FSharp.ATProto.Crypto 0.4.0

FSharp.ATProto

A native F# library for Bluesky and the AT Protocol. Built from the ground up in F#. No C# wrappers. Functional-first.

Install

dotnet add package FSharp.ATProto.Bluesky

Quick Example

open FSharp.ATProto.Bluesky

taskResult {
    let! agent = Bluesky.login "https://bsky.social" "my-handle.bsky.social" "app-password"
    let! post = Bluesky.post agent "Hello from F#!"
    let! like = Bluesky.like agent post // PostRef -> LikeRef (the compiler prevents mix-ups)
    let! reply = Bluesky.replyTo agent "Nice thread!" post // thread root resolved automatically
    let! _ = Bluesky.undo agent like // generic undo — works on any ref type
    return reply
}
// : Task<Result<PostRef, XrpcError>> — no exceptions, ever

Design

• If it compiles, it's correct -- distinct types for every domain concept (PostRef, LikeRef, FollowRef, BlockRef...) mean the compiler catches your mistakes.
• The library handles protocol complexity -- thread roots, rich text facets, chat proxy headers -- all resolved automatically.
• Results, not exceptions -- every public function returns Result. No failwith, no try/catch.
• Rich domain types -- PostRef, Profile, FeedItem, ConvoSummary, Page<'T>, and more. Plus convenience functions for search, bookmarks, muting, notifications, and moderation.
• Generated from the spec -- 324 Lexicon schemas compiled to F# types + 237 typed XRPC endpoint wrappers.

Features

• Posts -- create, reply, quote, delete, with automatic rich text detection
• Rich text -- mentions, links, and hashtags detected and resolved automatically
• Images -- upload and attach with typed ImageMime and alt text
• Social graph -- follow, block, like, repost, mute, with typed refs and generic undo
• Feeds -- timeline, author feed, actor likes, bookmarks
• Profiles -- get, search, typeahead, batch fetch, upsert
• Chat / DMs -- conversations, messages, reactions, with automatic proxy headers
• Notifications -- fetch, count unread, mark seen
• Moderation -- report content, mute threads, mod lists, and a full moderation engine
• Identity -- DID resolution, handle verification, PDS discovery
• Lists -- create and manage lists and starter packs
• Preferences -- saved feeds, muted words, content filtering
• Streaming -- real-time events via Jetstream and Firehose
• Video -- upload and post video content
• Pagination -- lazy IAsyncEnumerable paginators for timeline, followers, notifications
• OAuth -- OAuth 2.0 client with DPoP/PKCE, plus authorization server
• Server-side -- feed generator framework, XRPC server, service auth
• Full XRPC access -- all 237 Bluesky endpoints available as typed wrappers
