Telegramium-2.49.0

Telegramium 2.49.0 released.
It supports all methods and entities of Telegram Bot API v4.9.

This MAJOR release introduces significant breaking changes.

• You can perform a request to the Bot API while sending an answer to the webhook.
• All Update types are supported.

An excerpt from the documentation:

How to use

Create the dependency by adding the following lines to your build.sbt:

libraryDependencies += "io.github.apimorphism" %% "telegramium-core" % "2.49.0"
libraryDependencies += "io.github.apimorphism" %% "telegramium-high" % "2.49.0"

Imports:

import telegramium.bots.high._
import telegramium.bots.high.implicits._

Use the Methods fabric to create requests. You will need an instance of the BotApi class to execute them:

BlazeClientBuilder[F](ExecutionContext.global).resource.use { httpClient =>
  implicit val api: Api[F] = BotApi(http, baseUrl = s"https://api.telegram.org/bot$token")
  val bot = new MyLongPollBot()
  bot.start()
}

Long polling

class MyLongPollBot[F[_]: Sync: Timer]()(implicit api: Api[F]) extends LongPollBot[F](api) {
  override def onMessage(msg: Message): F[Unit] =
    Methods.sendMessage(chatId = ChatIntId(msg.chat.id), text = "Hello, world!").exec.void
}

LongPollBot and WebhookBot extend the Methods trait so you can call sendMessage directly.

Webhooks

class MyWebhookBot[F[_]: ConcurrentEffect: ContextShift: Timer](port: Int, url: String, path: String)(
  implicit api: Api[F]
) extends WebhookBot[F](api, port, url, path) {
  override def onMessage(msg: Message): F[Unit] =
    sendMessage(chatId = ChatIntId(msg.chat.id), text = "Hello, world!").exec.void
}

You can also perform a request to the Bot API while sending an answer to the webhook:

override def onMessageReply(msg: Message): F[Option[Method[_]]] =
  Sync[F].pure(Some(sendMessage(chatId = ChatIntId(msg.chat.id), text = "Hello, world!")))
