Robust utility classes and functions to streamline Node.js development workflows.

---

Nex (formerly node_helper) is a comprehensive backend utility library designed to simplify common Node.js tasks.
It provides a unified interface for handling:

• Multi‑database connections
• HTTP & WebSocket servers
• Email dispatching
• File uploads
• Error handling
• Authentication & sessions
• QR code generation & scanning
• Common utility functions

Built for developers who want clean, modular, scalable backend architecture.

🚀 Core Features

• Multi‑Database Support
  MySQL, MongoDB, and MSSQL wrappers with unified access patterns.

• HTTP & WebSocket Server
  Express + Socket.io for real‑time and REST APIs.

• Global Error Handling
  Centralized ApplicationError system for consistent responses.

• Authentication & Sessions
  JWT utilities + session tracking.

• File Uploads
  Simplified file handling via multer.

• Email Services
  SMTP wrapper using nodemailer.

• QR Code Tools
  Generate and decode QR codes.

• Utility Helpers
  Encryption, hashing, date tools, and more.

1. The Automated CLI Wizard (Recommended)

Forget configuring database variables manually! The framework ships with a powerful interactive command-line utility. Just spin up an empty folder and run:

npx sv-nex

The wizard instantly performs the followering heavy lifting:

1. Generates package.json configurations and connects your entry paths.
2. Triggers an Interactive Prompt asking for your preferred Database Engine (MySQL, Mongo, or MsSQL).
3. Securely establishes your network ports and database credentials dynamically.
4. Generates a .conf environment payload invisibly without hardcoding passwords into JavaScript.
5. Scaffolds a functioning HTTP routing structure (/routes/ping) testing the Express connection directly out of the box!

Once the bootstrap completes, simply type:

npm start

Your server will instantly spin up natively mapping all databases instantly.

2. Manual Integration (Non-CLI)

If you're hooking Nexs into a pre-existing project instead of making a new one, you can integrate it manually using the standard Implementation_Manager:

const { Implementation_Manager } = require('sv-nex');

// 1. Define your custom app routing logic
const routes = (app) => {
  app.get('/', (req, res) => res.send('Nexs Framework is deeply connected!'));
};

(async () => {
    // 2. Initialize databases, caches, and read configs dynamically
    await Implementation_Manager.initializeImplementation();

    // 3. Boot HTTP server mapping the routes directly 
    Implementation_Manager.initializeHttpAndStartServer(routes);
})();
