grabity
Get preview data from a link. Just grab it! 🎣
Grabity looks through Open Graph and Twitter Cards markup to get Information about a link. Its functions will return as much data as they can from the markup. If no og or twitter tags are found, it will default to the content of the
tag and meta description, and if either the title tag or meta description is missing, the returned property will be empty.</p>
