## Overview

Orama Network provides a decentralized platform for deploying web applications and managing databases. Each deployment:

- **Gets a unique domain** automatically (e.g., `myapp.orama.network`)
- **Isolated per namespace** - your data and apps are completely separate from others
- **Served from IPFS** (static) or **runs as a process** (dynamic apps)
- **Fully managed** - automatic health checks, restarts, and logging

### Supported Deployment Types

| Type | Description | Use Case | Domain Example |
|------|-------------|----------|----------------|
| **Static** | HTML/CSS/JS files served from IPFS | React, Vue, Angular, plain HTML | `myapp.orama.network` |
| **Next.js** | Next.js with SSR support | Full-stack Next.js apps | `myapp.orama.network` |
| **Go** | Compiled Go binaries | REST APIs, microservices | `api.orama.network` |
| **Node.js** | Node.js applications | Express APIs, TypeScript backends | `backend.orama.network` |

---

## Authentication

Before deploying, authenticate with your wallet:

```bash
# Authenticate
orama auth login

# Check authentication status
orama auth whoami
```

Your API key is stored securely and used for all deployment operations.

---

## Deploying Static Sites

Deploy static sites built with React, Vue, Angular, or any static site generator.

### React/Vite Example

```bash
# 1. Build your React app
cd my-react-app
npm run build

# 2. Deploy the build directory
orama deploy static ./dist --name my-react-app --domain repoanalyzer.ai

# Output:
# 📦 Creating tarball from ./dist...
# ☁️  Uploading to Orama Network...
#
# ✅ Deployment successful!
#
# Name:         my-react-app
# Type:         static
# Status:       active
# Version:      1
# Content CID:  QmXxxx...
#
# URLs:
#   • https://my-react-app.orama.network
```

### What Happens Behind the Scenes

1. **Tarball Creation**: CLI automatically creates a `.tar.gz` from your directory
2. **IPFS Upload**: Files are uploaded to IPFS and pinned across the network
3. **DNS Record**: A DNS record is created pointing `my-react-app.orama.network` to the gateway
4. **Instant Serving**: Your app is immediately accessible via the URL

### Features

- ✅ **SPA Routing**: Unknown routes automatically serve `/index.html` (perfect for React Router)
- ✅ **Correct Content-Types**: Automatically detects and serves `.html`, `.css`, `.js`, `.json`, `.png`, etc.
- ✅ **Caching**: `Cache-Control: public, max-age=3600` headers for optimal performance
- ✅ **Zero Downtime Updates**: Use `--update` flag to update without downtime

### Updating a Deployment

```bash
# Make changes to your app
# Rebuild
npm run build

# Update deployment
orama deploy static ./dist --name my-react-app --update

# Version increments automatically (1 → 2)
```

---

## Deploying Next.js Applications

Deploy Next.js apps with full SSR (Server-Side Rendering) support.

### Next.js with SSR

```bash
# 1. Build your Next.js app
cd my-nextjs-app
npm run build

# 2. Deploy with SSR enabled
orama deploy nextjs . --name my-nextjs --ssr

# Output:
# 📦 Creating tarball from .
# ☁️  Uploading to Orama Network...
#
# ✅ Deployment successful!
#
# Name:         my-nextjs
# Type:         nextjs
# Status:       active
# Version:      1
# Port:         10100
#
# URLs:
#   • https://my-nextjs.orama.network
#
# ⚠️  Note: SSR deployment may take a minute to start. Check status with: orama deployments get my-nextjs
```

### What Happens Behind the Scenes

1. **Tarball Upload**: Your `.next` build directory, `package.json`, and `public` are uploaded
2. **Home Node Assignment**: A node is chosen to host your app based on capacity
3. **Port Allocation**: A unique port (10100-19999) is assigned
4. **Systemd Service**: A systemd service is created to run `node server.js`
5. **Health Checks**: Gateway monitors your app every 30 seconds
6. **Reverse Proxy**: Gateway proxies requests from your domain to the local port

### Static Next.js Export (No SSR)

If you export Next.js to static HTML:

```bash
# next.config.js
module.exports = {
  output: 'export'
}

# Build and deploy as static
npm run build
orama deploy static ./out --name my-nextjs-static
```

---

## Deploying Go Backends

Deploy compiled Go binaries for high-performance APIs.

### Go REST API Example

```bash
# 1. Build your Go binary for Linux (if on Mac/Windows)
cd my-go-api
GOOS=linux GOARCH=amd64 go build -o api main.go

# 2. Deploy the binary
orama deploy go ./api --name my-api

# Output:
# 📦 Creating tarball from ./api...
# ☁️  Uploading to Orama Network...
#
# ✅ Deployment successful!
#
# Name:         my-api
# Type:         go
# Status:       active
# Version:      1
# Port:         10101
#
# URLs:
#   • https://my-api.orama.network
```

### Example Go API Code

```go
// main.go
package main

import (
    "encoding/json"
    "log"
    "net/http"
    "os"
)

func main() {
    port := os.Getenv("PORT")
    if port == "" {
        port = "8080"
    }

    http.HandleFunc("/health", func(w http.ResponseWriter, r *http.Request) {
        json.NewEncoder(w).Encode(map[string]string{"status": "healthy"})
    })

    http.HandleFunc("/api/users", func(w http.ResponseWriter, r *http.Request) {
        users := []map[string]interface{}{
            {"id": 1, "name": "Alice"},
            {"id": 2, "name": "Bob"},
        }
        json.NewEncoder(w).Encode(users)
    })

    log.Printf("Starting server on port %s", port)
    log.Fatal(http.ListenAndServe(":"+port, nil))
}
```

### Important Notes

- **Environment Variables**: The `PORT` environment variable is automatically set to your allocated port
- **Health Endpoint**: Recommended to implement `/health` for monitoring
- **Binary Requirements**: Must be Linux-compatible (GOOS=linux GOARCH=amd64)
- **Systemd Managed**: Runs as a systemd service with auto-restart on failure

---

## Deploying Node.js Backends

Deploy Node.js/Express/TypeScript backends.

### Express API Example

```bash
# 1. Build your Node.js app (if using TypeScript)
cd my-node-api
npm run build

# 2. Deploy (must include node_modules or use a bundler)
orama deploy nodejs ./dist --name my-node-api

# Output:
# 📦 Creating tarball from ./dist...
# ☁️  Uploading to Orama Network...
#
# ✅ Deployment successful!
#
# Name:         my-node-api
# Type:         nodejs
# Status:       active
# Version:      1
# Port:         10102
#
# URLs:
#   • https://my-node-api.orama.network
```

### Example Node.js API

```javascript
// server.js
const express = require('express');
const app = express();
const port = process.env.PORT || 8080;

app.get('/health', (req, res) => {
  res.json({ status: 'healthy' });
});

app.get('/api/data', (req, res) => {
  res.json({ message: 'Hello from Orama Network!' });
});

app.listen(port, () => {
  console.log(`Server running on port ${port}`);
});
```

## Managing SQLite Databases

Each namespace gets its own isolated SQLite databases.

### Creating a Database

```bash
# Create a new database
orama db create my-database

# Output:
# ✅ Database created: my-database
# Home Node: node-abc123
# File Path: /home/debros/.orama/data/sqlite/your-namespace/my-database.db
```

### Executing Queries

```bash
# Create a table
orama db query my-database "CREATE TABLE users (id INTEGER PRIMARY KEY, name TEXT, email TEXT)"

# Insert data
orama db query my-database "INSERT INTO users (name, email) VALUES ('Alice', 'alice@example.com')"

# Query data
orama db query my-database "SELECT * FROM users"

# Output:
# 📊 Query Result
# Rows: 1
#
# id              | name            | email
# ----------------+-----------------+-------------------------
# 1               | Alice           | alice@example.com
```

### Listing Databases

```bash
orama db list

# Output:
# NAME              SIZE        HOME NODE       CREATED
# my-database       12.3 KB     node-abc123     2024-01-22 10:30
# prod-database     1.2 MB      node-abc123     2024-01-20 09:15
#
# Total: 2
```

### Backing Up to IPFS

```bash
# Create a backup
orama db backup my-database

# Output:
# ✅ Backup created
# CID: QmYxxx...
# Size: 12.3 KB

# List backups
orama db backups my-database

# Output:
# VERSION    CID               SIZE        DATE
# 1          QmYxxx...         12.3 KB     2024-01-22 10:45
# 2          QmZxxx...         15.1 KB     2024-01-22 14:20
```

### Database Features

- ✅ **WAL Mode**: Write-Ahead Logging for better concurrency
- ✅ **Namespace Isolation**: Complete separation between namespaces
- ✅ **Automatic Backups**: Scheduled backups to IPFS every 6 hours
- ✅ **ACID Transactions**: Full SQLite transactional support
- ✅ **Concurrent Reads**: Multiple readers can query simultaneously

---

## How Domains Work

### Domain Assignment

When you deploy an application, it automatically gets a domain:

```
Format: {deployment-name}.orama.network
Example: my-react-app.orama.network
```

### Node-Specific Domains (Optional)

For direct access to a specific node:

```
Format: {deployment-name}.{node-id}.orama.network
Example: my-react-app.node-7prvNa.orama.network
```

### DNS Resolution Flow

1. **Client**: Browser requests `my-react-app.orama.network`
2. **DNS**: CoreDNS server queries RQLite for DNS record
3. **Record**: Returns IP address of a gateway node
4. **Gateway**: Receives request with `Host: my-react-app.orama.network` header
5. **Routing**: Domain routing middleware looks up deployment by domain
6. **Response**:
   - **Static**: Serves content from IPFS
   - **Dynamic**: Reverse proxies to the app's local port

### Custom Domains (Future Feature)

Support for custom domains (e.g., `www.myapp.com`) with TXT record verification.

---

## Full-Stack Application Example

Deploy a complete full-stack application with React frontend, Go backend, and SQLite database.

```

### Step 1: Create the Database

```bash
# Create database
orama db create myapp-db

# Create schema
orama db query myapp-db "CREATE TABLE users (
    id INTEGER PRIMARY KEY AUTOINCREMENT,
    name TEXT NOT NULL,
    email TEXT UNIQUE NOT NULL,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
)"

# Insert test data
orama db query myapp-db "INSERT INTO users (name, email) VALUES ('Alice', 'alice@example.com')"
```

### Step 2: Deploy Go Backend

**Backend Code** (`main.go`):

```go
package main

import (
    "database/sql"
    "encoding/json"
    "log"
    "net/http"
    "os"

    _ "github.com/mattn/go-sqlite3"
)

type User struct {
    ID        int    `json:"id"`
    Name      string `json:"name"`
    Email     string `json:"email"`
    CreatedAt string `json:"created_at"`
}

var db *sql.DB

func main() {
    // DATABASE_NAME env var is automatically set by Orama
    dbPath := os.Getenv("DATABASE_PATH")
    if dbPath == "" {
        dbPath = "/home/debros/.orama/data/sqlite/" + os.Getenv("NAMESPACE") + "/myapp-db.db"
    }

    var err error
    db, err = sql.Open("sqlite3", dbPath)
    if err != nil {
        log.Fatal(err)
    }
    defer db.Close()

    port := os.Getenv("PORT")
    if port == "" {
        port = "8080"
    }

    // CORS middleware
    http.HandleFunc("/", corsMiddleware(routes))

    log.Printf("Starting server on port %s", port)
    log.Fatal(http.ListenAndServe(":"+port, nil))
}

func routes(w http.ResponseWriter, r *http.Request) {
    switch r.URL.Path {
    case "/health":
        json.NewEncoder(w).Encode(map[string]string{"status": "healthy"})
    case "/api/users":
        if r.Method == "GET" {
            getUsers(w, r)
        } else if r.Method == "POST" {
            createUser(w, r)
        }
    default:
        http.NotFound(w, r)
    }
}

func getUsers(w http.ResponseWriter, r *http.Request) {
    rows, err := db.Query("SELECT id, name, email, created_at FROM users ORDER BY id")
    if err != nil {
        http.Error(w, err.Error(), http.StatusInternalServerError)
        return
    }
    defer rows.Close()

    var users []User
    for rows.Next() {
        var u User
        rows.Scan(&u.ID, &u.Name, &u.Email, &u.CreatedAt)
        users = append(users, u)
    }

    w.Header().Set("Content-Type", "application/json")
    json.NewEncoder(w).Encode(users)
}

func createUser(w http.ResponseWriter, r *http.Request) {
    var u User
    if err := json.NewDecoder(r.Body).Decode(&u); err != nil {
        http.Error(w, err.Error(), http.StatusBadRequest)
        return
    }

    result, err := db.Exec("INSERT INTO users (name, email) VALUES (?, ?)", u.Name, u.Email)
    if err != nil {
        http.Error(w, err.Error(), http.StatusInternalServerError)
        return
    }

    id, _ := result.LastInsertId()
    u.ID = int(id)

    w.Header().Set("Content-Type", "application/json")
    w.WriteHeader(http.StatusCreated)
    json.NewEncoder(w).Encode(u)
}

func corsMiddleware(next http.HandlerFunc) http.HandlerFunc {
    return func(w http.ResponseWriter, r *http.Request) {
        w.Header().Set("Access-Control-Allow-Origin", "*")
        w.Header().Set("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS")
        w.Header().Set("Access-Control-Allow-Headers", "Content-Type, Authorization")

        if r.Method == "OPTIONS" {
            w.WriteHeader(http.StatusOK)
            return
        }

        next(w, r)
    }
}
```

**Deploy Backend**:

```bash
# Build for Linux
GOOS=linux GOARCH=amd64 go build -o api main.go

# Deploy
orama deploy go ./api --name myapp-api
```

### Step 3: Deploy React Frontend

**Frontend Code** (`src/App.jsx`):

```jsx
import { useEffect, useState } from 'react';

function App() {
  const [users, setUsers] = useState([]);
  const [name, setName] = useState('');
  const [email, setEmail] = useState('');

  const API_URL = 'https://myapp-api.orama.network';

  useEffect(() => {
    fetchUsers();
  }, []);

  const fetchUsers = async () => {
    const response = await fetch(`${API_URL}/api/users`);
    const data = await response.json();
    setUsers(data);
  };

  const addUser = async (e) => {
    e.preventDefault();
    await fetch(`${API_URL}/api/users`, {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify({ name, email }),
    });
    setName('');
    setEmail('');
    fetchUsers();
  };

  return (
    <div>
      <h1>Orama Network Full-Stack App</h1>

      <h2>Add User</h2>
      <form onSubmit={addUser}>
        <input
          value={name}
          onChange={(e) => setName(e.target.value)}
          placeholder="Name"
          required
        />
        <input
          value={email}
          onChange={(e) => setEmail(e.target.value)}
          placeholder="Email"
          type="email"
          required
        />
        <button type="submit">Add User</button>
      </form>

      <h2>Users</h2>
      <ul>
        {users.map((user) => (
          <li key={user.id}>
            {user.name} - {user.email}
          </li>
        ))}
      </ul>
    </div>
  );
}

export default App;
```

**Deploy Frontend**:

```bash
# Build
npm run build

# Deploy
orama deploy static ./dist --name myapp
```

### Step 4: Access Your App

Open your browser to:
- **Frontend**: `https://myapp.orama.network`
- **Backend API**: `https://myapp-api.orama.network/api/users`

### Full-Stack Summary

✅ **Frontend**: React app served from IPFS
✅ **Backend**: Go API running on allocated port
✅ **Database**: SQLite database with ACID transactions
✅ **Domains**: Automatic DNS for both services
✅ **Isolated**: All resources namespaced and secure

## Troubleshooting

### Deployment Issues

**Problem**: Deployment status is "failed"

```bash
# Check deployment details
orama deployments get my-app

# View logs for errors
orama deployments logs my-app

# Common issues:
# - Binary not compiled for Linux (GOOS=linux GOARCH=amd64)
# - Missing dependencies (node_modules not included)
# - Port already in use (shouldn't happen, but check logs)
# - Health check failing (ensure /health endpoint exists)
```

**Problem**: Can't access deployment URL

```bash
# 1. Check deployment status
orama deployments get my-app

# 2. Verify DNS (may take up to 10 seconds to propagate)
dig my-app.orama.network

# 3. For local development, add to /etc/hosts
echo "127.0.0.1 my-app.orama.network" | sudo tee -a /etc/hosts

# 4. Test with Host header
curl -H "Host: my-app.orama.network" http://localhost:6001/
```

### Database Issues

**Problem**: Database not found

```bash
# List all databases
orama db list

# Ensure database name matches exactly (case-sensitive)
# Databases are namespace-isolated
```

**Problem**: SQL query fails

```bash
# Check table exists
orama db query my-db "SELECT name FROM sqlite_master WHERE type='table'"

# Check syntax
orama db query my-db ".schema users"
```

### Authentication Issues

```bash
# Re-authenticate
orama auth logout
orama auth login

# Check token validity
orama auth status
```

## Best Practices

### Security

1. **Never commit sensitive data**: Use environment variables for secrets
2. **Validate inputs**: Always sanitize user input in your backend
3. **HTTPS only**: All deployments automatically use HTTPS in production
4. **CORS**: Configure CORS appropriately for your API

### Performance

1. **Optimize builds**: Minimize bundle sizes (React, Next.js)
2. **Use caching**: Leverage browser caching for static assets
3. **Database indexes**: Add indexes to frequently queried columns
4. **Health checks**: Implement `/health` endpoint for monitoring

### Deployment Workflow

1. **Test locally first**: Ensure your app works before deploying
2. **Use version control**: Track changes in Git
3. **Incremental updates**: Use `--update` flag instead of delete + redeploy
4. **Backup databases**: Regular backups via `orama db backup`
5. **Monitor logs**: Check logs after deployment for errors

---
