Debian is a stable and secure Linux distribution widely used in server and desktop environments. Nodejs is a popular JavaScript runtime environment for building efficient web applications. In this article, we will discuss how to install Nodejs using Debian system.
Step 1: Update your system
It is a good idea to update your Debian system before installing any new packages. Execute the following command in the terminal window:
sudo apt-get update sudo apt-get upgrade
Step 2: Install Nodejs
In Debian, Nodejs can be installed in various ways. In this tutorial, we will use the NodeSource package library. This package repository is great for troubleshooting issues with older versions of Nodejs in the official Debian repository.
To install NodeSource, you need to enter the following command in the terminal:
curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
This will automatically set up the Nodejs APT repository. To install Node.js from the repository, execute the following command:
sudo apt-get install -y nodejs
This command will download and install Nodejs and all its dependencies.
Step 3: Check whether Nodejs is installed successfully
After the installation is completed, you can use the following command to check whether Nodejs has been installed successfully:
node -v
If you are in the terminal window If you see output similar to the following, Nodejs has been successfully installed:
v14.15.4
Step 4: Install npm
npm is the package manager for Node.js, used to manage JavaScript applications Various packages and dependencies used in the program. After Nodejs is installed, npm should also be installed. You can check whether npm installation is successful by executing the following command:
npm -v
If npm is not installed automatically, you can install it manually by executing the following command:
sudo apt-get install -y npm
Step 5: Upgrade npm
If you already have npm installed, make sure to upgrade to the latest version. Just execute the following command:
sudo npm install npm@latest -g
Step 6: Install global npm modules
After installing and using Nodejs and npm, you can install global npm modules, which are useful for building and deploying applications The program is very useful. Execute the following command in a terminal window to install global modules:
sudo npm install -g express pm2
This will download and install a number of global npm modules such as express and pm2.
Conclusion
Now you know how to install Nodejs on Debian and set up npm. You can start building and deploying web applications using Nodejs and npm. If you encounter problems or have any questions, please refer to the official Nodejs documentation or post on the community forum for help.

React 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 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 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 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 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 allow grouping children without extra DOM nodes, enhancing structure, performance, and accessibility. They support keys for efficient list rendering.

The article discusses React's reconciliation process, detailing how it efficiently updates the DOM. Key steps include triggering reconciliation, creating a Virtual DOM, using a diffing algorithm, and applying minimal DOM updates. It also covers perfo

The article discusses the Virtual DOM, a key concept in web development that enhances performance by minimizing direct DOM manipulation and optimizing updates.
