grunt-amd-tamer

This module helps you manage your AMD modules. It converts anonymous modules into named ones, allows to add shims, add namespaces to modules, concatenate them all into a single file or leave them in separate files. In a way it's similar to the RequireJS bundler, but grunt-amd-tamer allows for more fine-grained control. There is also CoffeeScript support.

Getting Started

This plugin requires Grunt ^0.4.5

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-amd-tamer --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-amd-tamer');

The "amd_tamer" task

Overview

In your project's Gruntfile, add a section named amd_tamer to the data object passed into grunt.initConfig().

grunt.initConfig({
  amd_tamer: {
    options: {
      // Task-specific options go here.
    },
    your_target: {
      // Target-specific file lists and/or options go here.
    }
  }
})

You can then call the task using grunt amd_tamer.

Usage Examples

Default Options

In this example, the default options are used to do get a bunch javascript files and set src/ as a base for all modules.

grunt.initConfig({
  amd_tamer: {
    options: {
      base: 'src/'
    },
    files: {
      'dest/file.js': ['src/**/*.js'],
    }
  }
})

Sometimes you dont' want to have all the AMD modules in one file though. Here is an example to make anonymous modules named, but leave them in separate files:

grunt.initConfig({
  amd_tamer: {
    options: {
      base: 'src/'
    },
    files: [{
      expand: true,
      cwd: 'src/',
      src: ['**/*.js']
      dest: 'tmp/'
    }]
  }
})

Advanced Options

In this example, the base options is set as well. Also, all anonymous get the test namespace. There are also some shims defined for modules that are not an AMD module.

grunt.initConfig({
  amd_tamer: {
    options: {
      base: 'src/',
      namespace: 'test',
      shim: {
        a: {
          exports: 'a.test'
        },
        b: {
          deps: ['a'],
          exports: 'b'
        }
      }
    },
    files: {
      'dest/file.js': ['src/**/*.js'],
    }
  }
})

Options

options.separator

Type: String Default value: grunt.util.linefeed

The separator between files. Usually, you don't need to change this.

options.tab

Type: String Default value: \t

Tab value which will be used for intendation.

options.normalizeIndexFile

Type: Boolean Default value: true

Mimics CommonJS behavior with index.js files. An anonymous module with index.js as its filename will resolve to its parent folder, e.g. a module named folder/index will become folder.

options.base

Type: String Default value: null

Cuts off the string provided from the module name, e.g. if src/ is provided, src/mymodule will be mymodule

options.doubleQuotes

Type: Boolean Default value: false

If set to true, generated module names and shims are wrapped in double quotes instead of single quotes.

options.namespace

Type: String Default value: null

Prepends a namespace to each module name, e.g. if test is set as the namespace, mymodule becomes test/mymodule.

options.processName

Type: Function

Allows to define a function to process module names. Keep in mind, only anonymous module are being processed, not named ones.

options.process

Type: Function

Allows to process the file after transformation

options.shim

Type: Object

Similar to RequireJS shims property. Allows to export symbols for non-AMD modules.

options.modules

Type: Object

Allows to manually define module which will be appended to the destination file.

options.sourceMap

Type: Boolean Default value: true

Generates a source map for the generated files. The source mapping URL does not get appended automatically though, you need handle that manually using options.footer.

options.blacklist

Type: Array

Module names inside the blacklist will not be transformed, only concatenated to the output file. This is especially useful if your goal is to have only a single JavaScript file in the end.

options.banner

Type: String or Function

Prepend something to the resulting file, like a copyright notice.

options.footer

Type: String or Function

Append something to the resulting file, like a source map reference.
