dnbard/knockout.getset

Another way to bind observables for Knockout

#knockout.getset

Simple library to start using this.property = true; instead of this.property(true); for observables in Knockout.

##Installation

Install from bower:

bower install knockout-getset --save

or npm:

npm install knockout.getset --save

##Compatibility Internet Explorer 9+ and literaly anything else. For more information consult this table.

##Documentation

###Observable To define an observable you need:

var viewmodel = {}, initialValue = 1;
ko.gsObservable(viewmodel, 'observableProperty', initialValue);

Then observableProperty will be available to modification in viewModel object:

viewmodel.observableProperty = 1;
viewmodel.observableProperty; //1

viewmodel.observableProperty = 5;
viewmodel.observableProperty; //5

If you want to register your own subscriptions with gsObservable:

ko.gsObservable(viewModel, 'observableProperty', initialValue)
    .subscribe(function(newValue){
        console.log('I\'ve been changed to %s', newValue);
    });

viewmodel.observableProperty = 5;
//I've been changed to 5

###Observable Array To define an observable array you need:

ko.gsObservableArray(viewmodel, 'observableArray');

viewmodel.observableArray; //[]

###Computed To define a computed you need:

ko.gsComputed(viewmodel, 'computed', function(){
    return 'I\'m computed!';
});

viewmodel.computed; //"I'm computed!"

Example on using of computed with observables:

ko.gsObservable(viewmodel, 'name', 'Peter Griffin');

ko.gsComputed(viewmodel, 'title', function(){
    return 'Mr. ' + this.name;
});

viewmodel.title; "Mr. Peter Griffin"

viewmodel.name = 'Brian Griffin';
viewmodel.title; "Mr. Brian Griffin"

###Simple objects Since there is no observables in viewmodel then we can simply skip a 'ko.toJS' or any other unwrap routine. In example:

ko.gsObservable(viewmodel, 'name', 'Peter Griffin');

ko.gsComputed(viewmodel, 'title', function(){
    return 'Mr. ' + this.name;
});

JSON.stringify(viewmodel);
//'{ "name":"Peter Griffin", "title":"Mr. Peter Griffin" }'
