| * 🚀 Core Architecture: Safe API Calling with Koin & Coroutines | |
| * Stack: Kotlin | Koin | Flow | Result Pattern | |
| * Author: Trinadh Thatakula | |

| // 1. type-safe Result wrapper | |
| sealed interface DataResult<out T> { | |
| data class Success<T>(val data: T) : DataResult<T> | |
| data class Error(val exception: Throwable, val message: String? = null) : DataResult<Nothing> | |
| data object Loading : DataResult<Nothing> | |
| } | |
| // 2. The Extension Function | |
| // Safely executes a network call and catches exceptions automatically | |
| suspend fun <T> safeApiCall( | |
| dispatcher: CoroutineDispatcher = Dispatchers.IO, | |
| apiCall: suspend () -> T | |
| ): DataResult<T> = withContext(dispatcher) { | |
| try { | |
| DataResult.Success(apiCall()) | |
| } catch (e: Exception) { | |
| // Log to Crashlytics/Loki here | |
| DataResult.Error(e, e.localizedMessage ?: "Unknown Error") | |
| } | |
| } | |
| // 3. Koin Module Definition | |
| val networkModule = module { | |
| single { | |
| HttpClient(Android) { | |
| install(ContentNegotiation) { json() } | |
| install(Logging) { level = LogLevel.ALL } | |
| } | |
| } | |
| // Injecting the Repository with the safe caller | |
| factory<AuthRepository> { AuthRepositoryImpl(client = get()) } | |
| } |
