This is part of building a chat app with Phoenix Channels workshop. In this part we will use Elixir to build a chat bot.

Create a new Bot application

Remember in part 1 we generated root for the umbrella application? Generate new application for chat bot:

$ cd chatter/apps
$ mix new bot

Using umbrella applications provided by Elixir we can desing for deletability, one of the great ideas Greg Young was talking about. Let's stop here for a second and think about boundaries, microservices and how to get it right.

Create new umbrella application

$ mix new chatter --umbrella
$ cd chatter

Create new Phoenix Project

$ cd apps

	I have a challenge of transforming the data from 1 state to another. I have written my implementation, but I know it could be done, just could’t figure it out. I was looking into using Streams, but struggling to implement it. Any suggestions?

	input = [["foo", 56, "0", "1"],
	["bar", 34, "2", "3"],
	["bla", 90, "2", "1"],
	["hey", 10, "4", "1"]]

	output = [%{"0" => [56]},
	%{"2" => [90, 34]},
	%{"4" => [10]}
