I'm getting a blank page. Looking at the source, there is no static content on it, only JS. I have JS turned on, but it seems CORS is blocking loading of JS.

  Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://static.cloudflareinsights.com/beacon.min.js/v652eace1692a40cfa3763df669d7439c1639079717194. (Reason: CORS request did not succeed).
  None of the “sha512” hashes in the integrity attribute match the content of the subresource.

Edit: works in Chromium, but not in Firefox.

Weird...

I did recently switch to hosting through a Cloudflare Worker, so maybe it's a caching issue. Is it possible you've viewed the site before? If so maybe you have an old version of the index.html file in your browser cache that's linking to the wrong assets.

Either way thanks for reporting — I'll look into it!

I've tracked down the root cause: I needed to disable two uBlock Filters in order to successfully load the page: Fanboy's Annoyance and Fanboy's Social. It seems that they block some JS related to social buttons (https://japan-dev.com/assets/socialButton.9ddbb1cc.js) and that makes the rest of JS responsible for the rest of the page to not execute (due to a failed request).

Sorry for the false flag.

Doesn't load in Safari for me with ad blockers.

Interesting, can you let me know which ad blocker so I can try to reproduce?

I think it's the same social media filters that did it. For reference, I'm using AdGuard on iOS and have the social media button filters on.

Oh wow thanks for checking, that's helpful to know.

I should probably restructure things so that one component failing doesn't bring down the whole site if I can...

I'm on Windows, blank page with Firefox and uBlock origin. Works fine on Ms Edge (no ad blocker).

Yeah, I still get a blank page. (I hope you don't expect us to disable uBlock Origin to see some social media buttons because that's never happening!).

Yes, you definitely should. Adblockers is just one reason why networks requests don't always go through successfully expected.

I also get a sha512 mismatch on the CF script.

(Degrading gracefully so content is readable even without client-side JS is an even better idea but that obv takes more effort to sort out on an existing SPA)

Looking forward to reading your article but my reverse-engineering stops here for now (:

Same issue, looks like some uBlock Origin filter list is blocking it.

It works in Firefox for me
