Node.js - get platform-specific path segment separator

In this article, we would like to show you how to get a platform-specific path segment separator in Node.js.

Quick solution:

xxxxxxxxxx

const path = require('path');

​

console.log(path.sep);  // \  <-- on windows

                        // /  <-- on Linux/Unix (POSIX)

1. Import path module using:

xxxxxxxxxx

const path = require('path');

2. Access to path.sep property that provides the platform-specific path segment separator:

• \ on Windows (sometimes on Japanese Windows you can see in the path ¥ used as separator)
• / on Linux/Unix (POSIX)

3. Motivation: having access to a separator you can do platform-independent operations on the paths,
e.g. filePath.split(path.sep).

xxxxxxxxxx

const path = require('path');

​

console.log(path.sep);

Output (on Windows):

xxxxxxxxxx
