Node.js Path Module

Last Updated : 16 Jul, 2026

The path module provides utilities to handle and manipulate file and directory paths in a platform-independent way.

  • Ensures consistent behavior across different operating systems
  • Supports operations like joining, resolving, and parsing paths
  • Helps avoid errors in manual path handling

Installation Step (Optional)

Installation is an optional step as the path module is a built-in module in Node.js. Install the assert module using the following command:

npm install path

Importing the Module

To start using the path module in your Node.js application, import it as follows:

const path = require('path');

Path Methods

The path module provides methods to create, analyze, and manipulate file and directory paths in a platform-independent manner.

Method

Description

path.join()

Joins multiple path segments into a single path.

path.resolve()

Resolves a sequence of paths into an absolute path.

path.normalize()

Normalizes a path by resolving . and .. segments.

path.isAbsolute()

Returns true if the path is an absolute.

path.basename()

Returns the last portion of a path (file name).

path.dirname()

Returns the directory name of a path.

path.extname()

Returns the file extension of a path.

path.parse()

Parses a path into an object (root, dir, base, etc.).

path.format()

Constructs a path string from a parsed path object.

path.relative()

Computes the relative path between two paths.

path.sep

Platform-specific path separator (/ on POSIX, \ on Windows).

path.delimiter

Platform-specific delimiter (: on POSIX, ; on Windows).

Example: Uses path.extname() to extract a file extension, useful for identifying or filtering file types.

JavaScript 
console.clear();
const path = require('path');

// Define a file path
const filePath = '/users/gfg/documents/report.pdf';

// Extract the file extension
const fileExtension = path.extname(filePath);

console.log(`File Extension: ${fileExtension}`);

Output:

File Extension: .pdf

Example: Uses path.resolve() to convert a sequence of path segments into an absolute path.

JavaScript 
console.clear();
const path = require('path');
// Resolving an absolute path from segments
const absolutePath = path.resolve('users', 'gfg', 'documents');
console.log(absolutePath);

Output 

/your/current/directory/users/gfg/documents

Benefits of Path Module

  • Provides cross-platform utilities for handling file paths consistently across operating systems.
  • Simplifies path joining, resolving, parsing, and formatting with built-in methods.
  • Normalizes file paths and handles edge cases to reduce errors in path operations.
  • Improves code readability by replacing manual string manipulation with cleaner path methods.
  • Comes built into Node.js, so no external dependencies are required.
