Why choose Erlang for web applications? Discover the answer hands-on by building a simple web service with this book. If you’re an experienced web developer who knows basic Erlang, you’ll learn how to work with REST, dynamic content, web sockets, and concurrency through several examples. In the process, you’ll see first-hand that Erlang is ideal for building business-critical services. Erlang was designed for fault-tolerant, non-stop telecom systems, and building applications with it requires a large set of skills. By the end of the book, you’ll have the information you need to build a basic web service and get it running. Explore the power of Erlang and REST for building web services Serve static and dynamic content with the Yaws web server Use different methods for outputting data to user, such as encoding Erlang data structures into JSON or XML Build an application to listen for HTTP requests, process them, store data, and return useful data Go beyond the request-response model—push data to clients with web sockets Use Erlang and Yaws to stream data from the server to a client "A book which is truly needed and will help get Erlang to the next level." —Francesco Cesarini, CEO of Erlang Solutions, author of Erlang Programming.

Elixir and Phoenix are generating tremendous excitement as an unbeatable platform for building modern web applications. For decades OTP has helped developers create incredibly robust, scalable applications with unparalleled uptime. Make the most of them as you build a stateful web app with Elixir, OTP, and Phoenix. Model domain entities without an ORM or a database. Manage server state and keep your code clean with OTP Behaviours. Layer on a Phoenix web interface without coupling it to the business logic. Open doors to powerful new techniques that will get you thinking about web development in fundamentally new ways. Elixir and OTP provide exceptional tools to build rock-solid back-end applications that scale. In this book, you'll build a web application in a radically different way, with a back end that holds application state. You'll use persistent Phoenix Channel connections instead of HTTP's request-response, and create the full application in distinct, decoupled layers. In Part 1, start by building the business logic as a separate application, without Phoenix. Model the application domain with Elixir functions and simple data structures. By keeping state in memory instead of a database, you can reduce latency and simplify your code. In Part 2, add in the GenServer Behaviour to make managing in-memory state a breeze. Create a supervision tree to boost fault tolerance while separating error handling from business logic. Phoenix is a modern web framework you can layer on top of business logic while keeping the two completely decoupled. In Part 3, you'll do exactly that as you build a web interface with Phoenix. Bring in the application from Part 2 as a dependency to a new Phoenix project. Then use ultra-scalable Phoenix Channels to establish persistent connections between the stateful server and a stateful front-end client. You're going to love this way of building web apps! What You Need: You'll need a computer that can run Elixir version 1.5 or higher and Phoenix 1.3 or higher. Some familiarity with Elixir and Phoenix is recommended.
