When i post a url into Discord or WhatsApp this pops up. What is it called? I have been searched on how to do this can someone tell me (if possible in express.js or anything that uses node)

CodePudding user response：

The tag is called Meta Tag

You can specify different meta tags for whatsapp, twitter, etc
