Question 1

How do I handle different Slack message types with Elixir-Slack?

Accepted Answer

Define pattern-matching callback functions in your bot module using handle_event to match on message types like %{type: 'message'}, and include a fallback clause to avoid crashes from unhandled events, as shown in the README examples.

Question 2

Elixir-Slack or Slackex: which is better for building Slack bots in Elixir?

Accepted Answer

Elixir-Slack offers comprehensive Web API coverage and a behavior-based framework, making it ideal for full-featured integrations. Slackex might be lighter but less feature-rich; choose Elixir-Slack if you need extensive API access and structured bot development.

Question 3

How to test a Slack bot built with Elixir-Slack?

Accepted Answer

Use the testing configuration to override the default Slack URL with a fake server endpoint, allowing integration tests without hitting Slack's APIs, as described in the README's Testing section.

Question 4

Does Elixir-Slack support Slack's Events API?

Accepted Answer

Primarily no—it focuses on the RTM API for real-time events via WebSockets. For Events API with HTTP callbacks, you'd need to handle incoming requests separately, as the library doesn't natively manage them.

Question 5

How to send messages programmatically outside event handlers in Elixir-Slack?

Accepted Answer

Leverage the handle_info callback to implement an external API, sending messages to the bot process using Elixir's send/2 function, as demonstrated in the README with examples like send rtm, {:message, ...}.

Question 6

What's the best way to use multiple Slack tokens with Elixir-Slack?

Accepted Answer

Configure tokens globally via config or pass them as optional_params in individual API calls, providing flexibility for multi-tenant or scoped authentication, as explained in the Web API usage.
