Node.js can do the backend
Node.js is an open source JavaScript runtime for developing efficient and scalable web applications. It is designed to provide a lightweight and efficient solution for providing fast and scalable backend services to web applications.
Node.js was first released by Ryan Dahl in 2009. It uses the Google V8 engine to execute JavaScript code and comes with a built-in HTTP server. Due to its efficiency and speed, Node.js has quickly become a popular web backend development platform in just a few years.
Although Node.js is a JavaScript runtime, it is not only intended for front-end development. It can also be used to develop back-end applications, including web servers, RESTful APIs, real-time applications, stream processing applications, and more. These applications all require efficient, scalable, and concurrent update capabilities, and the features provided by Node.js are well suited for these application scenarios.
Node.js provides numerous modules to facilitate building powerful backend applications. These include functions for operating file systems, handling HTTP requests and responses, handling Socket connections between clients and servers, accessing databases, and more. In addition, the NPM package manager provided by Node.js makes development easier by making it easy for developers to install, upgrade, and maintain dependencies.
Node.js achieves high concurrency and scalability by using an event-driven, non-blocking I/O model and a single-threaded event loop. This feature allows Node.js to easily handle thousands of simultaneous connections while reducing server resource usage and consumption. Some of the famous applications in Node.js include Netflix, LinkedIn, Uber, eBay, Walmart, PayPal, etc.
In short, Node.js is a very powerful back-end development tool with good scalability, efficiency and speed. It can handle back-end application scenarios well such as web servers, RESTful APIs, real-time applications, stream processing applications, etc. Therefore, Node.js is fully capable of back-end development tasks and is a technology worth learning, using, and exploring for developers.

React vs. Backend Frameworks: A ComparisonApr 13, 2025 am 12:06 AMReact is a front-end framework for building user interfaces; a back-end framework is used to build server-side applications. React provides componentized and efficient UI updates, and the backend framework provides a complete backend service solution. When choosing a technology stack, project requirements, team skills, and scalability should be considered.
HTML and React: The Relationship Between Markup and ComponentsApr 12, 2025 am 12:03 AMThe relationship between HTML and React is the core of front-end development, and they jointly build the user interface of modern web applications. 1) HTML defines the content structure and semantics, and React builds a dynamic interface through componentization. 2) React components use JSX syntax to embed HTML to achieve intelligent rendering. 3) Component life cycle manages HTML rendering and updates dynamically according to state and attributes. 4) Use components to optimize HTML structure and improve maintainability. 5) Performance optimization includes avoiding unnecessary rendering, using key attributes, and keeping the component single responsibility.
React and the Frontend: Building Interactive ExperiencesApr 11, 2025 am 12:02 AMReact is the preferred tool for building interactive front-end experiences. 1) React simplifies UI development through componentization and virtual DOM. 2) Components are divided into function components and class components. Function components are simpler and class components provide more life cycle methods. 3) The working principle of React relies on virtual DOM and reconciliation algorithm to improve performance. 4) State management uses useState or this.state, and life cycle methods such as componentDidMount are used for specific logic. 5) Basic usage includes creating components and managing state, and advanced usage involves custom hooks and performance optimization. 6) Common errors include improper status updates and performance issues, debugging skills include using ReactDevTools and Excellent
React and the Frontend Stack: The Tools and TechnologiesApr 10, 2025 am 09:34 AMReact is a JavaScript library for building user interfaces, with its core components and state management. 1) Simplify UI development through componentization and state management. 2) The working principle includes reconciliation and rendering, and optimization can be implemented through React.memo and useMemo. 3) The basic usage is to create and render components, and the advanced usage includes using Hooks and ContextAPI. 4) Common errors such as improper status update, you can use ReactDevTools to debug. 5) Performance optimization includes using React.memo, virtualization lists and CodeSplitting, and keeping code readable and maintainable is best practice.
React's Role in HTML: Enhancing User ExperienceApr 09, 2025 am 12:11 AMReact combines JSX and HTML to improve user experience. 1) JSX embeds HTML to make development more intuitive. 2) The virtual DOM mechanism optimizes performance and reduces DOM operations. 3) Component-based management UI to improve maintainability. 4) State management and event processing enhance interactivity.
React Components: Creating Reusable Elements in HTMLApr 08, 2025 pm 05:53 PMReact components can be defined by functions or classes, encapsulating UI logic and accepting input data through props. 1) Define components: Use functions or classes to return React elements. 2) Rendering component: React calls render method or executes function component. 3) Multiplexing components: pass data through props to build a complex UI. The lifecycle approach of components allows logic to be executed at different stages, improving development efficiency and code maintainability.
React Strict Mode PurposeApr 02, 2025 pm 05:51 PMReact Strict Mode is a development tool that highlights potential issues in React applications by activating additional checks and warnings. It helps identify legacy code, unsafe lifecycles, and side effects, encouraging modern React practices.
React Fragments UsageApr 02, 2025 pm 05:50 PMReact Fragments allow grouping children without extra DOM nodes, enhancing structure, performance, and accessibility. They support keys for efficient list rendering.

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),
DVWA
Damn Vulnerable Web App (DVWA) is a PHP/MySQL web application that is very vulnerable. Its main goals are to be an aid for security professionals to test their skills and tools in a legal environment, to help web developers better understand the process of securing web applications, and to help teachers/students teach/learn in a classroom environment Web application security. The goal of DVWA is to practice some of the most common web vulnerabilities through a simple and straightforward interface, with varying degrees of difficulty. Please note that this software
