The API endpoint should return Access-Control-Allow-Origin: * for it to work from bookmarklets/usercripts

[necauqua]

So I made a better bookmarklet so that there's less annoying clicks to download the thing (esp. on mobile)

Here's its source, very simple:

fetch('https://fichub.net/api/v0/epub?q=' + encodeURIComponent(location.href))
    .then(r => r.json())
    .then(j => location.href = 'https://fichub.net' + j.epub_url)

However, the /api/v0/epub endpoint does not return a proper CORS header, so the browser blocks the request originating from SB or what have you - it's a common issue with APIs like that.

The fix is to make the endpoint return Access-Control-Allow-Origin: * header.

My personal workaround for now is to have my very own server proxying this request (and adding the header) lul

if you read this you can use my thing until this is fixed ig, works great

THIS DOESN'T WORK!
I messed up my nginx config and sent some background chinese script spam noise hitting me their way, and they rightfully blocked my servers IP (how does one do that? it's just some cloudflare default maybe) sadly.

fetch('https://fichub.necauq.ua?q=' + encodeURIComponent(location.href))
    .then(r => r.json())
    .then(j => location.href = 'https://fichub.net' + j.epub_url)
//
// =>
//
// javascript:fetch("https://fichub.necauq.ua?q="+encodeURIComponent(location.href)).then(r=>r.json()).then(j=>location.href="https://fichub.net"+j.epub_url);
