How to add new entry in firebase in webAPP

This is data structure on path https://code.firebaseio.com/products2

enter image description here

Now i want to add new entry on products/2586/Variants. Say entry is 112: true

I have written this function.

$scope.AddProductVariant2 = function(Product, Variant)  {
  //ProductService.AddProductVariant (Product, Variant);

  var key = Product.ProductID;
  var productRef = firebase.database().ref();
  var updates = {};
  var variant = {};
  variant[Variant.VariantID] = true;
  updates['products2/' + key + '/' + 'Variants'] = variant;
  /*
  firebase.database().ref('products2/' + key + '/' + 'Variants').set({
    variant
  });
 */

 return productRef.update(updates);
};

But it is erasing all old entries.

How to add new entry without touching old one here?

Use .update instead of .set. Set removes all previous entries.

So do ref.update(object) where object is your javscript object you're trying to insert.
