I used ‘html-metadata-parser’ in node server to extract meta tag from external link and make link-preview with them.
but when it comes to twitter link, there is no meta data like og:title, og:image.
the thing is when i share twitter link on Slack,Slack makes extended twitter link after twitter authorization.
what should I know to get meta data from twitter link?
[ when i shared twitter link at first ]
[ after twitter authorization on slack ]
