Phoenix web framework is awesome. Backed by the beauty and productive Elixir and performance and realibility of Erlang VM. This presentation is for Singapore Elixir Meetup in March 2016

Transcript

1. Riza Fahmi - ElixirDose.com - @rizafahmi22 - riza@ hacktiv8.com PRODUCTIVE. RELIABLE. FAST.
2. SPONSOR THANKS!
3. INTRODUCTION YOU’RE MY REGULATOR, MY COMPILER ▸ Scream when things go too fast / slow / are unclear ▸ Scream when cool things happen ▸ Help me when live coding, I’m suck at it. Find errors for me before the compiler do ▸ Similar to Phoenix channel, this is two way communication channel. Don’t let me do all the talking!
4. INTRODUCTION SLIDES ARE UP! https://slideshare.net
5. INTRODUCTION WHO AM I ▸ Was at CitizenLab, a Belgium-based early stage startup. As a CTO ▸ Now at Hacktiv8, a startup for dev bootcamp ▸ Run ElixirDose — an Elixir-focused blog since November 2013
6. INTRODUCTION WHAT WE’LL SEE ▸ The Awesomeness of Phoenix ▸ Build something with Phoenix ▸ Some live coding
7. SOME GLOSSARY Web Framework Programming Language Erlang Virtual Machine
8. WHAT IS PHOENIX
9. “Framework for building HTML5 apps, API backends and distributed systems to take on the modern web.” Chris McCord
10. HOW IS PHOENIX DIFFERENT?
11. PRODUCTIVITY PERFORMANCE VS
12. LET’S TALK PRODUCTIVITY
13. PRODUCTIVITY SHORT TERM ▸ Documentation / Guides / Generators ▸ Eliminates trivial choices
14. PRODUCTIVITY LONG TERM ▸ Maintainability ▸ Tried and true architecture patterns ▸ Let it crash mentality
15. “IF I HAVE TO BUILD SKYNET, KILLER ARTIFICIAL INTELLIGENT FROM TERMINATOR MOVIES, I WOULD USE ERLANG AND ERLANG VM. MOSTLY BECAUSE IT’S UNKILLABLE AND KEEP COMING BACK!” Simon St.Laurent from MostlyErlang Podcast
16. MORE FEATURES PLEASE…
17. FEATURES STATIC BUILD TOOLS WITH ES6 AS DEFAULT Ultra fast HTML5 build tools Compiles/lints your scripts and styles Concatenates your scripts and styles Minifies it Watches for file changes
18. FEATURES PRETTY AND HELPFUL ERROR PAGES
19. FEATURES CHANNELS ▸ The main reason why Phoenix exists in the first place ▸ It’s websocket with steroid ▸ Cross-platform, cross-languages ▸ For creating modern, real-time apps ▸ Beyond HTML
20. FEATURES MORE… ▸ Form builder ▸ Live reloading ▸ MCV with twist ▸ much more…
21. LET’S TALK PERFORMANCE NOW
23. PERFORMANCE VIEWS & TEMPLATES ▸ Precompiled and pretty fast! ▸ Views render templates ▸ It’s beyond HTML
24. PERFORMANCE WHAT ABOUT SOME BENCHMARK Frameworks Throughput (req/s) Latency (ms) Plug (Elixir) 54,948.14 3.83 Gin (Go) 51,483.20 1.94 Phoenix (Elixir) 43,063.45 2.82 Express Cluster (Nodejs) 27,669.46 3.73 Martini (Go) 14,798.46 6.81 Express (Nodejs) 9,965.56 10.07 Sinatra (Ruby) 9,182.86 6.55 Rails (Ruby) 3,274.81 17.25 https://github.com/mroth/phoenix-showdown
25. PERFORMANCE ROBUST CONCURRENCY MODEL ▸ “processes” is extremely lightweight units of concurrency ▸ Garbage collection is per process, no global pauses
26. “ WE DO NOT HAVE ONE WEB-SERVER HANDLING 2 MILLIONS SESSIONS. WE HAVE 2 MILLION WEBSERVERS HANDLING ONE SESSION EACH.” Joe Armstrong - Erlang Father http://goo.gl/DprVTC
27. LET’S BUILD SOMETHING
28. WHAT WE’LL BUILD ELIXIR VIDEO PORTAL ▸ CRUD app for collecting Elixir-related video ▸ Similar confreaks.tv or pyvideo.org
29. OFF ROAD… WE GO!
30. WANT MORE?
31. WANT MORE… READ SOME BOOKS
32. WANT MORE… WATCH AND LEARN
33. I’M DONE. THANKS FOR TUNING IN!
