Tele::Broadcast

A broadcasting module for Tele.cr.

Installation

Add this to your application's shard.yml:

dependencies:
  tele-broadcast:
    github: vladfaust/tele-broadcast.cr
    version: ~> 0.1.3

Usage

Read some docs when you need.

Tele::Broadcast is agnostic of ORM structure, you just pass a list of Tele::Requests and an list of recipients chat IDs and run the Woker. You can either create a custom CLI for broadcasting from the local machine or develop a web-interface.

Client

The client allows to schedule broadcasts:

require "tele/requests/send_message"
require "tele-broadcast/client"
require "tele-broadcast/repositories/redis"

logger = Logger.new(STDOUT).tap(&.level = Logger::DEBUG)
repo = Tele::Broadcast::Repositories::Redis.new(Redis.new, logger, "example_bot:broadcast:") # Don't forget to add a colon in the end of namespace

client = Tele::Broadcast::Client.new(repo, logger)

request = Tele::Requests::SendMessage.new(chat_id: 0, text: "Hello from Tele::Broadcast!")
recipients = [116543174, 155633478] of Int32 # A list of Telegram IDs

client.broadcast(requests, recipients)

# => INFO -- : Added payload #1 to the broadcasting queue

Check out examples/client.cr and try it yourself:

crystal /examples/client.cr -- --text="Hola!" -r <Your Telegram ID>

Please not that you have to contact the bot at least once so it can send you messages.

Worker

The worker periodically checks for new broadcasts and handles them:

require "tele-broadcast/worker"
require "tele-broadcast/repositories/redis"

logger = Logger.new(STDOUT).tap(&.level = Logger::DEBUG)
repo = Tele::Broadcast::Repositories::Redis.new(Redis.new, logger, "example_bot:broadcast:") # Don't forget to add a colon in the end of namespace

worker = Tele::Broadcast::Worker.new("BOT_API_TOKEN", repo, logger)
worker.run

# =>  INFO -- : Tele::Broadcast::Worker worker is running!
# =>  INFO -- : Started broadcasting payload #1 to 2 recipients...
# => DEBUG -- : Recipient 116543174 has blocked the bot, skipping
# => DEBUG -- : Sending request #727 to 155633478...
# => DEBUG -- : Delivered request #727 in 0.29s
# =>  INFO -- : Done broadcasting payload #1 in 0.29s!

Try it yourself:

crystal /examples/worker.cr -- -t <BOT_API_TOKEN>

Development

There are tests! So please run crystal spec while developing.
