Configuration

Options / Props

Vue Flow allows you to configure zoom, graph and flow behavior. Configuration can be passed either as props to the VueFlow component or as options to the useVueFlow composable.

Using Component Props

<!-- Pass configuration as props -->
<template>
  <VueFlow :default-zoom="0.5" :max-zoom="4" :min-zoom="0.1" />
</template>

Using Composable Options

<script setup>
import { useVueFlow  } from '@vue-flow/core'

useVueFlow({
  defaultZoom: 0.5,
  maxZoom: 4,
  minZoom: 0.1,
})
</script>

Updating Config

You can update the configuration at any point, either by having them bound as props or using the state values returned by useVueFlow.

Using Component Props

<script setup>
const defaultZoom = ref(1)

onMounted(() => {
  // change the default zoom value of the state
  defaultZoom.value = 1
})
</script>
<template>
  <VueFlow :default-zoom="defaultZoom" />
</template>

Using State (Composable)

<script setup>
const { defaultZoom } = useVueFlow({
  defaultZoom: 0.5,
})

onMounted(() => {
  // change the default zoom value of the state
  defaultZoom.value = 1
})
</script>
