What I need in every project is react for the UI, babel for modern JS and webpack. (I went through combinations of gulp, browserify, requirejs and brunch. Webpack finally solved the packaging-mess for me). Redux is something you can implement yourself easily, I never understood the need for a library there. The good idea of redux is to have a serialisable state which is changed through events. This gives you unidirectional data-flow and the ability to pause/restore your application. Complete immutability and funneling everything through functions on the other hand often just obscures readability, and, in case you are using immutablejs, gives you terrible performance. If I want to have purely functional programs I don't use Javascript, but Haskell or something. If I need time-travelling debugging, which I never found very useful when dealing with complex states, I'll implement it by copying my state using serialization.
