Cushions

Cushions? What? Since it’s couch we gotta use cushions somehow. cushions are a connection class containing all connection info to a CouchDB instance. See ?Cushion for help.

As an example, connecting to a Cloudant couch:

z <- Cushion$new(
  host = "stuff.cloudant.com",
  transport = 'https',
  port = NULL,
  user = 'foobar',
  pwd = 'things'
)

Break down of parameters:

• host: the base url, without the transport (http/https)
• path: context path that is appended to the end of the url
• transport: http or https
• port: The port to connect to. Default: 5984. For Cloudant, have to set to NULL
• user: User name for the service.
• pwd: Password for the service, if any.
• headers: headers to pass in all requests

If you call Cushion$new() with no arguments you get a cushion set up for local use on your machine, with all defaults used.

x <- Cushion$new()

Ping the server

x$ping()

Nice, it’s working.
