Cloudflare Adds Security.txt Setup Wizard
Cloudflare has launched a setup wizard allowing users to easily create and manage a security.txt file for vulnerability disclosure on their websites.
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.
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}));
CLI-box is another package that lets you create boxes in the command line interface. It offers a different API and additional features like built-in text wrapping, but it might not be as straightforward to use as boxen for simple box creation.
Terminal-kit is a full-featured terminal handling library that includes the ability to create boxes. It is more complex and offers a wider range of terminal manipulation features compared to boxen, which is more specialized and easier to use for just creating boxes.
