bundler

Web assets bundler for Crystal.

(Pre-alpha. API will break.)

Installation

Add this to your application's shard.yml:

dependencies:
  bundler:
    github: ruivieira/bundler

Dependencies

Minifying Javascript will depend on uglify-js. Install it with

npm install -g uglify-js

Compiling Coffeescript and Typescript will depend on the respective npm packages

npm install -g coffee-script
npm install -g typescript

Usage

require "bundler"

Create a simple Bundle

bootstrap = [
	Bundler::Js.new("assets/bootstrap/js/bootstrap.js"),
    Bundler::Css.new("assets/bootstrap/css/bootstrap.css")
]

jquery = [Bundler::Js.new(assets/"jquery-2.1.4.js")]

bundle = Bundler::Bundle.create("blog", 
   bootstrap + jquery,
   "public/js")

This will create a bundled blog.css and blog.js under public/.

Combining Bundles

Let's say your blog uses Bootstrap for layout and Prism for syntax highlighting.

bootstap = Bundler::Bundle.create("bootstrap", 
	[Bundler::Js.new("assets/bootstrap/js/bootstrap.js"),
    Bundler::Css.new("assets/bootstrap/css/bootstrap.css")],
   "public")

prism = Bundler::Bundle.create("prism", 
	[Bundler::Js.new("assets/prism.js"),
    Bundler::Css.new("assets/prism.css")],
   "prism")

You can create a blog bundle. This will output blog.css and blog.js ignoring the initial bundle's outputs.

blog = Bundler::Bundle.create("blog", bootstrap + prism, "public")
# creates public/blog.{css, js}

Minifying output

Given a mixed bundle

  assets = [
        Bundler::Js.new("test1.js"),
        Bundler::Js.new("test1.js"),
        Bundler::Tsc.new("test3.ts", "test3.js"),
        Bundler::Css.new("test4.css"),
        Bundler::Css.new("test5.css"),
        Bundler::Css.new("test4.css"),
        Bundler::Js.new("test2.js"),
        Bundler::Coffee.new("test_coffee.coffee", "test_coffee.js")]
      bundle = Bundler::Bundle.create "bundle", assets, "dest", minify_js: true
      bundle.build()

This will create bundle.css and bundle.{js, min.js}. Note that duplicate (with respect to source file name) assets will just be included once.
