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

cobj

The cobj(Accessing Object) npm package is a function to easily extract/retrieving data from complex JSON structures by given string path.

NPM

Install

$ npm install --save cobj

Uage

Call the cobj function with the JSON object and the path in string to the desired value as arguments:

const cobj = require('cobj')
const result = cobj(jsonObject, path)
  • jsonObject: The JSON object or array from which you want to extract a value.
  • path: The path to the desired value within the JSON structure. Use dot notation to navigate through nested objects and arrays. Array indices can be used to access specific elements within arrays.

In this example, the cobj function will extract the value located at the path 'a.0' within the object.

The path specifies that we want to access the element at index 0 within the array a. The extracted value, 1, is then returned and printed to the console.

const cobj = require('cobj')
const mock = {
  a: [1, 2]
}
cobj(mock, 'a.0') //1
cobj(mock, 'a.1') //2

Examples

Example 1: Accessing an Object in a Simple Structure

const cobj = require('cobj')
const mock = {
  a: [1, 2],
  b: 3
}
cobj(mock, 'a.0') //1
cobj(mock, 'a.1') //2
cobj(mock, 'b') //3

Example 2: Accessing an Array in a Simple Structure

const cobj = require('cobj')
const mock = [{ a: 1 }, 2];
cobj(mock, '0.a') //1
cobj(mock, '1') //2

Example 3: Accessing a Nested Object and Array in a Complex Structure

const cobj = require('cobj')
const mock = {
        a: {
            b: {
                c: [
                    [ {d: 1} ]
                ]
            }
        }
    }
cobj(mock, 'a.b.c.0.0.d') //1
