rocksky — Gleam SDK

Gleam bindings to the shared Rocksky Rust core (rocksky-sdk) via the rocksky_erl Rustler NIF: AppView reads, AT Protocol PDS writes (scrobble, like, follow, shout) and the identity hashes — the same engine behind every Rocksky SDK. Targets Erlang.

Installation

gleam add rocksky

rocksky depends on rocksky_erl, whose loader fetches the native library from the GitHub release on first use (checksum-verified). For monorepo dev, build it with ../erlang/build-core.sh and use the local path dep in gleam.toml.

Quick start

import rocksky/client

pub fn main() {
  // Reads — use the default AppView (https://api.rocksky.app).
  // Envelope calls return Dynamic ({ok, value} | {error, message}); decode with
  // gleam/dynamic.
  echo client.global_stats()
  echo client.top_tracks(10, 0)

  // Writes — log in once (session persisted at the given path).
  let agent = client.login("session.json", "alice.bsky.social", "app-password")
  echo client.follow(agent, "did:plc:rlwgbwqdknilpxxep5gvzc3y")
}

API

Reads

profile(actor), scrobbles(actor, limit, offset), top_tracks(limit, offset), global_stats() — each returns Dynamic. To target a custom AppView endpoint, use the *_at variant with a trailing endpoint URL (e.g. global_stats_at("https://…"), top_tracks_at(limit, offset, "https://…")).

Writes

login(session_path, identifier, password) → an opaque Agent. Then like(agent, uri, cid), follow(agent, did), shout(agent, subject_uri, subject_cid, message), refresh_session(agent).

Identity hashes

song_hash(title, artist, album), artist_hash(album_artist) — lowercase-hex SHA-256, identical to the server and every other Rocksky SDK.

Example

gleam run -m examples/native_core
