Basic Usage

import { useMouse } from '@vueuse/core'

const { x, y, sourceType } = useMouse()

Touch is enabled by default. To only detect mouse changes, set touch to false. The dragover event is used to track mouse position while dragging.

const { x, y } = useMouse({ touch: false })

Custom Extractor

It's also possible to provide a custom extractor function to get the position from the event.

import { type UseMouseEventExtractor, useMouse, useParentElement } from '@vueuse/core'

const parentEl = useParentElement()

const extractor: UseMouseEventExtractor = event => (
  event instanceof Touch
    ? null
    : [event.offsetX, event.offsetY]
)

const { x, y, sourceType } = useMouse({ target: parentEl, type: extractor })

Touch is enabled by default. To only detect mouse changes, set touch to false. The dragover event is used to track mouse position while dragging.

const { x, y } = useMouse({ touch: false })

Component Usage

This function also provides a renderless component version via the @vueuse/components package. Learn more about the usage.

<UseMouse v-slot="{ x, y }">
  x: {{ x }}
  y: {{ y }}
</UseMouse>
