cushion

A Cushion object. Required.

(character) One of longpoll (default), continuous, or eventsource. See Details.

(integer) Number of seconds until CouchDB closes the connection. Default: 60.

heartbeat

(logical) Whether CouchDB will send a newline character on timeout. Default: TRUE

...

Curl args passed on to one of the HTTP verbs (e.g,. GET, POST, PUT, etc.)

Details

This may not be very appropriate for use in R, but who knows, so here it is.

Also, continuous and eventsource don't seem to work in R, unless I'm missing something.

Options for the feed parmeter:

• longpoll: Closes the connection after the first event.
• continuous: Send a line of JSON per event. Keeps the socket open until timeout.
• eventsource: Like, continuous, but sends the events in EventSource format.

Examples

## Not run: 
# (x <- Cushion$new())
# 
# db_updates(x)
# db_updates(x, feed="continuous")
# db_updates(x, feed="eventsource")
# ## End(Not run)
