标签页面

以下代码片段演示了如何创建 /tags/:id 页面。

app/tags/[tag]/page.jsx


import { PostCard } from 'nextra-theme-blog'
import { getPosts, getTags } from '../../posts/get-posts'
 
export async function generateMetadata(props) {
  const params = await props.params
  return {
    title: `Posts Tagged with “${decodeURIComponent(params.tag)}”`
  }
}
 
export async function generateStaticParams() {
  const allTags = await getTags()
  return [...new Set(allTags)].map(tag => ({ tag }))
}
 
export default async function TagPage(props) {
  const params = await props.params
  const { title } = await generateMetadata({ params })
  const posts = await getPosts()
  return (
    <>
      <h1>{title}</h1>
      {posts
        .filter(post =>
          post.frontMatter.tags.includes(decodeURIComponent(params.tag))
        )
        .map(post => (
          <PostCard key={post.route} post={post} />
        ))}
    </>
  )
}
