Node.js Path Module

In Node.js, the path module is used to manipulate file paths. It provides a way to work with both absolute and relative paths, as well as platform-specific file path separators. In this tutorial, we'll discuss how to use the path module in Node.js.

Syntax

The syntax for using the path module in Node.js is as follows:

const path = require('path');

This imports the path module and makes it available for use in your code.

Example

Let's say we want to create a file path from a directory and file name. Here's how we can use the path module to achieve this:

const path = require('path');

const directory = '/user/documents';
const filename = 'document.txt';

const filepath = path.join(directory, filename);

console.log(filepath); // Output: /user/documents/document.txt

Output

When we run the example code above, the output will be:

/user/documents/document.txt

This is the file path generated by the path.join method.

Explanation

In the example above, we used the path module to create a file path from a directory and file name. We imported the path module using the require function, then used the join method to concatenate the directory and filename and generate the file path.

Use

The path module in Node.js is used for:

• Working with file paths
• Normalizing file paths
• Resolving file paths
• Parsing file paths
• Joining file paths

Important Points

• The path module is built-in to Node.js, so you don't need to install it separately.
• The path module can be used on both Windows and Unix-like operating systems.
• The path.join method concatenates multiple path segments using the platform-specific file path separator.
• The path.resolve method resolves a sequence of paths or path segments into an absolute path.

Summary

In this tutorial, we discussed how to use the path module in Node.js to manipulate file paths. We covered the syntax, example, output, explanation, use, and important points of the path module in Node.js. With this knowledge, you can now use the path module in your Node.js applications to work with file paths and filenames in a platform-independent manner.
