A Nuxt module for table of contents (TOC) component in your Nuxt Content projects.

  • 🔗 Section Links: Navigate seamlessly within your content.

Quick Start 🔧

  1. Install the module to your Nuxt application:
npx nuxi module add nuxt-toc
  1. Add <TableOfContents /> at where you need the TOC.
<template>
    <ContentDoc />
    <TableOfContents />
</template>

You can also pass in TOC yourself to prevent duplicate fetching.

<template>
    <ContentRenderer :value="data" />
    <TableOfContents :toc="data.body.toc" />
</template>

<script setup>
const route = useRoute()

const { data } = await useAsyncData('home', () => queryContent(route.path).findOne())
</script>
