APOD Slack Unfurls

[bgreenlee]

We're big fans of APOD at my company, and we have a #space Slack channel where we automatically post a link to APOD every morning. However, the unfurl you get in Slack isn't terribly interesting:



However, Slack will look for OpenGraph metadata headers in the page and use those if it finds them. I wrote a little app that uses the NASA APOD API to generate the headers and then automatically redirect to the APOD page. This is what it looks like in Slack:



Ideally, the APOD page could incorporate these headers and this hack wouldn't be necessary. In the meantime, feel free to use my app at https://astroslack.fly.dev, or create your own API key and host it yourself.

Cheers,
