I had the pleasure of going to the BrazilJS 2013 conference last week. After 5 hours inside a car with my friends Munhoz and Ragonha, we got to see a nice sunrise, but that was the last time we saw the sun in Porto Alegre.
Even with the bad weather, BrazilJS was one of the best technology conferences I’ve ever attended. Outstanding organization, good infrastructure, amazing speakers. The only thing that comes to my mind that can be improved is the Internet connection, but many of the speakers made sure the the organizers ought to fix this next year, so I don’t need to stress this point.
I will post my impressions about the talks. More will follow on the coming days.
###Utilizando node.js para automação de build e deploy (Mauricio Wolff)
###Learning to fly - Twitter Flight and mixin (Angus Croll)
###Performance as a Twitter feature (Marcel Duran)
Continuing with the twitter personnel, Marcel spoke about how to deal with performance as a feature. Instead of only monitoring performance in production, he shows how to measure it in development time, and break builds if any degradation is detected. With this purpose in mind, some tools were showed, like the webpagetest. Marcel also created a wrapper for this project that can be installed through a npm package. The wrapper provides some command line tools, and can be easily used with a number of CI tools.
