Phoenix Web Development

By: Brandon Richey

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.

Previously, we finished all of the remaining work that we needed to get our application polished up and tested across the board. Our application is pretty solid and we're finally at a point where we can start diving into some of the truly amazing features of Phoenix: the out-of-the-box support for web sockets! Before we can dive too deep into how to start implementing these in Phoenix, we should probably take a quick sidebar to discuss what web sockets even are!

Web Sockets are means of passing data back and forth through a dedicated line (or socket) that allows for real-time communication back and forth between a client (your web browser) and the server (your Phoenix application). This information can either be solely limited to communication with a single client or multiple clients simultaneously (a broadcast message, similar to chat rooms). This...
