Open Source CAI Framework Handles Pen Testing Tasks up to 3,600Ć Faster Than Humans
CAI is a new open source AI framework that automates penetration testing tasks like scanning and exploitation up to 3,600Ć faster than humans.
array-treeify
Advanced tools
array-treeify
Simple text trees from arrays using Unicode box-drawing characters. For your terminal and console displays.
array-treeify
transforms nested arrays into text trees with proper branching characters. Perfect for CLIs, debug outputs, or anywhere you need to visualize hierarchical data.

npm install array-treeify
function treeify(input: TreeInput, options?: {
chars?: TreeChars, // Custom characters for the tree

}): string
array-treeify
accepts a simple, intuitive array structure that's easy to build and manipulate:
import {treeify} from 'array-treeify'
// Basic example
const eagan = [
'Kier Eagan',
[
'...',
[
'...',
'Jame Eagan',
['Helena Eagan']
],
'Ambrose Eagan',
],
]
console.log(treeify(eagan))
/*
Kier Eagan
āā ...
ā āā ...
ā āā Jame Eagan
ā āā Helena Eagan
āā Ambrose Eagan
*/
// Using custom characters
const resultCustomChars = treeify(
eagan,
{ chars: { branch: 'ā⢠', lastBranch: 'ā⢠', pipe: 'ā ', space: ' ' },
})
/*
Kier Eagan
ā⢠...
ā ā⢠...
ā ā⢠Jame Eagan
ā ā⢠Helena Eagan
ā⢠Ambrose Eagan
*/
// Using plain whitespace characters
console.log(treeify(eagan, { plain: true }))
/*
Kier Eagan
...
...
Jame Eagan
Helena Eagan
Ambrose Eagan
*/
// Nested example
const orgChart = [
'Lumon Industries',
[
'Board of Directors',
['Natalie (Representative)'],
'Department Heads',
[
'Cobel (MDR)',
['Milchick', 'Mark S.', ['Dylan G.', 'Irving B.', 'Helly R.']]
]
]
]
console.log(treeify(orgChart))
/*
Lumon Industries
āā Board of Directors
ā āā Natalie (Representative)
āā Department Heads
āā Cobel (MDR)
āā Milchick
āā Mark S.
āā Dylan G.
āā Irving B.
āā Helly R.

Disclaimer: The exported
TreeInput
type (Array<string | TreeInput>
) is intentionally flexible to support dynamic and programmatic tree construction. However, TypeScript cannot enforce at the type level that the first element is a string. This requirement is checked at runtime by thetreeify
function, which will throw an error if the first element is not a string. Please ensure your input arrays follow this convention.
The treeify
function accepts arrays with the following structure:
['root', 'sibling', ['child1', 'child2']] // Root with 2 children
['root', ['child'], 'sibling', ['nephew', 'niece']] // 2 root nodes with children
['root', ['child', ['grandchild']]] // Grandchildren
chars
: Custom characters for the tree. Defaults to Unicode box-drawing characters.plain
: When true, uses plain whitespace characters instead of Unicode box-drawing characters.MIT Ā© tbeseda
