proxy-clone 
ES6 Proxies based deep clone, that's way more efficient than the traditional clone implementations when dealing with big objects.
Requires node 6 or later.
Note: This is not a traditional clone(). Changes to the source object will be reflected in the clone, changes to the clone however won't modify the source.
Performance
Depending on the object size, proxy-clone can be a lot faster than naive JSON clone or the clone module from npm. The most important thing to note is that clone speed is constant, however using the cloned object is slightly slower.
JSON small x 60,036 ops/sec ±1.09% (92 runs sampled)
JSON medium x 5,919 ops/sec ±0.86% (91 runs sampled)
JSON big x 526 ops/sec ±1.20% (89 runs sampled)
JSON gigantic x 39.50 ops/sec ±1.83% (54 runs sampled)

Installation
1$ npm install proxy-clone
Stability
This module makes certain assumptions about what you do with the cloned object, and I only tested it with the operations one project required. If something behaves odly, open an issue and I'll look into it.
Example
The api is what you'd expect:
1var clone = require('proxy-clone'); 2var assert = require('assert'); 3 4var obj = { 5 foo: { 6 bar: 'baz' 7 } 8}; 9 10var cloned = clone(obj); 11assert.deepEqual(cloned, obj);
API
clone(obj)
Return a deep clone of obj.
How it works
Traditional clone implementations recursively iterate over the object and copy all the properties to a new object, which can be slow. This module instead creates an ES6 Proxy. When you change a property on the proxy, it adds it to an internal change log. When you read from the proxy, it first checks for overrides, otherwise returns the original value from the object.
Kudos
Thanks to @segmentio for letting me publish this private module that I developed while working for them.
