Telegram Bot API Wrapper written in Elixir (document)

Installation

Add Nadia to your mix.exs dependencies:

def deps do
  [{:nadia, "~> 0.7.0"}]
end

and run $ mix deps.get.

Configuration

In config/config.exs, add your Telegram Bot token like this

config :nadia,
  token: "bot token"

You can also add an optional recv_timeout in seconds (defaults to 5s).

config :nadia,
  recv_timeout: 10

You can also add a proxy support.

config :nadia,
  proxy: "http://proxy_host:proxy_port", # or {:socks5, 'proxy_host', proxy_port}
  proxy_auth: {"user", "password"},
  ssl: [versions: [:'tlsv1.2']]

You can also configure the the base url for the api if you need to for some reason.

config :nadia,
  # Telegram API. Default: https://api.telegram.org/bot
  base_url: "http://my-own-endpoint.com/whatever/",

  # Telegram Graph API. Default: https://api.telegra.ph
  graph_base_url: "http://my-own-endpoint.com/whatever/"

Environment variables may be used as well:

config :nadia,
  token: {:system, "ENVVAR_WITH_MYAPP_TOKEN", "default_value_if_needed"}
