Basics Of Elixir and Phoenix
- 1. Basics Of ElixirAnd Phoenix Onorio Catenacci, IT Trainer United Shore, Troy, MI
- 2. 2 Agenda What Is Elixir? WhereCan I Get Elixir? How Do I Get Started With Elixir? What’s Mix? How Do I Create An Elixir App? What Is Phoenix? Where Can I Get Phoenix? How Do I Start To Create A Phoenix App? Summary/Review
- 3. 3 What Is Elixir? Elixiris a highly-scalable, fault-tolerant, actor-model based functional programming language which is somewhat descended from Erlang, Ruby and Clojure.
- 4. 4 What Is Elixir? Highly-scalable:Literally thousands of BEAM processes running concurrently. Fault-tolerant: Each BEAM process is separate. Failures in BEAM processes are isolated.
- 5. 5 What Is Elixir? Actor-model:What OO should have been. Functional Programming: Everything is immutable by default—much safer in multi-process environment.
- 6. 6 What Is Elixir? Erlang:BEAM and OTP Ruby: Syntax Clojure: Macro system
- 7. 7 What Is Elixir? OperatingSystem BEAM Elixir Erlang Erlang Abstract Format
- 8. 8 Where Can IGet Elixir? Start with www.elixir-lang.org Install link Will need to install Erlang first
- 9. 9 Where Can IGet Elixir? Mac: HomeBrew, MacPorts, Build From Source Linux: Package Manager, Build From Source Windows: Installer, Chocolatey NuGet
- 10. 10 Where Can IGet Elixir? Nerves: Elixir On Embedded Hardware
- 11. 11 How Do IGet Started With Elixir? REPL: iex Build Manager: mix Compiler: elixirc Editor Language Bindings: Vim Emacs Atom Sublime Text etc. etc. etc.
- 12. 12 What’s Mix? Elixir’s buildtool Leiningen:Clojure::Mix:Elixir
- 13. 13 How Do ICreate A New Elixir App? New app: mix new <appname> Run unit tests: mix test
- 14. 14 What Is Phoenix? Webframework Built with Elixir and Erlang
- 15. 15 How Do IGet Phoenix? 1.) Install Hex 2.) Install postgresql* 3.) Install node.js 4.) Install phoenix via mix mix archive.install https://github.com/phoenixframework/archives/raw/master/pho enix_new.ez *Postgresql is default—can use other DB’s.
- 16. 16 How Do IStart A New Phoenix App? mix phoenix.new <appname> cd appname mix ecto.create mix phoenix.server
- 17. 17 Summary/Review Elixir is alanguage based on the BEAM with high-scalability, fault-tolerance and other desirable properties for large scale applications We can get Elixir on a number of platforms Iex allows us to try out code and mix is a tool to allow us to easily build and test applications Phoenix is a web framework for Elixir.

Editor's Notes
- #3 Dispelling myths about FP What’s immutability and why does it matter? What’s a first class function? Built-in regular expressions Recursion vs. iteration Summary/review
- #4 Someone seems to have gotten the mistaken notion that adopting FP means dropping OO; nothing could be further from the truth. Let’s look at a few of the assumptions underlying that: 1.) Learning a new approach means abandoning an old approach. 2.) FP doesn’t have classes
