I love YNAB. It's a money management methodlogy that is implemented through a web app. It has been a game changer for me and has helped me take financial ownership over the past 5 years.
This will be my attempt to re-write the front-end as a component driven, mobile first web app...all in React! (Not guts, just front-end. Back end stuff is just not my currency.)
It's one of my goals to work with them––in the mean time, I'll do this. :)
Based on my react-es6-postcss-boilerplate.
I will explain better later, but basically fork this, npm install and then npm start.
