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

Love when all my random browsings meld well together!
DEV is using this service: HTML/CSS to Image API - basically you pass the markup and the styling and they give you back an image.
It's built by a DEV member, @mscccc :
