Vue

Vue is introducing support for declarative UI syntax, bringing it closer to mobile development patterns seen in Kotlin and Swift. This new approach moves away from traditional HTML templates, offering a more modern, type-safe way to build user interfaces. The Evolution Traditional Vue templates use HTML: <template> <div class="container"> <h1>{{ title }}</h1> <button @click="handleClick">Click me</button> </div> </template> The new declarative syntax is more similar to SwiftUI or Jetpack Compose: <script setup> import { View, Text, Button } from "vue-declarative"; const title = ref("Hello World"); function handleClick() { console.log("Clicked!"); } </script> <template> <View class="container"> <Text>{{ title }}</Text> <Button onPress="{handleClick}">Click me</Button> </View> </template> Key Benefits 1. Type Safety The declarative syntax provides better TypeScript support: ...

Vue 3’s Composition API provides better code organization. Here’s how to use it effectively. Setup import { ref, computed, watch } from 'vue'; export default { setup() { const count = ref(0); const doubled = computed(() => count.value * 2); watch(count, (newVal) => { console.log('Count changed:', newVal); }); return { count, doubled }; } } Script Setup <script setup> import { ref, computed } from 'vue'; const count = ref(0); const doubled = computed(() => count.value * 2); function increment() { count.value++; } </script> Composables // useCounter.js import { ref } from 'vue'; export function useCounter(initialValue = 0) { const count = ref(initialValue); const increment = () => count.value++; const decrement = () => count.value--; return { count, increment, decrement }; } Best Practices Use composables for reusability Keep setup functions focused Use script setup syntax Organize by feature Extract complex logic Conclusion Vue 3 Composition API enables better code organization! 🎯
