feat: provide link metadata to bluesky post if any

[kai17]

Many sites define social media "cards" using tags like

<meta name="twitter:card" content="summary"></meta>

When I post a link to such a site on twitter, an image/summary are attached. This attachment does not carry over to Bluesky.

I suspect this is because Bluesky (at least on the web) requires an extra click to confirm that one wants to attach the card. It would be great if this confirmation could be given via the API by the script.

Good catch! I'll have a look

I needed the same feature and I added a quick fix in a fork, together with video previews: https://github.com/louisgrasset/touitomamout/compare/main...mcleinn:touitomamout-bskyvid:main

But this is only a quick and dirty solution, if you have time then better wait until @louisgrasset adds the feature to the main repository

I started yesterday to implement the link metadata retrieval to inject them in the bluesky post (if it's not a quote nor have media). Each post will be trying to create a card if it has a link

Thank you, that's great! Not a programmer, so all I can contribute to this wonderful program is bug reports and ideas for new features ;-)

Great. Please note that I ran into issues if the indicated preview picture (og:image) is bigger than 975 kB or so. That especially happens when the og:image is a png. It will fail to upload to Bluesky with an error ("BlobTooLarge") So either you need to ignore the image, choose another one (risky) or scale it down (I am using "sharp" module for that). Also I chose to remove the link from the post afterwards, so not to generate unnecessary chunks - but that is a matter of choice.

Compression work is started, but I'll not merge it with card management.
