To run Node.js, follow these steps:
- Install Node.js: Visit the official Node.js website (https://nodejs.org) and download the latest version of Node.js for your operating system. Choose the LTS (Long Term Support) version if you want a stable release. Follow the installation instructions provided for your specific operating system.
- Verify the installation: Once Node.js is installed, open your terminal or command prompt and type the following command to check if Node.js is properly installed:
Copy code
node -v
This command will display the installed version of Node.js. If you see the version number, it means Node.js is installed correctly.
3. Create a Node.js file: Use a text editor to create a new file with a .js extension. For example, you can create a file called app.js. This will be your Node.js application file where you write your code.
4. Write your Node.js code: Open the app.js file in your text editor and start writing your Node.js code. You can begin with a simple “Hello, World!” example:
javascriptCopy code
console.log("Hello, World!");
Feel free to explore more complex code examples and tutorials based on your requirements.
5. Run your Node.js file: Once you have written your Node.js code, save the app.js file. Then, go back to your terminal or command prompt and navigate to the directory where the file is located using the cd command.
6. Execute the Node.js file: To run the Node.js file, use the following command:
Copy code
node app.js
This command instructs Node.js to execute the code in the app.js file. If everything is set up correctly, you should see the output of your code in the terminal.
Congratulations! You have successfully run a Node.js file. You can continue writing more complex applications using Node.js by exploring its vast ecosystem of libraries and frameworks.
