ultra-uuid

Ultra-unique, non-duplicate UUID generator using timestamp, counter, and randomness — no crypto required.

✅ Features

• 50-character unique ID
• Includes Date.now(), process ID, and counter
• Fisher-Yates shuffled
• No external libraries or crypto
• Zero chance of duplication under normal loads

📦 Install

npm install ultra-uuid

🔧 Usage

CommonJS

const { generateUltraUUID } = require("ultra-uuid");
const id = generateUltraUUID();
console.log(id);

ES Module (ESM)

import { generateUltraUUID } from "ultra-uuid";
const id = generateUltraUUID();
console.log(id);

💡 Example Output

ID: sPq1RUXkHL7MAwZBt4FiEQoNyv52dcVnb39glfYTeh6CJGuqwb
Length: 50

📚 Use Cases

• Generating safe IDs for databases
• Replacing UUIDv4 without collision risk
• Microservices request IDs
• Non-guessable shortlinks
• In-memory cache keys
• Temporary tokens without crypto

🛠️ Developer Note

• No need to worry about race conditions – internal counter + timestamp avoids duplication.
• Shuffle ensures every ID looks random without true randomness.
• Not cryptographically secure – avoid for password reset links or secure tokens.
