步骤 1：创建博客布局

博客列表布局

步骤 2：创建文章模板

markdown

<!-- docs/blog/my-post.md -->
---
title: 我的第一篇博客
date: 2026-04-04
tags:
  - VitePress
  - 教程
readingTime: 5
excerpt: 这是一篇关于如何在 VitePress 中添加博客功能的教程。
---

# 我的第一篇博客

文章内容...

## 简介

...

## 正文

...

步骤 3：生成文章数据

创建脚本在构建时生成文章列表：

// scripts/generate-blog-data.ts
import fs from 'fs'
import path from 'path'
import matter from 'gray-matter'

interface Post {
  title: string
  path: string
  date: string
  tags: string[]
  excerpt: string
  readingTime: number
}

const posts: Post[] = []

function walk(dir: string) {
  const entries = fs.readdirSync(dir, { withFileTypes: true })
  
  for (const entry of entries) {
    const fullPath = path.join(dir, entry.name)
    
    if (entry.isDirectory()) {
      walk(fullPath)
    } else if (entry.name.endsWith('.md') && entry.name !== 'index.md') {
      const content = fs.readFileSync(fullPath, 'utf-8')
      const { data, content: body } = matter(content)
      
      if (!data.date) continue
      
      posts.push({
        title: data.title || entry.name,
        path: '/' + fullPath.replace('docs/', '').replace('.md', ''),
        date: data.date,
        tags: data.tags || [],
        excerpt: data.excerpt || body.slice(0, 200),
        readingTime: data.readingTime || Math.ceil(body.length / 300)
      })
    }
  }
}

walk('docs/blog')

// 按日期排序
posts.sort((a, b) => new Date(b.date).getTime() - new Date(a.date).getTime())

// 保存数据
fs.writeFileSync('docs/public/posts.json', JSON.stringify(posts, null, 2))

console.log(`✅ 生成 ${posts.length} 篇文章数据`)

步骤 4：创建博客首页

markdown

<!-- docs/blog/index.md -->
---
layout: ../../.vitepress/theme/layouts/BlogLayout.vue
title: 博客
subtitle: 分享技术心得与学习笔记
---

<script setup>
import { ref, onMounted } from 'vue'

const posts = ref([])

onMounted(async () => {
  const res = await fetch('/posts.json')
  posts.value = await res.json()
})
</script>

步骤 5：添加 RSS 支持

bash

npm install feed -D

// scripts/generate-rss.ts
import fs from 'fs'
import { Feed } from 'feed'

const feed = new Feed({
  title: '我的博客',
  description: '技术博客',
  id: 'https://your-domain.com',
  link: 'https://your-domain.com',
  language: 'zh-CN',
  copyright: 'Copyright 2026'
})

// 添加文章...
const posts = JSON.parse(fs.readFileSync('docs/public/posts.json', 'utf-8'))

posts.forEach(post => {
  feed.addItem({
    title: post.title,
    id: `https://your-domain.com${post.path}`,
    link: `https://your-domain.com${post.path}`,
    date: new Date(post.date),
    description: post.excerpt
  })
})

fs.writeFileSync('docs/public/rss.xml', feed.rss2())
