TODOvue Article (TvArticle)

A Vue 3 component to display rich article content with polished typography, optional cover image, metadata (date, reading time, tags), and copyable heading anchors. Works in SPA and SSR (e.g., Nuxt 4) and injects styles automatically.

Features

• Polished prose typography for long content (paragraphs, lists, tables, quotes, code, images, etc.).
• H2–H4 headings get a “copy link” anchor button with localized feedback text.
• Optional metadata: date (rendered with relative-time component), reading time (estimated or forced), and colored tags.
• Cover image with loading, decoding, fetchpriority and aspect ratio control.
• Configurable layout: centered container and prose width (sm, base, md, lg, full).
• Slots for header/before/after/footer; default slot used when content.body is not provided.
• External links safety: open in a new tab with rel="noopener noreferrer" automatically.
• CSS auto-injected via JS: no manual CSS import required.

Internal deps: uses @todovue/tv-label (tags) and @todovue/tv-relative-time (date). You only need to install @todovue/tv-article.

Installation

Using npm:

npm install @todovue/tv-article

Using yarn:

yarn add @todovue/tv-article

Using pnpm:

pnpm add @todovue/tv-article

Peer: Vue ^3.

Quick Start (SPA)

Important: You must explicitly import the stylesheet in your application.

Global registration (main.js / main.ts):

import { createApp } from 'vue'
import App from './App.vue'

import { TvArticle } from '@todovue/tv-article'
import '@todovue/tv-article/style.css' // import styles
import '@todovue/tv-label/style.css' // tv-article depends on tv-label

const app = createApp(App)
app.component('TvArticle', TvArticle)
app.mount('#app')

Local import inside a component:

<script setup>
import { TvArticle } from '@todovue/tv-article'
import '@todovue/tv-article/style.css'

const article = {
  title: 'Introduction to Vue 3',
  description: 'Key concepts and the Composition API',
  date: '2025-10-15',
  readingTime: 8, // optional; if missing, it is estimated from body
  tags: [ 'Vue', { tag: 'JavaScript', color: '#F7DF1E' } ],
  body: `
    <h2 id="what-is-vue">What is Vue?</h2>
    <p>Provide safe HTML to v-html…</p>
  `
}
</script>

<template>
  <TvArticle :content="article" lang="en"></TvArticle>
</template>

Nuxt 4 / SSR Usage

Create a plugin file: plugins/tv-article.client.ts (or without suffix; SSR-safe since DOM access happens in onMounted):

// nuxt.config.ts
export default defineNuxtConfig({
  modules: [
    '@todovue/tv-article/nuxt'
  ]
})

Use anywhere:

<TvArticle :content="{ title: 'Post', body: '<p>Hello</p>' }"></TvArticle>

Component Registration Options

Approach	When to use
Global via app.use(TvArticle)	Many usages across app / design system install
Local named import { TvArticle }	Isolated or code-split contexts
Direct default import import TvArticle	Single usage or manual registration

Props

All content is expected to be safe HTML for content.body (it is rendered via v-html).

• Prop: content (Object) [default: { title: '', body: '' }]

  • title: string
  • description: string
  • date: string | Date (rendered relatively via @todovue/tv-relative-time)
  • readingTime: number (minutes; if omitted, estimated at ~200 wpm)
  • tags: Array<string | { tag: string, color?: string }>
  • cover: string (image URL)
  • coverAlt: string
  • coverCaption: string
  • body: string (HTML)

• Prop: ui (Object) [defaults below]

  • showTitle: boolean (true)
  • showMeta: boolean (true)
  • showCover: boolean (true)
  • center: boolean (true)
  • proseSize: 'sm' | 'base' | 'md' | 'lg' | 'full' ('full')
  • coverLoading: 'lazy' | 'eager' ('lazy')
  • coverDecoding: 'async' | 'sync' ('async')
  • coverFetchPriority: 'auto' | 'high' | 'low' ('auto')
  • coverAspect: string | null (e.g., '16 / 9')

• Prop: lang (String) [default: 'en']

  • Affects reading time text and anchor button labels ('en', 'es', 'fr', 'pt').

Events

Event (kebab)	Payload	Description
anchor-copied	string (anchorId)	Emitted when a heading link is copied

Usage:

<TvArticle @anchor-copied="onCopied"></TvArticle>

function onCopied(id) {
  console.log('Anchor copied:', id)
}

Slots

• header: Replace the entire header (title, description, meta, cover). If not provided, TvArticle renders the header based on ui and content.
• before: Content before the article body.
• after: Content after the article body.
• footer: Footer area (author, share, etc.).
• default: When content.body is missing, the default slot is rendered inside the prose container.

Customization (Styles / UI)

• Styles: the package injects CSS automatically when you import the component (no extra CSS import needed).
• Layout: control width with ui.proseSize and centering with ui.center.
• Cover: adjust ui.coverAspect, coverLoading, coverDecoding, and coverFetchPriority.
• Tags: content.tags accepts strings or { tag, color } objects.
• For deeper theming, override the .tv-article* classes in your app.

Accessibility

• aria-labelledby is applied to <article> when a title is present.
• Anchor button on H2–H4 with localized aria-label/title and copied feedback.
• External links are marked with target="_blank" and rel="noopener noreferrer" for safety.

SSR Notes

• No DOM access during setup; enhancements (anchors/links) happen in onMounted, making it SSR-safe.
• Styles are injected on the client via JS; no need to import CSS manually.

Examples

Basic:

<TvArticle :content="{
  title: 'Introduction to Vue 3',
  date: '2025-10-15',
  readingTime: 8,
  tags: ['Vue', 'JavaScript'],
  body: '<h2 id=&quot;what-is&quot;>What is it?</h2><p>…</p>'
}" lang="en"></TvArticle>

With cover and aspect ratio:

<TvArticle
  :content="{
    title: 'Nuxt Content Guide',
    description: 'Build blogs and docs',
    date: '2025-10-20',
    readingTime: 12,
    tags: ['Nuxt', 'Markdown'],
    cover: 'https://images.unsplash.com/photo-1499750310107-5fef28a66643?w=1200&h=675&fit=crop',
    coverAlt: 'Laptop with code',
    coverCaption: 'Content with cover image',
    body: '<h2 id=&quot;intro&quot;>Introduction</h2><p>…</p>'
  }"
  :ui="{ coverAspect: '16 / 9', center: true }"
></TvArticle>

Custom UI + footer slot:

<TvArticle
  :content="{ title: 'Typography', body: '<h2 id=&quot;h2&quot;>H2</h2><p>…</p>' }"
  :ui="{ proseSize: 'lg', center: true }"
  @anchor-copied="id => console.log(id)"
>
  <template #footer>
    <hr />
    <small>Author: TvArticle Team</small>
  </template>
</TvArticle>

Minimal:

<TvArticle :content="{ title: 'Minimal', body: '<p>Only content</p>' }" :ui="{ showMeta: false, showCover: false, proseSize: 'base' }"></TvArticle>

Development

git clone https://github.com/TODOvue/tv-article.git
cd tv-article
npm install
npm run dev      # demo playground with Vite
npm run build    # library build (ESM/CJS + d.ts)
npm run build:demo  # demo site build (dist-demo)

The library marks vue as external and generates dist/tv-article.es.js, dist/tv-article.cjs.js, dist/tv-article.css, and type definitions.

Notes

• content.body is rendered with v-html: provide sanitized HTML if it comes from Markdown or external sources.
• Reading time falls back to an estimation of ~200 wpm when readingTime is not provided.
• Supported internal locales for UI text: en, es, fr, pt.
