title: Yandex Object Storage
description: Yandex Object Storage via the S3-compatible API. Fixed global endpoint, region defaults to ru-central1, keys auto-loaded from YANDEX_* 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 { yandex } from "files-sdk/yandex";

const files = new Files({
  adapter: yandex({
    bucket: "uploads",
    // endpoint defaults to https://storage.yandexcloud.net
    // region defaults to "ru-central1"
    // accessKeyId / secretAccessKey auto-loaded from
    // YANDEX_ACCESS_KEY_ID / YANDEX_SECRET_ACCESS_KEY
  }),
});
```

Yandex Object Storage via its S3-compatible API. A thin wrapper around the S3 adapter - fixed global endpoint, region defaults to `"ru-central1"` for signing, virtual-hosted-style addressing, errors relabelled. Auto-loads from `YANDEX_ACCESS_KEY_ID` and `YANDEX_SECRET_ACCESS_KEY`. Generate static access keys in the Yandex Cloud console for a service account with the `storage.editor` role.

## Compatibility

| 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` | ✅ |  |
| `signedUploadUrl` | ✅ |  |
