README

An small PHP library for Bluesky social using the AT Protocol.

Usage

Install

Installing using composer is suggested

composer require potibm/phluesky

You will need a PSR-7, PSR-17 and PSR-18 client or adapter from this list. For development symfony/http-client and nyholm/psr7 are used.

The HTTP service discovery will do the magic. In most cases no additional steps are required.

$postService = new \potibm\Bluesky\BlueskyPostService($api);

$post = \potibm\Bluesky\Feed\Post::create('✨ example mentioning @atproto.com to share the URL 👨‍❤️‍👨 https://en.wikipedia.org/wiki/CBOR.');

$response = $api->createRecord($post);
