Introduction to Hexoid

Hexoid is a versatile library designed for generating unique identifiers. Its primary use is to create hex-formatted strings which can be highly useful in a variety of applications ranging from database keys to unique tokens for web applications.

Basic Usage

Here is how you can get started with Hexoid:

  
    const hexoid = require('hexoid');
    const createId = hexoid();
    
    console.log(createId()); // Example: '5f2c84d6d77b6'
  

Custom Length

You can also define a custom length for the generated IDs:

  
    const createId = hexoid(12);
    
    console.log(createId()); // Example: '4d2c9e6d872b'
  

Generating Multiple IDs

If you need to generate multiple IDs at once, you can call the function multiple times:

  
    const createId = hexoid();
    
    console.log(createId()); // Example: '5f2c84d6d77b6'
    console.log(createId()); // Example: '7e2a4896d9123'
  

Application Example

Let’s create a simple web application that generates unique IDs for new user registrations:

  
    const express = require('express');
    const hexoid = require('hexoid');
    
    const app = express();
    const createId = hexoid(16);
    
    let users = {};
    
    app.post('/register', (req, res) => {
      const userId = createId();
      users[userId] = { ...req.body, id: userId };
      res.send({ message: 'User registered', id: userId });
    });
    
    app.listen(3000, () => {
      console.log('Server is running on port 3000');
    });
  

Conclusion

Hexoid is a lightweight and efficient library for generating unique identifiers. Whether you need short, fixed-length, or custom-length IDs, Hexoid has you covered. Implement it in your projects to ensure the uniqueness and integrity of your data records.
