Elixir Discord Library

Nostrum

An Elixir library for the Discord API.

It is highly recommended to check out the documentation first. It includes all of the information listed here and more.

Installation

It is recommended to use a stable release by specifying a published version from Hex:

def deps do
  [{:nostrum, "~> 0.6"}]
end

For stable installations, documentation can be found at https://hexdocs.pm/nostrum. However, if you want the latest changes and help test the library, you can also install directly from GitHub:

def deps do
  [{:nostrum, github: "Kraigie/nostrum"}]
end

Documentation for master can be found at https://kraigie.github.io/nostrum/.

Edit or create your config file at /config/config.exs. To run Nostrum you need the following two fields:

config :nostrum,
  token: "666" # The token of your bot as a string

Note that due to Discord API changes, in order to receive message content (e.g. for non-slash commands or moderation tools), you need to have the "Message Content Intent" enabled on your Bot's application settings, and the :message_content intent specified in the [:nostrum, :gateway_intents] configuration key.

For more information about the differences between dev and stable as well as additional config parameters, please see the documentation.

Example Usage

The below module needs to be started in some fashion to capture events. See here for a full example.

defmodule ExampleConsumer do
  use Nostrum.Consumer

  alias Nostrum.Api

  def start_link do
    Consumer.start_link(__MODULE__)
  end

  def handle_event({:MESSAGE_CREATE, msg, _ws_state}) do
    case msg.content do
      "ping!" ->
        Api.create_message(msg.channel_id, "I copy and pasted this code")
      _ ->
        :ignore
    end
  end

  # Default event handler, if you don't include this, your consumer WILL crash if
  # you don't have a method definition for each event type.
  def handle_event(_event) do
    :noop
  end
end

Although it's recommended to run under a supervisor, you could start it from iex.

  iex()> ExampleConsumer.start
  {:ok, #PID<0.208.0>}
