## 🚀 Quick Start (Copy-Paste Ready)

### Basic Node.js Implementation

```javascript
const {
  init,
  createDailyJobs,
  processSpecificHour,
} = require("logstack");

const config = {
  dbUri: "mongodb://localhost:27017/myapp",
  uploadProvider: "local",
  fileFormat: "json",

  // ✨ Organized files (not in project root)
  outputDirectory: "api-logs",

  // ✨ Custom collections (no conflicts)
  collections: {
    jobsCollectionName: "myapp_jobs",
    logsCollectionName: "myapp_logs",
  },

  logging: {
    level: "info",
    enableConsole: true,
  },
};

async function startCronService() {
  try {
    await init(config);
    console.log("✅ Cron service initialized");
    console.log("📁 Files saved to: ./api-logs/");
    console.log("🗃️ Collections: myapp_jobs, myapp_logs");
  } catch (error) {
    console.error("❌ Failed to initialize:", error);
  }
}

startCronService();
```

### Express.js Integration

```javascript
const express = require("express");
const { init, setupRequestLogging } = require("logstack");

const app = express();

const cronConfig = {
  dbUri: "mongodb://localhost:27017/myapp",
  uploadProvider: "local",
  outputDirectory: "api-logs",
  collections: {
    jobsCollectionName: "api_jobs",
    logsCollectionName: "api_logs",
  },
};

async function startServer() {
  // Initialize cron service
  await init(cronConfig);

  // Add automatic request logging
  app.use(setupRequestLogging(cronConfig));

  // Your API routes
  app.get("/api/users", (req, res) => {
    res.json({ users: [] }); // Automatically logged
  });

  app.listen(3000, () => {
    console.log("🚀 Server running on port 3000");
    console.log("📁 API logs saved to: ./api-logs/");
  });
}

startServer();
```

## 🎯 Key Features Implementation

### ✅ Custom Collection Names (Solves Database Conflicts)

```javascript
// Problem: Multiple services using same database
// Solution: Custom collection names

const userServiceConfig = {
  collections: {
    jobsCollectionName: "user_service_jobs",
    logsCollectionName: "user_service_logs",
  },
};

const orderServiceConfig = {
  collections: {
    jobsCollectionName: "order_service_jobs",
    logsCollectionName: "order_service_logs",
  },
};
```

### ✅ Organized Output Directory (Clean Project Structure)

```javascript
// Problem: Date folders cluttering project root
// Solution: Organized output directory

const config = {
  outputDirectory: "api-logs", // All files go here
  // Before: ./2025-08-25/14-15.json (messy root)
  // After:  ./api-logs/2025-08-25/14-15.json (organized)
};
```

## 📦 Installation & Setup

### Step 1: Install Package

```bash
npm install logstack
```

### Step 2: Basic Setup

Create `cron-service.js`:

```javascript
const { init } = require("logstack");

const config = {
  dbUri: "mongodb://localhost:27017/YOUR_APP_NAME",
  uploadProvider: "local",
  outputDirectory: "YOUR_APP_NAME-logs",
  collections: {
    jobsCollectionName: "YOUR_APP_NAME_jobs",
    logsCollectionName: "YOUR_APP_NAME_logs",
  },
};

async function startCronService() {
  await init(config);
  console.log("✅ Cron service ready!");
}

startCronService();
```

### Step 3: Run Your App

```bash
node cron-service.js
```

---


## 🌍 Environment-Based Configuration

### Development Setup

```javascript
// development.js
const devConfig = {
  dbUri: "mongodb://localhost:27017/myapp_dev",
  uploadProvider: "local",
  outputDirectory: "dev-logs",
  collections: {
    jobsCollectionName: "dev_jobs",
    logsCollectionName: "dev_logs",
  },
};
```

### Production Setup

```javascript
// production.js
const prodConfig = {
  dbUri: process.env.PROD_DB_URI,
  uploadProvider: "s3",
  outputDirectory: "production-logs",
  collections: {
    jobsCollectionName: "prod_jobs",
    logsCollectionName: "prod_logs",
  },
  s3: {
    accessKeyId: process.env.AWS_ACCESS_KEY_ID,
    secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY,
    region: "us-east-1",
    bucket: "company-logs",
  },
};
```

---


## 🧪 Testing Your Implementation

```javascript
const {
  init,
  createDailyJobs,
  processSpecificHour,
} = require("logstack");

async function testImplementation() {
  const testConfig = {
    dbUri: "mongodb://localhost:27017/test",
    uploadProvider: "local",
    outputDirectory: "test-logs",
    collections: {
      jobsCollectionName: "test_jobs",
      logsCollectionName: "test_logs",
    },
  };

  try {
    // Test initialization
    await init(testConfig);
    console.log("✅ Service initialized");

    // Test job creation
    const job = await createDailyJobs("2025-08-25", testConfig);
    console.log(`✅ Created ${job.hours.length} hour slots`);

    // Test processing
    await processSpecificHour("2025-08-25", 14, testConfig);
    console.log("✅ Processed hour 14-15");
    console.log("📁 Check: ./test-logs/2025-08-25/14-15.json");

    console.log("🎉 All tests passed!");
  } catch (error) {
    console.error("❌ Test failed:", error);
  }
}

testImplementation();
```
