Over the past year or so, the web team here at Vixlet has embarked on an exciting journey of moving our entire web application to a React + Redux architecture. It has been a growing opportunity for our entire team and throughout this process, we have some challenges along the way.

Disclaimer: The practices and methods described below have been found applicable to the performance needs of our specific application.

No, I’m the kind of person who typically spends my lunch break pretty much the same way I spend the rest of my time, hunched over in front of my MacBook either working through my lunch break or mindlessly surfing the net until I’m in a zoned-out cyber-haze that’s difficult to shake off. I’ve come to realize that neither of those two options is particularly good for me. And though the best thing for me to do would probably involve me getting off my computer and going for a walk, realistically that probably won’t happen. …
