Here's how you could create custom error classes in Node.js using latest ES6 / ES2015 syntax.
I've tried to make it as lean and unobtrusive as possible.
errors/AppError.js
var db = mongoose.connect('mongodb://localhost:27017/DB'); | |
// In middleware | |
app.use(function (req, res, next) { | |
// action after response | |
var afterResponse = function() { | |
logger.info({req: req}, "End request"); | |
// any other clean ups |
class EventEmitter | |
/// Shared Instance. | |
public static var sharedInstance = EventEmitter() | |
// ReactNativeEventEmitter is instantiated by React Native with the bridge. | |
private static var eventEmitter: ReactNativeEventEmitter! | |
private init() {} |
/* | |
In the node.js intro tutorial (http://nodejs.org/), they show a basic tcp | |
server, but for some reason omit a client connecting to it. I added an | |
example at the bottom. | |
Save the following server in example.js: | |
*/ | |
var net = require('net'); |
When hosting our web applications, we often have one public IP
address (i.e., an IP address visible to the outside world)
using which we want to host multiple web apps. For example, one
may wants to host three different web apps respectively for
example1.com
, example2.com
, and example1.com/images
on
the same machine using a single IP address.
How can we do that? Well, the good news is Internet browsers
