Pound 2.0 - High-level asset management for NodeJS/Express like it should be.
Pound allows you to think of assets in terms of packages/bundles.
Pound supports Express 2 and 3 and use Bundle-Up as the underlying asset manager.
npm install pound
example/server_simple.js
var express = require('express')
, Pound = require('pound')
, bundle = pound.defineAsset; // alias
// Define where is the public directory
var pound = Pound.create({
publicDir: __dirname+'/public',
staticUrlRoot: '/'
});
// By default all bundle's assets are public (if another inherit from it, it'll get all of those assets)
bundle('home', {
// Css assets
css:[
'$css/bootstrap-responsive.0.2.4' // will resolve $js with the pound.resolve.css function
, '$css/bootstrap.0.2.4'
, '$css/font-awesome.2.0'
, '$css/global'
],
// JS assets
js:[
'$js/jquery.1.7.2' // will resolve $js with the pound.resolve.js function
, '$js/bootstrap.0.2.4'
]
});
bundle({name:'app', extend:'home'}, {
css:[
