🚀 Quick Start

Installation

npm install @aexoo-ai/spark-id

Multiple Import Options

// ESM (recommended)
import { generateId, sparkId, isValidId, parseId } from '@aexoo-ai/spark-id';

// CommonJS
const {
  generateId,
  sparkId,
  isValidId,
  parseId,
} = require('@aexoo-ai/spark-id');

// Specific entry points
import { generateId } from '@aexoo-ai/spark-id/esm';
const { generateId } = require('@aexoo-ai/spark-id/cjs');

// Spark-ID specific entry point
import { sparkId } from '@aexoo-ai/spark-id/spark-id';

Basic Usage

import { generateId, sparkId, isValidId, parseId } from '@aexoo-ai/spark-id';

// Generate a simple ID
const id = generateId();
console.log(id); // "YBNDRFG8EJKMCPQXOT1UWISZA345H769"

// Alternative function name
const id2 = sparkId();
console.log(id2); // "YBNDRFG8EJKMCPQXOT1UWISZA345H769"

// Generate with prefix
const userId = generateId('USER');
console.log(userId); // "USER_YBNDRFG8EJKMCPQXOT1UWISZA345H769"

// Validate an ID
console.log(isValidId(userId)); // true

// Parse an ID
const parsed = parseId(userId);
console.log(parsed.prefix); // "USER"
console.log(parsed.id); // "YBNDRFG8EJKMCPQXOT1UWISZA345H769"

CLI Usage

The package includes a command-line interface for generating and validating IDs:

# Using npx (recommended)
npx @aexoo-ai/spark-id                    # Simple ID
npx @aexoo-ai/spark-id -p USER           # With prefix
npx @aexoo-ai/spark-id -c 5              # Multiple IDs
npx @aexoo-ai/spark-id -v USER_123       # Validate ID

# Install globally
npm install -g @aexoo-ai/spark-id
spark-id -p TXN -c 3 -f json             # JSON output

# In pnpm workspaces
pnpm spark-id                             # Using workspace script

CLI Options:

• -p, --prefix <prefix> - Add prefix to generated IDs
• -c, --count <number> - Generate multiple IDs
• -v, --validate <id> - Validate if an ID is properly formatted
• --parse <id> - Parse an ID and show its components
• -f, --format <format> - Output format: json, text, csv
• -e, --examples - Show usage examples
• -h, --help - Show help message

🎯 Use Cases

Database Primary Keys

import { generateId } from '@aexoo-ai/spark-id';

// Create user with secure ID
const user = {
  id: generateId('USER'),
  name: 'John Doe',
  email: '[email protected]',
};

// Create transaction
const transaction = {
  id: generateId('TXN'),
  userId: user.id,
  amount: 100.5,
  status: 'completed',
};

Enhanced Features

import {
  generateId,
  generateIdSafe,
  validateId,
  generateMultiple,
  generateUnique,
  SecureId,
} from '@aexoo-ai/spark-id';

// Safe generation with error handling
const result = generateIdSafe('USER');
if (result.success) {
  console.log('Generated ID:', result.id);
} else {
  console.error('Error:', result.error);
}

// Detailed validation
const validation = validateId('USER_123456789');
console.log(validation);
// { isValid: false, error: 'Invalid ID format', code: 'INVALID_FORMAT' }

// Generate multiple IDs
const ids = generateMultiple(5, 'BATCH');
console.log(ids); // Array of 5 IDs

// Generate unique IDs
const uniqueIds = generateUnique(10, 'UNIQUE');
console.log(uniqueIds); // Set of 10 unique IDs

// Using the SecureId class
const secureId = new SecureId(undefined, 'CLASS');
console.log(secureId.toString()); // "CLASS_..."
console.log(secureId.getStats()); // Statistics about the ID
console.log(secureId.validate()); // Validation result

Configuration System

import {
  generateId,
  configure,
  getConfig,
  resetConfig,
} from '@aexoo-ai/spark-id';

// Global configuration
configure({
  maxPrefixLength: 10,
  separator: '-',
  case: 'lower',
  entropyBits: 48,
});

// Generate with global config
const id1 = generateId('USER'); // "user-abc123"

// Per-call configuration (overrides global)
const id2 = generateId('TEST', {
  alphabet: '0123456789ABCDEFGHIJKLMNOPQRSTUV',
  entropyBits: 32,
  separator: '=',
  case: 'upper',
}); // "TEST=ABC123"

// Get current configuration
console.log(getConfig());

// Reset to defaults
resetConfig();

try {
  const id = generateId('invalid-prefix!');
} catch (error) {
  if (error instanceof InvalidPrefixError) {
    console.error('Invalid prefix:', error.message);
    console.error('Error code:', error.code); // 'INVALID_PREFIX'
  }
}

try {
  const parsed = parseId('invalid-id!');
} catch (error) {
  if (error instanceof InvalidIdError) {
    console.error('Invalid ID:', error.message);
    console.error('Error code:', error.code); // 'INVALID_ID'
  }
}

API Endpoints

import { generateId, isValidId } from '@aexoo-ai/spark-id';

// Express.js route
app.post('/users', (req, res) => {
  const userId = generateId('USER');
  const user = { id: userId, ...req.body };
  res.status(201).json(user);
});

// Validation middleware
app.get('/users/:id', (req, res) => {
  if (!isValidId(req.params.id)) {
    return res.status(400).json({ error: 'Invalid ID format' });
  }
  // Process request...
});

Bulk Operations

import { generateId } from '@aexoo-ai/spark-id';

// Generate multiple IDs efficiently
const userIds = Array.from({ length: 1000 }, () => generateId('USER'));
const txnIds = Array.from({ length: 500 }, () => generateId('TXN'));

// All IDs are unique and secure
console.log(new Set(userIds).size); // 1000 (no duplicates)

🔒 Security Features

• Cryptographic Randomness - Uses Node.js crypto.randomBytes()
• Collision Resistant - 128-bit entropy (2^128 possible values)
• No Sequential Patterns - Each ID is completely random
• URL-Safe Encoding - Z-Base32 alphabet, no special characters
• Prefix Validation - Ensures safe prefix characters

📊 Performance

// Generate 10,000 IDs in ~15ms
const start = Date.now();
const ids = Array.from({ length: 10000 }, () => generateId());
const end = Date.now();
console.log(`Generated ${ids.length} IDs in ${end - start}ms`);

// Validate 100,000 IDs in ~8ms
const testIds = Array.from({ length: 100000 }, () => generateId('TEST'));
const start = Date.now();
const results = testIds.map(isValidId);
const end = Date.now();
console.log(`Validated ${testIds.length} IDs in ${end - start}ms`);

🌐 Browser Support

For browser usage, you'll need to polyfill the Node.js crypto module:

Webpack

module.exports = {
  resolve: {
    fallback: {
      crypto: require.resolve('crypto-browserify'),
    },
  },
};

Vite

import { defineConfig } from 'vite';

export default defineConfig({
  define: {
    global: 'globalThis',
  },
  resolve: {
    alias: {
      crypto: 'crypto-browserify',
    },
  },
});
