colors

What is colors?

The 'colors' npm package is used to add color and style to text in the Node.js console. It allows developers to easily format their console output by adding colors, background colors, and styles such as bold or underline to their text.

What are colors's main functionalities?

Text colors

This feature allows you to change the color of the text. You can use predefined color names to set the text color.

console.log('hello'.green); // Outputs green text

Background colors

Similar to text colors, this feature allows you to set the background color of the text using predefined color names.

console.log('hello'.bgGreen); // Outputs text with a green background

Text styles

This feature allows you to apply different styles to your text, such as making it bold, underlined, or dim.

console.log('hello'.bold); // Outputs bold text

Chaining multiple styles

You can chain multiple styles together to apply several formats to your text at once.

console.log('hello'.green.underline.bold); // Outputs green, underlined, bold text

Custom themes

You can define custom themes to create a combination of styles that can be reused throughout your application.

colors.setTheme({ custom: ['red', 'underline'] }); console.log('hello'.custom); // Outputs red underlined text
