+
+# `usePreviewMode`
+
+You can use the built-in `usePreviewMode` composable to access and control preview state in Nuxt. If the composable detects preview mode it will automatically force any updates necessary for [`useAsyncData`](/docs/api/composables/use-async-data) and [`useFetch`](/docs/api/composables/use-fetch) to rerender preview content.
+
+```js
+const { enabled, state } = usePreviewMode()
+```
+
+## Options
+
+### Custom `enable` check
+
+You can specify a custom way to enable preview mode. By default the `usePreviewMode` composable will enable preview mode if there is a `preview` param in url that is equal to `true` (for example, `http://localhost:3000?preview=true`). You can wrap the `usePreviewMode` into custom composable, to keep options consistent across usages and prevent any errors.
+
+```js
+export function useMyPreviewMode () {
+  return usePreviewMode({
+    shouldEnable: () => {
+      return !!route.query.customPreview
+    }
+  });
+}
+```
+
+### Modify default state
+
+`usePreviewMode` will try to store the value of a `token` param from url in state. You can modify this state and it will be available for all [`usePreviewMode`](/docs/api/composables/use-preview-mode) calls.
+
+```js
+const data1 = ref('data1')
+
+const { enabled, state } = usePreviewMode({
+  getState: (currentState) => {
+    return { data1, data2: 'data2' }
+  }
+})
+```
+
+::note
+The `getState` function will append returned values to current state, so be careful not to accidentally overwrite important state.
+::
+
+## Example
+
+```vue [pages/some-page.vue]
+<script setup>
+const route = useRoute()
+
+const { enabled, state } = usePreviewMode({
+  shouldEnable: () => {
+    return route.query.customPreview === 'true'
+  },
+})
+
+const { data } = await useFetch('/api/preview', {
+  query: {
+    apiKey: state.token
+  }
+})
+</script>
+
+<template>
+  <div>
+    Some base content
+
+    <p v-if="enabled">
+      Only preview content: {{ state.token }}
+
+      <br>
+
+      <button @click="enabled = false">
+        disable preview mode
