Any developers familiar with React.js and Flux?

It’s not about the scale (if you mean the number of CRUD operations) but about how many different CRUD dialogs you have. For a mail client I guess is a very limited number (and Instagram probably the same). My point is, if the number of these dialogs is small, moving from a JS library/framework to another is not so much work.

To be honest and for what I’ve read, I don’t like neither Angular or React. Angular because the custom HTML tags, and React because the generation of HTML from within JS.
