Express - Passing data to all routes

Hi is there a 'express' specific way to make some global app data available to all my routes? Or is it a case of just using an module.exports statement?

Any pointers more than welcome. Node noob - btw

You can set a global object that is also available in your layout

app.js

app.configure(function(){
  app.set('view options', {pageTitle: ''});
});

app.get('/',function(request, response){
  response.app.settings['view options'].pageTitle = 'Hello World';
  response.render('home');
});

layout.jade

!!!
html
  head
    title= pageTitle
  body!= body

You could also use a dynamic helper to pass data to all views.

app.js

// Dynamic Helpers
app.dynamicHelpers({
    appSettings: function(req, res){
        return {name:"My App", version:"0.1"};
    }
});

Now on your views you can use it like this (I used ejs on this example but it should work with jade or any other view engine):

view.ejs

<%= appSettings.name %> 
<%= appSettings.version %>

Hope this helps.

You can use app.set() in the setup portion of your app to make it available to each request. The app object is available via req.app in your routes.

Personally, I like to do an app.set('name', obj); in the setup and in the routes I access it via req.app.settings.name.
