Uses `ImmutableList` from kotlinx.collections.immutable instead of `List`. Uses `FormField` for form validation. -- **Action**: `@Immutable` sealed interface. Uses `data object` for simple actions, `data class` for parameterized ones. Can nest sub-sealed interfaces for grouping (e.g., `PersonAction.NewPerson`, `PersonAction.LoadedPerson`). -- **ViewModel**: Exposes `StateFlow` and a single `onAction(Action)` function. Uses `viewModelScope` for coroutines. Navigation via injected `NavigationService`. +## Subscriptions -#### Files per Feature +### SQL-string subscriptions -``` -person/ -├── domain/ -│ ├── model/Person.kt -│ └── repository/PersonRepository.kt -├── data/ -│ ├── PersonRepositoryImpl.kt -│ ├── database/PersonDao.kt, PersonEntity.kt, PersonDatabase.kt -│ ├── rpc/PersonRpcClient.kt -│ └── mapper/PersonMapper.kt -└── presentation/ - ├── PersonScreen.kt # Screen() + Content() - ├── PersonState.kt # @Immutable data class - ├── PersonAction.kt # @Immutable sealed interface - ├── PersonViewModel.kt # ViewModel with StateFlow + onAction - └── mapper/PersonMapper.kt # Domain ↔ Form mappers +```kotlin +// Subscribe to all rows +conn.subscribe("SELECT person.* FROM person") + +// Multiple queries +conn.subscribe( + "SELECT person.* FROM person", + "SELECT item.* FROM item", +) ``` -Previews live in a shared `Preview.kt` file using `Content()` with mock state. +### Type-safe query builder -### Navigation Architecture - -This template uses a **NavigationService** pattern for clean, testable, and scalable navigation: +```kotlin +conn.subscriptionBuilder() + .addQuery { qb -> qb.person() } // all rows + .addQuery { qb -> qb.person().where { c -> c.name.eq("Alice") } } // filtered + .onApplied { ctx -> println("Subscription applied") } + .onError { ctx, err -> println("Subscription error: $err") } + .subscribe() +``` -#### NavigationService - Injectable Singleton +## Table Callbacks ```kotlin -class NavigationService { - fun to(route: Route) // Navigate to route - fun back() // Navigate back - fun toAndClearUpTo(route, clearUpTo) // Clear back stack - fun toAndClearAll(route) // Reset navigation -} +// Fires for each inserted row +conn.db.person.onInsert { ctx, person -> } + +// Fires for each deleted row (persistent tables only) +conn.db.person.onDelete { ctx, person -> } + +// Fires before delete (useful for cleanup/animation triggers) +conn.db.person.onBeforeDelete { ctx, person -> } ``` -#### ViewModel Usage +Remove callbacks by passing the same function reference to the corresponding `removeOn*` method. -ViewModels inject `NavigationService` and use simple API calls: +## Reading Table Data ```kotlin -class HomeViewModel( - private val nav: NavigationService, // Injected via Koin -) : ViewModel() { - fun onAction(action: HomeAction) { - when (action) { - HomeAction.OnPersonClicked -> nav.to(Route.Person) - } - } -} +// All cached rows +val people: List = conn.db.person.all() + +// Row count +val count: Int = conn.db.person.count() + +// Lazy iteration +conn.db.person.iter().forEach { person -> println(person.name) } ``` -#### App Setup +## One-Off Queries -Use `NavigationHost` wrapper that auto-observes NavigationService: +Execute a query outside of subscriptions: ```kotlin -@Composable -fun AppReady() { - NavigationHost( - navController = rememberNavController(), - startDestination = Route.Graph, - ) { - navigation(startDestination = Route.Home) { - composable { HomeScreen() } - composable { PersonScreen() } - } - } -} -``` +// Callback-based +conn.oneOffQuery("SELECT person.* FROM person") { result -> } -#### Benefits +// Suspend (with optional timeout) +val result = conn.oneOffQuery("SELECT person.* FROM person", timeout = 5.seconds) -- **Simple API**: `nav.to(route)` instead of manual effect management -- **Testable**: Easy to mock NavigationService in unit tests -- **Centralized**: Add analytics, guards, deep links in one place -- **No Boilerplate**: No LaunchedEffect, callbacks, or when expressions -- **True MVI**: Pure unidirectional data flow maintained +// Table-level convenience +conn.db.person.remoteQuery("WHERE name = 'Alice'") { people -> } +val people = conn.db.person.remoteQuery("WHERE name = 'Alice'") // suspend +``` -### Configuration +## Thread Safety -App configuration uses TOML files following XDG Base Directory conventions (e.g., `~/.config/spacetimedb_kotlin_sdk/app.toml`). Each `Config` implements `toToml()` to produce commented output, so programmatic saves preserve inline documentation. +The SDK is safe to use from any thread/coroutine: -#### AppConfigProvider — Runtime Config +- **Client cache**: All row storage uses atomic references over persistent immutable collections (`kotlinx.collections.immutable`). No locks are needed — each reader gets a consistent snapshot via atomic reference reads. +- **Callback lists**: Stored as atomic `PersistentList` references. Adding/removing callbacks and iterating over them are lock-free operations. +- **Connection state**: Managed via atomic compare-and-swap, preventing double-connect or double-disconnect races. -`AppConfigProvider` holds the current config as a `StateFlow`, loaded eagerly at startup via `AppConfigProviderFactory` with Koin's `createdAtStart = true`. Config changes are applied via `updateConfig()`, which persists to disk and triggers downstream service reactions: +### Callback Dispatcher -- **Logger**: `Log.reconfigure()` applies new log level, format, and file settings immediately -- **RPC Client**: `PersonRpcClient` uses a check-on-use pattern — compares `ServerConnectionConfig` before each call and reconnects if host/port changed +By default, callbacks execute on the WebSocket receive coroutine. To dispatch callbacks on a specific thread (e.g., the main/UI thread): ```kotlin -// Example: changing log level at runtime -appConfigProvider.updateConfig { config -> - config.copy(logging = config.logging.copy(level = LogLevel.ERROR)) -} -// Logger is reconfigured, config is persisted to app.toml +DbConnection.Builder() + .withCallbackDispatcher(Dispatchers.Main) + // ... + .build() ``` -#### Check-on-Use Pattern +This applies to all table, reducer, subscription, and connection callbacks. -Services that depend on config use a check-on-use pattern: cache the connection and the config snapshot, compare before each call, and recreate if changed. This avoids flow observation and keeps the logic colocated. +## Dependencies -```kotlin -class PersonRpcClient( - private val ktorClient: HttpClient, - private val appConfigProvider: AppConfigProvider, -) { -
