ComposeReact

Introduction 🙋‍♂️ 🙋‍

This is just for fun project where i tried to figure out, how Jetpack Compose could be used with API similar to React. The code is working so far, but i'm not really planning to go further with this approach.

Usage

You need at least Compose 0.1.0-dev12

Add dependency

repositories {
    mavenCentral()
}

dependencies {
   implementation "de.jensklingenberg:composereact:0.1-0.12"
}

Create a RComponent

1. Create a class that extends de.jensklingenberg.composereact.RComponent

class FirstComponent : RComponent<RProps, RState>() {

2. Implement the render() function and add the @Composable annotation

@Composable
override fun render() {
//Add your Composables and RComponents here
}

Use a RComponent

To use your RComponent inside other Composables, create an object and call the start()-function

@Composable
override fun render() {
 Column{
   MyOtherComponent().start()
 }
}

Inside the setContent{} of your Activity/View, you can also use runApp()

setContent {
    runApp ( FirstComponent() )
}

Define a State

Create a data class that extends RState

data class MyState(var name: String): RState

Add the class to your Component

class FirstComponent : RComponent<RProps, MyState>() {

Override the initState() and initialize your state

override fun initState(): MyState = MyState("Foo")

You can then use state.value to get your state and set your state with setState()-function like this:

setState {myState->
myState.copy(name = "Bar")
}

Define Props

Create a data class that extends RProps

data class MyProps(var name: String): RProps

Add the class to your Component

class FirstComponent(props: MyProps) : RComponent<MyProps, MyState>() {

Override the initState() and initialize your state

 override fun initState(props: MyProps): MyState { 
        return MyState(text = props.text) }

Lifecycle

You can override the following lifecycle methods:

• componentWillMount()

Will be called before the RComponent/Composable is drawn to screen.

• componentDidMount()

Will be called when the RComponent/Composable is drawn to screen.

• componentWillUnmount() Will be called when the RComponent/Composable is going to be disposed
