🗃️ Centralized State Management for Vue.js.
This is the official Vuex 4 release.
The focus for Vuex 4 is compatibility. Vuex 4 supports Vue 3, and it provides the exact same API as Vuex 3, so users can reuse their existing Vuex code with Vue 3.
There are a few breaking changes described in a later section, so please check them out.
You can find basic usage with both Option and Composition API in the example directory.
It's still released under next tag in NPM package as same as Vue 3. We're planning to remove next tag once Vue 3 is ready to remove it.
There have been a lot of contribution to make Vuex 4 stable. Thank you all for your very much appreciated help. It wouldn't have been possible without this wonderful Vue community!

To align with the new Vue 3 initialization process, the installation process of Vuex has changed.
To create a new store instance, users are now encouraged to use the newly introduced createStore function.
import { createStore } from 'vuex'
export const store = createStore({
state() {
return {
count: 1
}
}
})
Whilst this is not technically a breaking change, you may still use the
new Store(...)syntax, we recommend this approach to align with Vue 3 and Vue Router 4.
To install Vuex to a Vue instance, pass the store instance instead of Vuex.
import { createApp } from 'vue'
import { store } from './store'
import App from './App.vue'
const app = createApp(App)
app.use(store)
app.mount('#app')
The following bundles are generated to align with Vue 3 bundles:
vuex.global(.prod).js
<script src="..."> in the browser. Exposes the Vuex global.<script src="...">..prod.js files for production.vuex.esm-browser(.prod).js
<script type="module">.vuex.esm-bundler.js
webpack, rollup and parcel.process.env.NODE_ENV guards (must be replaced by bundler).vuex.cjs.js
require().ComponentCustomPropertiesVuex 4 removes its global typings for this.$store within Vue Component to solve issue #994. When used with TypeScript, you must declare your own module augmentation.
Place the following code in your project to allow this.$store to be typed correctly:
// vuex-shim.d.ts
import { ComponentCustomProperties } from 'vue'
import { Store } from 'vuex'
declare module '@vue/runtime-core' {
// Declare your own store states.
interface State {
count: number
}
interface ComponentCustomProperties {
$store: Store<State>
}
}
createLogger function is exported from the core moduleIn Vuex 3, createLogger function was exported from vuex/dist/logger but it's now included in the core package. You should import the function directly from vuex package.
import { createLogger } from 'vuex'
