Basic Responses

Returning Strings From Routes

var Route = App.router;
Route.get('/', function(req, res)
    res.send('Hello World');

Creating Custom Responses

A Response object provides a variety of methods for building HTTP responses.

res.set('Content-Type', 'text/plain');

res.status(200).send('Hello world!');

Attaching Cookies To Responses

res.cookie('name', 'value').send('Hello world!')


Returning A Redirect

res.redirect(301, '');


Views typically contain the HTML of your application and provide a convenient way of separating your controller and domain logic from your presentation logic. Views are stored in the resources/views directory.

Quorra uses Jade as its default template engine. Quorra's template implementation relies on Node's consolidate library. Hence Quorra supports all the template engines that consolidate library supports. You can configure your template engine settings in app/config/view.js configuration file.

A simple view could look something like this:

<!-- View stored in applicationRoot/resources/views/index.jade -->

extends layout

block content
  h1= title
  p Welcome to #{title}

This view may be returned to the browser like so:

Route.get('/', function(req, res)
    res.view('index', { title: 'Quorra' })

The second argument passed to res.view is an object of data that should be made available to the view.

Special Responses

Creating A JSON Response

res.json({'name': 'Steve', 'state': 'CA'});

Creating A JSONP Response

res.jsonp({'name': 'Steve', 'state': 'CA'})

By default the JSONP callback name is simply callback, however you may alter this with the jsonp callback name setting in app/config/response.js.

Creating A File Download Response

Transfer the file at path as an “attachment”, typically browsers will prompt the user for download. The Content-Disposition “filename=” parameter, aka the one that will appear in the browser dialog is set to path by default, however you may provide an override filename.

When an error has occurred or transfer is complete the optional callback fn is invoked. This method uses res.sendfile () to transfer the file., fileName, callback);'/report-12345.pdf');'/report-12345.pdf', 'report.pdf');'/report-12345.pdf', 'report.pdf', function(err){
  if (err) {
    // handle error, keep in mind the response may be partially-sent
    // so check res.headerSent
  } else {
    // decrement a download credit etc
