@jeffweiss I love this idea! I'll start thinking about an API for this.

from hedwig.

@scrogson I'm wondering if it would be possible to delegate somehow the message to the adapter. As each service has its own types of messages. For example in telegram, to mention one, you can send keyboards.

I'm really asking, as a clarification for a doubt I have, I don't know if it's already in Hedwig. But I'd be a really nice API if not.

Currently at work we've developed something with AWS, kinda like a message gateway, a main entry point for receiving and sending messages (for messenger, kik, line, twilio & telegram), but this delegates to the services or adapters of this services, thus we can send special keyboards, special images, or custom responses without having any kind of limitation.

We've been wanting to change it, completely rewrite it in Elixir, so we can take advantage of what it gives us, like amazing fault tolerance software it's built upon. We were looking around, investigating when we came upon Hedwig, and we really think it could be the answer we've been looking.

Thanks for your attention.
Hope I've explained myself.

@behind-design what exactly do you have in mind?

The response messages do make their way back to the adapter which is responsible for transforming the %Hedwig.Message{} into whatever is required for the underlying service.

I was wondering if type field on %Hedwig.Message{} would be enough to distinguish if responder wants to send normal message or message with attachment (e.g. Slack 'message.attachment' type) or file. Adapters can use pattern matching to compose message needed for their specific messaging protocol.

Is this good idea? I am Elixir/Erlang beginner, so I am not sure if there is better/more idiomatic way how to solve this in Elixir.
