problem: how to send 500 if a component throws an exception

[jedwards1211]

I'm not sure I fully understand this yet, but if I do, then by the time react-dom-stream gets to a component that throws an error, a status code of 200 has already been written to the response header and it's impossible to send a 500 if an error occurs.

Is this an intractable problem? Maybe you know how other streaming servers deal with this, I don't.

Sounds like an HTTP trailer may be one option

I'll look into making a PR for this

As I know it at least doesn't work in Firefox.

https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Trailer tells it's supported in all the major browsers.

@dmitry so I was confused by that article into thinking that X-Streaming-Error was a sort of standard, but obviously it's not because I can't find it anywhere else on the web. Chrome certainly didn't show any error message when I sent it in a trailer. If only status code were a header, then it would be so easy...
