How to check nodejs path

Node.js is a very popular JavaScript runtime environment that allows developers to write server-side applications using JavaScript. In Node.js, knowing the application path is a very common task, as getting the path information is very useful for reading local files or manipulating the file system. Here are a few ways to view your Node.js path.

1. Use __dirname variable

In Node.js, __dirname is a global variable that represents the folder path of the current module. You can use the __dirname variable in the code to view the path where the current module is located.

For example, the following code shows how to use the __dirname variable in Node.js:

console.log(__dirname)

Running this code will output the path to the current file.

2. Use the process.cwd() method

The process.cwd() method returns the current working directory of the Node.js process. This method can be used in code to view the path of a Node.js application.

For example, the following code shows how to use the process.cwd() method in Node.js:

console.log(process.cwd())

Running this code will output the path to the Node.js application.

3. Using the path module

The path module is one of the core modules in Node.js for handling file paths. You can use methods in this module to generate, convert, or parse file paths. The path module can parse relative paths, absolute paths, ../, etc.

For example, the following code shows how to use the path module in Node.js to view the absolute path of the current module:

const path = require('path')
console.log(path.resolve(__dirname))

Running this code will output the absolute path of the current module.

The above are several ways to view the Node.js path. Regardless of which method is used, knowing path information is very useful for developers because it helps them locate files and manipulate the file system.
