 ## Fallback for browsers without `fetch` and `stream` support
-In browsers that don't support `fetch` and `streams`, this module will fall back to the `baseConnection` configuration. The `baseConnection` and will do a `GET` request to the `url` endpoint and expects to receive JSON data.

 Note: the stream state properties such as `streamError` or `isStreaming` are not available when falling back.
