Feed

For Hatsu to work, your site needs to have one of the valid JSON / Atom / RSS feeds.

These feeds should be auto-discoverable on the homepage:

<html>
    <head>
        ...
        <link rel="alternate" type="application/feed+json" href="https://example.com/feed.json" />
        <link rel="alternate" type="application/atom+xml" href="https://example.com/atom.xml" />
        <link rel="alternate" type="application/rss+xml" href="https://example.com/rss.xml" />
    </head>
    <body>
        ...
    </body>
</html>

Hatsu detects all available feeds and prioritizes them in order of JSON > Atom > RSS.

JSON Feed

Hatsu uses serde to parse JSON Feed directly, so you can expect it to have first-class support.

Please make sure your feed is valid in JSON Feed Validator first.

JSON Feed Items

Hatsu infers object id from item.url and item.id.

It will use the item.url first, and if it doesn't exist, it will try to convert the item.id to an absolute url.

https://example.com/foo/bar => https://example.com/foo/bar
/foo/bar => https://example.com/foo/bar 
foo/bar => https://example.com/foo/bar

Ideally, your item.id and item.url should be consistent absolute links:

{
	"id": "https://example.com/foo/bar",
    "url": "https://example.com/foo/bar",
	"title": "...",
	"content_html": "...",
	"date_published": "..."
}

JSON Feed Extension

If you can customize your site's JSON Feed, you might also want to check out the Hatsu JSON Feed Extension.

Atom / RSS

Hatsu uses feed-rs to parse XML feeds and convert them manually.
