Bluesky Comments

Embed Bluesky comments on your website easily.

Installation in a Node.js project as a React component

To use this library in a React project, first install the library:

npm install bluesky-comments

Then import it (and the CSS) in your React app/page/component:

import 'bluesky-comments/bluesky-comments.css'
import { BlueskyComments } from 'bluesky-comments';

And use it in any React component like this:

function App() {
  return (
    <>
      <div>Comments Will Display Below</div>
      <BlueskyComments author="you.bsky.social" />
    </>
  )
}

See the Usage section below for details on the options and API.

Installation on any website via CDN

To add a comments section to any website, follow these steps

1. Add an element to your page where you want the comments to show up

Add something like this to your site:

<div id="bluesky-comments"></div>

You can use whatever id you want, but it has to match the container id used in the getElementById call in the usage step.

2. Add the CSS files

Add the default styles the page <head> somewhere in a base template:

<link rel="stylesheet" href="https://unpkg.com/bluesky-comments@<VERSION>/dist/bluesky-comments.css">

3. Add source maps for React

Add the following importmap to your page anywhere before you use the library:

<script type="importmap">
{
  "imports": {
    "react": "https://esm.sh/react@18",
    "react-dom/client": "https://esm.sh/react-dom@18/client"
  }
}
</script>

4. Import the library and instantiate the component with React in an ES module script:

<script type="module">
  import { createElement } from 'react';
  import { createRoot } from 'react-dom/client';
  import { BlueskyComments } from 'https://unpkg.com/bluesky-comments@<VERSION>/dist/bluesky-comments.es.js';

  const author = 'you.bsky.social';
  const container = document.getElementById('bluesky-comments');
  const root = createRoot(container);
  root.render(
    createElement(BlueskyComments, {
      "author": author,
    })
  );
</script>

See the Usage section below for details on the options and API.

Usage

Examples in this section use the React JSX syntax. If you're installing on a project that doens't use JSX or any build tooling (i.e. a regular website), you can instead use the createElement function and pass the react options in.

For example, the following two examples are equivalent:

React JSX:

<BlueskyComments
  author="you.bsky.social"
  uri="https://bsky.app/profile/coryzue.com/post/3lbrko5zsgk24"
/>

Equivalent without JSX:

root.render(
  createElement(BlueskyComments, {
    author: "you.bsky.social",
    uri: "https://bsky.app/profile/coryzue.com/post/3lbrko5zsgk24",
  })
);

Initializing the library based on the author

<BlueskyComments author="you.bsky.social"  />

If you use this mode, the comments section will use the most popular post by that author that links to the current page.

Initializing the library based on a post URL

<BlueskyComments uri="https://bsky.app/profile/coryzue.com/post/3lbrko5zsgk24" />

If you use this mode, the comments section will use the exact post you specify. This usually means you have to add the comments section only after you've linked to the article.

(Advanced) Providing custom default empty states

You can pass in a onEmpty callback to handle the case where there are no comments rendered (for example, if no post matching the URL is found or there aren't any comments on it yet):

<BlueskyComments
    uri="https://bsky.app/profile/coryzue.com/post/3lbrko5zsgk24"
    author="you.bsky.social"
    onEmpty={
      (details) => {
        console.error('Failed to load comments:', details);
        document.getElementById('bluesky-comments').innerHTML =
          'No comments on this post yet. Details: ' + details.message;
      }
    }
});

(Advanced) Filtering comments

You can pass in an array of filters to the commentFilters option. These are functions that take a comment and return a boolean. If any of the filters return true, the comment will not be shown.

A few default filters utilities are provided:

BlueskyFilters.NoPins: Hide comments that are just "📌"
BlueskyFilters.NoLikes: Hide comments with no likes

You can also use the following utilities to create your own filters:

BlueskyFilters.MinLikeCountFilter: Hide comments with less than a given number of likes
BlueskyFilters.MinCharacterCountFilter: Hide comments with less than a given number of characters
BlueskyFilters.TextContainsFilter: Hide comments that contain specific text (case insensitive)
BlueskyFilters.ExactMatchFilter: Hide comments that match text exactly (case insensitive)

Pass filters using the commentFilters option:

import {BlueskyComments, BlueskyFilters} from 'bluesky-comments';

<BlueskyComments
    // other options here
    commentFilters={[
      BlueskyFilters.NoPins,  // Hide pinned comments
      BlueskyFilters.MinCharacterCountFilter(10), // Hide comments with less than 10 characters
    ]}
/>

You can also write your own filters, by returning true for comments you want to hide:

const NoTwitterLinksFilter = (comment) => {
  return (comment.post.record.text.includes('https://x.com/') || comment.post.record.text.includes('https://twitter.com/'));
}
<BlueskyComments
    // other options here
    commentFilters={[
      NoTwitterLinksFilter,
    ]
/>

(Removed) Legacy installation using `<script>` tags and UMD

Previous versions of this library recommended installing like this:

<script src="https://unpkg.com/react@18/umd/react.production.min.js"></script>
<script src="https://unpkg.com/react-dom@18/umd/react-dom.production.min.js"></script>
<script src="https://unpkg.com/bluesky-comments@<VERSION>/dist/bluesky-comments.umd.js"></script>

And initializing the comments in a standard <script> tag with an init function:

<script>
  document.addEventListener('DOMContentLoaded', function() {
    const uri = 'https://bsky.social/coryzue.com/posts/3jxgux';
    if (uri) {
      BlueskyComments.init('bluesky-comments', {uri});

      // Legacy API (still supported but deprecated)
      initBlueskyComments('bluesky-comments', {uri});
    }
  });
</script>

This option has been removed in version 0.9.0 and new projects should use the ES module syntax above.

Development

To develop on this package, you can run:

npm install
npm run dev

This will set up a local development server with a simple page showing comments, and watch for changes.

You can also run npm run build (build once) or npm run watch (watch for changes) to copy the built files to the dist directory. From there you can reference the files in your own projects.
