VuePress implements a content distribution API for Markdown. With this feature, you can split your document into multiple fragments to facilitate flexible composition in the layout component.
Why do I need Markdown Slot?
First, let's review the relationship between layout components and markdown files:
Markdown files are providers of metadata (Page content, Configuration, etc.), while layout components consume them. We can use
frontmatter to define some metadata for common data types, but
frontmatter is hard to do something about markdown / HTML, a complex metadata that involves differences before and after compilation.
Markdown Slot is to solve this kind of problem.
You can define a named markdown slot through the following markdown syntax:
::: slot name :::
Content component to use the slot in the layout component:
Here we are using
slot-key instead of
slot, because in Vue,
slot is a reserved prop name.
Default Slot Content
By default, the slot-free part of a markdown file becomes the default content of a markdown slot, which you can access directly using the
Suppose your layout component is as follows:
<template> <div class="container"> <header> <Content slot-key="header"/> </header> <main> <Content/> </main> <footer> <Content slot-key="footer"/> </footer> </div> </template>
If the markdown content of a page is like this:
::: slot header # Here might be a page title ::: - A Paragraph - Another Paragraph ::: slot footer Here's some contact info :::
Then the rendered HTML of this page will be:
<div class="container"> <header> <div class="content header"> <h1>Here might be a page title</h1> </div> </header> <main> <div class="content default"> <ul> <li>A Paragraph</li> <li>Another Paragraph</li> </ul> </div> </main> <footer> <div class="content footer"> <p>Here's some contact info</p> </div> </footer> </div>
- Unlike the slot mechanism provided by Vue itself, each content distribution is wrapped in a
divwhose class is
contentwith the name of the slot.
- Please ensure the uniqueness of the slot defined.
