Managing Global State with a Plugin
You need to create a custom Vue plugin, which allows you to access and modify the centralized store or state object of any component in an application, so that you can manage Global State with this plugin. In order to ensure that changes to the state automatically trigger updates for all components using that state, the plugin uses Vue’s reactivity system.
Syntax:
import { ref } from 'vue';
const count = ref(0);
const increment = () => {
count.value++;
};
export default {
count,
increment,
};
Example:
myPlugin.js
Javascript
import { ref } from 'vue' ; const count = ref(0); const increment = () => { count.value++; }; export default { count, increment, }; |
main.js
Javascript
import { createApp } from 'vue' ; import App from './App.vue' ; import myPlugin from '../src/plugins/myPlugin' ; const app = createApp(App); app.use(myPlugin); app.mount( '#app' ); |
App.vue
Javascript
<template> <div> <h1>w3wiki</h1> <h2 style= "color: green" > Plugins in Vue.js </h2> <button @click= "increment" > Increment </button> <p>Count: {{ count }}</p> </div> </template> <script setup> // Update the path to the myPlugin // file accordingly import myPlugin from '../src/plugins/myPlugin' ; const { count, increment } = myPlugin; </script> |
