Using CouchDB with node.js

First, get yourself a CouchDB! You can get a free hosted CouchDB in seconds or download a binary from the Couchio downloads page.

Next, install npm because all awesome node packages are in npm :)

Node has better support for HTTP than any language I've ever worked with and coincidentally CouchDB's interface is solely accessible via HTTP. First, let's just talk to CouchDB using an HTTP library and later we'll look at some higher level abstractions.

Hey,

we are going to meet at http://co-up.de on Wednesday July 13th, 19:00.

We don't have a special talk yet, let me (@janl) know if you'd like to present anything.

In lieu of a talk, I'd suggest we'll have an open discussion round. I'm happy to answer any questions you might have around CouchDB or Couchbase.

Also, drinks afterwards!

<?php
$cb = new Couchbase;
$cb->addServer("localhost", 11211); // BC compat

$view = $cb->getView("ddocname", "viewname"); // returns Couchbase_View

$result = $view->getResult(); // returns Couchbase_ViewResult
foreach($result->rows AS $row) {
  echo $row->value;
}
