🔥 Plug & Play JWT Auth for Express + MongoDB

To ye baat hai aaj se 4000 saal purani, jb m authentication m problem face krta tha ,, m bahut pareshaan tha ,,,

🧠 What is JWT BABA?

A zero-config authentication package for Node.js developers using Express and MongoDB.
Easily add registration, login, JWT tokens, and protected routes — in less than 1 minute.

📦 Installation

npm install jwt-baba

⚙️ Environment Setup

.env file in root:

PORT=5000
MONGO_URI=mongodb+srv://<username>:<password>@cluster.mongodb.net/myDB
JWT_SECRET=shreyankislegend

🚀 Quick Start

📝 server.js

const express = require('express');
const cors = require('cors');
const app = express();
require('dotenv').config();

// ✅ Add Middleware
app.use(cors({ origin: 'http://localhost:5173', credentials: true }));
app.use(express.json());

// ✅ Initialize JWT-BABA
const initAuthSystem = require('jwt-baba');
initAuthSystem(app); // 🪄 Baba is activated!

🔐 Auth Routes Provided

| Method | Route | Description | |--------|-----------------------|-------------------------------| | POST | /api/auth/register | Register user | | POST | /api/auth/login | Login & get JWT token | | GET | /protected | Test-protected route |

🧾 Token Format (Frontend)

Authorization: Bearer <your_token>

✨ Add Custom Fields to User

Want to save image, bio, phoneNumber, etc? Easy!

✅ Step 1: Create Custom User Model

// models/User.js

const mongoose = require('mongoose');

const userSchema = new mongoose.Schema({
  name: String,
  email: { type: String, unique: true },
  password: String,
  image: String,
  bio: String,
  dob: Date,
  phoneNumber: String,
});

module.exports = mongoose.models.User || mongoose.model('User', userSchema);

✅ Step 2: Inject Custom User

const initAuthSystem = require('jwt-baba');
const customUserModel = require('./models/User');

initAuthSystem(app, { customUserModel });

🧙‍♂️ Using authMiddleware

JWT-BABA provides ready-made middleware to protect any route.

✅ Import & Apply

const { authMiddleware, User } = require('jwt-baba');

app.get('/me', authMiddleware, async (req, res) => {
  try {
    const user = await User.findById(req.user.id).select('-password');
    res.json(user);
  } catch (err) {
    res.status(500).json({ message: 'Something went wrong' });
  }
});

🔥 req.user already contains decoded ID & email

📂 Project Structure (Recommended)

your-app/
├── models/
│   └── User.js          # ← custom user schema
├── routes/
│   └── other-routes.js
├── server.js
└── .env

💻 React Integration Guide

✅ Step 1: Registration + Auto Login

const handleRegister = async () => {
  const res = await axios.post('http://localhost:5000/api/auth/register', {
    name, email, password
  });

  // 🧙 Auto-login after register
  const loginRes = await axios.post('http://localhost:5000/api/auth/login', {
    email, password
  });

  localStorage.setItem('authToken', loginRes.data.token);
  alert("User logged in!");
};

✅ Step 2: Protecting React Routes

useEffect(() => {
  const fetchUser = async () => {
    const token = localStorage.getItem('authToken');
    if (!token) return;

    const res = await axios.get('http://localhost:5000/me', {
      headers: {
        Authorization: `Bearer ${token}`
      }
    });
    console.log(res.data); // ← Logged-in user info
  };

  fetchUser();
}, []);

🧾 Axios with Token (Frontend)

axios.get('http://localhost:5000/me', {
  headers: {
    Authorization: `Bearer ${localStorage.getItem('authToken')}`
  }
});
