Transitions Apply transitions between pages and layouts with Vue or native browser View Transitions. i-ph-exclude-square-duotone

::note Nuxt leverages Vue's <Transition> component to apply transitions between pages and layouts. ::

Page transitions

You can enable page transitions to apply an automatic transition for all your pages.

export default defineNuxtConfig({
  app: {
    pageTransition: { name: 'page', mode: 'out-in' }
  },
})

::note If you are changing layouts as well as page, the page transition you set here will not run. Instead, you should set a layout transition. ::

To start adding transition between your pages, add the following CSS to your app.vue:

::code-group

<template>
  <NuxtPage />
</template>

<style>
.page-enter-active,
.page-leave-active {
  transition: all 0.4s;
}
.page-enter-from,
.page-leave-to {
  opacity: 0;
  filter: blur(1rem);
}
</style>
<template>
  <div>
    <h1>Home page</h1>
    <NuxtLink to="/about">About page</NuxtLink>
  </div>
</template>
<template>
  <div>
    <h1>About page</h1>
    <NuxtLink to="/">Home page</NuxtLink>
  </div>
</template>

::

This produces the following result when navigating between pages:

To set a different transition for a page, set the pageTransition key in definePageMeta of the page:

::code-group

<script setup lang="ts">
definePageMeta({
  pageTransition: {
    name: 'rotate'
  }
})
</script>
<template>
  <NuxtPage />
</template>

<style>
/* ... */
.rotate-enter-active,
.rotate-leave-active {
  transition: all 0.4s;
}
.rotate-enter-from,
.rotate-leave-to {
  opacity: 0;
  transform: rotate3d(1, 1, 1, 15deg);
}
</style>

::

Moving to the about page will add the 3d rotation effect:

Layout transitions

You can enable layout transitions to apply an automatic transition for all your layouts.

export default defineNuxtConfig({
  app: {
    layoutTransition: { name: 'layout', mode: 'out-in' }
  },
})

To start adding transition between your pages and layouts, add the following CSS to your app.vue:

::code-group

<template>
  <NuxtLayout>
    <NuxtPage />
  </NuxtLayout>
</template>

<style>
.layout-enter-active,
.layout-leave-active {
  transition: all 0.4s;
}
.layout-enter-from,
.layout-leave-to {
  filter: grayscale(1);
}
</style>
<template>
  <div>
    <pre>default layout</pre>
    <slot />
  </div>
</template>

<style scoped>
div {
  background-color: lightgreen;
}
</style>
<template>
  <div>
    <pre>orange layout</pre>
    <slot />
  </div>
</template>

<style scoped>
div {
  background-color: #eebb90;
  padding: 20px;
  height: 100vh;
}
</style>
<template>
  <div>
    <h1>Home page</h1>
    <NuxtLink to="/about">About page</NuxtLink>
  </div>
</template>
<script setup lang="ts">
definePageMeta({
  layout: 'orange'
})
</script>

<template>
  <div>
    <h1>About page</h1>
    <NuxtLink to="/">Home page</NuxtLink>
  </div>
</template>

::

This produces the following result when navigating between pages:

Similar to pageTransition, you can apply a custom layoutTransition to the page component using definePageMeta:

<script setup lang="ts">
definePageMeta({
  layout: 'orange',
  layoutTransition: {
    name: 'slide-in'
  }
})
</script>

Global settings

You can customize these default transition names globally using nuxt.config.

Both pageTransition and layoutTransition keys accept TransitionProps as JSON serializable values where you can pass the name, mode and other valid transition-props of the custom CSS transition.

export default defineNuxtConfig({
  app: {
    pageTransition: {
      name: 'fade',
      mode: 'out-in' // default
    },
    layoutTransition: {
      name: 'slide',
      mode: 'out-in' // default
    }
  }
})

::warning If you change the name property, you also have to rename the CSS classes accordingly. ::

To override the global transition property, use the definePageMeta to define page or layout transitions for a single Nuxt page and override any page or layout transitions that are defined globally in nuxt.config file.

<script setup lang="ts">
definePageMeta({
  pageTransition: {
    name: 'bounce',
    mode: 'out-in' // default
  }
})
</script>

Disable Transitions

pageTransition and layoutTransition can be disabled for a specific route:

<script setup lang="ts">
definePageMeta({
  pageTransition: false,
  layoutTransition: false
})
</script>

Or globally in the nuxt.config:

export default defineNuxtConfig({
  app: {
    pageTransition: false,
    layoutTransition: false
  }
})

JavaScript Hooks

For advanced use-cases, you can use JavaScript hooks to create highly dynamic and custom transitions for your Nuxt pages.

This way presents perfect use-cases for JavaScript animation libraries such as GSAP.

<script setup lang="ts">
definePageMeta({
  pageTransition: {
    name: 'custom-flip',
    mode: 'out-in',
    onBeforeEnter: (el) => {
      console.log('Before enter...')
    },
    onEnter: (el, done) => {},
    onAfterEnter: (el) => {}
  }
})
</script>

Dynamic Transitions

To apply dynamic transitions using conditional logic, you can leverage inline middleware to assign a different transition name to to.meta.pageTransition.

::code-group

<script setup lang="ts">
definePageMeta({
  pageTransition: {
    name: 'slide-right',
    mode: 'out-in'
  },
  middleware (to, from) {
    if (to.meta.pageTransition && typeof to.meta.pageTransition !== 'boolean')
      to.meta.pageTransition.name = +to.params.id > +from.params.id ? 'slide-left' : 'slide-right'
  }
})
</script>

<template>
  <h1>#{{ $route.params.id }}</h1>
</template>

<style>
.slide-left-enter-active,
.slide-left-leave-active,
.slide-right-enter-active,
.slide-right-leave-active {
  transition: all 0.2s;
}
.slide-left-enter-from {
  opacity: 0;
  transform: translate(50px, 0);
}
.slide-left-leave-to {
  opacity: 0;
  transform: translate(-50px, 0);
}
.slide-right-enter-from {
  opacity: 0;
  transform: translate(-50px, 0);
}
.slide-right-leave-to {
  opacity: 0;
  transform: translate(50px, 0);
}
</style>
<script setup lang="ts">
const route = useRoute()
const id = computed(() => Number(route.params.id || 1))
const prev = computed(() => '/' + (id.value - 1))
const next = computed(() => '/' + (id.value + 1))
</script>

<template>
  <div>
    <slot />
    <div v-if="$route.params.id">
      <NuxtLink :to="prev">⬅️</NuxtLink> |
      <NuxtLink :to="next"></NuxtLink>
    </div>
  </div>
</template>

::

The page now applies the slide-left transition when going to the next id and slide-right for the previous:

Transition with NuxtPage

When <NuxtPage /> is used in app.vue, transition-props can be passed directly as a component props to activate global transition.

<template>
  <div>
    <NuxtLayout>
      <NuxtPage :transition="{
        name: 'bounce',
        mode: 'out-in'
      }" />
    </NuxtLayout>
  </div>
</template>

::note Remember, this page transition cannot be overridden with definePageMeta on individual pages. ::

View Transitions API (experimental)

Nuxt ships with an experimental implementation of the View Transitions API (see MDN). This is an exciting new way to implement native browser transitions which (among other things) have the ability to transition between unrelated elements on different pages.

You can check a demo on https://nuxt-view-transitions.surge.sh and the source on StackBlitz.

The Nuxt integration is under active development, but can be enabled with the experimental.viewTransition option in your configuration file:

export default defineNuxtConfig({
  experimental: {
    viewTransition: true
  }
})

The possible values are: false, true, or 'always'.

If set to true, Nuxt will not apply transitions if the user's browser matches prefers-reduced-motion: reduce (recommended). If set to always, Nuxt will always apply the transition and it is up to you to respect the user's preference.

By default, view transitions are enabled for all pages, but you can set a different global default.

export default defineNuxtConfig({
  app: {
    // Disable view transitions globally, and opt-in on a per page basis
    viewTransition: false
  },
})

It is possible to override the default viewTransition value for a page by setting the viewTransition key in definePageMeta of the page:

<script setup lang="ts">
definePageMeta({
  viewTransition: false
})
</script>

::alert{type="warning"} Overriding view transitions on a per-page basis will only have an effect if you have enabled the experimental.viewTransition option. ::

If you are also using Vue transitions like pageTransition and layoutTransition (see above) to achieve the same result as the new View Transitions API, then you may wish to disable Vue transitions if the user's browser supports the newer, native web API. You can do this by creating ~/middleware/disable-vue-transitions.global.ts with the following contents:

export default defineNuxtRouteMiddleware(to => {
  if (import.meta.server || !document.startViewTransition) { return }

  // Disable built-in Vue transitions
  to.meta.pageTransition = false
  to.meta.layoutTransition = false
})

Known issues

  • View transitions may not work as expected with nested pages/layouts/async components owing to this upstream Vue bug: https://github.com/vuejs/core/issues/5513. If you make use of this pattern, you may need to delay adopting this experimental feature or implement it yourself. Feedback is very welcome.

  • If you perform data fetching within your page setup functions, that you may wish to reconsider using this feature for the moment. (By design, View Transitions completely freeze DOM updates whilst they are taking place.) We're looking at restrict the View Transition to the final moments before <Suspense> resolves, but in the interim you may want to consider carefully whether to adopt this feature if this describes you.
