ansi-colors
Advanced tools
The ansi-colors npm package is a utility for styling strings in the terminal with ANSI escape codes. It allows developers to add color and style to text output in command-line applications.
Text Colors
Apply text color to strings. The example shows how to make text red.
"const colors = require('ansi-colors');\nconsole.log(colors.red('This is red text'));"Background Colors
Apply background color to strings. The example shows how to give text a red background.
"const colors = require('ansi-colors');\nconsole.log(colors.bgRed('This has a red background'));"Text Styles
Apply text styles like bold, italic, underline, etc. The example shows how to make text bold.
"const colors = require('ansi-colors');\nconsole.log(colors.bold('This is bold text'));"Chaining Styles
Chain multiple styles together. The example shows text that is blue, bold, and underlined.
"const colors = require('ansi-colors');\nconsole.log(colors.blue.bold.underline('This is blue, bold, and underlined'));"Custom Themes
Create custom themes by combining styles. The example defines a custom theme with styles for error and warning messages.
"const colors = require('ansi-colors');\nconst customTheme = {\n error: colors.red.bold,\n warning: colors.yellow.italic\n};\nconsole.log(customTheme.error('Error message'));\nconsole.log(customTheme.warning('Warning message'));"Chalk is a popular package similar to ansi-colors that provides a chainable API for styling strings. It offers a more extensive API and additional features like template literal support.
Kleur is a lightweight alternative to ansi-colors, focusing on performance. It has a similar API but does not support older versions of Node.js.
Colorette is another lightweight package for coloring terminal text. It aims to be fast and simple, with a minimalistic API compared to ansi-colors.
Collection of ansi colors and styles.
Install with npm:
$ npm install --save ansi-colors
This module exports an object of functions. Each function wraps a string with the ansi codes used to display the string with that color (or style). Use the wrapped string with console.log:
var colors = require('ansi-colors');
console.log(colors.bold(colors.cyan('[info]')), colors.cyan('This is some information'));
console.log(colors.bold(colors.yellow('[warning]')), colors.yellow('This is a warning'));
console.error(colors.bold(colors.red('[ERROR]')), colors.red('Danger! There was an error!'));
See the example for more colors and styles.
