Vue3 + rspack 003: The Art of Componentization (Composition API) and Common Problem Solving Ideas

In Vue 3, the Composition API provides us with a new way to reuse components and logic. This not only brings better organization structure to our code, but also allows us to handle complex component logic more flexibly. Let’s explore it below.

Create and use components

Components are the fundamental building blocks of Vue applications. In the Composition API, we use the setupfunction to define the reactive state and behavior of components.

Example: Simple counter component

<template>
  <button @click="increment">{{ count }}</button>
</template><script>
import { ref } from 'vue';export default {
  setup() {
    const count = ref(0);
    function increment() {
      count.value++;
    }    return { count, increment };
  }
};
</script>

Practical difficulties and solutions

Difficulties : When using the Composition API, developers may experience fragmented state logic, making components difficult to maintain.

Solution : Encapsulate the relevant logic into a function and then call this function in the setup. This can improve the readability and…
