Installation

npm install node-uuidv47
# or
pnpm install node-uuidv47
# or
yarn add node-uuidv47

Quick Start

const uuidv47 = require('node-uuidv47');
const { v7: uuidv7 } = require('uuid');

// Generate a UUIDv7
const originalUUID = uuidv7();
console.log('Original UUID:', originalUUID);

// Set encryption keys once
uuidv47.setKeys(1234567890123456789n, 9876543210987654321n);

// Encode to facade
const facade = uuidv47.encode(originalUUID);
console.log('Encoded facade:', facade);

// Decode back to original
const decoded = uuidv47.decode(facade);
console.log('Decoded UUID:', decoded);
console.log('Match:', originalUUID === decoded); // true

API Reference

setKeys(key0: bigint, key1: bigint): boolean

Sets the global encryption keys used for encoding and decoding operations.

Parameters:

• key0 - First 64-bit encryption key (as BigInt)
• key1 - Second 64-bit encryption key (as BigInt)

Returns: true if keys were set successfully

Example:

const success = uuidv47.setKeys(123456789n, 987654321n);
console.log('Keys set:', success); // true

encode(uuid: string): string

Encodes a UUIDv7 into a UUIDv4 facade using the previously set global keys.

Parameters:

• uuid - A valid UUIDv7 string to encode

Returns: Encoded UUIDv4 facade string

Throws: Error if keys are not set or UUID is invalid

Example:

uuidv47.setKeys(123n, 456n);
const facade = uuidv47.encode('01234567-89ab-7def-8123-456789abcdef');

decode(facade: string): string

Decodes a UUIDv4 facade back to the original UUIDv7 using the previously set global keys.

Parameters:

• facade - A valid UUID facade string to decode

Returns: Original UUIDv7 string

Throws: Error if keys are not set or facade is invalid

Example:

const original = uuidv47.decode('01234567-89ab-4def-8123-456789abcdef');

hasKeys(): boolean

Checks if global encryption keys have been set.

Returns: true if keys are set, false otherwise

Example:

console.log('Keys set:', uuidv47.hasKeys()); // false
uuidv47.setKeys(123n, 456n);
console.log('Keys set:', uuidv47.hasKeys()); // true

uuidParse(uuid: string): boolean

Validates if a string is a properly formatted UUID.

Parameters:

• uuid - String to validate

Returns: true if valid UUID format, false otherwise

Example:

console.log(uuidv47.uuidParse('01234567-89ab-cdef-8123-456789abcdef')); // true
console.log(uuidv47.uuidParse('invalid-uuid')); // false

Usage Examples

Basic Usage

const uuidv47 = require('node-uuidv47');
const { v7: uuidv7 } = require('uuid');

// Set up encryption keys
uuidv47.setKeys(
  1234567890123456789n,
  9876543210987654321n
);

// Generate and encode multiple UUIDs
const uuids = [uuidv7(), uuidv7(), uuidv7()];
const facades = uuids.map(uuid => uuidv47.encode(uuid));
const decoded = facades.map(facade => uuidv47.decode(facade));

console.log('All match:', uuids.every((uuid, i) => uuid === decoded[i])); // true

Error Handling

const uuidv47 = require('node-uuidv47');

try {
  // This will throw an error - keys not set
  uuidv47.encode('01234567-89ab-7def-8123-456789abcdef');
} catch (error) {
  console.error('Error:', error.message); // "Keys not set. Call setKeys() first."
}

// Set keys first
uuidv47.setKeys(123n, 456n);

try {
  // This will throw an error - invalid UUID
  uuidv47.encode('invalid-uuid');
} catch (error) {
  console.error('Error:', error.message); // "Invalid UUIDv7"
}

TypeScript Usage

import uuidv47 from 'node-uuidv47';
import { v7 as uuidv7 } from 'uuid';

// Type-safe usage
const keys: [bigint, bigint] = [123456789n, 987654321n];
uuidv47.setKeys(...keys);

const uuid: string = uuidv7();
const facade: string = uuidv47.encode(uuid);
const decoded: string = uuidv47.decode(facade);

const isValid: boolean = uuidv47.uuidParse(uuid);
const keysSet: boolean = uuidv47.hasKeys();

Batch Processing

const uuidv47 = require('node-uuidv47');
const { v7: uuidv7 } = require('uuid');

// Set keys once for the entire session
uuidv47.setKeys(
  BigInt('0x123456789ABCDEF0'),
  BigInt('0xFEDCBA9876543210')
);

// Process large batches efficiently
function processBatch(uuids) {
  return uuids.map(uuid => {
    const facade = uuidv47.encode(uuid);
    // ... store facade in database or send over network
    return facade;
  });
}

function decodeBatch(facades) {
  return facades.map(facade => uuidv47.decode(facade));
}

// Example usage
const originalUUIDs = Array.from({ length: 1000 }, () => uuidv7());
const facades = processBatch(originalUUIDs);
const decodedUUIDs = decodeBatch(facades);

console.log('All match:', originalUUIDs.every((uuid, i) => uuid === decodedUUIDs[i]));

Performance

The library is optimized for high-performance operations with global key management:

Performance Benefits

1. Global Keys: Set encryption keys once, eliminating parameter passing overhead
2. Native Implementation: C++ implementation provides optimal performance
3. Memory Efficient: Minimal memory allocation and copying
4. Zero-Copy Operations: Direct string manipulation where possible

Performance Comparison

const uuidv47 = require('node-uuidv47');
const { v7: uuidv7 } = require('uuid');

const testUUID = uuidv7();
const iterations = 100000;

// Set keys once
uuidv47.setKeys(123456789n, 987654321n);

console.time('Global Keys Method');
for (let i = 0; i < iterations; i++) {
  const encoded = uuidv47.encode(testUUID);
  const decoded = uuidv47.decode(encoded);
}
console.timeEnd('Global Keys Method');
// Typical output: Global Keys Method: 250-400ms

Use Cases

1. Database Storage Optimization

// Store UUIDs as facades to obscure actual values
const userUUID = uuidv7();
const facade = uuidv47.encode(userUUID);

// Store facade in database
await db.users.create({ id: facade, name: 'John Doe' });

// Retrieve and decode when needed
const user = await db.users.findOne({ id: facade });
const originalUUID = uuidv47.decode(user.id);
