copied!<p>CouchDB is not an SQL database engine. It's in the family of the "NoSQL" ones.</p> <p>You don't do select, you don't create tables, etc.</p> <p>It's completely different.</p> <p>It's actually using a REST API to work. Like, to access all the documents, you access them using an HTTP GET on the following URL: <a href="http://some.server/someDbName/_all_docs" rel="nofollow">http://some.server/someDbName/_all_docs</a></p> <p>For a more thorough introduction, I suggest looking for "CouchDB tutorial" on Google.</p> <p>You'll find good links like <a href="http://net.tutsplus.com/tutorials/getting-started-with-couchdb/" rel="nofollow">this one</a> or <a href="http://nosql.mypopescu.com/post/3767157786/couchdb-tutorial-getting-started-with-couchdb" rel="nofollow">this one</a>. (I'm not vouching for any, they just look good as an introduction.)</p> <p>To make an http request in node.js, you can use the <a href="http://nodejs.org/api/http.html#http_http_request_options_callback" rel="nofollow"><code>request</code></a> method of the built-in <code>http</code> module. A shortcut method is <code>http.get</code>, which you can use like this:</p> <pre><code>var http = require( 'http' ); http.get( 'http://some.url/with/params', function( res ) { // res has the values returned }); </code></pre> <p><strong>Edit after reading your code:</strong></p> <p>Firstly, the doc you're using if outdated. Node is at v0.8, not 0.4.</p> <p>Secondly, your <code>request = require('request')</code> must give some problems (does the module exist?). I don't think the first part is even executed.</p> <p>Thirdly, just try a GET request for now. Something like:</p> <pre><code>var http = require( 'http' ); http.get( 'http://localhost:5984/_all_dbs', function( res ) { console.log( res ); }); </code></pre> <p>See if it's working. If it is, you already know how to use couchdb ;)</p> <p>Lastly, your request at the end doesn't seem wrong. Maybe it's related to <code>require('request')</code> though, so I don't know.</p>
