Is there a chance to obtain a diff between obj1 and obj2?

[brailateo]

My application need to get a diff between two different objects, obj1 and obj2 !
Is there a syntax to use it like that?
I don't have an "original object" that is modified at run-time, in order to "observe" it!
I load obj1 from a database and build obj2 from a form, and need to have the diff!
Thanks,
Teo

This would be fairly easy to add. I will provide you with a new function.

var obj1 = { FirstName:"Albert", LastName:"Hinkey" };
var obj2 = { FirstName:"Albert", LastName:"Einstein" };
var patch = jsonpatch.compare( obj1, obj2 ); // will return [{op:"replace",path:"/LastName",value:"Einstein"}]

[brailateo]

That would be great, thanks!
And it's possible that the usage pattern compare(obj1,obj2) would be more frequent!
Best regards,
Teo

Working on it right now!

I added the new method observe in branch https://github.com/Starcounter-Jack/JSON-Patch/tree/compare

Could you please test and let us know how it works for you?

[brailateo]

Yes it works! I tested it with information added, updated and deleted at various levels of an [object][Array][Array] variable!
I confirm it is working fine! Thanks a lot!
Please document the method also in the quick howto in home page of the project!
Best regards,
Teo

Great! I merged the changes to the master branch (including API description in README.md). I will bump the version number soon.
