Run database migration (mongodb) with node.js

I'm looking for a node module to make mongo database migrations. So far I found mongo-migrate, but not really powerful enough. (Better than nothing but I need more, I'm used to use the Ruby migration which was really powerful!)

I found another one few weeks ago, powerful but doesn't deal with mongoDb, only with MySQL, PostGre and so on.

Do you know a module or something that could help me? I mean, I'm not the first person to want to deal with DB migrations, how do you manage that? My project will be big and I need control.

Here an example of what I did so far:

*0010-init_category_table.js*

var mongodb = require('mongodb');

exports.up = function(db, next){

    var documentName = 'category';
    var collection = mongodb.Collection(db, documentName);
    var index;
    var indexOptions;

    /**
     * Create indexes.
     */
    index = { "code": 1 };
    indexOptions = { unique: true };
    collection.ensureIndex( index, {unique: true, w: 1}, function(error, data){
        console.log(error ? error : documentName + ': [ensureIndex] ' + JSON.stringify(index) + JSON.stringify(indexOptions));
    });

    index = { "name": 1 };
    indexOptions = { unique: true };
    collection.ensureIndex( index, {unique: true, w: 1}, function(error, data){
        console.log(error ? error : documentName + ': [ensureIndex] ' + JSON.stringify(index) + JSON.stringify(indexOptions));
    });

    /**
     * Create basic data.
     */
    collection.insert({
        code: 'a',
        name: 'languageStatus'
    }, {w: 1}, function(error, data){
        console.log(error ? error : documentName + ': [insert] ' + JSON.stringify(data));
    });
    collection.insert({
        code: 'b',
        name: 'accessName'
    }, {w: 1}, function(error, data){
        console.log(error ? error : documentName + ': [insert] ' + JSON.stringify(data));
    });
    collection.insert({
        code: 'c',
        name: 'roleName'
    }, {w: 1}, function(error, data){
        console.log(error ? error : documentName + ': [insert] ' + JSON.stringify(data));
    });
    collection.insert({
        code: 'd',
        name: 'translationStatus'
    }, {w: 1}, function(error, data){
        console.log(error ? error : documentName + ': [insert] ' + JSON.stringify(data));
    });

    /**
     * Display index information.
     */
    collection.indexInformation(function(error, data){
        console.log(error ? error : documentName + ': [indexes] ' + JSON.stringify(data));
    });

    next();
};

exports.down = function(db, next){
    var documentName = 'category';
    var document = mongodb.Collection(db, documentName);

    var query = {
        $or: [
            {name: 'languageStatus'},
            {name: 'accessName'},
            {name: 'roleName'},
            {name: 'translationStatus'}
        ]
    };
    document.find(query, function(error, data){
        data.each(function(error, data){
            document.remove(data, {w: 1}, function(error, number){
                console.log(error ? error : documentName + ': [remove] (' + number + ') ' + JSON.stringify(data));
            })
        });
    });

    next();
};
