This node library implements a very simple diff algorithm for javascript/json objects.
An example diff object looks like:
> objdiff({a:2,c:1},{b:2,c:2})
{ a:
{ '$changed': true,
'-': 2 },
c:
{ '$changed': true,
'-': 1,
'+': 2 },
b:
{ '$changed': true,
'+': 2 } }
every value, that has changed is represented by an object with the key-value
pair $changed: true.
# npm install objdiff
# git clone git://github.com/Gottox/node-objdiff.git
# cd node-objdiff
# make build
This compiles a browserbuild version to dist/objdiff
var objdiff = require('objdiff').objdiff
objdiff({a:1}, {b:2});<!DOCTYPE html>
