Creating a new Component
Components are the reusable building blocks of your application. They are the most basic UI elements and can be used to build more complex components.
Jetpack Compose
kotlin
@Composable
fun MyComponent(
    displayString: String
) {
    Text(displayString)
}
Vue.js
javascript
<template>
  <div>{{ displayString }}</div>
</template>

<script setup>
import { defineProps } from 'vue';

const props = defineProps({
  displayString: String
});
</script>
Conditional Rendering
Conditional rendering is a technique used to display different UI components or content based on certain conditions, such as the value of a variable or the outcome of a boolean expression.
Jetpack Compose
kotlin
@Composable
fun ConditionalComponent(condition: Boolean) {
    if (condition) {
        Text("Condition is true")
    } else {
        Text("Condition is false")
    }
}

// Usage
ConditionalComponent(condition = true)
Vue.js
javascript
<template>
  <p v-if="condition">Condition is true</p>
  <p v-else>Condition is false</p>
</template>

<script setup>
import { defineProps } from 'vue';

const props = defineProps({
  condition: Boolean
});
</script>
Prop/Parameter Drilling
Prop/Parameter drilling is a technique where data is passed through multiple layers of components in the component hierarchy, often from a parent component to a deeply nested child component, via props or parameters.
Jetpack Compose
kotlin
@Composable
fun Parent(data: String) {
    IntermediateComponent(data = data)
}

@Composable
fun IntermediateComponent(data: String) {
    ChildComponent(data = data)
}

@Composable
fun ChildComponent(data: String) {
    Text("Received data: $data")
}

// Usage
Parent(data = "Some data")
Vue.js
javascript
<template>
  <intermediate-component :data="data" />
</template>

<script setup>
import { defineProps } from 'vue';
import IntermediateComponent from './IntermediateComponent.vue';

const props = defineProps({
  data: String
});
</script>
Responding to events
Responding to events involves handling user interactions, such as button clicks or text input changes, and updating the component's state or triggering side effects accordingly.
Jetpack Compose
kotlin
@Composable
fun ClickableComponent() {
    var clicked by remember { mutableStateOf(false) }

    Button(onClick = { clicked = true }) {
        Text(if (clicked) "Button clicked" else "Click me")
    }
}
Vue.js
javascript
<template>
  <button @click="setClicked">
    {{ clicked ? "Button clicked" : "Click me" }}
  </button>
</template>

<script setup>
import { ref } from 'vue';

const clicked = ref(false);

function setClicked() {
  clicked.value = true;
}
</script>
Handing user input
Handling user input involves capturing and processing user interactions with input fields, such as text fields, sliders, or checkboxes, and updating the component's state or triggering side effects based on the input.
Jetpack Compose
kotlin
@Composable
fun TextInputComponent() {
    var text by remember { mutableStateOf("") }

    TextField(
        value = text,
        onValueChange = { newText -> text = newText },
        label = { Text("Enter text") }
    )
}
Vue.js
javascript
<template>
  <input
    type="text"
    v-model="text"
    placeholder="Enter text"
  />
</template>

<script setup>
import { ref } from 'vue';

const text = ref('');
</script>
Previewing a Component
Creating a preview of a component involves displaying a visual representation of the component in the development environment to help with the design and layout process.
Jetpack Compose
kotlin
@Composable
fun ExampleComponent() {
    Text("Hello, World!")
}

@Preview(showBackground = true)
@Composable
fun ExampleComponentPreview() {
    ExampleComponent()
}

Additionally, you can also use Showkase, an open source library by Airbnb that allows you to view themes preview functions in an auto-generated component browser that can be viewed on an Android device.

Vue.js

Vue.js doesn't have a built-in preview feature. However, you can use a tool like Storybook to create previews for your components in a separate development environment.

Lists & Looping
Lists and looping involve rendering a dynamic number of components based on the length of a list or array, iterating over the list, and generating a UI component for each item.
Jetpack Compose
kotlin
@Composable
fun ListComponent(items: List<String>) {
    LazyColumn {
        items(items) { item ->
            Text(item)
        }
    }
}

// Usage
val items = listOf("Item 1", "Item 2", "Item 3")
ListComponent(items = items)
Vue.js
javascript
<template>
  <ul>
    <li v-for="item in items" :key="item">
      {{ item }}
    </li>
  </ul>
</template>

<script setup>
import { defineProps } from 'vue';

const props = defineProps({
  items: Array
});
</script>

<!-- Usage -->
<list-component :items="['Item 1', 'Item 2', 'Item 3']"></list-component>
List item keys
List Item Keys are unique identifiers assigned to each list item in declarative UI frameworks to help manage and update list elements efficiently. Using List Item Keys enables the framework to optimize the rendering process, minimizing unnecessary updates and improving overall performance.
Jetpack Compose
kotlin
data class Person(val name: String, val age: Int, val id: String)

@Composable
fun ItemKeysExample(items: List<Person>) {
    LazyColumn {
        items(items, key = { person -> person.id }) { person ->
            Text("Name: ${person.name}, Age: ${person.age}")
        }
    }
}
Vue.js
javascript
<template>
  <ul>
    <li v-for="person in items" :key="person.id">
      Name: {{ person.name }}, Age: {{ person.age }}
    </li>
  </ul>
</template>

<script setup>
import { defineProps } from 'vue';

const props = defineProps({
  items: Array
});
</script>

<!-- Usage -->
<item-keys-example
  :items="[
    { name: 'John', age: 30, id: '1' },
    { name: 'Jane', age: 28, id: '2' },
    { name: 'Bob', age: 25, id: '3' }
  ]"
></item-keys-example>
Slot APIs
Slot APIs refer to a technique where components have customizable parts or 'slots' that can be filled with content when the component is being used. This allows for greater reusability and flexibility in composing user interfaces. The content that fills these slots can be other components or simple UI elements like text or images.
Jetpack Compose
kotlin
@Composable
fun Parent(
    header: @Composable () -> Unit,
    content: @Composable () -> Unit
) {
    Column {
        header()
        content()
    }
}

// Usage
Parent(
    header = { Text("Header") },
    content = { Child() }
)

@Composable
fun Child() {
    Text("Child Content")
}
Vue.js
javascript
// ParentComponent.vue
<template>
  <div>
    <slot name="header"></slot>
    <slot name="content"></slot>
  </div>
</template>

// ChildComponent.vue
<template>
  <p>Child Content</p>
</template>

// Usage
<parent-component>
  <template v-slot:header>
    <h1>Header</h1>
  </template>
  <template v-slot:content>
    <child />
  </template>
</parent-component>
Modifiers
Modifiers are used to adjust or configure the UI elements' appearance or behavior in a declarative UI framework.
Jetpack Compose
kotlin
@Composable
fun ModifiersExample() {
    Text(
        "Hello, World!",
        modifier = Modifier
            .padding(16.dp)
            .background(Color.Blue)
    )
}
Vue.js

Vue.js doesn't have a direct analog to modifiers in Jetpack Compose or SwiftUI. Instead, you can use inline styles or CSS classes.

javascript
<template>
  <div :style="style">Hello, World!</div>
</template>

<script setup>
import { reactive } from 'vue';

const style = reactive({
  padding: '16px',
  backgroundColor: 'blue',
  color: 'white'
});
</script>
State
State management refers to the process of handling and updating the internal state of components, often in response to user interactions or other events.
Jetpack Compose
kotlin
@Composable
fun Counter() {
    var count by remember { mutableStateOf(0) }

    Button(onClick = { count = count + 1 }) {
        Text("Count: $count")
    }
}
Vue.js
javascript
<template>
  <button @click="incrementCount">
    Count: {{ count }}
  </button>
</template>

<script setup>
import { ref } from 'vue';

const count = ref(0);

function incrementCount() {
  count.value++;
}
</script>
Scoped Data Propagation
Scoped Data Propagation is a technique that involves passing data across multiple levels of a component subtree without having to explicitly pass it through every intermediate component. It helps reduce the complexity of prop drilling and allows for a more efficient way of sharing data in a specific scope.
Jetpack Compose
kotlin
val CustomLocal = compositionLocalOf<String> { "Default data" }

@Composable
fun Parent(data: String) {
    CompositionLocalProvider(CustomLocal provides data) {
        Intermediate()
    }
}

@Composable
fun Intermediate() {
    Child()
}

@Composable
fun Child() {
    val data = CustomLocal.current
    Text("Received data: $data")
}

// Usage
Parent(data = "Some data")
Vue.js
javascript
<!-- ParentComponent.vue -->
<template>
  <intermediate />
</template>

<script setup>
import { provide, ref } from 'vue';
import Intermediate from './IntermediateComponent.vue';

const data = ref('Some data');
provide('dataKey', data);
</script>

<!-- IntermediateComponent.vue -->
<template>
  <child />
</template>

<script setup>
import Child from './ChildComponent.vue';
</script>

<!-- ChildComponent.vue -->
<template>
  <p>Received data: {{ data }}</p>
</template>

<script setup>
import { inject } from 'vue';

const data = inject('dataKey');
</script>


<!-- Usage -->
<parent-component data="Some data"></parent-component>
Side Effects
A side effect involves executing code that can have external consequences or perform operations that are not directly related to rendering the UI, such as making network requests or updating external data sources.
Jetpack Compose
kotlin
@Composable
fun SideEffectOnLoadComponent() {
    LaunchedEffect(Unit) {
        // Perform side effect, e.g. fetch data, update external data source
    }

    // Other UI components
    Text("Hello, World!")
}
Vue.js
javascript
<template>
  <div></div>
</template>

<script setup>
import { onMounted } from 'vue';

onMounted(() => {
  // Perform side effect here
});
</script>

Web + Mobile Strategy: A common approach is to use Vue.js for your web application, while using Jetpack Compose for mobile apps. You can share business logic and API calls between them, but the UI layer would be implemented separately for each platform.

How does Jetpack Compose compare to traditional Android XML layouts?

Jetpack Compose represents a significant shift from traditional Android XML layouts:

Traditional XML Layouts

  • Declarative XML with imperative Java/Kotlin manipulation
  • View hierarchy with expensive findViewById() calls
  • Complex layouts like ConstraintLayout for performance
  • Separate files for layouts, styles, and logic
  • Many boilerplate adapters and view holders
  • Slow layout inflation process

Jetpack Compose

  • Fully declarative Kotlin code for UI
  • No view hierarchy or findViewById()
  • Layout composables handle optimization automatically
  • UI, styling, and logic in one place
  • Simple list creation with LazyColumn/LazyRow
  • No layout inflation, faster rendering

Compose brings significant advantages in:

  • Code reduction: Much less boilerplate code compared to XML
  • State management: Built-in state handling with react-like patterns
  • Preview: @Preview annotation for seeing UI changes without deploying
  • Animation: Simplified animations with type-safe builders
  • Testing: Better testability without complex UI testing setups

Migration can be gradual - Compose can be adopted incrementally within existing XML-based apps through the ComposeView component.
