Best Practices

• Use createContentLoader for archives and indexes over manual data loading — automatically handles caching and minimizes client-side JSON weight source

import { createContentLoader } from 'vitepress'
export default createContentLoader('posts/*.md', { excerpt: true })

• Wrap browser-only components with defineClientComponent — prevents SSR/SSG build failures when libraries access window or document on import source

<script setup>
import { defineClientComponent } from 'vitepress'
const ClientOnlyComp = defineClientComponent(() => import('./BrowserComponent.vue'))
</script>

• Prefer relative URLs for images and assets in Markdown — enables Vite's hashing pipeline and automatic base64 inlining for small files source

• Use the withBase() helper for dynamic paths in theme components — ensures assets resolve correctly regardless of the site's deployment base URL source

• Enable cleanUrls: true only when server-side support is confirmed — prevents broken direct links on platforms that do not automatically map /foo to /foo.html source

• Target rewritten paths for relative links when using rewrites — links must resolve against the final URL structure, not the source directory structure source

• Pass large Markdown or HTML blocks via the content property in dynamic route loaders — prevents bloating the client-side JavaScript payload with serialized params source

// [pkg].paths.js
export default {
  async paths() {
    return [{ params: { id: '1' }, content: '## Large Content' }]
  }
}

• Use <script client> for minimal interactivity in MPA mode — standard <script setup> in MPA mode is used for server-side templating only and lacks reactivity source

• Programmatically exclude pages from search via the _render hook — allows complex filtering logic based on file path or frontmatter during the indexing phase source

// .vitepress/config.ts
themeConfig: {
  search: {
    provider: 'local',
    options: {
      _render(src, env, md) {
        if (env.frontmatter?.search === false) return ''
        return md.render(src, env)
      }
    }
  }
}

• Employ defineConfigWithTheme<DefaultTheme.Config> for site configuration — provides full TypeScript inference and validation for both core and default theme settings source
