Vuex is a state management pattern + library for Vue.js applications. It serves as a centralized store for all the components in an application, with rules ensuring that the state can only be mutated in a predictable fashion. It also integrates with Vue's official [devtools extension](https://github.com/vuejs/vue-devtools) to provide advanced features such as zero-config time-travel debugging and state snapshot export / import.

Learn more about Vuex at "[What is Vuex?](https://vuex.vuejs.org/)", or get started by looking into [full documentation](http://vuex.vuejs.org/).
