# Storybook for Vue 3

Storybook for Vue 3 is a UI development environment for your Vue 3 components.
With it, you can visualize different states of your UI components and develop them interactively.

Storybook runs outside of your app.
So you can develop UI components in isolation without worrying about app specific dependencies and requirements.

## Getting Started

```sh
cd my-vue3-app
npx sb init
```

For more information visit: [storybook.js.org](https://storybook.js.org)

Storybook also comes with a lot of [addons](https://storybook.js.org/docs/vue3/configure/storybook-addons) and a great API to customize as you wish.
You can also build a [static version](https://storybook.js.org/docs/vue3/workflows/publish-storybook) of your storybook and deploy it anywhere you want.

## Extending the Vue application

Storybook creates a [Vue 3 application](https://v3.vuejs.org/api/application-api.html#application-api) for your component preview which can be imported as `import { app } from '@storybook/vue3'`.

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` file.

For example:

```js
// .storybook/preview.js

import { app } from '@storybook/vue3';

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