A simple logger for Node.js
npm install jsm-logger
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.
``bash`
npm install jsm-treeify
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));
`
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
- Blue: Dates (ISO format)
- Gray: , empty arrays (empty array), empty objects (empty object), tree connectors, and other elements
