F[Tg] - Telegramium

Telegram

F[Tg] is a pure functional Telegram Bot API for scala.

This project is a try to provide a comprehensive, well documented and Scala-idiomatic client/server implementations to work with Telegram Bot API. Please refer to telegramium-examples module for usage examples. There is a support both for polling and webhooks. API core is generated from the official documentation, so it is believed to cover all the available methods, entities and to be up to date.

Currently the following backends are supported:

  • http4s
  • cats-effect
  • circe
  • uPickle (MsgPack binary serialization, to be used for storing API messages in DB and sending over network)

You may want to start with Api.scala and EchoBot.scala.

InlineQueryResultMpeg4Gif and InlineQueryResultCachedMpeg4Gif has the same discriminator value which comes from the official docs. Maybe the bug in Tg Bot API itself.

Contribution

I'd love to have more testing and more example bots. Ideas and PRs on telegramium-high - high level interface for the bot API are also highly encouraged.
