If CORS weren't an issue, it could've been done in 1/10th of that time. But if that were the case, there would've already been tons of web-based RSS readers available.
Anyway, the goal of this project is to help foster interest in indie blogs and help a bit with discovery. Feel free to submit your blog if you'd like!
If anyone has any questions, I'd be happy to answer them.
In my opinion, that’s a bigger problem than CORS. Proxyless web feed reader is a lost cause, you’re wasting your time because only a small minority are ever going to support it. But that opacity and transition nonsense gratuitously slows down page loading for everyone, and hides content completely for those that aren’t running JS.
(What I would also like to know is: how come this is the third time I’ve seen exactly this—each block of content having this exact style attribute—in the past month, when I don’t remember encountering exactly it before?)
And to answer your question, you're seeing that kind of styling so frequently because it's likely part of Framer Motion, an extremely popular animation library
https://www.npmjs.com/package/framer-motion https://www.npmjs.com/package/motion
So, basically, any URI that I need to resolve goes tries first to fetch directly and it falls back to making the request through the proxy if I get any type of authentication error.
Why would anyone do this, so their content can be easily read elsewhere potentially with a load of ads surrounding it?
This seems to really reason through only the happy path, ignoring bad actors, and there'll always be bad actors.
CORS also doesn't prevent a popular website with a personal vendetta[0] against a blogger from DDOSing the blog with their visitors, since CORS doesn't block requests from being sent.
For a purely static website, there shouldn't be any risk from enabling CORS.
True, but the bad actors can defeat any security mechanism you put in place with a proxy, or a copy'n'paste, so the downside risk is pointless worrying about. The upside of allowing traffic is that your content that you presumably want people to read can be read by more people. For all but the most popular blogs that's probably a net benefit.
