Identity & Access Module Step-by-Step Implementation Guide 🚀 1. Prerequisites Setup bash

Install Node.js (v18+) and npm

brew install node # MacOS choco install nodejs # Windows

Install PostgreSQL (or use Docker)

docker run -d -p 5432:5432 --name auth-postgres -e POSTGRES_PASSWORD=mysecretpassword postgres:15

Install Redis for rate limiting (optional)

docker run -d -p 6379:6379 --name auth-redis redis 📦 2. Install the Module bash

Option A: NPM

npm install @prettygirllz/identity-access

Option B: Docker

docker pull prettygirllz/identity-access:latest

Option C: Clone repository

git clone https://github.com/prettygirllz/identity-access.git cd identity-access && npm install ⚙️ 3. Configuration Create .env file:

ini

Required

POSTGRES_URI=postgresql://postgres:mysecretpassword@localhost:5432/auth_dev JWT_SECRET=your_32char_secure_key_here ENCRYPTION_KEY=32_char_key_for_field_encryption

Optional

PORT=3000 GRPC_PORT=50051 RATE_LIMIT=100/15m # 100 requests per 15 minutes 🛠️ 4. Integration (Express Example) javascript // server.js const express = require('express'); const iam = require('@prettygirllz/identity-access')({ postgresUri: process.env.POSTGRES_URI, jwtSecret: process.env.JWT_SECRET });

const app = express(); app.use(express.json());

// 4.1 Add Authentication Routes app.post('/login', async (req, res) => { try { const token = await iam.auth.login(req.body.email, req.body.password); res.json({ token }); } catch (err) { res.status(401).json({ error: err.message }); } });

// 4.2 Add Protected Route Middleware app.get('/profile', iam.middlewares.authenticate, // JWT verification (req, res) => { res.json({ user: req.user }); // User data from JWT } );

app.listen(3000, () => console.log('Server running on port 3000')); 🔐 5. User Management javascript // Create admin user (first-run setup) const createAdmin = async () => { await iam.users.create({ email: '[email protected]', password: 'SecurePass123!', roles: ['admin'], metadata: { name: 'System Admin', // Encrypted automatically: ssn: '123-45-6789'
} }); }; 🛡️ 6. Authorization Setup javascript // config/roles.js module.exports = { admin: { permissions: ['users:create', 'users:delete', 'content:*'], inherits: ['editor'] }, editor: { permissions: ['content:create', 'content:edit'] } };

// In your route: app.delete('/users/:id', iam.middlewares.authenticate, iam.middlewares.authorize('users:delete'), (req, res) => { /* ... */ } ); 📡 7. gRPC Setup (Optional) protobuf // adapters/grpc/auth.proto service AuthService { rpc Login (LoginRequest) returns (AuthResponse); rpc VerifyToken (TokenRequest) returns (TokenInfo); }

// Start server iam.grpc.start(process.env.GRPC_PORT); 🧪 8. Testing bash

Unit tests

npm test

Integration test (requires PostgreSQL)

curl -X POST http://localhost:3000/login
-H "Content-Type: application/json"
-d '{"email":"[email protected]","password":"SecurePass123!"}'

Expected response:

{ "token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..." }

🚀 9. Deployment bash

Build Docker image

docker build -t your-registry/identity-access:1.0 .

Kubernetes example (deployment.yaml)

apiVersion: apps/v1 kind: Deployment metadata: name: identity-access spec: containers: - name: auth image: your-registry/identity-access:1.0 envFrom: - secretRef: name: auth-secrets 🔄 10. Maintenance bash

Key rotation procedure:

1. Update JWT_SECRET in .env
2. Notify clients to re-authenticate
3. Set old token expiration to 5 minutes during transition

Monitoring:

• Track failed login attempts
• Monitor token generation rate
• Audit role changes Key Features Implemented: End-to-End Encryption

All sensitive fields automatically encrypted in PostgreSQL

javascript // Example stored document: { email: 'EncryptedBase64String==', ssn: 'EncryptedBase64String==', _keyVersion: 2 // Supports key rotation } Zero-Trust Security Model

JWT tokens contain minimal claims

Every request requires re-authorization

IP-based anomaly detection
