Use the Code snippet template for posts whose subject is the code itself, a hook, a helper, a config. It runs a full width editor window across the card with the snippet's title as the header, drawn code inside, and a filename, language chip, and brand around it, so the card reads as code at a glance.
This template is a metadata image route for the Next.js App Router. The file exports size, contentType, and alt values plus a default async function that returns an ImageResponse. When the snippet page is shared, satori converts the JSX into an SVG document, the runtime rasterizes that SVG into a 1200 by 630 PNG, and Next.js serves the result and wires the og:image and twitter:image tags into the page head automatically. The code is drawn from bars rather than real text, so it stays legible at thumbnail size where actual source would turn to noise.
Install with the shadcn CLI using your Shadcn UI Blocks API key:
npx shadcn@latest add @shadcn-ui-blocks/og-image-code-snippet
The file lands at app/opengraph-image.tsx, which makes it the site wide share card. Move it into the snippet segment, for example app/snippets/[slug]/opengraph-image.tsx, when each snippet has its own page. You can also copy the code from this page straight into your project.
The card renders text with Inter, read from assets/fonts at your project root with node:fs so the font files never ship to the browser. Download the latin woff files for weights 400, 500, 600, and 700 from Fontsource and save them as assets/fonts/inter-latin-400-normal.woff and so on.
The content object holds brand, the filename shown in the window header, the title, the language chip, and the url. The codeLines array above the template draws the editor body as indent, width, and color tuples; reshape it to echo your snippet's shape, keeping the light accents sparse. To generate a card per snippet, accept params in the default export and pull the title, filename, and language from your content. Keep the title to one line at its 40px size.
satori supports a focused subset of CSS: flexbox layout only, flat colors, and an explicit display: flex on any element with multiple children. Keep those rules in mind if you rework the layout.
