Passing GET parameters to Express+Mongoose Restful API

I'm just getting into Node, Express, and Mongoose. Loving it so far, but can't figure out how to pass MongoDB filtering from the AJAX call to the API.

I have a simple jQuery AJAX request like this:

$.getJSON('/api/products', {
    filter: { status: 'active' } // <-- Want this to get processed by the API
}, function(products){
    console.log(products);
});

Here are the important parts of my Express + Mongoose API:

// Define Mongoose Schema
var Schema = mongoose.Schema;

// Product Schema
var ProductSchema = new Schema({
    name: { type: 'string', required: false },
    price: { type: 'number', required: false },
    status: { type: 'string', required: false },
    description: { type: 'string', required: false },
});

// Product Model
var ProductModel = mongoose.model('Product', ProductSchema);

// Product Endpoint
app.get('/api/products', function(req, res){
    return ProductModel.find(function(error, products){
        return res.send(products);
    });
});

You should be sending the encoded paramters with your request as it is. Now you just need to get them and pass it to your query:

// Product Endpoint
app.get('/api/products', function(req, res){

    var filter =  {};
    for ( var k in req.query.filter ) {
        filter[k] = req.query.filter[k];   // probably want to check in the loop
    }
    return ProductModel.find(filter, function(error, products){
        return res.send(products);
    });
});

That loop is there because you might want to check what was sent in. But I'll leave that up to you.

Also req.params if that suits your taste.
