stassets

A Static Asset Compiler


Compiling is so blase. Let it just happen.

Stassets is an express middleware for keeping your browser code up to date and ready to serve at a moment’s notice. It watches your client directory structure, and performs the build steps in memory. When you ask for your files, they’ve already been compiled. Life is easy.

To start using an express server with stassets already configured, you should use Rupert.

stassets also minimizes the number of files you will transfer - it breaks the project into

.
├── index.html
├── application.js
├── templates.js
├── all.css
├── print.css
├── screen.css
├── vendors.css
└── vendors.js

And with a basic index.jade looking like

doctype html
html(ng-app="stassets.main")
    head
        title Test Fixture

        link(rel="stylesheet", href="vendors.css")

        link(rel="stylesheet", href="all.css")
        link(rel="stylesheet", href="screen.css", media="screen")
        link(rel="stylesheet", href="print.css", media="print")
body
    main

    script(src="vendors.js")
    script(src="templates.js")
    script(src="application.js")

your project is 7 files.

Usage

stassets is built as an express middleware. With the default project layout, the easiest server looks like this:

var express = require('express')
var app = express();

var stasset = require('stasset')
app.use(stasset({
    // The client directory is relative to this app.js file
    root: __dirname + "/client"
    // My vendors are loaded with bower, which is a directory up from here.
    vendors: {
        prefix: __dirname + "/../bower_components",
        // These files will be concatenated in order.
        // All this uses is angular and bootstrap, but these can grow as large
        // as you need.
        js: [ 'angular/angular.js' ],
        css: [ 'bootstrap/dist/css/*' ]
    }
}));

app.listen(8989);

Recommended Layout

Group your code by component. It looks like this:

This is the client (in browser, Angular) codebase for a medium sized project, that manages a gradebook of student programming submissions. Notice that the controllers, templates, and tests are all next to one another. Don’t drive five directories up and three over to get to a file for the same component. That’s just crazy.

Stassets understands this directory layout, but can be configured to any other layout.

This is in line with current best practices for AngularJS.

Cascading File System

stassets has the concept of a Cascading File System. By creating a similar directory structure in several root directories, stassets users can quickly and easily implement a themeing or plugin system. To generate a cascading file system, stassets joins a list of root directories with a set of file patterns. Files in each root directory matching a pattern are joined, with files in higher priority root directories overwriting those with lower priority.

Configuration

WIP These configuration options are used to extend and customize at various places. Until 1.0, these may change subtly. They will not be stable until 1.0.

root

Required. String or Array. Specifies the cascading search order for watched files. Any file matching the same path in a later root directory will override any files at that path in a prior directory. Especially useful for creating themed systems.

./index.coffee:11:        @config.root = [@config.root] unless @config.root instanceof Array

livereload

Optional. Boolean false or Object. Configure a livereload server. If not present, uses tiny-lr's default settings. If false, completely disable Live Reload. Otherwise, is passed as-is to tiny-lr's constructor.

./index.coffee:28:        unless @config.livereload is no
./index.coffee:29:            @livereload = new LR @config.livereload

scripts

Configure application script settings.

types

Optional. Array of script filename types. Files within the root folders that have a name matching *{type}.{ScriptTypes} will be loaded, in order defined in the array, to the application.js bundle. Type extensions are determined based on registered filetype handlers in ScriptWatcher.renderers[handler]. Default type list is ['main'].

./Watchers/Script.coffee:16:        @config.scripts.types = @config.scripts.types || [

compress

Optional. Boolean to run bundled application.js through Uglify.

./Watchers/Script.coffee:63:        res @minify res if @config.scripts.compress

styles

./Watchers/Style/Style.coffee:40:        if @config.vendors?.stylus?
./Watchers/Style/Style.coffee:41:            @config.vendors.stylus.map (_1)=>
./Watchers/Style/Style.coffee:42:                @config.vendors.prefix + '/' + _1
./Watchers/Style/Style.coffee:48:        .concat(@config.root.map (_1)-> "#{_1}/stylus/definitions/variables")
./Watchers/Style/Style.coffee:49:        .concat(@config.root.map (_1)-> "#{_1}/stylus/definitions/mixins")

templates

Optional. Object configuring template rendering options.

baseModule

Optional string. If present, will prefix all template module names with baseModule.

./Watchers/Template.coffee:26:    if moduleRoot = @config.templates.baseModule

vendors

vendors.prefix

./Watchers/Vendor/Vendor.coffee:15:        @config.vendors or=
./Watchers/Vendor/Vendor.coffee:18:        @config.vendors.prefix or= './'
./Watchers/Vendor/Vendor.coffee:19:        unless @config.vendors.prefix.length? and @config.vendors.prefix.map?
./Watchers/Vendor/Vendor.coffee:20:            @config.vendors.prefix = [@config.vendors.prefix]
./Watchers/Vendor/Vendor.coffee:22:        @config.root = @config.vendors.prefix
./Watchers/Vendor/Vendor.coffee:23:        @config.noRoot = true
./Watchers/Vendor/Vendor.coffee:30:        for root in @config.vendors.prefix
./Watchers/Vendor/Vendor.coffee:40:                    smResolvedPath = Path.join @config.vendors.prefix, smPath

vendors.js

vendors.jsMaps

./Watchers/Vendor/Script.coffee:7:        @config.vendors or= {}
./Watchers/Vendor/Script.coffee:8:        @config.vendors.js or= []
./Watchers/Vendor/Script.coffee:9:        @config.vendors.jsMaps or= []
./Watchers/Vendor/Script.coffee:12:    pattern: -> super @config.vendors.js
./Watchers/Vendor/Script.coffee:13:    getMaps: -> @config.vendors.jsMaps

vendors.css

vendors.cssMaps

./Watchers/Vendor/Style.coffee:7:        @config.vendors or= {}
./Watchers/Vendor/Style.coffee:8:        @config.vendors.css or= []
./Watchers/Vendor/Style.coffee:9:        @config.vendors.cssMaps or= []
./Watchers/Vendor/Style.coffee:12:    pattern: -> super @config.vendors.css
./Watchers/Vendor/Style.coffee:13:    getMaps: -> @config.vendors.cssMaps
