Asset

Asset manager for lazy people (think homebrew for assets).

Installation

$ npm install -g asset

Usage

 Usage: asset [command] [options]

 Commands:

   install <name ...>   installs the given asset <name ...>
   search  [query]      search available assets with optional [query]
   info  <name ...>     display verbose information for the given asset <name ...>
   none                 install dependencies from ./assets.json

 Options:

   -c, --compress    compress assets
   -o, --out <dir>   output directory defaulting to ./public
   -V, --version     output program version
   -h, --help        display help information

Examples

Installing Several Assets

By default asset installs to ./public.

  $ asset raphael jquery

   install : raphael@1.4.7
   install : jquery@1.5.2
  download : jquery@1.5.2
  complete : jquery@1.5.2 public/jquery.js
  download : raphael@1.4.7
  complete : raphael@1.4.7 public/raphael.js

Asset names accept an optional version and modifiers, taking the form:

<name> ['@' version] [':' 'compress']

To install all assets (that support compression) as compressed, we can use the --compress flag:

  $ asset jquery raphael --compress

However this can be done at the asset-level as well using the :compress modifier:

  $ asset jquery@1.4.3:compress raphael

        install : jquery@1.4.3
        install : raphael@1.4.7
       download : jquery@1.4.3
       complete : jquery@1.4.3 public/jquery.min.js
       download : raphael@1.4.7
       complete : raphael@1.4.7 public/raphael.js

Install Destination

Tweak the output directory with -o, --out <dir>.

  $ asset raphael g.raphael g.pie -o public/javascripts

   install : raphael@1.4.7
   install : g.raphael@0.4.1
   install : g.pie@0.4.1
  download : raphael@1.4.7
  complete : raphael@1.4.7 public/javascripts/raphael.js
  download : g.raphael@0.4.1
  complete : g.raphael@0.4.1 public/javascripts/g.raphael.js
  download : g.pie@0.4.1
  complete : g.pie@0.4.1 public/javascripts/g.pie.js

Alternatively passing a directory name containing "/" will work as well, since asset knows this is not an asset, and becomes equivalent to --out <dir>:

   $ asset raphael jquery public/javascripts

Dependency Resolution

Asset currently supports extremely basic dependency mapping, for example below is the output of installing g.pie, which depends on g.raphael, which in turn depends on raphael itself.

$ asset g.pie

      install : g.pie@0.4.1
   dependency : g.raphael@0.4.1
      install : g.raphael@0.4.1
   dependency : raphael@1.4.7
      install : raphael@1.4.7
     download : raphael@1.4.7
     complete : raphael@1.4.7 public/raphael.js
     download : g.raphael@0.4.1
     complete : g.raphael@0.4.1 public/g.raphael.js
     download : g.pie@0.4.1
     complete : g.pie@0.4.1 public/g.pie.js

Asset Information

Inspect verbose asset information:

$ asset info jquery g.raphael

         name : jquery
  description : jquery core framework
          url : http://code.jquery.com/jquery-{version}.min.js
      version : 1.5.2
     filename : jquery.js

         name : g.raphael
  description : charting for raphael
          url : https://github.com/DmitryBaranovskiy/g.raphael/raw/v{version}/g.raphael-min.js
      version : 0.4.1
     filename : g.raphael.js
 dependencies : raphael

Installation Destination

To install a specific version, we can use the @ character:

  $ asset jquery@1.5.0

Search Repository

We can search the repository with an optional query, listing available assets and their default versions:

 $ asset raphael

  install : raphael@1.4.7
 download : raphael@1.4.7
 complete : raphael@1.4.7 public/raphael.js

assets.json

By adding ./assets.json you can store application dependencies, and install them quickly and easily with a single command asset. For example this file may contain one or more deps:

 {
     "g.raphael": "0.4.1"
   , "jquery": "1.5.2"
   , "modernizr": "1.7"
 }

Installed with the command:

 $ asset
 
    install : g.raphael@0.4.1
 dependency : raphael@1.4.7
    install : raphael@1.4.7
    install : jquery@1.5.2
    install : modernizr@1.7
   download : jquery@1.5.2
   complete : jquery@1.5.2 public/jquery.js
   download : raphael@1.4.7
   complete : raphael@1.4.7 public/raphael.js
   download : g.raphael@0.4.1
   complete : g.raphael@0.4.1 public/g.raphael.js
   download : modernizr@1.7
   complete : modernizr@1.7 public/modernizr.js

Configuration

By default options must be passed via the CLI, however asset will also check the ./.asset and ~/.asset JSON configuration files, so for example a project may set { "out": "public/javascripts" } if we are mainly working with javascript, however the CLI options will always take precedence.

The Repository

By default the repo bundled with asset is used, however the ~/.assets configuration file is checked first. Perhaps down the road if/when asset becomes more flexible a repo will be hosted, for now simply fork the project edit ./assets.json, and send a pull request.
