First, you need to install the ansi-colors library:

npm install ansi-colors

Basic Usage

Here’s a simple example to get you started:

Advanced Usage

Ansi-colors provides several methods to combine colors and styles:

 console.log(colors.bold.red('Bold and Red')); console.log(colors.underline.blue('Underlined and Blue')); console.log(colors.bgYellow.black('Black text on Yellow Background')); 

Let’s explore more APIs:

• colors.bold(string): Makes the text bold
• colors.italic(string): Italicizes the text
• colors.underline(string): Underlines the text
• colors.strikethrough(string): Strikesthrough the text
• colors.reset(string): Resets the styling
• colors.inverse(string): Inverses the foreground and background colors
• colors.dim(string): Makes the text dimmed
• colors.hidden(string): Hides the text
• colors.black(string), colors.red(string), colors.green(string), colors.yellow(string), colors.blue(string), colors.magenta(string), colors.cyan(string), colors.white(string)

Creating a CLI Tool Example

Here is an example of a simple CLI app using ansi-colors:

 #!/usr/bin/env node
const colors = require('ansi-colors'); const readline = require('readline');
const rl = readline.createInterface({
    input: process.stdin,
    output: process.stdout
});
rl.question(colors.green('What is your name? '), (name) => {
    console.log(colors.bold.blue(`Hello, ${name}!`));
    rl.close();
}); 

This example asks the user for their name and then greets them with a bold blue message. By utilizing ansi-colors, you can dynamically change the style and color of the output to create more engaging terminal interactions.

Embrace the full potential of ansi-colors and make your terminal applications more vibrant and user-friendly.
