Cradle CouchDB, What are the cradle.Connection function arguments?

Beginner Question.

Below is an example given on the Cradle CouchDB documentation: https://github.com/cloudhead/cradle

What is http://living-room.couch?

What is 5984?

new(cradle.Connection)('http://living-room.couch', 5984, {
    cache: true,
    raw: false
});

I'm trying to get info from my couchdb:

url: subdomain.mywebsite.com

node port: 12345

couchdb port: 67891

I've tried different ways to connect using the above code, but I get the below error.

What is the right way to connect?

From the same documentation that you posted a link to, but only in the code folder here in this JS file https://github.com/cloudhead/cradle/blob/master/lib/cradle.js

cradle.Connection = function Connection(/* variable args */) {
var args = Array.prototype.slice.call(arguments),
    host, port, remote, auth, options = {};

args.forEach(function (a) {
    if (typeof(a) === 'number' || (typeof(a) === 'string' && /^\d{2,5}$/.test(a))) {
        port = parseInt(a);
    } else if (typeof(a) === 'object') {
        options = a;
        host = host || options.host;
        port = port || options.port;
        auth = options.auth;
    } else {
        host = a;
    }
});

So it takes whatever parameters you give it, and slices it into an array.

What is 5984?

It's the port to connect to, as evinced by this code snippet I shared.

It accepts really three types of parameters, a port (between 2 and 5 digits in length) number, a string, and an object for configuration.

You could supply just one object and declare the parts of it as this:

new(cradle.Connection)({
  host: 'http://living-room.couch',
  port: 67891,
  cache: true,
  raw: false
});

and it would work the same
