This document provides tips for being prepared for the rise of Node.js and APIs for mobile applications. It discusses how Node.js is well-suited for building APIs and real-time applications due to its asynchronous and event-driven nature. It also offers recommendations for tools to use for Node.js development, such as unit testing with Mocha, package management with npm, process management with PM2, and deployment with Ansible.

12. NOW ITS 2010’S
EVERYBODY NEEDS MOBILE APP

17. THAT’S ALL
THANK YOU!

18. BUT, IF…

19. API

21. NO API
NO PUBLIC API
NO MOBILE PUBLIC API
ARE YOU PREPARED?

22. WHAT MAKES API MOBILE?

23. LOW BANDWIDTH
HIGH LATENCY
NETWORK CONDITIONS VARY
Mobile device is

24. SEND ONLY WHAT IS NEEDED

25. SCREEN-ORIENTED
NO CRUD-OVER-AIR

26. AVOID MULTIPLE ROUNDTRIPS
CAUSED BY LAZY DESIGN
EVERY REQUEST COUNTS

27. VERSIONING
OR KEEP STABLE CONTRACT

28. SECURITY
AUTHENTICATION
TRANSIT
API ABUSE

29. ANALYTICS

30. Our approach

31. PLATFORM APIs

35. PUSH NOTIFICATIONS GATEWAY
Mobile features

36. ENTER

37. EVENT-DRIVEN
NETWORK PROGRAMS
JAVASCRIPT
Node.js is

38. V8

39. WHY NODE.JS?

40. DB
SERVICE
REQUEST
REQUEST
REQUEST
REQUEST
TRADITIONAL WAY

41. WHAT WEB SERVERS DO MOST THE TIME?
THEY WAIT

42. WHAT THREADS DO MOST THE TIME?
THEY SUCK

43. EVENT
LOOP
I/O
REGISTER CALLBACK
OPERATION COMPLETE

44. LESS THREADS
LESS MEMORY OVERHEAD
LESS COMPUTATION (!)

45. NODE.JS SURVIVAL KIT

46. Editors
