What is a state in Vuex?

To help with that, Vuex allows us to divide our store into modules . Each module can contain its own state, mutations, actions, getters, and even nested modules – it’s fractal all the way down: const moduleA = { state: () => ({ … }), mutations: { … }, actions: { …

Create the Vuex store This file can be put anywhere. It’s generally suggested to put it in the src/store/store. js file , so we’ll do that.

At the center of every Vuex application is the store. A “store” is basically a container that holds your application state. There are two things that make a Vuex store different from a plain global object: Vuex stores are reactive.

Vuex allows us to define “getters” in the store. You can think of them as computed properties for stores . WARNING. As of Vue 3.0, the getter’s result is not cached as the computed property does. This is a known issue that requires Vue 3.1 to be released.

State is a crucial part of Vue applications and other frontend frameworks as it is responsible for how data is passed among components and views . The managing of state tends to become complex as an application grows larger.10 Mar 2021

So after understanding the project, if a particular state is consumed by multiple components then and then you have to use Vuex.

Vuex is a state management library for Vue. js, that is based on the Flux pattern. In the above code, the increment function is a dispatcher that updates the value of the count property . When we have full control over every state change, we can easily track all of them and make our app much easier to debug.
