Error in Bluemix nano.use = nano.db.use = use;

[geekosphere-net]

Just tried to include 1.3.x into my project in Bluemix and got the following stack error:

I had the same error. Logs are saying that nano object do not exist. In my case this happen cause I used wrong username. Lib nano, which is base of this library, was unable to connect so constructor returned nothing. This library assumes that everything goes ok and just keeps doing its job without checking for error there.

I'm talking about 75 line of cloudant.js rev 1.3.0.

Thanks for pointing this out. We'll take a look. We are going to reorganise this library's relationship to the Nano library to improve the way they are inter-related, but in the meantime we should check for this error condition.

In fact, looking at this a bit more closely, if call the library like this:

var Cloudant = require('cloudant');

// Initialize the library with my account.
var cloudant = Cloudant({ url: "https://myuser:mybadpassword@myaccount.cloudant.com"}, function(err, data) {
  console.log(err,data);
});

Then I get a clean value of err passed to me.

If I opt for the synchronous instantiation of the library I get a clean error too when I come to use the object for the first time:

var Cloudant = require('cloudant');

var cloudant = Cloudant({ url: "https://myuser:mybadpassword@myaccount.cloudant.com"});
var db = cloudant.db.use("mydb");
db.list(function(err, data){
   console.log(err,data);
});

Any progress on this? It is a blocker.

I notice this happening if you instantiate the library with a Cloudant URL that includes a database e.g.

var cloudant = Cloudant("https://myaccount.cloudant.com/mydb");

instead of doing

var cloudant = Cloudant("https://myaccount.cloudant.com");
var mydb = cloudant.db.use("mydb");

For the record, after setting up a new instance of cloudant on Bluemix, this is what ended up working for me:

var Cloudant = require('cloudant');
var cloudant = Cloudant({
      account: 'asdfasdf-bluemix',
      key: 'asdfdasf',
      password: 'sadfsaf'});
var cdb = cloudant.db.use("communities-dev");

The API key and password can be generated from the /permissions page on the Cloudant dashboard.
