Stent is combining the ideas of Redux with the concept of state machines.
A few words about state machines
State machine is a mathematical model of computation. It's an abstract concept where the machine may have different states but at a given time fulfills only one of them. It accepts input and based on that (plus its current state) transitions to another state. Isn't it familiar? Yes, it sounds like a front-end application. That's why this model/concept applies nicely to UI development.
Disclaimer: there are different types of state machines. I think the one that makes sense for front-end development is Mealy state machine.
Installation
The library is available as a npm module so npm install stent
or yarn add stent
will do the job. There's also a standalone version here (only core functionalities) which you can directly add to your page.
