Add telegram.bot example and default packages about heroku-buildpack-r HOT 6 CLOSED

Hi @selesnow

Great idea! I'm not familiar with telegram so I had to do some reading up.

I found this blog post on how to deploy a telegram bot to Heroku using Python, so I got an idea of how it could be implemented using R.

I looked at the telegram.bot R package you suggested but it doesn't appear to implement support for receiving webhook requests which would mean having to run on Heroku using a paid for dyno, such as Hobby, in order to run as a background worker process to poll for telegram updates.

I'll have a go at implementing it using polling method and update here my progress.

As a side note, I noticed that telegram.bot doesn't fully implement the telegram API. E.g. The setWebhook method doesn't support all the arguments provided by the API, such as secret_token which would enable webhook requests to be verified.

Hi @selesnow

I've created an example project virtualstaticvoid/heroku-telegram-bot-webhook and created a pull request to the telegram.bot R package with the changes to support webhooks, since Heroku requires a paid-for dyno to run a background polling process (for using the Updater method which requires long polling to work).

For completeness, I've added a second example project virtualstaticvoid/heroku-telegram-bot-updater which uses the Updater class, to run as a background process.

Great, thanks a lot!

For setWebhook method, we can send feature request for telegram.bot author
