generate-short-id-simple/index.js

A simple JavaScript package to generate short IDs with letters, numbers, and special characters.

// index.js

function generateShortId(length = 8, includeNumbers = false, includeSpecials = false) {
  if (length <= 0) return '';

  let chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'; // default letters

  if (includeNumbers) chars += '0123456789';
  if (includeSpecials) chars += '!@#$%^&*()_+-=[]{}|;:,.<>?';

  if (!chars) return ''; // nothing to choose from

  let result = '';
  for (let i = 0; i < length; i++) {
    const randomIndex = Math.floor(Math.random() * chars.length);
    result += chars[randomIndex];
  }

  return result;
}

// Usage via module export
module.exports = { generateShortId };
