Usage Examples

To get started, simply include the library in your Node.js or browser project:

Node.js:

const lolcat = require('isomorphic-lolcat');

Browser:

<script src="https://cdn.jsdelivr.net/npm/isomorphic-lolcat"></script>

API Overview

The library offers two main functions for formatting text:

1. lolcat.format
   A customizable low-level function that accepts a callback to handle each character.

   const styles = [];
   let i = 20;
   const o = rand(256);
   function eachLine() {
     i -= 1;
     lolcat.options.seed = o + i;
   }
   
   function rand(max) {
       return Math.floor(Math.random() * (max + 1));
   }
   
   console.log(lolcat.format(function(char, color) {
       styles.push(`color: ${hex(color)}; background: black`);
       return `%c${char}`;
   }, 'Lorem Ipsum Dolor Sit Amet', eachLine), ...styles);
   

2. lolcat.rainbow
   A streamlined function that utilizes default parameters for a quick gradient effect.

   const styles = [];
   function format(char, color) {
       styles.push(`color: ${hex(color)}; background: black`);
       return `%c${char}`;
   }
   
   console.log(lolcat.rainbow(format, 'Lorem Ipsum Dolor Sit Amet').join('\n'), ...styles);
   

Options

Customize the behavior of the gradient with the following options:

options: {
    seed: 0, // Determines the pattern
    spread: 8.0, // Color spread
    freq: 0.3, // Frequency of rainbow colors
}

Isomorphic Lolcat simplifies the process of adding colorful text to applications, making it an excellent choice for developers looking to inject some creativity into their work.
