title: Hetzner Object Storage
description: Hetzner Object Storage via the S3-compatible API. Endpoint derived from the location code (fsn1, nbg1, hel1), keys auto-loaded from HCLOUD_* env vars.
---

## Installation

`@aws-sdk/client-s3`, `@aws-sdk/s3-presigned-post`, and `@aws-sdk/s3-request-presigner` are optional peer dependencies of `files-sdk` - install alongside the SDK so the adapter's imports resolve at runtime.

```package-install
files-sdk @aws-sdk/client-s3 @aws-sdk/s3-presigned-post @aws-sdk/s3-request-presigner
```

## Usage

```ts lineNumbers
import { Files } from "files-sdk";
import { hetzner } from "files-sdk/hetzner";

const files = new Files({
  adapter: hetzner({
    bucket: "uploads",
    region: "fsn1", // or "nbg1", "hel1"
    // accessKeyId / secretAccessKey auto-loaded from
    // HCLOUD_ACCESS_KEY_ID / HCLOUD_SECRET_ACCESS_KEY
  }),
});
```

## Options

<AutoTypeTable

| Method | Status | Notes |
| --- | :-: | --- |
| `upload` | ✅ |  |
| `download` | ✅ |  |
| `delete` | ✅ |  |
| `list` | ⚠️ | The S3 list API returns no per-object `Content-Type`, so `type` is inferred from the key's extension (`application/octet-stream` when unknown). Use `head()` for the stored value. |
| `search` | ✅ |  |
| `head` | ✅ |  |
| `exists` | ✅ |  |
| `copy` | ✅ |  |
| `url` | ✅ |  |
