What are Vuex plugins and how do I use them?

Vuex plugins are functions that allow you to extend Vuex's capabilities. They can be used to add custom behavior to the store.

Can you give me an example of a simple Vuex plugin?

Sure! A simple plugin could log every mutation to the console. You can create it like this:

const logger = store => {
  store.subscribe((mutation, state) => {
    console.log('Mutation:', mutation);
  });
};

Then, you can use it when creating the store.

How do I register a plugin when creating the Vuex store?

You can register a plugin by passing it as an array to the plugins option when creating the store:

import Vue from 'vue';
import Vuex from 'vuex';

Vue.use(Vuex);

const store = new Vuex.Store({
  // your state, mutations, etc.
  plugins: [logger]
});

Are there any built-in Vuex plugins?

Vuex itself doesn't come with built-in plugins, but you can find community plugins for various functionalities, like persistence.
