    <p><a href="http://nodejs.org/api/modules.html#modules_module_exports" rel="noreferrer"><code>module.exports</code></a> is the object that's actually returned as the result of a <code>require</code> call.</p> <p>The <code>exports</code> variable is initially set to that same object (i.e. it's a shorthand "alias"), so in the module code you would usually write something like this:</p> <pre><code>var myFunc1 = function() { ... }; var myFunc2 = function() { ... }; exports.myFunc1 = myFunc1; exports.myFunc2 = myFunc2; </code></pre> <p>to export (or "expose") the internally scoped functions <code>myFunc1</code> and <code>myFunc2</code>.</p> <p>And in the calling code you would use:</p> <pre><code>var m = require('./mymodule'); m.myFunc1(); </code></pre> <p>where the last line shows how the result of <code>require</code> is (usually) just a plain object whose properties may be accessed.</p> <p>NB: if you overwrite <code>exports</code> then it will no longer refer to <code>module.exports</code>. So if you wish to assign a new object (or a function reference) to <code>exports</code> then you should also assign that new object to <code>module.exports</code></p> <hr> <p>It's worth noting that the name added to the <code>exports</code> object does not have to be the same as the module's internally scoped name for the value that you're adding, so you could have:</p> <pre><code>var myVeryLongInternalName = function() { ... }; exports.shortName = myVeryLongInternalName; // add other objects, functions, as required </code></pre> <p>followed by:</p> <pre><code>var m = require('./mymodule'); m.shortName(); // invokes module.myVeryLongInternalName </code></pre>

    1. COWhat if you have multiple functions in that module that you add to exports? Then how would you specify from require which function you want?

    2. COGood answer - it seems to me that 'exposes' would have been a better choice of terminology than 'exports'

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.
