grunt-nodeify

Convert js files to node modules by executing the code in the files and linking each function/objects created in the global scope.

/!\ Caution with the js files you pass to the task, I use vm.runInContext(code, context, [filename]) and it effectively executes the js code. I don't know how it is sandboxed, it might run dangerous code.
/!\ It is a fast coding draft

Getting Started

This plugin requires Grunt ~0.4.2

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-nodeify --save-dev

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

grunt.loadNpmTasks('grunt-nodeify');

The "nodeify" task

Overview

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

grunt.initConfig({
    nodeify:{
        ex:{
            files:[{
                src: ['fixtures/ex1.js', 'fixtures/ex2.js'],
                dest: 'node/'
            }]
        }
    }
});

Usage Examples

In this example (see unit test), nodeify will convert ex1.js and ex2.js by adding module.export and requires node instructions

fixtures/ex1.js

var ex1 = {
    p : function(){
        return 'p';
    }
};

var ex11 = function(){
    return 'ex11';
};

fixtures/ex2.js

var ex2 = {
    func: function(){
        return 'func';
    },

    p: function(){
        return ex1.p();
    }
};

var ex21 = 'ex21' + ex11();

After nodeify:

node/ex1.js

var ex1 = {
    p : function(){
        return 'p';
    }
};

var ex11 = function(){
    return 'ex11';
};
module.exports = {
    ex11: ex11,
    ex1: ex1
};

node/ex2.js

var ex11 = require("./ex1.js").ex11;
var ex1 = require("./ex1.js").ex1;

var ex2 = {
    func: function(){
        return 'func';
    },

    p: function(){
        return ex1.p();
    }
};

var ex21 = 'ex21' + ex11();
module.exports = {
    ex2: ex2,
    ex11: ex11,
    ex1: ex1,
    ex21: ex21
};

Each file of a target is linked with the others depending the order. If you don't want a file to export something, create a second target. Every object in the global scope is exported..
