    <p>Does anyone has experience to have Node.js and socket.io working on Cloud9 IDE?</p> <p>The "Example (NodeJS with Socket.io)" (at <a href="https://c9.io/site/blog/2013/05/native-websockets-support/" rel="nofollow">https://c9.io/site/blog/2013/05/native-websockets-support/</a>) doesn't work.</p> <p>First, the server (<a href="https://c9.io/etlolap/webapp" rel="nofollow">https://c9.io/etlolap/webapp</a>, /test.js) throws an error unless I fix as follow. I clicked Run button while test.js is on active tab.</p> <pre><code>var socketIo = require('socket.io'), io = socketIo.listen(Number(process.env.PORT)); io.sockets.on('connection', function (socket) { socket.emit('news', { hello: 'world' }); socket.on('my other event', function (data) { console.log(data); }); }); </code></pre> <p>Then, my client (<a href="https://c9.io/etlolap/webapp" rel="nofollow">https://c9.io/etlolap/webapp</a>, /test.html) still cannot connect. I clicked Preview button while test.html is on active tab.</p> <pre><code>&lt;!doctype html&gt; &lt;html&gt; &lt;head&gt; &lt;script src="/socket.io/socket.io.js"&gt;&lt;/script&gt; &lt;script&gt; var socket = io.connect('https://webapp-c9-etlolap.c9.io'); socket.on('news', function (data) { console.log(data); socket.emit('my other event', { my: 'data' }); }); &lt;/script&gt; &lt;/head&gt; &lt;body&gt; Loading... &lt;/body&gt; &lt;/html&gt; </code></pre> <p>and got error message below.</p> <blockquote> <p>Failed to load resource: the server responded with a status of 404 --- (Not Found) <a href="https://c9.io/socket.io/socket.io.js" rel="nofollow">https://c9.io/socket.io/socket.io.js</a></p> <p>Uncaught ReferenceError: io is not defined --- test.html:6</p> </blockquote>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
