gulp-js-wrapper

Easily encapsulate js files. Good for minification or to prevent leaking variables to the window.

npm install gulp-js-wrapper

#Example

var gulp    = require('gulp'),
    jswrap = require('gulp-js-wrapper');

gulp.src('test.js')
    .pipe(jswrap({
        // pass a safe undefined into the encapsulation
        safeUndef: true,
        globals: {
            // key will be the argument
            // value will be the parameter
            'window': 'root'
        }
    }))
    .pipe(gulp.dest('./build/'));

#Options

opener

Type : [String]

The string to use as the opener. By default, this is ;(function({params}){. {params} will be replaced by the parameters from globals and safeUndef.

closer

Type : [String]

The string to use as the closer. By default, this is }({args})). {args} will be replaced by the arguments from globals.

safeUndef

Type : [Boolean]

Whether to include a safe undefined in the parameters.

;(function(undefined) {

    // typeof undefined === 'undefined'

}());

globals

Type : [Object]

An argument: 'parameter' object to use to construct the encapsulation. Keys from the object will be used as arguments and the values as parameters. For example, passing { 'window': 'root' } will result in:

;(function(root) {

    // root === window

}(window));
