Phoenix is an Elixir web framework for building productive, reliable applications with the performance to take on the modern computing world. Together, we’ll review what makes Phoenix great and how it uses Elixir to optimize code for performance – without sacrificing programmer productivity. Along the way, we’ll see neat features like live-reload and generators and how Phoenix’s realtime layer takes on the modern web.
Phoenix is an Elixir framework for building scalable web applications with realtime connectivity across all your devices. Together, we’ll take a guided tour of the framework, going from the very basics, to building our own realtime applications. You’ll see the framework’s foundations, core components, and how to use Phoenix to write powerful web services.
Tutorial objectives:
We’ll start by exploring the foundations of the framework in Elixir’s Plug library, followed by the core components of Phoenix’s Router and Controller layers. Next, we’ll review the View layer and build an application together as we learn each concept. We’ll finish by using the PubSub layer to add realtime functionality to our application. Along the way, attendees will see how to apply advanced features like router pipelines and plug middelware and receive tips on how to structure a Phoenix application for real-world services.
Prerequisites:
The audience for this talk is any Elixir or Erlang programmer looking to dive into Phoenix and learn how to build powerful applications quickly and easily. Attendees should have an introductory level experience with Elixir or Erlang and the ability to run Elixir on their laptops.
We'll live-code the game of Tetris from scratch, culminating in a browser-based tetris game that multiple audience members can connect to and control collaboratively.
Target audience:
- Elixir beginners through intermediates
Have you ever wondered about why you might use multiple levels of supervisors, or when you might use a strategy other than one_for_one? What about practical examples of how you might do a live code update? Or how to send code down to a node that just joined a cluster? Rudimentary, but effective, failover between cluster nodes? I created an Internet Relay Chat (IRC) bot-OhaiBot-to explore each of these topics. I'll do a walkthrough of the design, running, and update of the bot, focusing not necessarily on OhaiBot, but on why and how I came to certain solutions. No previous knowledge of IRC is necessary. Audience participation, particularly for the clustering aspects, is encouraged.
Target audience:
- Beginners
