This time I will show you how to register the global components of Vue with use, and what are the precautions for registering Vue global components with use. The following is a practical case, let's take a look.

The components and instructions in Vue are divided into local components, local instructions and global components and global instructions. When registering a certain number of global instructions and global components, the method in the official document seems a bit unclear.

Global component

Introduced in the Vue official documentation is to use Vue.component(tagName, options) to create a global component. However, this method is written in the same file as the root instance. If you want to register multiple global components at the same time, it will make the root instance file too heavy, so use Vue.use() to "

Install" Global components appear lighter.

Method:

1. Create a new plugins folder

2. Create a global component in the folder File components.

js

3.Introduce all global components to be registered in the components.js file

4.Introduce components in the app.js root instance file .js

Take the eg component as an example:

components.js:

import eg from '../components/eg.vue';
export default (Vue)=>{
 Vue.component("Eg",eg);
}

app.js:

import components from './plugins/components.js';
Vue.use(components);
After the above writing, the global component Eg is registered.

When multiple global components need to be registered, it is more refreshing to use this method!

Global directive

For the registration of global directives, the method given in the official documentation is to use Vue.

directive (), the location is also under the root instance file, so here comes the problem. If there are multiple global instructions, coupled with multiple global components, the app.js file will become extremely bloated.

Therefore, similar to the above method of registering global components, Vue.use() is also used to "install" global instructions.

Method:

1. Create a new plugins folder

2. Create a global component in the folder File directives.js

3. Introduce all global directives to be registered in the directives.js file

4. In the app.js root instance file, introduce directives.js

Take the v-focus directive as an example:

directives.js:

export default (Vue)=>{
 Vue.directive("focus",{
  inserted:function(el){
   el.focus();
  }
 })
}

app.js

import directives from "./plugins/directives.js"
Vue.use(directives);
This way The global directive is registered.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
