0.1.6

Simple asset compilation middleware for Connect and Express.

Igneous helps keep asset management easy by merging groups of assets down to single files. These files can be pre/post-processed in a variety of ways, including minification, coffeescript, SASS/LESS, and client-side javascript template compilation. Igneous can also watch files and directories (including subdirectories) for changes and automatically regenerate bundles on the fly.

Note: This module is still in flux. If you plan on using this right now it might be wise to include the exact version number, as some parts of the API might change.

Installation

To install Igneous, just use npm:

npm install igneous

Usage

Igneous is Connect middleware, meaning it must be used via Connect or something that extends it, like Express.

Igneous uses a simple configuration method to define groups of assets—called "flows"—along with some pre/post-processing options:

var igneous = require('igneous');

var igneous_middleware = igneous({
	root: __dirname +'/assets/',
	minify: true,
	flows: [
		{
			route: 'scripts/application.js',
			type: 'js',
			paths: [
				'toolbar.js',
				'home.js',
				'app.coffee'
			]
		}
	]
})

After the middleware is configured, it just needs to be used:

var express = require('express');
express.use( igneous_middleware );

Client-side javascript templates can also be compiled by Igneous. Right now it's limited to just Mustache, Handlebars and jQuery templates, but as time goes on more template packages will be added. An example of a Handlebars configuration:

igneous({
	root: __dirname +'/assets',
	minify: true,
	flows: [
		route: 'templates.js',
		type: 'jst',
		base: '/templates/',
		paths: [
			'test1.jst',
			'test2.jst',
			'_partial.jst'
		],
		jst_lang: 'handlebars',
		jst_namespace: 'templates'
	]
})

These templates will be made available on the jst_namespace, with each template being associated with the string used for its path. For example, to access the template 'test1.jst' from above:

templates['test1']({ test: 'My radical template data' });

For more usage details, take a look at the examples directory!

Parameters

Igneous can be configured to run in a variety of ways. Some options, such as root, are set globally, while other options, such as route are set per flow. Other options, like minify, may be set globally and overriden on a per-flow basis.

Global Parameters

• root - (string) - The root directory to check for assets.
• minify (boolean) - Minify the assets after compilation. Defaults to false.
• watch (boolean) - Watch the flow paths for changes. Defaults to true.
• encoding (string) - The file encoding to be used for each flow. Defaults to UTF-8
• flows (array) - An array of flow configuration objects.

Flow Parameters

• route (regex/string) - The route to use for this generated file.
• type (string - "js", "css", "jst") - The type of files included in this flow.
• extensions (array - ['js','coffee','cs']) - An array of strings that represent file extensions to look for. Extensions appropriate for the type are automatically added ( ex: ['css', 'less', 'sass', 'scss'] for a type of css )
• minify (boolean) - Minify the assets after compilation. Overrides the global minify parameter.
• watch (boolean) - Watch the flow paths for changes. Overrides the global watch parameter.
• encoding (string) - The file encoding to be used for this flow. Overrides the global encoding parameter.
• jst_lang (string - "mustache", "handlebars", "jquery-tmpl") - The language to use if this is a javascript template flow.
• jst_namespace (string) - The variable name to make the compiled templates available on. Defaults to JST
• paths (array) - An array of strings representing the paths to include in this flow. These paths can be files or folders. If a folder is specified, Igneous will walk through the folder and include every file found within, including subfolders.

Tests

You can run Igenous' tests with the command npm test. These tests require Mocha to run.

Future Plans

In no specific order:

• Automatic Amazon S3 deployment
• Custom pre/post-processors
• Custom store strategies
• Additional test coverage
• Additional JST options
