Feedmaker: URL + CSS selectors = RSS feed

Glad you’re find the tool interesting! A short blog post behind it: https://kschaul.com/post/2023/04/16/feedmaker-quickly-genera...

And the GitHub url (hopefully easy to host your own instance): https://github.com/kevinschaul/feedmaker

Looks like you're hosting this on fly.io - PAYG model. You could probably host this for free on Cloudflare Workers; 100k requests/day on the free tier; static content (the homepage) is free & unlimited.

Edit: The catch is the 10ms CPU cap per request - you'd need a super lean implementation. Django's too heavy for that.

		Python alone is many milliseconds to start. Unless they give you some allowances for interpreter overhead.

The good news: made it to the front page.

The bad news: so did the 503 page.

In some ways a good thing, no? Shows you've got work to do on optimisation for large audiences. A free stress test (unless you're on a host that charges per hit or bandwidth excess), as you will.

Did load eventually for me, thought it was broken as no styles but looks like it's intentional.

https://github.com/RSS-Bridge/rss-bridge is what I've been using for the same purpose.

I love this.

Has anyone tested to see if it works with Blogtrottr which will email you whenever there's a new item in an RSS feed?

Just since this doesn't seem like it even includes a date field in the RSS? And of course no guid. So I'm wondering how compatible it winds up being.

		Dates shouldn't matter. The feed has ID elements which is what identify entries. Atom has no guid element. So I would expect this to work with any reader.

I made a CGI program that ran CSS selectors against URLs and returned the output. I debated making it public and then realized I probably didn't want to run an open proxy. I'm curious how long this will last.

Not the same but this gives me an idea… what if there was a map reduce for doms as a web primitive. Like imagine if I could make a dom (or feed) that was some selection and transformation of another dom
