |
| 15 | const isActive = useIsSlideActive() |
| 16 | |
| 17 | onSlideEnter((to, from) => { |
| 18 | // Called when slide becomes active |
| 19 | }) |
| 20 | |
| 21 | onSlideLeave((to, from) => { |
| 22 | // Called when slide becomes inactive |
| 23 | }) |
| 24 | ``` |
| 25 | |
| 26 | ## Important |
| 27 | |
| 28 | Do NOT use `onMounted` / `onUnmounted` in slides - component instance persists even when slide is inactive. |
| 29 | |
| 30 | Use `onSlideEnter` and `onSlideLeave` instead. |
| 31 | |
| 32 | ## Use Cases |
| 33 | |
| 34 | - Start/stop animations |
| 35 | - Play/pause media |
| 36 | - Initialize/cleanup resources |
| 37 | - Track analytics |
