Implement streaming in the browser

The current use of chunked transfer encoding is based on xhr.responseText. There are now more efficient methods available for Firefox (moz-chunked-text) and Chrome (ReadableByteStream). Would there be any interest in using those methods when possible?

It would be awesome if superagent supported streaming in the browser along the lines of what this library offers. I’d be willing to contribute if there’s any interest.

fetch() is a thing now and it works well with streaming, so if you need streams, use fetch().

If you get error in XmlHTTPRequest then there’s nothing we can do. The browser would report the same error via streaming API too, and stop streaming early.

It’s most likely that it’s a problem outside of browser, e.g. in your CDN, your reverse proxy, your web server, or middleware managing node.
