Vue3项目中如何使用Vuex?

npm install vuex@next --save
or
yarn add vuex@next --save

npm install es6-promise --save # NPM
yarn add es6-promise # Yarn

import 'es6-promise/auto'

import { createApp, reactive } from 'vue'
import { createStore } from 'vuex'
import App from './App.vue'
import './index.css'

const store = createStore({
	state() {
		return {
			count: 0
		}
	},
	mutations: {
		increment(state) {
			state.count++
		}
	}
})

const app = createApp(App)

app.use(store)
app.mount('#app')
