'Components' is the folder where we store all of our components.
We can imagine the
components folder as "drawer" which holds all of the components in our workspace.
Each component has a standard Clojure project structure; with a
project.clj file, a
readme.md file, a
resources folder, a
src folder, and a
test folder. Each component is a project to allow us to compile them as individual artefacts, which guarantees that they are de-coupled from all other building blocks.
As you hopefully remember from the block metaphor, a component's interface is where it exposes its functionality to other building blocks. A component's interface is simply a namespace, in this case called
The implementation namespaces are where a component implements the functionality that's exposed by its interface.
