Phoenix Web Development: Create rich web applications using functional programming techniques with Phoenix and Elixir (鳳凰網頁開發：使用函數式程式設計技術與鳳凰及Elixir創建豐富的網頁應用程式)

Learn to build a high-performance functional prototype of a voting web application from scratch using Elixir and Phoenix
Key Features

• Build a strong foundation in Functional-Programming techniques while learning to build compelling web applications
• Understand the Elixir Concurrency and parallelization model to build high-performing blazingly fast applications
• Learn to test, debug and deploy your web applications using Phoenix framework

Book DescriptionPhoenix is a modern web development framework that is used to build API's andweb applications. It is built on Elixir and runs on Erlang VM whichmakes it much faster than other options. With Elixir and Phoenix, youbuild your application the right way, ready to scale and ready for theincreasing demands of real-time web applications.
This book covers the basics of the Phoenix web framework, showing you how to build acommunity voting application, and is divided into three parts. In thefirst part, you will be introduced to Phoenix and Elixir and understandthe core terminologies that are used to describe them. You will alsolearn to build controller pages, store and retrieve data, add users toyour app pages and protect your database. In the second section youwill be able to reinforce your knowledge of architecting real timeapplications in phoenix and not only debug these applications but alsodiagnose issues in them. In the third and final section you will havethe complete understanding of deploying and running the phoenixapplication and should be comfortable to make your first applicationrelease
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.
What you will learn

• Learn Phoenix Framework fundamentals and v1.3's new application structure
• Build real-time applications with channels and presence
