Let’s talk about how to uninstall the vue plug-in

During the Vue project development process, we often use Vue plug-ins to extend the functionality of the application. Sometimes we may need to uninstall a plug-in. This article will introduce how to uninstall a plug-in in Vue.

1. Uninstall global plug-ins

In a Vue application, you can use Vue.use() to install plug-ins globally. If you want to uninstall a global plug-in, you can use Vue-destroy, the reverse operation of Vue.use().

1.1 Vue-destroy

Vue-destroy is an officially provided small JavaScript library for uninstalling VueJS plug-ins. It can be used to destroy plugins registered in Vue.use(). Using this library is simple, just install vue-destroy and add the plugin to your Vue instance.

Installation:

npm install vue-destroy --save

Usage:

import destroy from 'vue-destroy';
import Vue from 'vue';

Vue.use(destroy);

When uninstalling a plug-in, you only need to call the $destroy method of the plug-in instance, as shown below:

import Vue from 'vue';

Vue.$destroy();

1.2 Uninstalling plug-ins in Vue.js 3.0

In VueJS 3.0, the return value of the Vue.use() method is a destructible object, which can be destructed using the unuse() method. uninstall. As shown below:

import { createApp } from 'vue';
import MyPlugin from './plugins/my-plugin.js';

const app = createApp(...);
const pluginInstance = app.use(MyPlugin);

// Uninstall plugin
pluginInstance.unuse();

2. Uninstall partial plug-ins

In the Vue application, you can use the following method to install partial plug-ins:

2.1 Method 1

Partial plug-ins can be implemented by extending the Vue component, as shown below:

import MyPlugin from './plugins/my-plugin.js';

export default {
  name: 'MyComponent',
  mounted() {
    MyPlugin.install(this.$root);
  }
}

Uninstalling the local plug-in requires calling the MyPlugin.uninstall() method in the destroyed hook of the component, as shown below:

import MyPlugin from './plugins/my-plugin.js';

export default {
  name: 'MyComponent',
  mounted() {
    MyPlugin.install(this.$root);
  },
  destroyed() {
    MyPlugin.uninstall();
  }
}

2.2 Method 2

Another way to install and uninstall plug-ins in Vue is to add the plug-in to the Vue prototype. Here is an example:

import MyPlugin from './plugins/my-plugin.js';
import Vue from 'vue';
Vue.prototype.$myPlugin = MyPlugin;

In the component, we can access the plugin through $myPlugin:

export default {
  name: 'MyComponent',
  mounted() {
    this.$myPlugin.install(this.$root);
  },
  destroyed() {
    this.$myPlugin.uninstall();
  }
}

Summary

Uninstalling the Vue plugin is not like So easy to install. It covers many concepts like global and local plugins and VueJS version changes. In Vue.js 3.0, the return value of the Vue.use() method is a destructible object, which can be unloaded using the unuse() method. In Vue.js 2.0, global plugins can be uninstalled using the Vue-destroy library. Uninstalling a partial plug-in may require calling the plug-in's uninstall() method in the component's destroyed hook. However, these are very simple tasks and just need to be done the right way.
