Subject [jira] Commented: (COUCHDB-841) Support WebSockets in continuous changes feeds
Date Mon, 14 Mar 2011 20:21:30 GMT


Dirkjan Ochtman commented on COUCHDB-841:

I agree that the time to do this probably hasn't exactly arrived yet; it would make more sense
to wait until the protocol has been finalized. Which as far as I gather should be close except
for the security issue in the recent version. On the other hand, I think the caniuse-report
is looking rather promising, with websockets available in all of the modern browsers (Firefox
4, Chrome, Safari, Opera -- I don't think we can count IE9 as fully modern yet). We've started
using it at work, and it seems to work wonderfully in both Firefox 4 and Chrome (although
I had to enable it in Firefox to circumvent the security protection). So I think this would
be great to do, but it would make sense to wait until the security bugs have been ironed out
of the protocol.

It would also need someone to step up and make this happen in mochiweb, AFAICT.

> Just wanted to put this on the roadmap: it would be nice if continuous changes feeds
(and maybe some other things in CouchDB, not sure) could support WebSockets. WebSockets are
an emerging standard (there's no final spec yet) with implementations in both recent Chrome
and Firefox (beta) releases that allows servers to push information to the browser without
having to do polling (or longpolling).
