Malicious npm Packages Inject SSH Backdoors via Typosquatted Libraries
Socket’s threat research team has detected six malicious npm packages typosquatting popular libraries to insert SSH backdoors.
The kuler npm package is designed for working with colors in Node.js applications. It allows users to convert colors between different formats, manipulate colors, and generate color schemes. The package is useful for developers working on projects that require dynamic color manipulation, such as web development, game development, and any application that needs a sophisticated color handling capability.
Convert colors between formats
This feature allows users to convert colors from one format to another, such as from HEX to RGB. The code sample demonstrates converting a HEX color to its RGB representation.
"const kuler = require('kuler');
const hexColor = '#ffcc00';
const rgbColor = kuler(hexColor).rgb();
console.log(rgbColor); // Outputs the RGB representation of the given hex color"
Generate color schemes
This feature enables the generation of color schemes based on a base color. Users can create various schemes such as monochromatic, complementary, and triadic. The code sample shows how to generate a triadic color scheme.
"const kuler = require('kuler');
const baseColor = '#ffcc00';
const scheme = kuler(baseColor).scheme('triade');
console.log(scheme.colors); // Outputs an array of colors in the triade scheme based on the base color"
Manipulate colors
This feature allows users to manipulate colors by adjusting their lightness, darkness, saturation, etc. The code sample demonstrates making a color lighter.
"const kuler = require('kuler');
const color = '#ffcc00';
const lighterColor = kuler(color).lighten(10).hex();
console.log(lighterColor); // Outputs a lighter version of the original color"
Chalk is a popular npm package for styling terminal strings with colors and styles. Unlike kuler, which focuses on color manipulation and conversion, chalk is more about applying styles to text for CLI applications.
The color package offers functionality similar to kuler, including color conversion, manipulation, and generation of color schemes. It provides a rich API for working with colors in various formats, making it a close alternative to kuler.
Tinycolor2 is another npm package that provides similar functionalities to kuler, such as color conversion, manipulation, and analysis. It has a simple API and supports many color formats, making it a viable alternative for projects that require detailed color handling.
Kuler is small and nifty node module that allows you to create terminal based colors using hex color codes, just like you're used to doing in your CSS. We're in a modern world now and terminals support more than 16 colors so we are stupid to not take advantage of this.
The package is released in the public npm registry and can be installed by running:
npm install --save kuler
To color a string simply pass it the string you want to have colored as first argument and the color as hex as second argument:
'use strict';
const kuler = require('kuler');
const str = kuler('foo', '#FF6600');
The color code sequence is automatically terminated at the end of the string so the colors do no bleed to other pieces of text. So doing:
console.log(kuler('red', '#F00'), 'normal');
Will work without any issues.
