OG Image


Release notes for Nuxt OG Image v3.


I'm excited to share the v3 of Nuxt OG Image is here, featuring a complete rewrite of the module to improve stability and developer experience.

Nuxt OG Image was and remains to be possible due to many experimental Nuxt / Nitro features as well as bespoke hacks:

  • Nuxt Islands
  • Nitro WASM support
  • Binary data with Unstorage and serving it with H3
  • Customising Nitro prerenderer

In rewriting the module, I wanted to opt-in to newer more stable ways of doing things, or send upstream PRs so I wouldn't need to rely on hacks.

I couldn't help myself improving the developer experience as I went.

๐Ÿš€ Features

โ›น๏ธ Play Time: New Playground

The playground has been redesigned with a focus on giving you more ways to preview and debug your templates. It introduces a number of tabs:

  • Design

The default design view, this is the similar to v2 playground. It gives you HMR of the template, the ability to change the options used to render the template.

New features include a social media previews (Twitter, Slack), changing the rendering (Chromium, Satori) and more.

  • Templates

See and preview all the OG templates available to you. You can select a template to switch to it.

This also introduces "Community Templates", which are templates designed by the community, accessible to you. There are 7 community templates so far and more to come. Feel free to submit your own!

  • Debug

See the raw input and output of the template. This is useful for debugging your templates. Will be expanded in the future.

  • Docs

๐Ÿ‡น Type Safety with defineOgImageComponent

In v2, you had to define your config using defineOgImage. This was okay but the API provided minimal type safety.

In v3, you can now define your config using defineOgImageComponent which provides type safety by reading the type definitions from the component you're using.

  // component name
  // component props
  { title: 'Hello!' },
  // image options
  { alt: 'A welcome message' }

๐Ÿƒ UnoCSS and Theming Support

Satori itself provides a subset of Tailwind CSS classes that you can use to style your templates. This is great but also limited.

With v3, the module now runs UnoCSS's preset-wind, loaded with your Tailwind / UnoCSS theme config, before Satori.

export default defineConfig({
  theme: {
    fontSize: {
      'mega-big': '100px',
    colors: {
      base: colors.white,
      primary: colors.green,

UnoCSS will convert any classes you use into inlined CSS for the style attribute. While this won't provide complete compatibility with Tailwind, it gives you access to a lot more classes than Satori alone.

  <div class="w-full h-full flex items-center justify-center bg-primary-500/50 text-base">
    <h1 class="text-mega-big">
      Custom Theme Classes!

๐Ÿ˜ More Emojis

In v2 we were limited to only twemoji emojis (Twitter Emojis).

In v3 we switch to using the Iconify API which gives us access to the following emoji families: twemoji, noto, fluent-emoji, fluent-emoji-flat, fluent-emoji-high-contrast, noto-v1, emojione, emojione-monotone, emojione-v1, streamline-emojis, openmoji

The default emoji family has been switched to noto, providing a more complete set of emojis and looks better generally.

๐Ÿ–ผ๏ธ JPEG OG Images

PNGs are great for most use cases, but they come at the cost of a larger file size.

For Chromium based rendering, jpeg images will now be rendered by default.

For Satori, you can now opt-in by adding a sharp dependency and switching the extension to jpeg.

See the JPEGs guide for more information.

๐Ÿ“ Nuxt Content integration

Using a component or composable with within your markdown content is a bit awkward.

With v3 the module now supports the ogImage frontmatter key that can be used to configure your OG Image. This will only work when you're using Document Driven mode, or you have set a path.

path: /blog/3-months-of-europe
  component: BlogOgImage
    image: /blog/3-months-of-europe.png
    readingMins: 5

๐Ÿ”„ OG Image Route Rule

In some cases, you'll want to apply OG Image settings for a subset of pages. With the new route rule support, you can now handle this even easier.

This lets you provide a ogImage key that will be either used or merged into the existing OG Image options.

For example, this documentation website uses it to set the icon depending on your path.

export default defineNuxtConfig({
  routeRules: {
    '/og-image/**': {
      ogImage: {
        props: { icon: 'carbon:image-search' }

Improved css-inline Compatibility

Whenever you add a template has a <style> block, we need to use the css-inline dependency to make sure the styles get applied correctly.

This dependency previously only had compatibility for Node based environments. With work the library has done to add full WASM support, we can now run this in all environments (Cloudflare support is still pending).

    <h1 class="title" />

<style scoped>
// just works in all environments now
.title {
  color: red;

โœจ Improvements

New OG Image URL

The old pattern for OG images was /<path>/__og_image__/og.png, this has been changed to /__og-image__/image/<path>/og.<extension>.

With this change, the route is no longer added as a middleware, meaning you can hook into the route yourself.

It also means it's easier to target using route rules if you want to make adjustments.

New OG Image Size

In v2 we render OG Images at 1200x630 (1:19), this was the recommended resolution from Facebook.

For better compatibility with other Social platforms, we now use 1200x600 (1:2). This particular will render OG Images better on WhatsApp.

Per-Template Custom Fonts

Sometimes you'll be rendering a custom template that you want to use a custom font with, without having to load that font for all templates.

Now you can using fonts prop on the defineOgImage component.

  fonts: [

See the Custom Fonts guide for more details.

Updated Default Template

The default template is now called NuxtSeo. It now uses a more modern design, with a focus on readability.

It introduces a number of new props:

  • colorMode - light, dark

Changes from a light or dark background / text color. Integrates with @nuxtjs/color-mode, selecting your default color mode.

  • theme - #${string}

Change the hex color of the flare and the Nuxt SEO logo.

v3 light mode

Learn more on the NuxtSeo Template docs.

Stale-While-Revalidate Caching

When generating images at runtime, it's important that we cache them to reduce the load on your server.

While caching for v2 worked, it was a bit of a mess with many configuration options.

In v3, the caching has been simplified to a single prop called cacheMaxAgeSeconds that by default, is set to 259200 (72 hours).

While not recommended, you can disable the caching by providing cacheMaxAgeSeconds: 0. You should instead opt for a lower cache time cacheMaxAgeSeconds: 300 (5 minutes).

Additionally, Stale-While-Revalidate is now enabled by default, it also will correctly respond with 304 Not Modified codes, avoiding extra bills for your hosting.

Prerendering Improvements

With the introduction of the Nitro prerender:config hook (#1519), the module can now natively handle the prerendering of screenshots, allowing you to make use of concurrency.

This also means that if you're generating your app with nuxi generate, that the module will no longer bundle any Satori or Playwright dependencies.

Pre-existing OG Images

In some cases, you'll have a page that you already have a designed OG Image for that you want to use instead of the dynamically generated one.

In those cases you can now provide a url to defineOgImage and all the tags will be set up properly for you.

defineOgImage({ url: 'https://example.com/og.png' })

Simple HTML OG Images

If you want to simplify your integration, you can provide raw HTML to the defineOgImage composable instead of creating a new component.

  html: `<div class="w-full h-full text-6xl flex justify-end items-end bg-blue-500 text-white">
    <div class="mb-10 underline mr-10">hello world</div>

Opt-ing out of OG Images

On some pages, you may want to disable the OG Image generation, you can now do this with by providing a false value for the options.

// removes all of the og image tags
