If you like, you can also rely on CDN services like esm.sh or JSDelivr.

Usage

Bluesky posts can be embedded like so:

<bluesky-post src="at://pfrazee.com/app.bsky.feed.post/3kj2umze7zj2n">
	<blockquote class="bluesky-post-fallback">
		<p dir="auto">angel mode</p>
		&mdash; Paul Frazee 🦋 (@pfrazee.com)
		<a href="https://bsky.app/profile/pfrazee.com/post/3kj2umze7zj2n">January 16, 2024</a>
	</blockquote>
</bluesky-post>

Adding a fallback content like above is heavily recommended for progressive enhancement.

Attributes

• src Required
  A bsky.app URL of the post.
  Heavily recommended that the URL points to a DID instead of a handle, otherwise, it would have to resolve the handle into DID first (and suffer from issues like users changing their handles, etc)
  An example of such URL would be: https://bsky.app/profile/did:plc:ragtjsm2j2vknwkz3zp4oxrd/post/3kj2umze7zj2n
• contextless Optional
  Prevent displaying of context when src points to a reply.
• allow-unauthenticated Optional Allow displaying of posts even if author has opted for no public previewing.
• service-uri Optional
  URL to an AppView service, defaults to https://public.api.bsky.app

Events

• loaded
  Fired when the embed has successfully loaded the post
• error
  Fired when the embed fails to load the post

SSR usage

The core of this package is a static HTML renderer, so long as your framework of choice has the means to deal with declarative shadow DOM, then it's possible to generate a completely static embed without any JavaScript in the client.

See this repository for an SSR demo made in Astro.
