3. Performance!
Before: 12s to see content
After: 2s to see content

4. Let’s Re-word That

5. Performance!
Well Meaning But Short Sighted Code:
Clean Modular Code:

6. Quick Notes on
Trulia’s Mobile Site
Respectable Traffic:
6+ million weekly visitors on our mobile website
Minimal Hardware:
2 x 24 core node servers with 24 instances of Rendr each (running cool)
Each instance is ~140mb of ram (About 3.5gb total)

7. Let’s Go Check It Out.

8. So, looking back,
how’d it go?
Specifically, with Rendr?

9. Fantastic!
Got a prototype up in week
AirBNB is a respectable engineering brand
Would rather augment a library than fight a framework
Rendr offers respectable access points to extend and override
All good metrics are way up, bad metrics are way down.

10. Well, There Was
Some Pain
Documentation is lacking,
It works well…once you know where the dragons are
To really tune the experience you’ll need to override non extendable internals
Rendr is a young library
Open Source Projects are not perfect

11. The Big Question:
Would You Use Rendr
Again?

12. Yes, But…
Confidential

13. Ok. So Should I Use
Rendr?

14. It Depends.
These days there are a lot of other options:
Easel: Artsy’s Backbone/Isomorphic Library
React: 1.0 will be Isomorphic (still meh on mobile events)
Meteor: A big framework for Isomorphic Javascript
LazoJS: Walmart’s smaller framework for Isomorphic Javascript
Confidential

15. Ok. So Should I Go
Isomorphic?

16. Want a Single Page
App Experience?
Yes!!
!

Otherwise, it depends.
