Storybook for Vue & Vite is a [framework](../../contribute/framework.mdx) that makes it easy to develop and test UI components in isolation for [Vue](https://vuejs.org/) applications built with [Vite](https://vitejs.dev/). It includes:

* 🏎️ Pre-bundled for performance
* 🪄 Zero config
* 🧠 Comprehensive docgen
* 💫 and more!

<If notRenderer="vue">
  <Callout variant="info">
    Storybook for Vue & Vite is only supported in [Vue](?renderer=vue) projects.
  </Callout>

  {/* End non-supported renderers */}
</If>

<If renderer="vue">
  ## Requirements

  * Vue ≥ 3
  * Vite ≥ 4.0
  * Storybook ≥ 8.0

  ## Getting started

  ### In a project without Storybook

  Follow the prompts after running this command in your Vue project's root directory:

  {/* prettier-ignore-start */}

  <CodeSnippets path="init-command.md" />

  {/* prettier-ignore-end */}

  [More on getting started with Storybook.](../install.mdx)

  ### In a project with Storybook

  This framework is designed to work with Storybook 7+. If you’re not already using v7, upgrade with this command:

  {/* prettier-ignore-start */}

  <CodeSnippets path="storybook-upgrade.md" />

  {/* prettier-ignore-end */}

  #### Automatic migration

  When running the `upgrade` command above, you should get a prompt asking you to migrate to `@storybook/vue3-vite`, which should handle everything for you. In case that auto-migration does not work for your project, refer to the manual migration below.

  #### Manual migration

  First, install the framework:

  {/* prettier-ignore-start */}

  <CodeSnippets path="vue3-vite-install.md" />

  {/* prettier-ignore-end */}

  Then, update your `.storybook/main.js|ts` to change the framework property:

  {/* prettier-ignore-start */}

  <CodeSnippets path="vue3-vite-add-framework.md" />

  {/* prettier-ignore-end */}

  ## Extending the Vue application

  Storybook creates a [Vue 3 application](https://vuejs.org/api/application.html#application-api) for your component preview. When using global custom components (`app.component`), directives (`app.directive`), extensions (`app.use`), or other application methods, you will need to configure those in the `./storybook/preview.js|ts` file.

  Therefore, Storybook provides you with a `setup` function exported from this package. This function receives your Storybook instance as a callback, which you can interact with and add your custom configuration.

  ```js title=".storybook/preview.js|ts"
  import { setup } from '@storybook/vue3';

  setup((app) => {
    app.use(MyPlugin);
    app.component('my-component', MyComponent);
    app.mixin({
      // My mixin
    });
  });
  ```

  ## Using `vue-component-meta`

  <Callout variant="info">
    `vue-component-meta` is only available in Storybook ≥ 8. It is currently an opt-in, but it will become the default in a future version of Storybook.
  </Callout>

  [`vue-component-meta`](https://github.com/vuejs/language-tools/tree/master/packages/component-meta) is a tool maintained by the Vue team that extracts metadata from Vue components. Storybook can use it to generate the [controls](../../essentials/controls.mdx) for your stories and documentation. It's a more full-featured alternative to `vue-docgen-api` and is recommended for most projects.

  If you want to use `vue-component-meta`, you can configure it in your `.storybook/main.js|ts` file:

  ```ts title=".storybook/main.ts"
  import type { StorybookConfig } from '@storybook/vue3-vite';

  const config: StorybookConfig = {
    framework: {
      name: '@storybook/vue3-vite',
      options: {
        docgen: 'vue-component-meta',
      },
    },
  };

  export default config;
  ```

  `vue-component-meta` comes with many benefits and enables more documentation features, such as:

  ### Support for multiple component types

  `vue-component-meta` supports all types of Vue components (including SFC, functional, composition/options API components) from `.vue`, `.ts`, `.tsx`, `.js`, and `.jsx` files.

  It also supports both default and named component exports.

  ### Prop description and JSDoc tag annotations

  To describe a prop, including tags, you can use JSDoc comments in your component's props definition:

  ```html title="YourComponent.vue"
  <script setup lang="ts">
    interface MyComponentProps {
      /** The name of the user */
      name: string;
      /**
       * The category of the component
       *
       * @since 8.0.0
       */
      category?: string;
    }

    withDefaults(defineProps<MyComponentProps>(), {
      category: 'Uncategorized',
    });
  </script>
  ```

  The props definition above will generate the following controls:

  ![Controls generated from props](../../_assets/get-started/vue-component-meta-prop-types-controls.png)

  ### Events types extraction

  To provide a type for an emitted event, you can use TypeScript types (including JSDoc comments) in your component's `defineEmits` call:

  ```html title="YourComponent.vue"
  <script setup lang="ts">
    type MyChangeEvent = 'change';

    interface MyEvents {
      /** Fired when item is changed */
      (event: MyChangeEvent, item?: Item): void;
      /** Fired when item is deleted */
      (event: 'delete', id: string): void;
      /** Fired when item is upserted into list */
      (e: 'upsert', id: string): void;
    }

    const emit = defineEmits<MyEvents>();
  </script>
  ```

  Which will generate the following controls:

  ![Controls generated from events](../../_assets/get-started/vue-component-meta-event-types-controls.png)

  ### Slots types extraction

  The slot types are automatically extracted from your component definition and displayed in the controls panel.

  ```html title="YourComponent.vue"
  <template>
    <slot :num="123"></slot>
    <br />
    <slot name="named" str="str"></slot>
    <br />
    <slot name="no-bind"></slot>
    <br />
    <slot name="vbind" v-bind="{ num: 123, str: 'str' }"></slot>
  </template>

  <script setup lang="ts"></script>
  ```

  If you use `defineSlots`, you can describe each slot using JSDoc comments in your component's slots definition:

  ```ts
  defineSlots<{
    /** Example description for default */
    default(props: { num: number }): any;
    /** Example description for named */
    named(props: { str: string }): any;
    /** Example description for no-bind */
    noBind(props: {}): any;
    /** Example description for vbind */
    vbind(props: { num: number; str: string }): any;
  }>();
  ```

  The definition above will generate the following controls:

  ![Controls generated from slots](../../_assets/get-started/vue-component-meta-slot-types-controls.png)

  ### Exposed properties and methods

  The properties and methods exposed by your component are automatically extracted and displayed in the [Controls](../../essentials/controls.mdx) panel.

  ```html title="YourComponent.vue"
  <script setup lang="ts">
    import { ref } from 'vue';

    const label = ref('Button');
    const count = ref(100);

    defineExpose({
      /** A label string */
      label,
      /** A count number */
      count,
    });
  </script>
  ```

  The definition above will generate the following controls:

  ![Controls generated from exposed properties and methods](../../_assets/get-started/vue-component-meta-exposed-types-controls.png)

  ### Override the default configuration

  If you're working with a project that relies on [`tsconfig references`](https://www.typescriptlang.org/docs/handbook/project-references.html) to link to other existing configuration files (e.g., `tsconfig.app.json`, `tsconfig.node.json`), we recommend that you update your [`.storybook/main.js|ts`](../../configure/index.mdx) configuration file and add the following:

  ```ts title=".storybook/main.ts"
  import type { StorybookConfig } from '@storybook/vue3-vite';

  const config: StorybookConfig = {
    framework: {
      name: '@storybook/vue3-vite',
      options: {
        docgen: {
          plugin: 'vue-component-meta',
          tsconfig: 'tsconfig.app.json',
        },
      },
    },
  };

  export default config;
  ```

  <Callout variant="info">
    This is not a limitation of Storybook, but how `vue-component-meta` works. For more information, refer to the appropriate [GitHub issue](https://github.com/vuejs/language-tools/issues/3896).
  </Callout>

  Otherwise, you might face missing component types/descriptions or unresolvable import aliases like `@/some/import`.

  ## Troubleshooting

  ### Storybook doesn't work with my Vue 2 project

  [Vue 2 entered End of Life](https://v2.vuejs.org/lts/) (EOL) on December 31st, 2023, and is no longer maintained by the Vue team. As a result, Storybook no longer supports Vue 2. We recommend you upgrade your project to Vue 3, which Storybook fully supports. If that's not an option, you can still use Storybook with Vue 2 by installing the latest version of Storybook 7 with the following command:

  {/* prettier-ignore-start */}

  <CodeSnippets path="storybook-init-v7.md" />

  {/* prettier-ignore-end */}

  ## API

  ### Options

  You can pass an options object for additional configuration if needed:

  {/* prettier-ignore-start */}

  <CodeSnippets path="vue-vite-framework-options.md" />

  {/* prettier-ignore-end */}

  #### `builder`

  Type: `Record<string, any>`

  Configure options for the [framework's builder](../../api/main-config/main-config-framework.mdx#optionsbuilder). For this framework, available options can be found in the [Vite builder docs](../../builders/vite.mdx).

  #### `docgen`

  Type: `'vue-docgen-api' | 'vue-component-meta'`

  Default: `'vue-docgen-api'`

  Since: `8.0`

  Choose which docgen tool to use when generating controls for your components. See [Using `vue-component-meta`](#using-vue-component-meta) for more information.
