title: Version History
description: A version timeline for one key with one-click restore - driven by useFiles and the versioning plugin; restore snapshots the current bytes first.
---

Lists the saved snapshots of a key (newest first) and restores any of them. Backed by the [`versioning()`](/docs/plugins/versioning) plugin, so it needs a gateway whose `Files` instance is wrapped with it and whose `authorize` allow-lists the `versions` and `restoreVersion` operations.

```tsx
"use client";

import { demoFiles } from "@/lib/demo-files";
import { VersionHistory } from "@/registry/files-sdk/version-history/version-history";

const Example = () => {
  // A demo gateway whose `Files` instance is wrapped with the `versioning()`
  // plugin and seeded with a short edit history for `notes.txt`.
  const files = demoFiles;

  return <VersionHistory files={files} fileKey="notes.txt" />;
};

export default Example;
```

## Installation

<ComponentInstall name="version-history" />

## Usage

```tsx lineNumbers
import { useFiles } from "files-sdk/react";

import { VersionHistory } from "@/components/files-sdk/version-history";

export function History({ fileKey }: { fileKey: string }) {
  const files = useFiles({ endpoint: "/api/files" });

  return <VersionHistory files={files} fileKey={fileKey} />;
}
```

Restoring snapshots the current bytes first, so it's itself reversible — an "undo" you can undo. The gateway must expose the plugin verbs:

```ts
createFilesRouter({
  files: createFiles({ adapter, plugins: [versioning()] }),
  operations: ["versions", "restoreVersion"],
});
```
