Building the SDK for Browsers - Amazon SDK for JavaScript
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China.

The Amazon SDK for JavaScript V3 API Reference Guide describes in detail all the API operations for the Amazon SDK for JavaScript version 3 (V3).

Starting October 1, 2022, Amazon SDK for JavaScript (v3) will end support for Internet Explorer 11 (IE 11). For details, see Announcing the end of support for Internet Explorer 11 in the Amazon SDK for JavaScript (v3).

Building the SDK for Browsers

Unlike SDK for JavaScript version 2 (V2), V3 is not provided as a JavaScript file with support included for a default set of services. Instead V3 enables you to bundle and include in the browser only the SDK for JavaScript files you require, reducing overhead. We recommend using Webpack to bundle the required SDK for JavaScript files, and any additional third-party packages your require, into a single Javascript file, and load it into browser scripts using a <script> tag. For more information about Webpack, see Bundling applications with webpack. For an example that uses Webpack to load V3 SDK for JavaScript into a browser, see Build an app to submit data to DynamoDB.

If you work with the SDK outside of an environment that enforces CORS in your browser and if you want access to all services provided by the SDK for JavaScript, you can build a custom copy of the SDK locally by cloning the repository and running the same build tools that build the default hosted version of the SDK. The following sections describe the steps to build the SDK with extra services and API versions.

Using the SDK Builder to Build the SDK for JavaScript


Amazon Web Services version 3 (V3) no longer supports Browser Builder. To mimimize bandwidth usage of browser applications, we recommend you import named modules, and bundle them to reduce size. For more information about bundling, see Bundling applications with webpack.
