What it does
It is a small package for Astro, a website framework aimed at content-heavy sites. It generates one image per page when the site is built. You give it a background, a font, a logo and a set of colours, and it lays out the page title and description inside the standard 1200 by 630 frame. The pages it draws for are listed in one route file. Drawing is done by canvaskit-wasm, a drawing engine of several megabytes that is pulled in at build time only. Version 0.13.1 is the current npm release. It works with Astro and nothing else, and it draws from text you supply, so it cannot invent artwork or photographs.
Why it matters
Who it suits. Anybody publishing many pages on Astro who wants each shared link to look deliberate. A blog with eighty posts needs eighty preview images, and nobody draws eighty images by hand. Skip it entirely if the site is not built with Astro, because there is no way to use it.
Verdict. Worth twenty minutes on an Astro site, with one real reservation. The repository carries no licence file at all, and the npm package declares MIT. No licence means no permission by default, so the npm declaration is what anyone relying on it is relying on. The risk looks low, and the author is a well-known Astro maintainer, but the gap is worth knowing about before building something commercial on it. vercel/satori is the framework-independent way to do the same job.
- One small route file gives every page its own preview image.
- The images are drawn when the site is built, so nothing runs at request time and nothing costs money per view.
- The background, font, logo and colours are all configurable.
- No licence file in the repository. The npm package says MIT, and that mismatch is unresolved.
- Astro only. A site built on anything else cannot use it.
- It pulls in canvaskit-wasm, several megabytes of drawing engine, which makes builds slower. Visitors are not affected.
