ATProto

Implementation of the ATProtocol client spec in Elixir.

Installation

The package can be installed by adding atproto to your list of dependencies in mix.exs:

def deps do
  [
    {:atproto, "~> 0.1.0"}
  ]
end

The docs can be found at https://hexdocs.pm/atproto.

Usage

ATProtocol uses XRPC for API communication, so we need to build an XRPC.Client and then we can call ATProto or ATProto.BSky functions.

Unauthenticated example:

XRPC.Client.new("https://bsky.social")
|> ATProto.resolve_handle("atproto.com")

{:ok, %{"did" => "did:plc:ewvi7nxzyoun6zhxrhs64oiz"}}

Authenticated example:

client = XRPC.Client.new("https://bsky.social")

{:ok, session} = ATProto.create_session(client, "[email protected]", "xxxx-xxxx-xxxx-xxxx")

client
|> Map.put(:access_token, session.access_jwt)
|> ATProto.BSky.get_profile("atproto.com")

{:ok,
 %ATProto.BSky.ProfileViewDetailed{
