How do i refresh/rerender an Astro component when data changes?
问题
我有这个简单的组件。当我知道API数据已更改时，如何刷新/重新渲染它？
示例：当我单击仪表板项目之一时，将生成一个包含表单的对话框。当该表单被提交时，API数据将更改，我需要刷新组件。
或者我是否需要使用VUE、React或另一个框架来完成这个任务？
---
import Layout from "../layouts/Layout.astro";
import BrokerDashboardItem from "../components/BrokerDashboardItem.astro";
const response = await fetch(
"https://api/"
);
const data = await response.json();
---
<Layout title="Broker Dashboard">
<div>
{
data.map((item) => (
<BrokerDashboardItem
priority="{item.priority}"
date="{item.date}"
clientName="{item.clientName}"
statusText="{item.statusText}"
statusProgress="{item.statusProgress}"
title="{item.title}"
/>
))
}
</div>
<style></style>
</Layout>
请注意，刷新组件的方式取决于您使用的框架或库。如果您正在使用Vue或React等前端框架，通常会有特定的机制来处理组件的刷新和重新渲染。如果您只是使用原生JavaScript和HTML，您可以考虑手动更新组件的数据或状态以触发重新渲染。

I have this simple component. How do i refresh/rerender it when i know the api data has changed?
Example: When i click one of the dashboard items i will spawn a dialog which contains a form. When that form is submitted the api data will change and i need to refresh the component.
Or do i need VUE, React or another framework to do this?

Astro组件的渲染逻辑仅存在于服务器上，因此要在客户端上重新渲染，您需要选择以下之一：
-
使用像Preact、React、Vue、Solid、Svelte等支持在客户端上重新渲染的框架。
-
在
<script>标签中编写描述如何更新组件的交互性，例如使用自定义元素。
您选择哪种方式主要取决于个人偏好和项目要求。如果您只有少数几个这种更新行为的实例，我可能会选择编写一个自定义元素来处理这些事情。但如果项目需要大量互动，通常使用UI框架将有助于更轻松地构建和维护。
英文:
The Astro component rendering logic is only present on the server, so to re-render on the client you need to choose one of the following
-
Use a framework like Preact, React, Vue, Solid, Svelte etc., which support re-rendering on the client.
-
Write the interactivity describing how to update the component in a
<script>tag, for example with a custom element.
Which you choose is mostly up to personal preference and project requirements. If you have only a few instances of this kind of updating behaviour, I might choose to write a custom element to handle things. But if the project is heavily interactive, often a UI framework will help make that easier to build and maintain.
