# Migrating to 1.0

[storybook-addon-vis][storybook-addon-vis] 1.0 has made some major improvements over the previous version. Along with the new features, there are some breaking changes.


🗒️ [storybook-addon-vis][storybook-addon-vis] 1.0 supports Storybook 8.
For Storybook 9, please use 2.x.

⚠️ Snapshot folder structure customization has changed.

In previous version,
you can customize the snapshot folder structure with the `snapshotRootDir`, `customizeSnapshotSubpath`, and `customizeSnapshotId` options to the `storybookVis` function.

In 1.0,
the options are changed to `snapshotRootDir`, `snapshotSubpath`, and `snapshotKey`.

The biggest change is that the `snapshotKey` now only allows you to specify a string that is used at the end of the snapshot file name.
See [`vitest-plugin-vis`](https://github.com/repobuddy/visual-testing?tab=readme-ov-file#customizing-snapshot-path) for more details.

⚠️ `storybook-addon-vis/preview` is moved to `storybook-addon-vis/vitest-setup`.

In previous version,
you import the `visAnnotations` from `storybook-addon-vis/preview` and add it to your `vitest.setup.ts`, and use the `vis` object from `storybook-addon-vis/vitest-setup` to add the preset:

```ts
import * as visAnnotations from 'storybook-addon-vis/preview'
import { vis } from 'storybook-addon-vis/vitest-setup'

const project = setProjectAnnotations([
	visAnnotations, // add this
	projectAnnotations
])

vis.presets.enable()
```

In 1.0,
they are combined:

```ts
import { vis, visAnnotations } from 'storybook-addon-vis/vitest-setup'

const project = setProjectAnnotations([
	visAnnotations, // add this
	projectAnnotations
])

vis.setup()
```
