Any interest in wrapping this up with a lambda function w/websub for realtime updates?

I've been doing a bunch of reading very recently about websub (pretty much a way to say to some middle server, I'd like updates from this rss feed for the next 5 days) and then you get a post to the endpoint you gave it with encoding.

If so, let me know and I'll draft up a PR.

Sounds cool but just so I’m sold on it—can you elaborate on how/where/what you might use this (for)?

[jacebenson]

so instead of waiting fetching the activities on build, you make a serverless function to handle incoming requests with the new content payload

How: On build register as a subscriber to each topic to a websub server e.g. https://pubsubhubbub.appspot.com/subscribe or https://websubhub.com/ or maybe one you name here https://superfeedr.com/subscriber

• registering is a post call and then web/sub server then makes a call to your callback to verify you infact do want to subscribe
• that requires a serverless function to respond properly which will also take in the payload of the new content
• once registered, websub server makes posts to the callback url provided with the content and a security key in the header so you can verify this is in fact the payload you subscribed to. You could build a new page/link whatever with that payload.
• the websub server only keeps the subscription for a max of ~5 days. so you'd likely have to have to have a build happen on at least that regularity to keep the subscriptions up.

Where/What: This would have a similar use as the existing polling this plugin does, just allow a serverless function to handle incoming posts as well. This would allow for more realtime updates.

I'm not sure all that would need to go into this but I'm a fan of Eleventy, I've been working on a effectively RSS reader thing for the last few years if this is possible in here I'd love to see it. if this is too much for this maybe I should try to make a poc on my 11ty site first.

Sorry for the late circle back here but that does sound awesome! I don’t know that I’d want a serverless dependency for this plugin specifically but I could definitely see an additional package that exposes this functionality!
