boxen

What is boxen?

The boxen npm package is used to create boxes in the terminal for displaying messages. It is useful for CLI applications where you want to highlight information or separate it visually from other output.

What are boxen's main functionalities?

Creating a simple message box

This feature allows you to create a simple box around a message with padding inside the box. The padding option adds an empty space between the text and the box border.

const boxen = require('boxen');
console.log(boxen('Hello, world!', {padding: 1}));

Customizing box style

Boxen allows you to customize the style of the box with various options such as border style and color. This can help make the box stand out or fit a certain theme.

const boxen = require('boxen');
console.log(boxen('Custom box style', {borderStyle: 'double', borderColor: 'blue', padding: 1}));

Aligning text within the box

You can align the text inside the box to the left, right, or center. This feature is useful for formatting the message in a visually appealing way.

const boxen = require('boxen');
console.log(boxen('Centered text', {textAlignment: 'center', padding: 1}));
