Question 1

How do I set up webhooks with telegram-bot-ruby?

Accepted Answer

The library doesn't include a webhook server; you need to build your own using a web framework like Sinatra or Rails and handle HTTP callbacks manually. The README points to an example repository for guidance, but it requires additional setup and deployment effort.

Question 2

telegram-bot-ruby vs python-telegram-bot: which should I use?

Accepted Answer

Choose based on your language stack: telegram-bot-ruby is ideal for Ruby environments with its idiomatic interface, while python-telegram-bot offers similar features in Python with a larger community. Consider team expertise and integration needs for existing Ruby projects.

Question 3

How to handle inline queries and callbacks in this library?

Accepted Answer

Use the provided types like InlineQuery and CallbackQuery to parse updates, then respond with answer_inline_query or send_message, as shown in the inline bots example. You'll need to manually route message types based on the update object.

Question 4

Can I use telegram-bot-ruby with Rails for a production bot?

Accepted Answer

Yes, but you'll need to integrate it into Rails' request-response cycle for webhooks or run it as a separate service for polling. There's no built-in Rails generator or scaffolding, so expect to write custom controllers or background jobs.

Question 5

How to upload a file like a photo using this gem?

Accepted Answer

Call methods like send_photo with a Faraday::Multipart::FilePart object, specifying the file path and MIME type, as detailed in the file upload section. This abstracts the multipart form data handling required by the Telegram API.

Question 6

What's the performance impact for high-traffic bots with this library?

Accepted Answer

Performance depends on Ruby's concurrency model and your server setup; for long polling, it handles updates sequentially, which may bottleneck under heavy load. Consider using webhooks with a scalable server and optimizing database calls for state management.
