In my company we need to send Discord or WhatsApp messages (eg. alert about something, etc), which cannot unfortunately embed HTML widgets, but I wanted to make it possible to show a "card-like" component with colors, graphs, etc

I coded a small backend which lets you mount a VueJS widget (it would work with React too), pass it props from the POST/GET parameters, render it to PNG and send it back
