grunt-umd

Grunt task to surround JavaScript code with the universal module definition.

Usage

Install this grunt plugin next to your project's grunt.js gruntfile with: npm install grunt-umd

Add the following line to your project's grunt.js gruntfile:

grunt.loadNpmTasks('grunt-umd');

Then configure the task:

grunt.initConfig({
    umd: {
        all: {
            options: {
                src: 'path/to/input.js',
                dest: 'path/to/output.js', // optional, if missing the src will be used
                template: 'path/to/template.hbs', // optional, a template from templates subdir
                    // can be specified by name (e.g. 'umd'); if missing, the templates/umd.hbs
                    // file will be used from [libumd](https://github.com/bebraw/libumd)
                objectToExport: 'library', // optional, internal object that will be exported
                amdModuleId: 'id', // optional, if missing the AMD module will be anonymous
                globalAlias: 'alias', // optional, changes the name of the global variable
                deps: { // optional, `default` is used as a fallback for rest!
                    'default': ['foo', 'bar'],
                    amd: ['foobar', 'barbar'],
                    cjs: ['foo', 'barbar'],
                    global: ['foobar', {depName: 'param'}]
                }
            }
        }
    }
});

And finally use it:

grunt umd:all

Note! If you want to indent the output, consider using some other plugin for that. The output grunt-umd gives is functional but not entirely aesthetic.

Templates

The following predefined Handlebars-templates are available:

• umd - the default template; the template is based on umd/returnExports.js
• unit - the template that can be helpful to wrap standalone CommonJS/Node modules; it is slightly modified version of umd template; if objectToExport option is not specified then module.exports value will be used by default

The template that should be applied can be specified by template option (e.g. 'umd' or 'unit'). You can create and use your own template (see predefined templates for examples). The path to the template file should be set relative to Gruntfile.

Demo

1. Install dependencies - npm install
2. Go to demo - cd demo
3. Go to some demo directory - cd <demo directory>
4. Execute demo - grunt

You should see some /output after this. Study Gruntfile.js to understand how it generates.
