list

Use

If you have a special type of list with helper functions you'd like to have available, you can do that in list. The following makes it so getList resolves to array-like objects that have a completed function.

var MyList = Object.create(Array.prototype);
MyList.prototype.completed = function(){
  return this.filter(function(){ return this.completed });
};

var todosConnection = connect([
  require("can-connect/constructor/constructor"),
  require("can-connect/data/url/url")
], {
  url: "todos",
  list: function(listData, set){
    var collection = Object.create(MyList);
    Array.apply(collection, listData.data);
    collection.__listSet = set;
    return collection;
  }
});

This allows:

todosConnection.getList({}).then(function(todos){
  console.log("There are",todos.completed().length, "completed todos")
});

Notice that we added the default listSetProp (__listSet) data on the list. This is useful for other extensions.
