## Usage
In previous versions of the AWS SDK for JavaScript v3, the AWS SDK user agent header was provided by parsing the navigator user agent string with the `bowser` library.
This was later changed to browser feature detection using the native Navigator APIs, but if you would like to have the previous functionality, use the following code:
```js
import { createUserAgentStringParsingProvider } from "@aws-sdk/util-user-agent-browser";
import { S3Client } from "@aws-sdk/client-s3";
import pkgInfo from "@aws-sdk/client-s3/package.json";
// or any other client.
const client = new S3Client({
defaultUserAgentProvider: createUserAgentStringParsingProvider({
// For a client's serviceId, check the corresponding shared runtimeConfig file
// https://github.com/aws/aws-sdk-js-v3/blob/main/clients/client-s3/src/runtimeConfig.shared.ts
serviceId: "S3",
clientVersion: pkgInfo.version,
}),
});
```
This usage is not recommended, due to the size of the additional parsing library.
