copied!<p>I did some research on this and I would do it like this.</p> <h1>Setup</h1> <h2>beanstalkd</h2> <ol> <li><p>Install <a href="http://kr.github.com/beanstalkd/" rel="noreferrer">beanstalkd</a>. Another message queue, <strong>BUT</strong> this one supports <a href="https://github.com/kr/beanstalkd/blob/master/doc/protocol.txt" rel="noreferrer">DELAYED PUTS</a>. If you compile from source it is going to be a little harder because it depends on <a href="http://monkey.org/~provos/libevent/" rel="noreferrer">libevent</a>(like memcached). But then again, I don't think you have to compile it from source, because there are a lot of <a href="http://kr.github.com/beanstalkd/download.html" rel="noreferrer">binary packages</a> available. For example on Ubuntu you can install beanstalkd by issuing the command:</p> <p><code>sudo apt-get install beanstalkd</code></p></li> </ol> <h2>node-beanstalk-client</h2> <ol start="2"> <li><p>Install a beanstalkd client library. The best one I found was <a href="https://github.com/benlund/node-beanstalk-client" rel="noreferrer">node-beanstalk-client</a>. Because on the beanstalkd client library list this library isn't/wasn't mentioned(Then again I can add entries to the list, so I will add this one). The reasons I prefer this library over the others are:</p> <ol> <li><strong>Npm package</strong>: I liked to use a npm package to install client library. The others did not have any.</li> <li><strong>Active development</strong>: I prefer libraries which have later/more commits.</li> </ol></li> </ol> <p>So to install it, after you have installed <a href="https://github.com/isaacs/npm" rel="noreferrer">npm</a>(<a href="https://gist.github.com/579814" rel="noreferrer">the write way</a>) you would just issue the following command:</p> <pre><code>npm install beanstalk_client </code></pre> <h1>Code</h1> <h2>consumer.js</h2> <pre><code>var client = require('beanstalk_client').Client; client.connect('127.0.0.1:11300', function(err, conn) { var reserve = function() { conn.reserve(function(err, job_id, job_json) { console.log('got job: ' + job_id); console.log('got job data: ' + job_json); console.log('module name is ' + JSON.parse(job_json).data.name); conn.destroy(job_id, function(err) { console.log('destroyed job'); reserve(); }); }); } reserve(); }); </code></pre> <p>First start the consumer: </p> <pre><code>node consumer.js </code></pre> <p>Next start <code>producer.js</code>. Five seconds(delay I specified) after you execute <code>producer.js</code>, <code>consumer.js</code> will process the message.</p> <h2>producer.js</h2> <pre><code>var client = require('beanstalk_client').Client; client.connect('127.0.0.1:11300', function(err, conn) { var job_data = {"data": {"name": "node-beanstalk-client"}}; var priority = 0; var delay = 5; var timeToRun = 1; conn.put(priority, delay, timeToRun, JSON.stringify(job_data), function(err, job_id) { console.log('put job: ' + job_id); process.exit(); }); }); </code></pre> <p>to start just issue:</p> <pre><code>node producer.js </code></pre>
