Node.js - Run a module if it is not `required`
In node, you can tell your program to do two different things depending on whether the code is run from require('./something.js') or node something.js. This is useful if you want to interact with one of your modules independently.
if (!module.parent) {
// ran with `node something.js`
app.listen(8088, function() {
console.log('app listening on port 8088');
})
} else {
// used with `require('/.something.js')`
module.exports = app;
}
See the documentation for modules for more info.
