Node JS - Busboy retrieve parameters

Question

I'm now stuck with my project using NodeJS and Busboy. I'm trying to retrieve all the variables from my router and send it to controllers.

app.js (routes)

router.post('/product', function (req, res) {
var fields = {};
req.busboy.on('field', function(fieldname, val) {
        fields[fieldname] = val;
});
req.busboy.on('file', function (fieldname, file, filename, encoding, mimetype) {
    fields[filename] = file;
});
req.pipe(req.busboy);


productController.addNewProduct(fields, function (data) {
    res.json(data);
});
});

ProductController.js

addNewProduct: function (params, callback) {
    productLogic.addNewProduct(params, function (data) {
        callback(data);
    });
},

ProductLogic.js

addNewProduct: function (params, callback) {
    Product.findOne({ name: params.name }, function (err, product) {
        if(err) callback({ status: false, message: err });

        if(product)
            callback({ status: false, message: 'Produk sudah ada.' });

        var newProduct = new Product({
            name: params.name,
            category_id: params.category_id,
            description: params.description,
            is_active: true
        });

        newProduct.save(function (err, result) {
            if(err) callback({ status: false, message: err });

            callback({ status: true, message: result });
        });
    });
},

My goal is to process the data all at once. And now I'm not sure if I can achieve it with busboy.

Please help me on this.

Bunch of thanks in advance

You should wait for busboy to finish parsing your form before calling your method.

busboy.on('finish', function() {
  productController.addNewProduct(fields, function (data) {
    res.json(data);
  });
});

I think I already found the answer. Thanks to marton for the heads up.

I've tried:

busboy.on('finish', function() {});

but it never emitted.

The reason is I have to file.resume() in my busboy.on('file'), example:

busboy.on('file', function(fieldname, file, filename, encoding, mimetype) {
fields[fieldname] = file;
file.resume();

Once again thanks :)
