How we built ToDoBot for Slack in 3 days

ToDoBot was an experimental side-project, so we worked on it in between meetings, customer calls, on a commute, and late commute. We wanted the user to be able to perform multiple actions so, we had to resort to the “overflow” element. We faked checkboxes with an emoji for now, hoping that Slack would one day implement them and we’ll make our app behave like a proper todo. We spent the entire Day 2 coding the bot logic. We then add every message to the ToBot that represents the current state a person’s todo list.
