foundation 5 with compass and nodejs - node.js

Question

I am just getting started with nodejs and I'm trying to understand how everything works...and I'm getting trouble. Please forgive me in advance for the number of questions and the confusion it could generate.
What I'd like to set up is a nodejs server using express, mongodb, passeport, jade, foundation5 with sass and compass, socketio and html boilerplate.It seems to me as a "regular" project but for some reason I couldn't find any skeleton or generator like the one's yeoman provide for it. Is there a key problem with this architecture ?
If I got it correctly, compass is a set of tools for sass but if you go to the foundation website. Either you can install compass with foundation or either grunt with foundation and sass but not foundation with compass and grunt.
Is there a logic behind that ?
Another solution is to compile the sass files on the nodejs server like this:
var express = require('express'),
compass = require('node-compass'),
path = require('path'),
app = express();
app.configure(function() {
app.use(compass());
app.use('/', express.static(path.join(__dirname, 'public')));
});
app.listen(3000);
On which cases is it better to compile it on the server using a middleware such as compass or node-sass rather than using a grunt command that generate the client plain css file to be deployed ?
Thanks in advance.
Update:
I misunderstood one thing:
libsass, the C version of the popular stylesheet preprocessor, Sass.
It allows you to natively compile .scss files to css at incredible speed
At the time of writing libsass (and therefore Node-sass and therefore grunt-sass) does not support Compass.

It explains why you can rather use libsass or compass.

Answer 1

grunt command is more effective method, if you have a lot of visitors, better for you is to compile all style into css by grunt command
Middleware is more flexibility, you can change your styles on the fly, but for each user request, all styles will compile again and again. so your server will work more slowly

Answer 2

I'm using grunt with compass. Don't forget to install the grunt-contrib-compass nodes module!
npm install grunt-contrib-compass --save-dev
Here's my gruntfile.js:
module.exports = function(grunt) {
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
compass: {
dist: {
options: {
specify: 'library/scss/style.scss',
outputStyle: 'compressed',
sassDir: 'library/scss',
cssDir: 'library/css'
},
}
},
watch: {
// grunt: { files: ['Gruntfile.js'] },
css: {
// files: '**/*.scss',
files: 'library/scss/style.scss',
tasks: ['compass']
}
}
});
grunt.loadNpmTasks('grunt-contrib-compass');
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.registerTask('default',['watch']);
}
