libumd - Wraps given JavaScript code with UMD


var umdify = require('libumd');


var result = umdify(js, options);

libumd doesn't guarantee pretty formatting. It is better to use something like js-beautify to deal with that.


    template: 'path to template or template name', // defaults to 'umd'
    amdModuleId: 'test', // optional AMD module id. defaults to anonymous (not set)
    globalAlias: 'alias', // name of the global variable
    deps: { // dependencies
        // use default only if the module name and the variable the module will be injected with is the same
        'default': ['Foo', 'Bar'],
        // additionally define these if the module name differs from the variable with which it will be used
        // note how we can map dependencies to specific parameters
        amd: ['foo', {'lodash': '_'}],
        cjs: ['foo', 'bar']

Default Templates

The library comes with a couple of UMD variants at /templates. In addition you may use one of your own as long as it is formatted using Handlebars syntax and follows the same naming conventions as the ones provided with the project.


Make sure PhantomJS is installed and it's within your PATH. Hit npm test after that. If the UMD wrapper fails to run against the headless browser, you'll know.
