Difference between $reactive(this).attach($scope) and $scope.viewModel(this)

Question

In Angular "Todo App" tutorial on official meteor.com website in constructor there's:

$scope.viewModel(this);

In "Socially" tutorial on angular-meteor.com it looks like the very same thing is achieved by:

$reactive(this).attach($scope)

What's the difference?

Answer 1

Ok, so I did some research on the subject and here is what I found out.

Regarding $reactive(this).attach($scope):

"$reactive is a service that takes care of the reactivity of your Meteor data, and updates your AngularJS code."

"This service wraps context (can be used with this or $scope) - so you can use it with any context as you wish."

Read details about it here.

Regarding $scope.viewModel(this):

It looks like it is a package, a library:

"ViewModel is a view layer for Meteor. You can think of it as Angular, Knockout, Aurelia, Vue, etc. but without the boilerplate code required to make those work."
