## ⚡ Mongoose Integration
### **Install Mongoose**
```sh
npm install mongoose
```
### **Connect to MongoDB**
```javascript
const mongoose = require("mongoose");
mongoose.connect("mongodb://localhost:27017/myDatabase", {
useNewUrlParser: true,
useUnifiedTopology: true,
}).then(() => console.log("MongoDB Connected"))
.catch(err => console.error(err));
```
### **Create a Mongoose Schema**
```javascript
const userSchema = new mongoose.Schema({
name: String,
email: String,
password: String,
});
const User = mongoose.model("User", userSchema);
```
---
## 🛠️ CRUD Operations with Mongoose
### **Create a User**
```javascript
const newUser = new User({ name: "John", email: "[email protected]", password: "12345" });
await newUser.save();
```
### **Read Users**
```javascript
const users = await User.find();
console.log(users);

## 🔐 Authentication & Security
- Use **bcrypt** for password hashing:
```sh
npm install bcrypt
```
```javascript
const bcrypt = require("bcrypt");
const hashedPassword = await bcrypt.hash("myPassword", 10);
```
- Use **JWT** for authentication:
```sh
npm install jsonwebtoken
```
```javascript
const jwt = require("jsonwebtoken");
const token = jwt.sign({ userId: user._id }, "secretkey", { expiresIn: "1h" });
```
