How does Hashnode give rich link image previews of articles with no cover images?
This is an article whose author did not provide a cover image but Hashnode is able to generate an image with the title and as a placeholder in rich link previews
My question is how do I do that.

That's a really good question. There are libraries to make images out of code, surely that's how they do it. Maybe using SSR they create the meta tags for the image and check if the image exists and if not, they create it.

Hey Wachira!
Sorry about the delay! We use imgix to transform our images. It also lets us write text on a background image and generate og images. You can find more details here: docs.imgix.com/apis/url/blending
