vue3 代码拆分最佳实践?
老项目遗留了一些代码,VUE页面里面的代码太长了
想把TS代码拆分出来,请问最佳实践是什么样子的?
旧代码:
<template> <div class="table-tree-container">

</t-input>
<t-button block @click="onCleanActive" variant="dashed" size="small" class="mt-2">
<template #icon>
<i class="ri-close-circle-line mr-1"></i>
</template>

回答:
没仔细看你的代码,说说我的重构经验:
- 上下文不相关的函数,抽出来放到工具函数里。包括网络请求,都可以抽出来。
- 能够复用的功能,抽出来做成组件。组件的颗粒度以 方便理解 为准,细一点没关系。
- 样式我已经完全拥抱 TailwindCSS 了,所以几乎不存在
<style>
