js-traverse - Traverse and transform objects by visiting every node on a recursive walk.

•    Javascript

---

Traverse and transform objects by visiting every node on a recursive walk.Each method that takes an fn uses the context documented below in the context section.

deep-freeze - recursively Object.freeze() on objects and functions

•    Javascript

---

Call Object.freeze(obj) recursively on all unfrozen properties of obj that are functions or objects.Based in part on the code snippet from the MDN wiki page on Object.freeze(), which is released to the public domain.

deepmerge - A library for deep (recursive) merging of Javascript objects

•    Javascript

---

Merge the enumerable attributes of two objects deeply. For the old array element-merging algorithm, see the arrayMerge option below.

sort-keys - Sort the keys of an object

•    Javascript

---

Useful to get a deterministically ordered object, as the order of keys can vary between engines.Returns a new object with sorted keys.

sort object keys obj key stable deterministic deep recursive recursively

merge-defaults - A recursive version of `_.defaults`.

•    Javascript

---

Implements a deep version of _.defaults.This module DOES NOT merge arrays or dates.

map-obj - Map object keys and values into a new object

•    Javascript

---

Source object to copy properties from.Mapping function.

camelcase-keys - Convert object keys to camelCase

•    Javascript

---

Object or array of objects to camelCase.Exclude keys from being camelCased.

deep - node.js utilities for manipulating deeply-nested data structures

•    CoffeeScript

---

This library contains utilities for manipulating deeply-nested data structures. These functions only perform recursive traversal of arrays and "plain" objects, that is, those objects that were created using object literals ({}) or new Object. This function works by checking to see if the argument's constructor's name is Object.

cloner - Cloning ES5+ objects in a shallow or deep way

•    Javascript

---

An ES5+ compatible utility to deep or shallow copy and merge objects. The module has two sub modules: shallow and deep. Both of them will have two methods: copy and merge.

mux - Creates a promise that waits for the promises in nested data structures and resolves to data structures of the same form

•    Javascript

---

Creates a promise that waits for the promises in nested data structures and resolves to data structures of the same form. It recursively traverses the input data structure and multiplexes its promises.

merge-deep - Recursively merge values in a JavaScript object.

•    Javascript

---

Recursively merge values in a javascript object. Pull requests and stars are always welcome. For bugs and feature requests, please create an issue.

mixin-deep - Deeply mix the properties of objects into the first object, while also mixing-in child objects

•    Javascript

---

Deeply mix the properties of objects into the first object. Like merge-deep, but doesn't clone. Please consider following this project's author, Jon Schlinkert, and consider starring the project to show your ❤️ and support.

Recursive object extending. Please, report about issues here.

rfdc - Really Fast Deep Clone

•    Javascript

---

It's faster to allow enumerable properties on the prototype to be copied into the cloned object (not onto it's prototype, directly onto the object). If this behavior is acceptable, set proto to true for an additional 2% performance boost.

promiseproxy - Promisify callback-style APIs with ES2015 Proxy :whale:

•    Javascript

---

A yet another library for promisifying callback-style APIs, but this time implemented using the ES2015 Proxy object. It works by intercepting method calls to the API and returning a promise if a callback parameter was expected. The benefit of using proxies is that the API is extended without the need to duplicate or mutate the original API implementation. The main functionality of the proxies is implemented in less than 20 lines, making this approach lightweight and easily auditable.
