MVVMate

MVVMate is a minimal state management library for Compose Multiplatform, based on the MVVM architecture.

Overview

This library provides base classes and interfaces for managing UI state, handling user actions, and emitting side effects in a Compose Multiplatform project.

Key Components

• BaseViewModel: A base ViewModel class that manages state and handles user actions.
• BaseViewModelWithEffect: Extends BaseViewModel to also manage UI side effects.
• UiState: A marker interface for defining UI states.
• UiAction: A marker interface for user actions.
• UiEffect: A marker interface for UI side effects.

Installation

To use MVVMate in your project, add the following to your build.gradle.kts:

For Kotlin Multiplatform Projects:

kotlin {
    sourceSets {
        val commonMain by getting {
            dependencies {
                implementation("com.helloanwar.mvvmate.core:1.0.0")
            }
        }
    }
}

For Android Projects:

dependencies {
    implementation("com.helloanwar.mvvmate.core:1.0.0")
}

Usage

Here's a simple example of how you can use MVVMate in your Compose Multiplatform project:

// Define your UI State
data class MyUiState(val message: String = "") : UiState

// Define your User Actions
sealed class MyUiAction : UiAction {
    object ShowMessage : MyUiAction()
}

// Define your ViewModel
class MyViewModel : BaseViewModel<MyUiState, MyUiAction>(MyUiState()) {
    override suspend fun onAction(action: MyUiAction) {
        when (action) {
            MyUiAction.ShowMessage -> updateState { copy(message = "Hello, World!") }
        }
    }
}

// Use the ViewModel in your Composable function
@Composable
fun MyScreen(viewModel: MyViewModel) {
    val state by viewModel.state.collectAsState()

    Text(text = state.message)
    Button(onClick = { viewModel.handleAction(MyUiAction.ShowMessage) }) {
        Text("Show Message")
    }
}
