In our days there a lot of javascript client and backend side frameworks. But for best understanding we should do practice, so I created repo to write there the same app "cash machine" using different frameworks.
The app has two sides back and client. On back there is api and on client there is ui.
It's something similar to TodoMVC

Mockup

React + Flux

Lots of people use React as the V in MVC. Since React makes no assumptions about the rest of your technology stack, it's easy to try it out on a small feature in an existing project.

Flux is the application architecture that Facebook uses for building client-side web applications. It complements React's composable view components by utilizing a unidirectional data flow.

Sails.js

Sails makes it easy to build custom, enterprise-grade Node.js apps. It is designed to emulate the familiar MVC pattern of frameworks like Ruby on Rails, but with support for the requirements of modern apps: data-driven APIs with a scalable, service-oriented architecture. It's especially good for building chat, realtime dashboards, or multiplayer games; but you can use it for any web application project - top to bottom.
