Node.js is a JavaScript running environment based on the Chrome V8 engine. It allows JavaScript to run on the server side, giving it many features such as non-blocking I/O, event-driven model, and single-threading. Node.js is widely used to build high-performance web applications and tools. In this article, I'll explain how to install Node.js so you can start using it.
Before installing Node.js, you need to know the operating system used on your computer and whether its processor is x86 or x64. You can find this information by opening the System Information page. If you are running a Windows operating system, you can press the Windows key R key, then enter "msinfo32" and press the Enter key to open the system information page.
One way to install Node.js is through the official installer. It works on Windows, Mac, and Linux and provides you with the latest versions of node and npm.
Please follow the steps below to perform this process:
- Visit the official website of Node.js, click on the "Downloads" menu, and select your operating system.
2. Select the current stable version. After selecting your operating system and CPU architecture, you may also want to select the correct versions of node and npm. There are x86 and x64 versions of the installer available. If you're not sure which version your computer has, check the operating system information.
3. Download the compiled binary and run it.
- Once the program runs, you will see an installation wizard interface.
- In the next few steps, you will be prompted to select the components to install and the target installation location. Please choose according to your actual needs.
- By default, the installer will add node to the PATH environment variable so that node commands can be used at any time. However, if you do not wish to do this, you can uncheck this option.
- Click the "Install" button to start the installation.
- Once the installation is complete, you can enter the "node -v" command in the terminal or command line to view the installed node version.
In addition to using the official installer, there are many other ways to install and manage Node.js. On Linux, you can install using a package manager such as apt-get, yum or pacman. On MacOS, you can use Homebrew to install and manage node. It can also be managed and installed using Node Version Manager (nvm) or Node Package Manager (npm).
Overall, installing Node.js is very simple. No matter which method you choose to use, you can install and start using it in just a few steps. Once you have it installed, you can try using Node.js to build web applications and tools that make them performant and scalable.
The above is the detailed content of nodejs installation installation mode. For more information, please follow other related articles on the PHP Chinese website!
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.
