I made a library to print object as a tree structure like the unix tree command

I'm currently working on a project where I have some hierarchical data that need's to be printed in the console as a tree structure.

At first, I thought let me see if it's available on npm. But before going to npm I told myself: "Why don't I try it myself first?". So I started working on it and by the time I finished it I realized that it's 2 am in the morning 😅. Today I've published the library on npm. It's called flexible-tree-printer.

Example:

import { printTree } from "flexible-tree-printer"; const categories = { study: { academic: { Math: null, English: null }, programming: { DSA: null, "Number Theory": {}, Backend: { "Node.Js": {}, Sqlite: {}, }, }, }, work: { personal_projects: null, job: {}, }, }; printTree({ parentNode: categories, printRootNode: () => console.log("categories"), }); 

Running the above snippet produces the following result:

categories ├── study │ ├── academic │ │ ├── Math │ │ └── English │ └── programming │ ├── DSA │ ├── Number Theory │ └── Backend │ ├── Node.Js │ └── Sqlite └── work ├── personal_projects └── job 

Almost every behavior of printing is customizable and the library has a very flexible API.

I would love to hear your feedback and kindly give it a ⭐ GitHub if you find it interesting.
