How to use Vue.use() component through global method

This article mainly introduces vue’s custom global component and its use through the global method Vue.use(). It has certain reference value. Interested friends can refer to it

Introduction

Vue.use(plugin): Install the Vue.js plug-in. If the plugin is an object, the install method must be provided. If the plugin is a function, it will be used as the install method. The install method will be called as a parameter to Vue.

When the install method is called multiple times by the same plug-in, the plug-in will only be installed once.

Vue.js plug-ins should have a public method install. The first parameter of this method is the Vue constructor, and the second parameter is an optional options object:

MyPlugin.install = function (Vue, options) {
 // 1. 添加全局方法或属性
 Vue.myGlobalMethod = function () {
  // 逻辑...
 }
 // 2. 添加全局资源
 Vue.directive('my-directive', {
  bind (el, binding, vnode, oldVnode) {
   // 逻辑...
  }
  ...
 })
 // 3. 注入组件
 Vue.mixin({
  created: function () {
   // 逻辑...
  }
  ...
 })
 // 4. 添加实例方法
 Vue.prototype.$myMethod = function (methodOptions) {
  // 逻辑...
 }
}

Use the plug-in through the global method Vue.use():

// 调用 `MyPlugin.install(Vue)`
Vue.use(MyPlugin)

Also You can pass in an options object:

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

Vue.use will automatically prevent multiple registrations of the same plug-in, and the plug-in will only be registered once.

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 such as 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)

Example: Implement a children component

In main. How to use this component in js:

import childModule from './components/children'
Vue.use(childModule)

The directory structure of the component folder is as follows:

|-components
  |-children
    |-index.js 导出组件,并且install
    |-children.vue (定义自己的组件模板)

children.vue code is as follows:

import childrencomponent from './children.vue'
const childrenMo = {
  install:function(Vue){
    Vue.component('childModule',childrencomponent)
  }
}
export default childrenMo

In this way, a pass through vue is implemented .use calls a global component.

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.

JavaScript and the Web: Core Functionality and Use CasesJavaScript and the Web: Core Functionality and Use CasesApr 18, 2025 am 12:19 AM

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding the JavaScript Engine: Implementation DetailsUnderstanding the JavaScript Engine: Implementation DetailsApr 17, 2025 am 12:05 AM

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python vs. JavaScript: The Learning Curve and Ease of UsePython vs. JavaScript: The Learning Curve and Ease of UseApr 16, 2025 am 12:12 AM

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python vs. JavaScript: Community, Libraries, and ResourcesPython vs. JavaScript: Community, Libraries, and ResourcesApr 15, 2025 am 12:16 AM

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

From C/C   to JavaScript: How It All WorksFrom C/C to JavaScript: How It All WorksApr 14, 2025 am 12:05 AM

The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.

JavaScript Engines: Comparing ImplementationsJavaScript Engines: Comparing ImplementationsApr 13, 2025 am 12:05 AM

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.
