Below I will share with you a detailed explanation of the configuration method of using sass based on css preloading in vue. It has a good reference value and I hope it will be helpful to everyone.
1. Install the sass dependency package
npm install --save-dev sass-loader
//sass-loader依赖于node-sass npm install --save-dev node-sass
2. Add configuration in the rules of webpack.base.conf.js under the build folder, as shown in the red part below
{ test: /\.sass$/, loaders: ['style', 'css', 'sass'] }
<span style="color:#454545;">// module用来解析不同的模块 module: { rules: [ ...(config.dev.useEslint ? [createLintingRule()] : []), { test: /\.vue$/, // 也就是说,对.js和.vue文件在编译之前进行检测,检查有没有语法错误'eslint-loader' // enforce: 'pre'选项可以确保,eslint插件能够在编译之前检测,如果不添加此项,就要把这个配置项放到末尾,确保第一个执行 // 对vue文件使用vue-loader,该loader是vue单文件组件的实现核心,专门用来解析.vue文件的 loader: 'vue-loader', // 将vueLoaderConfig当做参数传递给vue-loader,就可以解析文件中的css相关文件 options: vueLoaderConfig }, { test: /\.js$/, // 对js文件使用babel-loader转码,该插件是用来解析es6等代码 loader: 'babel-loader', // 指明src和test目录下的js文件要使用该loader include: [resolve('src'), resolve('test')] }, { test: /\.(png|jpe?g|gif|svg)(\?.*)?$/, // 对图片相关的文件使用 url-loader 插件,这个插件的作用是将一个足够小的文件生成一个64位的DataURL // 可能有些老铁还不知道 DataURL 是啥,当一个图片足够小,为了避免单独请求可以把图片的二进制代码变成64位的 // DataURL,使用src加载,也就是把图片当成一串代码,避免请求,神不神奇?? loader: 'url-loader', options: { // 限制 10000 个字节一下的图片才使用DataURL limit: 10000, name: utils.assetsPath('img/[name].[hash:7].[ext]') } }, { test: /\.(mp4|webm|ogg|mp3|wav|flac|aac)(\?.*)?$/, // 字体文件处理,和上面一样 loader: 'url-loader', options: { limit: 10000, name: utils.assetsPath('media/[name].[hash:7].[ext]') } }, { test: /\.(woff2?|eot|ttf|otf)(\?.*)?$/, loader: 'url-loader', options: { limit: 10000, name: utils.assetsPath('fonts/[name].[hash:7].[ext]') } }, </span><span style="color:#ff0000;">{ test: /\.sass$/, loaders: ['style', 'css', 'sass'] }</span><span style="color:#454545;"> ] },</span>
##3. Modify the style lang="scss" in the template; for example, the template is red Tag
<style lang="scss">

商家 <style lang="scss"> #indexContent { .tab{ display: flex; width:100%; height: 40px; line-height: 40px; .tab-item { flex: 1; text-align: center; a{ display:block; } } } }
##4.npm run dev
5. Effect
The above is what I compiled for you, I hope it will be helpful to everyone in the future.

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.

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 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 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 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.

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.

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.

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),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
