title: Google Cloud Storage
description: Google Cloud Storage via the official @google-cloud/storage SDK. Application Default Credentials by default.
peerDeps:
  - "@google-cloud/storage"
---

## Installation

`@google-cloud/storage` is an optional peer dependency of `files-sdk` - install alongside the SDK so the adapter's imports resolve at runtime.

```package-install
files-sdk @google-cloud/storage
```

## Usage

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

const files = new Files({
  adapter: gcs({
    bucket: "uploads",
    // No credentials needed in most setups - the @google-cloud/storage
    // SDK auto-discovers Application Default Credentials from
    // GOOGLE_APPLICATION_CREDENTIALS, gcloud auth, or the runtime
    // service account on Cloud Run / GKE / GCE.
  }),
});
```

`upload` reports true byte-level [progress](/api/upload#progress-tracking) via `onProgress`. Uploads default to a single simple request; when `onProgress` is passed, the adapter switches to a **resumable** upload (the only path that emits progress), which adds one round trip.

## Options
