# AWS SDK for JavaScript v3
## Package Structure
- `@aws-sdk/client-*` — one per service, generated by [smithy-typescript](https://github.com/awslabs/smithy-typescript); one-to-one with AWS services and operations
- `@aws-sdk/lib-*` — higher-level helpers (e.g. `lib-dynamodb`, `lib-storage`)
- `@aws-sdk/*` (no prefix) — utility packages (mostly internal; don't import deep paths)
Always import from the package root:
```js
import { S3Client } from "@aws-sdk/client-s3"; // correct
