We spent the whole Chapter 2 defining what we will be building (an email newsletter!), narrowing down a precise set of requirements. It is now time to roll up our sleeves and get started with it.
This chapter will take a first stab at implementing this user story:
> As a blog visitor,
> I want to subscribe to the newsletter,
> So that I can receive email updates when new content is published on the blog.
We expect our blog visitors to input their email address in a form embedded on a web page. The form will trigger an API call to a backend server that will actually process the information, store it and send back a response.
This chapter will focus on that backend server - we will implement the /subscribe POST endpoint.
