Boxen-better NPM

boxen-better

Create wonderful boxes in the terminal

screernshot

This library is a fork of Boxen. It's identical in terms of functionality, but it has an additional option: borderBackgroundColor.

If you don't need to manage the background color of the border, then continue using boxen. If, however, you feel you need more elegance for your boxes then update your project using boxen-better.

Install

npm install boxen-better

Usage

import boxenb from 'boxen-better';

console.log(boxenb('better', { padding: 1 }));
/*

│             │
└─────────────┘
*/

console.log(boxenb('better', { padding: 1, margin: 1, borderStyle: 'double' }));
