Question 1

How do I set up webhooks with Nadia?

Accepted Answer

Nadia does not provide built-in webhook handling. You need to use an HTTP server like Phoenix or Plug to receive updates, then call Nadia functions to process them, as indicated by the lack of webhook examples in the documentation.

Question 2

Nadia vs ExGram: which is better for Telegram bots in Elixir?

Accepted Answer

Nadia focuses on a straightforward, idiomatic API wrapper with full coverage, while ExGram offers more features like middleware and plugins. Choose Nadia for simplicity and direct API mapping, or ExGram for extended bot framework capabilities.

Question 3

How to send images or files using Nadia?

Accepted Answer

Use methods like send_photo or send_document with appropriate parameters, as Nadia supports all Telegram API methods. Refer to the Nadia documentation for function signatures and examples based on the Telegram API.

Question 4

Does Nadia handle rate limiting or retries automatically?

Accepted Answer

No, Nadia does not include automatic rate limiting or retry mechanisms. Developers must implement custom logic based on error responses, such as those from structured error handling, to manage Telegram's API limits.

Question 5

Can I use Nadia with environment variables for tokens?

Accepted Answer

Yes, Nadia supports configuration via environment variables, as shown in the README with examples like {:system, "ENVVAR_WITH_MYAPP_TOKEN"}, making it easy to manage secrets in deployment.

Question 6

What's the performance like for high-volume bots with Nadia?

Accepted Answer

Performance depends on Elixir's concurrency and HTTP client efficiency. Nadia is a wrapper over HTTP calls, so for high-throughput bots, you may need to optimize with connection pooling or async handling, as it doesn't include built-in optimizations.
