A VuePress plugin to dehydrate generated HTML files.
npm install -g vuepress-plugin-dehydrate
# OR
yarn global add vuepress-plugin-dehydratenpm install vuepress-plugin-dehydrate
# OR
yarn add vuepress-plugin-dehydratemodule.exports = {
plugins: [
// workaround SSR mismatch
'dehydrate',
]
}or
module.exports = {
plugins: {
dehydrate: {
// disable SSR
noSSR: '404.html',
// remove scripts
noScript: [
// support glob patterns
'foo/*.html',
'**/static.html',
],
},
}
}VuePress will try to redirect unknown request /foo to /foo.html and /foo/. Other scenarios include redirecting / to /zh/ or /en/ based on navigator language.
Although Vuepress functions properly under most circumstances, if the page redirects before rendering, the pre-rendered parts will be structured differently from the target page of redirection, leading to a problem called SSR mismatch.
You request /foo in the browser, but the server can't find a direct match (without certain config), so a NotFound page /404.html will be returned. The beforeEach hook registered in handleRedirectForCleanUrls will redirect the router to /foo.html. Note that the DOM remains unchanged but the VDOM is replaced with /foo.html's. Normally, /404.html is a plain page without navbar and sidebar, but the new VDOM is a document page with such components. The DOM fails to match the VDOM, causing rendering error and the view will not be updated. This is an SSR Mismatch and its consequence.
Reference:
Sometimes we want to output a HTML page without all the fancy preload, prefetch and hydration script/styles. We can just use Vue / markdown files as a way to organize the static website structure. We can do CSS by setting a <link> that points to the CSS in the <head>. We don't need JS at runtime.
Reference:
It may be amazing, but the solutions to these two problems are similar. VuePress uses ssrTemplate as a template for SSR rendering. All we have to do is delete part of them. For the first problem, since all redirections where SSR mismatches occur take place on the 404 page, we only need to disable the SSR for that page. Since 404 pages are usually simple and not so necessary to be SEO friendly, this solution is reasonable. On the contrary, in the second case, we merely need to remove the the scripts for "hydration" rather than delete SSR pre-rendered HTML. This plugin provides both of these capabilities, allowing us to control every page effectively.
A normally generated HTML file will be like this:
<!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width,initial-scale=1">
<title>VuePress</title>
<meta name="description" content="">
<link rel="preload" href="/assets/css/0.styles.53e4595a.css" as="style"><link rel="preload" href="/assets/js/app.3fe70f2e.js" as="script"><link rel="preload" href="/assets/js/3.db027a4f.js" as="script"><link rel="preload" href="/assets/js/5.222ba868.js" as="script"><link rel="prefetch" href="/assets/js/2.418462f5.js"><link rel="prefetch" href="/assets/js/4.f6ba1d08.js"><link rel="prefetch" href="/assets/js/6.d7ad24ac.js">
<link rel="stylesheet" href="/assets/css/0.styles.53e4595a.css">
</head>
<body>
<div id="app" data-server-rendered="true"><div class="content default"><p>readme</p></div><div class="global-ui"></div></div>

</body>
</html>When we use the noSSR mode, VuePress will generate such HTML:
<!DOCTYPE html>
<html lang="en-US">

<meta charset="utf-8">
