# @aws-sdk/util-user-agent-browser [](https://www.npmjs.com/package/@aws-sdk/util-user-agent-browser) [](https://www.npmjs.com/package/@aws-sdk/util-user-agent-browser) ## 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.
