How to install Node.js on Apple computers
Node.js is a JavaScript running environment based on the Chrome V8 engine, which allows JavaScript to run on the server side. Here we take Apple computers as an example to introduce how to install Node.js.
Step one: Download and install Node.js
- Open the Node.js official website, https://nodejs.org/en/download/, and download the macOS version of the package.
- Double-click the downloaded .pkg file to start the installation wizard.
- Follow the prompts to install step by step.
Step 2: Check whether Node.js is installed successfully
- Open the terminal (Terminal) and enter the following command in the terminal:
node -v
- If the terminal outputs the version number of Node.js, the installation is successful, as shown below:
v10.16.0
Step 3: Use NPM to manage Node.js packages
NPM (Node Package Manager) is a Node.js package management tool that allows you to install, upgrade, and uninstall Node.js packages very conveniently.
- Enter the following command in the terminal to install a global package:
npm install -g nodemon
- In any folder, open the terminal and enter the following command to create a new one package.json file:
npm init
- Set according to the prompts. After completion, a package.json file will be generated to facilitate project management.
Step 4: Use Node.js for development
After installing Node.js, you can use Node.js for development. Enter the project directory in the terminal and use the following command to run the project:
node app.js
The above are the steps for installing and using Node.js on Apple computers. I hope it can be helpful to everyone.

HTML and React's Integration: A Practical GuideApr 21, 2025 am 12:16 AMHTML 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 and HTML: Rendering Data and Handling EventsApr 20, 2025 am 12:21 AMReact 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.
The Backend Connection: How React Interacts with ServersApr 20, 2025 am 12:19 AMReact 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: Focusing on the User Interface (Frontend)Apr 20, 2025 am 12:18 AMReact 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 in the HTML: Building Interactive User InterfacesApr 20, 2025 am 12:05 AMReact 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: The Foundation for Modern Frontend DevelopmentApr 19, 2025 am 12:23 AMReact 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.
The Future of React: Trends and Innovations in Web DevelopmentApr 19, 2025 am 12:22 AMReact'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.

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),
