cmd shows that node is not an internal command. Solution: 1. Set the nodejs installation directory path into the system variable or user variable; 2. Restart the cmd window and enter "node -v" in the command window to view the version. Just number.
The operating environment of this article: windows7 system, nodejs10.16.2 version, Dell G3 computer.
What should I do if cmd shows that node is not an internal command?
cmd prompts 'node' is not an internal or external command, nor is it an operable program. Solution
Error condition:
When running the node -xxx command in the cmd window, the prompt 'node' is not an internal or external command, nor an operable program or batch file
Cause:
The environment variables are not configured correctly.
In fact, my situation is that it is not configured at all...The default location was changed during installation. This problem occurred when node -v was used, and environment variables need to be configured
Configuring environment variables :
(The installation path of my node.js is F:\Download\nodejs. When modifying the environment variables, just modify them according to your own installation directory)
windows system Here, you need to set the nodejs installation directory path into the system variable or user variable
1. Open the Control Panel->System and Security->System->Advanced System Settings->Environment Variables
If nodejs is in the user directory, both NODE_PATH and PATH are set in user variables
2. Find variables in "User Variables" or "System Variables" PATH and add node.js folder path as value. Usually it is C:\Program Files\nodejs;. If the variable does not exist, it is created.
Create variables: Take the variable I created as an example, create a new one in the user variable, enter the variable name - NODE_PATH, enter the value - F:\Download\nodejs, if there is no PATH variable in the user variable, create a new one PATH variable, the value is %NODE_PATH%, if there is one, just add the value
3.win R: Restart the cmd window (enter cmd after win R to open the command window), enter node -v in the command window Check the version number. If you can check the environment variable configuration is successful

HTML and React can be seamlessly integrated through JSX to build an efficient user interface. 1) Embed HTML elements using JSX, 2) Optimize rendering performance using virtual DOM, 3) Manage and render HTML structures through componentization. This integration method is not only intuitive, but also improves application performance.

React efficiently renders data through state and props, and handles user events through the synthesis event system. 1) Use useState to manage state, such as the counter example. 2) Event processing is implemented by adding functions in JSX, such as button clicks. 3) The key attribute is required to render the list, such as the TodoList component. 4) For form processing, useState and e.preventDefault(), such as Form components.

React interacts with the server through HTTP requests to obtain, send, update and delete data. 1) User operation triggers events, 2) Initiate HTTP requests, 3) Process server responses, 4) Update component status and re-render.

React is a JavaScript library for building user interfaces that improves efficiency through component development and virtual DOM. 1. Components and JSX: Use JSX syntax to define components to enhance code intuitiveness and quality. 2. Virtual DOM and Rendering: Optimize rendering performance through virtual DOM and diff algorithms. 3. State management and Hooks: Hooks such as useState and useEffect simplify state management and side effects handling. 4. Example of usage: From basic forms to advanced global state management, use the ContextAPI. 5. Common errors and debugging: Avoid improper state management and component update problems, and use ReactDevTools to debug. 6. Performance optimization and optimality

React can be embedded in HTML to enhance or completely rewrite traditional HTML pages. 1) The basic steps to using React include adding a root div in HTML and rendering the React component via ReactDOM.render(). 2) More advanced applications include using useState to manage state and implement complex UI interactions such as counters and to-do lists. 3) Optimization and best practices include code segmentation, lazy loading and using React.memo and useMemo to improve performance. Through these methods, developers can leverage the power of React to build dynamic and responsive user interfaces.

React is a JavaScript library for building modern front-end applications. 1. It uses componentized and virtual DOM to optimize performance. 2. Components use JSX to define, state and attributes to manage data. 3. Hooks simplify life cycle management. 4. Use ContextAPI to manage global status. 5. Common errors require debugging status updates and life cycles. 6. Optimization techniques include Memoization, code splitting and virtual scrolling.

React's future will focus on the ultimate in component development, performance optimization and deep integration with other technology stacks. 1) React will further simplify the creation and management of components and promote the ultimate in component development. 2) Performance optimization will become the focus, especially in large applications. 3) React will be deeply integrated with technologies such as GraphQL and TypeScript to improve the development experience.

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

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),
