Graph Clone
This module offers a traversal mechanic for circular data JSON structures that allows you to clone or skip cloning on nodes and also apply optional transforms to encountered nodes.
Example usage
See test.js for best illustrating example. Below is a dead simple version but the test is more exhaustive
var w = require('graph-clone')
var stringify = require('json-stringify-safe')
var obj = {
foo: {
name: 'boris',
bar: null
}
}
obj.foo.bar = obj
var copy = w(obj, () => true, (obj, key, val) => key === 'name' ? val + '!!!' : val)
console.log(stringify(copy))
// copy = {
// foo: {
// name: 'boris!!!',
// bar: [ circular ]
// }
// }
