# Referencia del SDK de base de datos

> Operaciones de base de datos de tipo seguro con el SDK de Swift de InsForge

## Instalación

Add InsForge to your Swift Package Manager dependencies:

```swift theme={null}
dependencies: [
    .package(url: "https://github.com/insforge/insforge-swift.git", from: "0.0.9")
]
```

```swift theme={null}
import InsForge

let insforge = InsForgeClient(
    baseURL: URL(string: "https://your-app.insforge.app")!,
    anonKey: "your-anon-key"
)
```

### Enable Logging (Optional)

For debugging, you can configure the SDK log level and destination:

```swift theme={null}
let options = InsForgeClientOptions(
    global: .init(
        logLevel: .debug,
        logDestination: .osLog,
        logSubsystem: "com.example.MyApp"
    )
)

let insforge = InsForgeClient(
    baseURL: URL(string: "https://your-app.insforge.app")!,
    anonKey: "your-anon-key",
    options: options
)
```

**Log Levels:**

| Level       | Description                                 |
| ----------- | ------------------------------------------- |
| `.trace`    | Most verbose, includes all internal details |
| `.debug`    | Detailed information for debugging          |
| `.info`     | General operational information (default)   |
| `.warning`  | Warnings that don't prevent operation       |
| `.error`    | Errors that affect functionality            |
| `.critical` | Critical failures                           |

**Log Destinations:**

| Destination | Description                                                |
| ----------- | ---------------------------------------------------------- |
| `.console`  | Standard output (print)                                    |
| `.osLog`    | Apple's unified logging system (recommended for iOS/macOS) |
| `.none`     | Disable logging                                            |
| `.custom`   | Provide your own LogHandler factory                        |

<Note>
  Use `.info` or `.error` in production to avoid exposing sensitive data in logs.
</Note>

## Definir modelos

Defina sus modelos de datos usando el protocolo `Codable` de Swift:

```swift theme={null}
struct Post: Codable {
    let id: String?
    let title: String
    let content: String
    let userId: String
    let createdAt: Date?
}
```

***

## insert()

Inserte nuevos registros en una tabla.

### Parámetros

* `values` - Objeto Codable único o matriz de objetos para insertar

### Ejemplos

```swift theme={null}
// Single insert
let post = Post(
    id: nil,
    title: "Hello World",
    content: "My first post!",
    userId: currentUserId,
    createdAt: nil
)
let inserted = try await insforge.database
    .from("posts")
    .insert(post)

// Bulk insert
let posts = [
    Post(id: nil, title: "First Post", content: "Hello everyone!", userId: currentUserId, createdAt: nil),
    Post(id: nil, title: "Second Post", content: "Another update.", userId: currentUserId, createdAt: nil)
]
let inserted = try await insforge.database
    .from("posts")
    .insert(posts)
```

***

## update()

Actualizar registros existentes en una tabla.

### Ejemplos

```swift theme={null}
// Define update model
struct PostUpdate: Codable {
    let title: String
}

// Update by ID
let updated: [Post] = try await insforge.database
    .from("posts")
    .eq("id", value: postId)
    .update(PostUpdate(title: "Updated Title"))

// Update multiple records
struct TaskUpdate: Codable {
    let status: String
}

let updated: [Task] = try await insforge.database
    .from("tasks")
    .in("id", values: ["task-1", "task-2"])
    .update(TaskUpdate(status: "completed"))
```

***

## delete()

Eliminar registros de una tabla.

### Ejemplos

```swift theme={null}
// Delete by ID
try await insforge.database
    .from("posts")
    .eq("id", value: postId)
    .delete()

// Delete with filter
try await insforge.database
    .from("sessions")
    .lt("expires_at", value: Date())
    .delete()
```

***

## select()

Consultar registros de una tabla.

### Ejemplos

```swift theme={null}
// Get all posts
let posts: [Post] = try await insforge.database
    .from("posts")
    .select()
    .execute()

// Filter and sort
let recentPosts: [Post] = try await insforge.database
    .from("posts")
    .select()
    .eq("userId", value: currentUserId)
    .order("createdAt", ascending: false)
    .limit(20)
    .execute()

// Multiple filters
let activePosts: [Post] = try await insforge.database
    .from("posts")
    .select()
    .eq("userId", value: currentUserId)
    .eq("status", value: "published")
    .execute()

// Specific columns
let posts = try await insforge.database
    .from("posts")
    .select("id, title, content")
    .execute()

// With relationships
let posts = try await insforge.database
    .from("posts")
    .select("*, comments(id, content)")
    .execute()
```

***

## rpc()

Llamar a funciones PostgreSQL almacenadas (RPC - Remote Procedure Call). Este método le permite invocar directamente funciones SQL definidas en su base de datos.

### Parámetros

* `functionName` (String) - Nombre de la función PostgreSQL a llamar
* `args` (\[String: Any]?, optional) - Argumentos para pasar a la función

### Ejemplos

```swift theme={null}
// Define response models
struct UserStats: Decodable {
    let totalPosts: Int
    let totalComments: Int
}

struct User: Decodable {
    let id: String
    let name: String
    let email: String
}

// Call function with parameters, returning array
let stats: [UserStats] = try await insforge.database
    .rpc("get_user_stats", args: ["user_id": "123"])
    .execute()

// Call function with parameters, returning single result
let stat: UserStats = try await insforge.database
    .rpc("get_user_stats", args: ["user_id": "123"])
    .executeSingle()

// Call function without parameters
let users: [User] = try await insforge.database
    .rpc("get_all_active_users")
    .execute()

// Call function with multiple parameters
let results: [Post] = try await insforge.database
    .rpc("search_posts", args: [
        "search_term": "swift",
        "limit": 10,
        "offset": 0
    ])
    .execute()

// Call function with no return value (void function)
try await insforge.database
    .rpc("cleanup_old_records", args: ["days": 30])
    .execute()

// Call function returning a single primitive value
let count: Int = try await insforge.database
    .rpc("count_active_posts")
    .executeSingle()
```

### Detalles de implementación

* **Sin argumentos**: Utiliza la solicitud GET a `/api/database/rpc/{functionName}`
* **Con argumentos**: Utiliza la solicitud POST con cuerpo JSON a `/api/database/rpc/{functionName}`
* Use `execute()` para funciones que devuelven matrices o void
* Use `executeSingle()` para funciones que devuelven un solo objeto o valor
