buddy

buddy(1)

buddy(1) is a build tool for js/css/html projects. It helps you manage third-party dependencies, compiles source code from higher order js/css/html languages (CoffeeScript/LiveScript/Handlebars/Stylus/Less/Jade), automatically wraps js files in module definitions, statically resolves module dependencies, and concatenates (and optionally compresses) all souces into a single file for more efficient delivery to the browser.

Current version: 0.9.1 [See Change Log below for more details]

Features

• Allows you to write js modules without the module boilerplate (similar to Node.js)
• Resolves js module dependencies automatically
• Supports lazy runtime evaluation by storing js modules as strings
• Compiles CoffeeScript, LiveScript, Handlebars, Stylus, Less, and Jade source files
• Concatenates js modules into a single file
• Runs js and css code through linters to check for syntax errors
• Watches for source changes and builds automatically
• Serves static files from specified directory on specified port
• Refreshes connected browsers after each change
• Inlines css @imports automatically
• Supports execution of a test script after each build
• Copies libraries from GitHub to your project
• Copies assets from a local destination to your project

Installation

To avoid running buddy(1) directly as a global command, and thus avoid versioning problems across different projects, it is highly recommended that you instead install the separate buddy-cli command line interface system-wide:

$ npm -g install buddy-cli

...then create a package.json file for each project, locally installing buddy as a devDependency:

{
  "name": "myproject",
  "description": "This is my web project",
  "version": "0.0.1",
  "devDependencies": {
    "buddy": "0.9.0"
  }
}

$ cd path/to/project
$ npm install

Usage

Usage: buddy [options] <command> [path/to/package.json or path/to/buddy.js or path/to/buddy.json]>

Commands:

  install [config]       install dependencies
  build [config]         build js and css sources
  watch [config]         watch js and css source files and build changes
  deploy [config]        build compressed js and css sources
  ls                     list all previously created files and directories
  clean                  remove all previously created files and directories

Options:

  -h, --help      output usage information
  -V, --version   output the version number
  -c, --compress  compress output for production deployment
  -l, --lint      check output for syntax and logic errors
  -r, --reload    reload all connected live-reload clients on file change during watch
  -s, --serve     create a webserver to serve static files during watch
  -t, --test      run test command on build completion
  -L, --lazy      convert js modules for lazy evaluation
  -v, --verbose   print all messages for debugging

Examples

Generate www/main.js by concatenating and modularizing all dependencies in src or libs/js referenced in src/main.js:

package.json
{
  "name": "myproject",
  "description": "This is my web project",
  "version": "0.0.1",
  "dependencies": {
    "browser-require": "git://github.com/popeindustries/browser-require.git"
  },
  "devDependencies": {
    "buddy": "0.9.0"
  },
  "buddy": {
    "build": {
      "js": {
        "sources": ["src", "libs/js"],
        "targets": [
          {
            "input": "src/main.js",
            "output": "www/main.js"
          }
        ]
      }
    }
  }
}

$ buddy build

Generate www/main.js with references to dependencies installed via npm, ignoring Buddy specific packages:

package.json
{
  "name": "myproject",
  "description": "This is my web project",
  "version": "0.0.1",
  "dependencies": {
    "browser-require": "git://github.com/popeindustries/browser-require.git",
    "underscore": "1.4.4"
  },
  "devDependencies": {
    "buddy": "0.9.0"
  },
  "buddy": {
    "build": {
      "js": {
        "sources": ["src", "node_modules", "!node_modules/buddy", "!node_modules/browser-require"],
        "targets": [
          {
            "input": "src/main.js",
            "output": "www/main.js"
          }
        ]
      }
    }
  }
}

$ buddy build

First compile all CoffeeScript files in libs/src/coffee, then generate www/main.js by concatenating and modularizing all dependencies referenced in 'src/main.js':

            "input": "libs/src/coffee",
            "output": "libs/js"
          },
          {
            "input": "src/main.js",
            "output": "www/main.js"
          }
        ]
      }

  "dependencies": {
    "browser-require": "git://github.com/popeindustries/browser-require.git"

            "targets": [
              {
                "input": "src/widget.js",
                "output": "www/widget.js"
              }
            ]
          }
        ]
      }
    }
  }
}

Concepts

BUILD

Project Root: The directory from which all paths resolve to. Determined by location of the configuration file.

Sources: An array of directories from which all referenced files are retrieved from. Note: A js module's id is derived from it's relative path to it's source directory.

Targets: Objects that specify the input and output files or directories for each build. Targets are built in sequence, allowing builds to be chained together. Note: A js target can also have nested child targets, ensuring that dependencies are not duplicated across related builds.

Target parameters:

• input: file or directory to build. If js (or equivalent) file, all dependencies referenced will be concatenated together for output. If directory, all compileable files will be compiled, wrapped in module definitions (js), and output to individual js/css files.

• output: file or directory to output to.

• targets: a nested target that prevents the duplication of source code with it's parent target.

• modular: a flag to prevent js files from being wrapped with a module definition.

• output_compressed: an alternate file or directory to use for compressed output.

MODULES

Each js file is wrapped in a module declaration based on the file's location. Dependencies are determined by the use of require() statements:

var lib = require('./my/lib'); // in current package
var SomeClass = require('../someclass'); // in parent package
var util = require('utils/util'); // from root package

lib.doSomething();
var something = new SomeClass();
util.log('hey');

Specifying a module's public behaviour is achieved by decorating an exports object:

var myModuleVar = 'my module';

exports.myModuleMethod = function() {
  return myModuleVar;
};

...or overwriting the exports object completely:

function MyModule() {
  this.myVar = 'my instance var';
};

MyModule.prototype.myMethod = function() {
  return this.myVar;
};

module.exports = MyModule;

Each module is provided with a module, exports, and require reference.

When require()-ing a module, keep in mind that the module id is resolved based on the following rules:

• packages begin at the root folder specified in build > js > sources:

'Users/alex/project/src/package/main.js' > 'package/main'

• uppercase filenames are converted to lowercase module ids:

'my/package/Class.js' > 'my/package/class'

See node.js modules for more info on modules.

NOTE: require boilerplate needs to be included on the page to enable module loading. It's recommended to install a library like popeindustries/browser-require.

DEPENDENCIES

Dependency resources are installed from local locations or remotely from Github.

Sources: An array of local or remote resource locations.

• destination: each group of sources will be installed to the project relative location specified.

• identifier: github username/repo identifiers are preferred, but it is also possible to use identifiers from the bower package manager: 'jquery', 'backbone', 'underscore'

• versioning: github sources can specify a version by appending @ and a npm-style symantic version: '*', '1.2.3', '1.x', '~1.2.0', '>=1.2.3'

• resources: specific resources can be specified by appending # and a list of | separated relative file or directory locations: 'username/repo#a/file/or/directory|another/file/or/directory'

Output: A file destination to concatenate and compress the source contents. The order of sources determines the content order.
