Vue 预渲染闪烁
Vue prerender flickering
我现在有以下解决方案:
<template>
<section id="prod-main">
<prod-preview v-for="prod in products" :id="prod.id" :key="prod.id"/>
</section>
</template>
export default {
...
computed: {
products: function () {
return this.$store.getters['products/getPreview']
}
}
...
}
Vuex 商店将在我的后端延迟一段时间后接收信息。所以一开始它会是空的。现在我想使用 vue spa prerender,这里我看到闪烁。
据我了解,它的工作方式如下:
1. 浏览器加载 HTML 产品
2. 执行js把products替换成nothing,因为store是空的
3. 延迟一段时间后再次显示后端信息。
我该如何解决?我应该为索引保留预渲染,我不能对后端回复进行硬编码。
我不知道我是否理解你的问题,但你是否尝试添加一个 v-if
以避免闪烁:
<template>
<section id="prod-main">
<prod-preview
v-if="products.length > 0"
v-for="prod in products"
:id="prod.id"
:key="prod.id"/>
</section>
</template>
您可以使用设置 captureAfterTime
等待异步调用完成,然后再保存页面的 html。
其他设置可用:
// NOTE: Unless you are relying on asynchronously rendered content,
// such as after an Ajax request, none of these options should be
// necessary. All synchronous scripts are already executed before
// capturing the page content.
// Wait until a specific event is fired on the document.
captureAfterDocumentEvent: 'custom-post-render-event',
// This is how you would trigger this example event:
// document.dispatchEvent(new Event('custom-post-render-event'))
// Wait until a specific element is detected with
// document.querySelector.
captureAfterElementExists: '#content',
// Wait until a number of milliseconds has passed after scripts
// have been executed. It's important to note that this may
// produce unreliable results when relying on network
// communication or other operations with highly variable timing.
captureAfterTime: 5000,
另一个问题可能与预渲染的 HTMl 如何水合有关,我已经在 github 上打开了一个问题,但他们仍然没有解决它(并且不愿意? )

解决方案是在预渲染的html中添加data-server-rendered="true"
到你的vuejs父节点,像这样:
<div id="root" data-server-rendered="true">...
您可以使用选项 postProcessHtml
来执行此操作。
