# The Static Web is here
The Static Web is __blisteringly fast__. The Static Web is __ultra efficient__. The Static Web is __cutting edge__. And now it has a hero.
```coffeescript
rack = require 'asset-rack'
```The Static Web is an incredibly modern, high-performance platform for delivering apps and services. But before you dive-in, you need to start with the basics. You need to understand the fundamental building block of the static web, the __asset__.
## What is an Asset?
> __An asset is a resource on the web that has the following three features:__
1. __Location (URL)__: Where on the web the resource is located.
2. __Contents (HTTP Response Body)__: The body of the response received by a web client.
3. __Meta Data (HTTP Headers)__: Gives information about the resource, like content-type, caching info.This simple definition is the theoretical bedrock of this entire framework.
## Getting Started
Let's look at a simple example.
```js
asset = new rack.Asset({
url: '/hello.txt',
contents: 'hello world'
})
```Need to serve that asset with a blisteringly fast in memory cache using express?
```
app.use(asset)
```### Hash for speed and efficiency
What's cool is that this new asset is available both here:
```
/hello.txt
```And here
```
/hello-5eb63bbbe01eeed093cb22bb8f5acdc3.txt
```That long string of letters and numbers is the md5 hash of the contents. If you hit the hash url, then we automatically set the HTTP cache to __never expire__.
Now proxies, browsers, cloud storage, content delivery networks only need to download your asset one single time. You have versioning, conflict resolution all in one simple mechanism. You can update your entire entire app instantaneously. Fast, efficient, static.
### One Rack to rule them All
Assets need to be managed. Enter the Rack. A Rack serializes your assets, allows you to deploy to the cloud, and reference urls and tags in your templates.
Say you have a directory structure like this:
```
/static # all your images, fonts, etc.
/style.less # a less files with your styles
```You can create a Rack to put all your assets in.
```js
assets = new rack.Rack([
new rack.StaticAssets({
urlPrefix: '/static',
dirname: __dirname + '/static'
}),
new rack.LessAsset({
url: '/style.css',
filename: __dirname + '/style.less'
})
])
```### Use in your Templates
After you hook into express, you can reference your assets in your server side templates.
```js
assets.tag('/style.css')
```Which gives you the html tag.
```html
```
Or you can grab just the url.
```js
assets.url('/logo.png')
```Which gives the hashed url.
```
/logo-34t90j0re9g034o4f3o4f3.png
```# Batteries Included
We have some professional grade assets included.
#### For Javascript
* [Browserify](https://github.com/techpines/asset-rack/tree/master/lib#browserifyasset-jscoffeescript) - Create browserify assets that allow you to use "node-style" requires on the client-side.
* [Snockets](https://github.com/techpines/asset-rack/tree/master/lib#snocketsasset-jscoffeescript) - Create snockets assets, to get the node-flavor of the "sprockets" from rails.#### For Stylesheets
* [Less](http://github.com/techpines/asset-rack/tree/master/lib#lessasset) - Compile less assets, ability to use dependencies, minification.
* [Stylus](https://github.com/techpines/asset-rack/tree/master/lib#stylusasset) - Compile stylu assets, ability to use dependencies, minification.#### Templates
* [Jade](https://github.com/techpines/asset-rack/tree/master/lib#jadeasset) - High, performance jade templates precompiled for the browser.
* [AngularTemplates](https://github.com/techpines/asset-rack/tree/master/lib#angulartemplatesasset) - AngularJS templates for you AngularJS folks.#### Other
* [StaticAssets](https://github.com/techpines/asset-rack/tree/master/lib#staticassets) - Images(png, jpg, gif), fonts, whatever you got.
* [DynamicAssets](https://github.com/techpines/asset-rack/tree/master/lib#dynamicassets) - For compiling file-based assets like Less or Stylus in an entire directory.## Roll your own
Asset Rack is extremely flexible. Extend the __Asset__ class and override the __create__ method to roll your own awesomeness, and watch them get automatically ka-pow'ed by your rack.
```js
SuperCoolAsset = rack.Asset.extend({
create: function(options) {
this.contents = 'easy, easy',
this.emit 'created',
}
})
```
Or, for those with more refined taste:```coffee
class SuperCoolAsset extends rack.Asset
create: (options) ->
@contents = 'even easier with coffee'
@emit 'created'
```Checkout the [tutorial.](https://github.com/techpines/asset-rack/tree/master/lib#extending-the-asset-class)
## Deploying to the Cloud
Your assets need to be deployed! Here are the current providers that are supported.### Amazon S3
```js
assets.deploy({
provider: 'amazon',
container: 'some-bucket',
accessKey: 'aws-access-key',
secretKey: 'aws-secret-key',
}, function(error) {})
```### Rackspace Cloud Files
```js
assets.deploy(
provider: 'rackspace',
container: 'some-container',
username: 'rackspace-username',
apiKey: 'rackspace-api-key',
}, function(error) {})
```### Azure Storage
```js
assets.deploy(
provider: 'azure',
container: 'some-container',
storageAccount: 'test-storage-account',
storageAccessKey: 'test-storage-access-key'
}, function(error) {})
```### Running in Production Mode
If you provide the options `configFile` in your deploy options then a config file will be written:
```js
assets.deploy(
configFile: __dirname + '/rack.json',
provider: 'amazon',
container: ...
)
```Then you can create your assets from the file like this:
```js
assets = rack.fromConfigFile({
configFile: __dirname + '/rack.json',
hostname: 'cdn.example.com'
});
app.use(assets);
```And now all of your server side templates will reference your CDN. Also, if you do happen to hit one of your static urls on the server, then you will be redirected to the CDN.
## FAQ
#### __Why is this better than Connect-Assets?__
That's easy!
* It works with node.js multi-process and cluster.
* More built-in assets.
* Un-opionated, connect-assets dictates your url structure AND directory structure.
* Ability to deploy to the cloud.
* Easy to extend.
* Simpler to use.With all that said, much thanks to Trevor for writing connect-assets.
#### __Why is this better than Grunt?__
Grunt is a great build tool. Asset Rack is not a build a tool. It never writes files to disk, there is no "build step". Everything happens "just in time".
If you have "genuine" build issues, then by all means use Grunt. You can even use Grunt with Asset Rack.
However, if you are only using Grunt to manage your static assets, then you should consider upgrading to Asset Rack.
#### __Why is this better than Wintersmith(Blacksmith)?__
Asset Rack is a static web framework, and at it's core there are only two abstractions, the `Asset` and `Rack` classes. Wintersmith is a high level framework that solves a more specific problem.
Wintersmith could consume Asset Rack as a dependency, and if something more high-level fits your specific use case, then by all means that is probably a good fit. If you need more flexibilty and power, then go with Asset Rack.
# Changelog
### 2.2.1
* A few small tweaks.
### 2.2.0
* Watch and asset recreation is now working. This should be considered experimental for this version.
```js
new StylusAsset({
watch: true,
...
});
```* Gzip is here finally.
```js
new BrowserifyAsset({
gzip: true,
...
});
```* Now adding sub assets to an asset is much simpler, just use `addAsset`.
```js
this.addAsset(asset);
this.emit('created');
```Thanks @moellenbeck, @d1plo1d, @undashes, and @noc7c9 for contributing!
### 2.1.4
* @vicapow Better error handling for `LessAsset`.
### 2.1.3
* @noc7c9 Added generalized `rack.util.walk` function, need to document the function.
* @noc7c9 Added `DynamicAssets` class.
* @noc7c9 is awesome.### 2.1.2
* Added ability to configure Stylus, thanks to @noc7c9.
```coffee
new StylusAsset
url: '/style.css'
filename: __dirname + '/style/fun.styl'
config: ->
@use bootstrap()
@define 'setting', 90
```And for javascript:
```js
new StylusAsset({
url: '/style.css',
filename: __dirname + '/style/fun.styl',
config: function (stylus) {
stylus // using "this" here seems a little unnatural
.use(bootstrap())
.define('setting', 90);
}
});
```# Test
Testing is easy and fun!
```js
cd asset-rack
npm install
npm test
