資料庫 SDK 參考 - InsForge Docs

安裝

Add InsForge to your Swift Package Manager dependencies:

dependencies: [
    .package(url: "https://github.com/insforge/insforge-swift.git", from: "0.0.9")
]

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:

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

Use .info or .error in production to avoid exposing sensitive data in logs.

定義模型

使用 Swift 的 Codable 通訊協定定義資料模型：

struct Post: Codable {
    let id: String?
    let title: String
    let content: String
    let userId: String
    let createdAt: Date?
}

insert()

將新記錄插入到資料表中。

參數

values - 單個 Codable 物件或要插入的物件陣列

範例

// 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()

更新資料表中的現有記錄。

範例

// 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()

從資料表中刪除記錄。

範例

// 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()

從資料表查詢記錄。

範例

// 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()

呼叫 PostgreSQL 預存程式（RPC - 遠端程序呼叫）。此方法可讓您直接叫用在資料庫中定義的 SQL 函數。

參數

functionName (String) - 要呼叫的 PostgreSQL 函數名稱
args ([String: Any]?, optional) - 要傳遞給函數的引數

範例

// 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()

實作詳細資料

無引數：使用 GET 要求至 /api/database/rpc/{functionName}
含引數：使用 POST 要求搭配 JSON 主體至 /api/database/rpc/{functionName}
對於傳回陣列或 void 的函數，使用 execute()
對於傳回單一物件或值的函數，使用 executeSingle()
