In this chapter, you’ll build your first Elm application: Photo Groove, a simple photo-browsing web app where users select thumbnails to view larger versions. We’ll create a user interface by using declarative rendering, and manage state by using The Elm Architecture. By the end of the chapter, we will have a fully functioning application—and a code base we can build on for the rest of the book!

JavaScript offers a staggering selection of data flow architectures to choose from, but Elm has just one. It’s called The Elm Architecture, and the Elm Runtime is optimized for applications that follow it. We’ll learn about The Elm Architecture as we add interactivity to Photo Groove.
