Recursive Object Observer
This helps and reports back for any changes that may happen to an object, reports back the path
and the value
it has changed into.
This is a coffee script atm (as it's only first draft)
#testing
The tests are failing because Object.observe
is not defined in phantom when tests run.
If you know how to run tests you can change the PhantomJS
to Chrome
on the package manager under scripts.test
to test it locally. then you can run it with npm test
on you CLI
npm test
#how it works
parson = {name: "Tom", age: 18}
new Observe( person , function (changes, original){
console.log(changes);
} )
person.name = "Ben"; // {value: "Ben", path: name}
person.age = 20; // {value: 20, path: 'age'}
This should also work for recursive, and future ancestors which are added into the object.
person.children = [{name:"Joe"} , {name: "Kim"} , {name:"Tom"} ]
person.children[1].name = 'ana'; //{value: "ana", path: 'children[1].name'}
This object is especially useful when binding (one way or two-way) to listen for changes taking advantage of the native Object.observe(obj, callback)
aka O.o
in a recursive mode, therefore performance should be optimal.
Raise a ticket if you would like to contribute.
#What is the original parameter?
This is the default changes, which the native Object.observe
uses, if you would rather use the native so be it :), this has a more details information of what has happened to a particular object, however it may be tricky when working with deep objects.
