Socket.IO and Heroku

jmendeth edited this page · 6 revisions

Heroku and Socket.IO do not play well out of the box with each other.
To fix this, Socket.IO must have its transport set to XHR-polling with a 10 second interval:

io.set('transports', ['xhr-polling']);
io.set('polling duration', 10);

See this Heroku article for more information.

Something went wrong with that request. Please try again.
