How to use vue.mixin: 1. Multiple components can share data and methods. After being introduced into the component using mixin, the methods and properties in the mixin are also incorporated into the component, and can be directly Use; 2. Both hook functions will be called, and the hook in the mixin will be executed first.

Usage of vue.mixin Method:
Vue provides a mixing mechanism - mixins, to achieve more efficient reuse of component content. At first I thought there was no difference between this and components. . Later I found out it was wrong. Let's take a look at the difference between mixins and imported components under normal circumstances.
After the component is referenced, it is equivalent to opening up a separate space in the parent component to perform corresponding operations based on the values from the parent component props. In essence, the two are distinct and relatively independent.
And mixins, after introducing the component, merge the internal content of the component such as data and other methods, method and other attributes with the corresponding content of the parent component. It is equivalent to that after the introduction, various property methods of the parent component have been expanded.
Simple component reference:
Parent component sub-component>>> Parent component sub-component
Mixins:
Parent component Child component>>> new parent component
Function: Multiple components can share data and methods. After being introduced in the component using mixin, the methods in the mixin are the same as those in the mixin. The properties are then incorporated into the component and can be used directly. Both hook functions will be called, with the hook in the mixin executing first.
Let me introduce you to the usage of vue mixin. The specific introduction is as follows:
1. Define a js file (mixin.js)
export default {
data() {
return {
name: 'mixin'
}
},
created() {
console.log('mixin...', this.name);
},
mounted() {},
methods: {}
}2. In the vue file Free learning recommendations for using mixin
import mixin from '@/mixin'; // 引入mixin文件
export default {
mixins: [mixin]

Netflix's Frontend: Examples and Applications of React (or Vue)Apr 16, 2025 am 12:08 AMNetflix uses React as its front-end framework. 1) React's componentized development model and strong ecosystem are the main reasons why Netflix chose it. 2) Through componentization, Netflix splits complex interfaces into manageable chunks such as video players, recommendation lists and user comments. 3) React's virtual DOM and component life cycle optimizes rendering efficiency and user interaction management.
The Frontend Landscape: How Netflix Approached its ChoicesApr 15, 2025 am 12:13 AMNetflix's choice in front-end technology mainly focuses on three aspects: performance optimization, scalability and user experience. 1. Performance optimization: Netflix chose React as the main framework and developed tools such as SpeedCurve and Boomerang to monitor and optimize the user experience. 2. Scalability: They adopt a micro front-end architecture, splitting applications into independent modules, improving development efficiency and system scalability. 3. User experience: Netflix uses the Material-UI component library to continuously optimize the interface through A/B testing and user feedback to ensure consistency and aesthetics.

The Choice of Frameworks: What Drives Netflix's Decisions?Apr 13, 2025 am 12:05 AMNetflix mainly considers performance, scalability, development efficiency, ecosystem, technical debt and maintenance costs in framework selection. 1. Performance and scalability: Java and SpringBoot are selected to efficiently process massive data and high concurrent requests. 2. Development efficiency and ecosystem: Use React to improve front-end development efficiency and utilize its rich ecosystem. 3. Technical debt and maintenance costs: Choose Node.js to build microservices to reduce maintenance costs and technical debt.
React, Vue, and the Future of Netflix's FrontendApr 12, 2025 am 12:12 AMNetflix mainly uses React as the front-end framework, supplemented by Vue for specific functions. 1) React's componentization and virtual DOM improve the performance and development efficiency of Netflix applications. 2) Vue is used in Netflix's internal tools and small projects, and its flexibility and ease of use are key.
Vue.js in the Frontend: Real-World Applications and ExamplesApr 11, 2025 am 12:12 AMVue.js is a progressive JavaScript framework suitable for building complex user interfaces. 1) Its core concepts include responsive data, componentization and virtual DOM. 2) In practical applications, it can be demonstrated by building Todo applications and integrating VueRouter. 3) When debugging, it is recommended to use VueDevtools and console.log. 4) Performance optimization can be achieved through v-if/v-show, list rendering optimization, asynchronous loading of components, etc.
Vue.js and React: Understanding the Key DifferencesApr 10, 2025 am 09:26 AMVue.js is suitable for small to medium-sized projects, while React is more suitable for large and complex applications. 1. Vue.js' responsive system automatically updates the DOM through dependency tracking, making it easy to manage data changes. 2.React adopts a one-way data flow, and data flows from the parent component to the child component, providing a clear data flow and an easy-to-debug structure.
Vue.js vs. React: Project-Specific ConsiderationsApr 09, 2025 am 12:01 AMVue.js is suitable for small and medium-sized projects and fast iterations, while React is suitable for large and complex applications. 1) Vue.js is easy to use and is suitable for situations where the team is insufficient or the project scale is small. 2) React has a richer ecosystem and is suitable for projects with high performance and complex functional needs.

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),
