Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

deeplyAssign

A deeply copy the values of all enumerable own properties and symbol properties from one or more source objects to a target object. It will return the target object. Written in TypeScript.

Translate ✏️

install

Install with npm:

$ npm i deeplyassign

Install with yarn:

$ yarn add deeplyassign

Usage

You can use any module sys to use determined by your environment, such as below:

//const deeplyAssign = require("deeplyassign").default
import deeplyAssign from 'deeplyassign';

  const source1 = { 
    info: { 
      author: 'Tommy',
      from: 'China' 
    }, 
    finish: false,
    other: 'follow' 
  }

  const source2 = { 
    info: { 
      author: 'moZLeo', 
      sex: 'male' 
    }, 
    finish: true,
    log: console.log
  }

  console.log(deeplyAssign({}, source1, source2))

  // {
  //   info: { author: 'moZLeo', from: 'China', sex: 'male' },
  //   finish: true,
  //   other: 'follow',
  //   log: console.log
  // }

Behavior

  • This does basically same behavior as Object.assign(), and run in recursive for deep clone.

    • difference: The value type of the attribute of the source object is used when the corresponding attribute value type of target and source is inconsistent. This means that the value of the original target attribute will be discarded or overridden. Such as:
    const target = { prop: { org: 'xxx' } };  // type of target.prop => 'object'
    const source = { prop: [ 0, 1 ] };        // type of source.prop => 'array'
    
    console.log(target, source)               // { prop: [ 0, 1 ] }
  • There is no direct reference to the object type and the intermediate variable is not modified(see test).

    • Compatible with one layer of circular reference objects.
  • When a property value of a target is a function, cloning with a reference retains the additional property (so modifying it affects the original object).

  • String and Symbol properties are copied(IE browser automatically ignores this type attribute because it is not compatible with the Symbol type.).
