Overview of this book

Phoenix is a modern web development framework that is used to build API’s and web applications. It is built on Elixir and runs on Erlang VM which makes it much faster than other options. With Elixir and Phoenix, you build your application the right way, ready to scale and ready for the increasing demands of real-time web applications. This book covers the basics of the Phoenix web framework, showing you how to build a community voting application, and is divided into three parts. In the first part, you will be introduced to Phoenix and Elixir and understand the core terminologies that are used to describe them. You will also learn to build controller pages, store and retrieve data, add users to your app pages and protect your database. In the second section you will be able to reinforce your knowledge of architecting real time applications in phoenix and not only debug these applications but also diagnose issues in them. In the third and final section you will have the complete understanding of deploying and running the phoenix application and should be comfortable to make your first application release By the end of this book, you'll have a strong grasp of all of the core fundamentals of the Phoenix framework, and will have built a full production-ready web application from scratch.

Building Controllers, Views, and Templates

This chapter is focused on the building blocks of any Phoenix application. By understanding what controllers, views, and templates are (and how they interact), it becomes much easier to build out our web application. We'll tackle this through the perspective of building the first major component of our Live Voting application, and by writing tests to cover the new functionality introduced.

The reader will become proficient in a lot of the basic tenets of using controllers, views, and templates. In addition, the reader will learn how the three pieces fit together via functional composition. Finally, they'll begin diving into writing their first tests covering controllers and views to start enforcing a strong and real-world systems development life cycle (SDLC). This will be from the perspective of building an actual application...
