Generating the library

dart_js_facade_gen lib/aws-sdk.d.ts > lib/aws_sdk.dart

Note: The committed version of this library differs from the dart_js_facade_gen output. This is necessary until is resolved.

The .min.js file

the .min.js file has been created by running UglifyJS due to Uint8List bugs with the packaged .min.js file.

Known Issues

Loading objects from the S3 API with newer versions, or the minified version of 2.4.13 of the JS library will not return a Uint8List in non-Dartium browsers.

Features and bugs

Please file feature requests and bugs at the issue tracker.
