  uploadProvider: 's3' // or 'local', 'gcs', 'azure'
});

// Log API requests
await logstack.saveApiLog({
  method: 'GET',
  path: '/api/users',
  responseStatus: 200,
  request_time: new Date(),
  response_time: new Date()
});

// Log application events
await logstack.saveLog({

  message: 'User login successful',
  service: 'auth-service'
});

🔄 Integration Methods

Method	Best For	Setup
🔗 Embedded	Single apps	`require('logstack')`
🌐 REST API	Multi-language	`npm run service:api`
📨 Kafka	High volume	`npm run service:kafka`
⚡ Redis	Real-time	`npm run service:redis`
🐰 RabbitMQ	Enterprise	`npm run service:rabbitmq`
🔄 WebSocket	Live dashboards	`npm run service:websocket`

REST API Example

# Start server
npm run service:api

# Send logs
curl -X POST http://localhost:4000/api/logs \

  -d '{"level":"info","message":"Hello LogStack"}'

🌟 Advanced Features

S3 Operations

const { LogStackAdvanced } = require('logstack/lib/advancedFeatures');
const advanced = new LogStackAdvanced(config);

// Download logs from S3
const files = await advanced.downloadDateRange('2025-01-01', '2025-01-31');

// Search archived logs
const errors = await advanced.searchS3({ responseStatus: /^5\d{2}$/ });

// Generate analytics
const analytics = await advanced.generateAnalytics({ 
  start: '2025-01-01T00:00:00Z', 
  end: '2025-01-31T23:59:59Z' 
});

Multi-Service CLI

# Start specific services
npm run service:api       # REST API server
npm run service:kafka     # Kafka consumer
npm run service:websocket # WebSocket server
npm run service:multi     # All services

# With custom options
node examples/multi-service-cli.js api --port 4000
node examples/multi-service-cli.js kafka --brokers localhost:9092

⚙️ Configuration

Basic Configuration

await logstack.init({
  dbUri: 'mongodb://localhost:27017/myapp',
  uploadProvider: 's3',
  outputDirectory: 'production-logs',
  
  // S3 Configuration
  s3: {
    accessKeyId: process.env.AWS_ACCESS_KEY_ID,
    secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY,
    region: 'us-east-1',
    bucket: 'my-logs-bucket'
  },
  
  // Security & Performance
  compression: { enabled: true },
  dataMasking: { enabled: true, fields: ['password', 'token'] },
  retention: { enabled: true, days: 90 }
});

Framework Integration

Express.js

const express = require('express');
const logstack = require('logstack');

const app = express();
await logstack.init(config);

// Automatic API logging middleware
app.use(async (req, res, next) => {
  const start = new Date();
  res.on('finish', async () => {
    await logstack.saveApiLog({
      method: req.method,
      path: req.path,
      responseStatus: res.statusCode,
      request_time: start,
      response_time: new Date()
    });
  });
  next();
});
