    <p>I'm using the ExpressJS web framework for NodeJS.</p> <p>People using ExpressJS put their environments (development, production, test...), their routes etc on the <code>app.js</code>. I think that it's not a beautiful way because when you have a big application, app.js is too big!</p> <p>I would like to have this directory structure:</p> <pre><code>| my-application | -- app.js | -- config/ | -- environment.js | -- routes.js </code></pre> <p>Here's my code:</p> <p><strong>app.js</strong></p> <pre><code>var express = require('express'); var app = module.exports = express.createServer(); require('./config/environment.js')(app, express); require('./config/routes.js')(app); app.listen(3000); </code></pre> <p><strong>config/environment.js</strong></p> <pre><code>module.exports = function(app, express){ app.configure(function() { app.use(express.logger()); }); app.configure('development', function() { app.use(express.errorHandler({ dumpExceptions: true, showStack: true })); }); app.configure('production', function() { app.use(express.errorHandler()); }); }; </code></pre> <p><strong>config/routes.js</strong></p> <pre><code>module.exports = function(app) { app.get('/', function(req, res) { res.send('Hello world !'); }); }; </code></pre> <p>My code works well and I think that the structure of the directories is beautiful. However, the code had to be adapted and I'm not sure that it's good/beautiful.</p> <p>Is it better to use my structure of directories and adapt the code or simply use one file (app.js)?</p> <p>Thanks for your advices!</p>

    1. COAre the performance issues of doing it this way still lurking around? I remember reading somewhere (maybe the express group) that when you separate everything like this you lose a ton of performance. Something like your reqs/sec will drop by a noticeable amount, almost as if it were a bug.

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.
