#59: Getting State from a GenServer

#56: Completing Order History and Receipt Pages
In this episode we’ll build on the foundation we setup in part 1. We’ll populate our ‘order history’ and ‘receipt’ pages with actual data and make them accessible to our customers.
#55: Defining Routes and Structuring Data
In this episode we get started building an order history page. We’ll look at how our application is structured, how we can fetch data from an API to build our receipts, and how to structure that data.
