A convenient Telegram Bot API framework.

Usage

require "tele"

      parse_mode: "HTML",
    )
  end
end

class ExampleBot < Tele::Bot
  @@name = "ExampleBot"

  def handle(update)
    if message = update.message
      Start
    end
  end
end

bot = ExampleBot.new("BOT_API_TOKEN", 5000, Logger.new(STDOUT))
bot.set_webhook(URI.new(scheme: "https", host: "example.com"))
bot.listen

Development

I love Crystal because if it compiles it means the program will definitely work. This reduces the amount of tests to be written. I personally write tests for SQL queries only. 😄

So there are no any tests for Tele at the moment.
