• Add URLs to posts with automatic preview card generation
• Specify post language settings
• Authenticate with Bluesky using an identifier and password
• Support for session management and reuse
• Automatically generate tags, mentions and URL cards
• Customizable base URI for different Bluesky instances
• Embed external content with rich preview cards

Getting Started

Prerequisites

• .NET SDK (compatible with the version used by the project)
• An account on Bluesky with an identifier and password

Installation

To use the X.Bluesky library in your project, include it as a dependency in your project's file (e.g., csproj).

See the NuGet package page for the latest version.

Usage

Basic Usage

var identifier = "your.bluesky.identifier";
var password = "your-password-here";

IBlueskyClient client = new BlueskyClient(identifier, password);

// Simple text post
await client.Post("Hello from X.Bluesky!");

// Post with hashtags
await client.Post("Read this post from #devdigest: https://yourlink.com/post/123");

// Post with URL (generates preview card)
await client.Post("Read this post!", new Uri("https://yourlink.com/post/123"));

// Create a client
var client = new BlueskyClient(
identifier,
password,
reuseSession: true,
baseUri: new Uri("https://bsky.social"));

// Create a fully customized post
var post = new Post
{
    Text = "Check out this image with my thoughts on #AI development!",
    Images = new[]
    {
        new Image
        {
            Content = File.ReadAllBytes("path/to/image.jpg"),
            MimeType = "image/jpeg",
            Alt = "A diagram showing AI architecture"
        }
    },
    Url = new Uri("https://yourblog.com/ai-article"),
    Languages = new[] { "en" },
    GenerateCardForUrl = true  // Generate a rich preview card for the URL
};

// Post to Bluesky
await client.Post(post);

Advanced Usage with Post Object The core method of the library is Post(Models.Post post) which gives you full control over your post content:

// Create a client
var client = new BlueskyClient(
identifier,
password,
reuseSession: true,
baseUri: new Uri("https://bsky.social"));

// Create a fully customized post
var post = new Post
{
    Text = "Check out this image with my thoughts on #AI development!",
    Images = new[]
    {
        new Image
        {
            Content = File.ReadAllBytes("path/to/image.jpg"),
            MimeType = "image/jpeg",
            Alt = "A diagram showing AI architecture"
        }
    },
    Url = new Uri("https://yourblog.com/ai-article"),
    Languages = new[] { "en" },
    GenerateCardForUrl = true  // Generate a rich preview card for the URL
};

// Post to Bluesky
await client.Post(post);

The Post object allows you to combine multiple elements like text, images, URLs, and metadata in a single post. This is especially useful for more complex posts that require fine-grained control over the content and presentation.
