How to see where nodejs is installed

Node.js is a very popular open source back-end program development tool. It is built on the Chrome V8 JavaScript engine. By using this modern JavaScript framework, you can easily build high-performance, highly scalable, and highly reliable web applications. However, when you want to debug or use Node.js, you need to know exactly where it is installed on your machine.

This article will explore how to find the Node.js installation location and how to verify that your Node.js is installed correctly.

Node.js installation location

The installation location of Node.js depends on the operating system you are using and the version of the installer. Different installers (e.g. .msi files for Windows or .dmg files for Mac) typically install Node.js into different directories.

The following are common locations where Node.js may be installed on various operating systems:

• Windows systems: By default, Node.js is installed in C:Program Files
  odejs directory.
• MacOS system: By default, Node.js is installed in the /usr/local/bin/node directory.
• Linux system: For Debian/Ubuntu distributions, Node.js is usually installed in the /usr/bin/nodejs directory.

But please note that these locations may depend on your installer, version, and configuration. If you're not sure, here are a few ways to confirm.

How to confirm the Node.js installation location

Method 1: Using a command prompt or terminal window

When you open a new command prompt or terminal window, you You can verify that Node.js is installed correctly on your machine by typing "node" and pressing Enter. If you see the Node.js version number, congratulations, it's installed. On Windows, the command prompt's path display should show the location of node.exe. On Mac and Linux, the terminal window's path display should show the location of the node.

You can enter the following code at the command prompt (on Windows) or terminal (on Mac and Linux) to view the installation path of Node.js:

• Windows systems:

  where node

This will output the location of Node.js on your machine. If you see the output, for example: C:Program Files
odejs
ode.exe, Node.js is installed in the C:Program Files
odejs directory by default.

• MacOS and Linux systems:

  which node

This will output the location of Node.js on your machine . If you see the output, for example: /usr/local/bin/node, Node.js is installed in the /usr/local/bin directory by default.

Method 2: Use online services in the browser

To quickly verify whether you have installed Node.js correctly, please use online services such as: repl.it and CodeSandbox. These online services allow you to run Node.js code in your browser and display the Node.js output in the browser window.

You can try to write the simplest Node.js program and run it on an online service, for example:

console.log("Hello, World!");

This will output "Hello, World!" to the browser's console to prove that your Node.js is installed correctly.

Conclusion

Now you know how to find the location of Node.js on your machine. You can enter "node" directly into a command prompt or terminal window, or you can use an online service to verify that your Node.js is installed correctly. No matter which method you use, it's easy to find the location of your Node.js installation, and you can start writing your Node.js applications.
