What are vue plug-ins?

Vue.js plug-ins are tools developed with Vue.js. We only need to use very little code when calling to achieve good results. It facilitates later maintenance and improves development efficiency.

Vue.js plugins are a powerful and easy way to add global functionality to your application.

Plug-ins are usually used to add global functionality to Vue. There are no strict restrictions on the functional scope of plug-ins - generally there are the following types:

• Add global methods or properties. For example: vue-custom-element

• Add global resources: directives/filters/transitions, etc. For example, vue-touch

• adds some component options through global mixing. For example, vue-router

• adds Vue instance methods by adding them to Vue.prototype.

• A library that provides its own API while providing one or more of the functions mentioned above. For example, vue-router

Use plug-ins

Use plug-ins through the global method Vue.use(). It needs to be completed before you call new Vue() to start the application:

// 调用 `MyPlugin.install(Vue)`
Vue.use(MyPlugin)
new Vue({
  // ...组件选项
})

You can also pass in an optional options object:

Vue.use(MyPlugin, { someOption: true })

Vue.use will automatically prevent multiple registrations of the same plugin. , then the plug-in will only be registered once even if called multiple times.

Some plug-ins officially provided by Vue.js (such as vue-router) will automatically call Vue.use() when detecting that Vue is an accessible global variable. However, in a module environment like CommonJS, you should always call Vue.use() explicitly:

// 用 Browserify 或 webpack 提供的 CommonJS 模块环境时
var Vue = require('vue')
var VueRouter = require('vue-router')
// 不要忘了调用此方法
Vue.use(VueRouter)
