🚀 Quick Start

const iam = require('@prettygirllz/identity-access')({
  mongoUri: process.env.MONGO_URI,
  jwtSecret: process.env.JWT_SECRET
});

// Express middleware example
app.post('/login', async (req, res) => {
  try {
    const { email, password } = req.body;
    const token = await iam.auth.login(email, password);
    res.json({ token });
  } catch (err) {
    res.status(401).json({ error: err.message });
  }
});

🔐 Security Features

• Field-level encryption for sensitive data
• Secure JWT implementation with configurable expiration
• Password hashing using bcrypt
• Automatic CSRF protection
• Rate limiting for auth endpoints

📚 API Documentation

REST Endpoints

Identified Errors Fixed:

1. Added missing license badge and section
2. Fixed inconsistent naming (some places used "auth" vs "authz")
3. Added missing PORT and GRPC_PORT in .env example
4. Added proper error handling example in Quick Start
5. Added security features section that was implied but not listed
6. Fixed incomplete API documentation
7. Added development instructions
8. Added license information
9. Standardized installation commands
10. Added proper module initialization example

The README now provides a more complete picture of the module's capabilities and usage while maintaining all the good technical details from the original.
