Summary
In this chapter, we built an API that consumes and abstracts the Google Places API to provide a fun and interesting way of letting users plan their days and evenings.
We started by writing some simple and short user stories that described what we wanted to achieve at a really high level without trying to design the implementation up front. In order to parallelize the project, we agreed upon the meeting point of the project as the API design, and we built toward it (as would our partners).
We embedded data directly in the code, avoiding the need to investigate, design, and implement a data store in the early stages of a project. By caring about how that data is accessed (via the API endpoint) instead, we allowed our future selves to completely change how and where the data is stored without breaking any apps that have been written with our API.
We implemented the Facade interface, which allows our structs and other types to provide public representations of them without revealing messy...
