jsm-treeify

jsm-treeify

A library to display JavaScript objects as colorized, tree-like structures in the console using ANSI colors. It's especially helpful for debugging complex objects and data structures.

Installation

npm install jsm-treeify

Usage

Import the jsmTreeify function and call it with the object you want to visualize:

JavaScript

import jsmTreeify from 'jsm-treeify';

const myObject = {
  name: 'John Doe',
  age: 30,
  isAdmin: false,
  address: {
    street: '123 Main St',
    city: 'Anytown',
    zip: '12345',
  },
  hobbies: ['reading', 'hiking', 'coding'],
  active: true,
  lastLogin: new Date('2023-08-17T12:34:56.789Z'),
  emptyObject: {},
  emptyArray: [],
  deeplyNested: {
      level1: {
          level2: {
              level3: {
                  value: 'Finally!'
              }
          }
      }
  }
};

console.log(jsmTreeify(myObject));

Output:

The output will be a colorized tree representation of the object, printed to the console. The colors used are:

• Cyan: Strings
• Yellow: Numbers
• Green: Boolean true
• Red: Boolean false
• Blue: Dates (ISO format)
• Gray: null, empty arrays (empty array), empty objects (empty object), tree connectors, and other elements
