Note: Our new official nodejs driver is arangojs. You also can look at this blogpost about the new driver.
We got a note from Anders Elo from Sweden. He told us that he has released a ArangoDB client for node.js. Awesome! 🙂 You can find it on Github under the URL https://github.com/kaerus/arango-client. To install locally

npm install git://github.com/kaerus/arango-client |
Anders also writes:
- It’s still lacking features and is prone to changes but it works quite nice, atleast I think so. 🙂 I’ve not documented this project as of yet due to lack of time so I’ll briefly instruct you by some examples.*

var arango = require('arango.client'), util = require('util'); /* Prepare a connection, defaults {protocol:'http', hostname:'127.0.0.1', port: 8529} */ db = new arango.Connection({name:"testcollection"}); /* we need to first create our test collection */ db.collection.create(function(err,ret){ console.log("err(%s): ",err, ret); }); /* create a new document in collection */ db.document.create({a:"test"},function(err,ret){ if(err) console.log("error(%s): ", err,ret); else console.log(util.inspect(ret)); }); /* create a document and a new collection on demand */ db.document.create(true,"newcollection",{a:"test"},function(err,ret){ if(err) console.log("error(%s): ", err,ret); else console.log(util.inspect(ret)); }); /* alternate style utilizing events */ db.document.list().on('result',function(result){ console.log(util.inspect(result)); }).on('error',function(error){ console.log("error(%s):", error.code, error.message); }); |
The interface to the ArangoDB REST api resides in the lib/api directory. You can find out more details there. Anders also includes some tests, just runt “npm test” to execute them.

I am trying to include this on a intellij project. I get this error.
db.document.create_(“newcollection”,{a:”test”},function(err,ret){

If I change the _create to create, I get the below message
error(404): collection /_api/collection/newcollection not found
I am kinda new to all this. Really appreciate any pointers.

The api for “on demand collections” has changed, I have updated the example. Hint: Anders includes many examples in the test directory of the module 🙂
I have installed the latest node module.
Here is the version info
“name”: “arango.client”,
“version”: “0.6.2”,
I looked at the test folder ..
https://github.com/kaerus-component/arango/blob/master/test/arango.js
I see the below definition…
var libs = [
‘../lib/arango’,
‘./lib/qunit-1.10.js’
];
I dont see a relative folder ../lib/arango.
And when I try to run this .. I get
$ node arango.js
/Users/shekart/WebstormProjects/byeh_new/node_modules/arango.client/test/arango.js:11
module = QUnit.module;
^
ReferenceError: QUnit is not defined
I am sorry if I am posting trivial questions but I really appreciate any help.

to run the tests on a fresh node installation in the current version of arango.client I had to install two additional modules, qunit and amdefine via
sudo npm install amdefine
sudo npm install qunit
I have installed both qunit and amdefine.
I still see the same error.

Here is what I see on node_modules folder ..
$ pwd
/Users/shekart/WebstormProjects/byeh_new/node_modules
$ ls
amdefine arango.client express jade qunit
Here is what I see on node_modules folder ..
$ pwd
/Users/shekart/WebstormProjects/byeh_new/node_modules
$ ls
amdefine arango.client express jade qunit
I have installed both qunit and amdefine.
I still see the same error.

I wrote something in the Google Group (this is a bit more comfortable than the comment’s section :-))
Disqus –
I think I got over some hiccups :).
I believe we need var QUnit = require(‘qunit’);
I now have new set of error:
/usr/local/bin/node collection.js

I tried to precede it with function asyncTest(..
I then get a different error ..

^^^^^^^^

Any idea on whats going on?
