I’m thinking about “instant feedback” for my social reader. I’ve already considered some things like immediately showing a post in a channel once it’s been submitted but realistically that occurs when:a post is successfully published to its WebSub hub
I think I can expand the ????? a little bit:
- Your microsub server is subscribed to that channel’s feed via WebSub, so it updates entries for the feed
- Your microsub server notifies your social reader that there is a new post
To be honest, both of those bullets are kind of ??? themselves, as I don’t think any microsub server implementation has added WebSub. There’s an open issue for this for Aperture, for example.
Additionally, the Microsub spec doesn’t actually specify any streaming or real-time updates. There is an open issue for discussion this, though!
You’ve added to the discussion there with some fun extension ideas for EventSource and/or WebSockets, which sounds like a good approach to me!
The Drupal microsub server supports WebSub. It tries to subscribe, and falls back to just polling if there's no hub. Works great, especially with Eternal caturday at the moment, I can instantly enjoy :)
