Node.js - resolve path

In this article, we would like to show you how to resolve path in Node.js.

1. Import path module using:

const path = require('path');

2. Use path.resolve() method that resolves the specified paths into an absolute path.

Practical example:

const path = require('path');

// current directory
console.log('CURRENT DIRECTORY: ' + __dirname);

const path1 = path.resolve('public/images', 'logo.png');
console.log('PATH 1: ' + path1);

const path2 = path.resolve('/public/images', 'logo.png');
console.log('PATH 2: ' + path2);

const path3 = path.resolve('public', 'images', 'logo.png');
console.log('PATH 3: ' + path3);

Output:

CURRENT DIRECTORY: C:\projects\app
PATH 1: C:\projects\app\public\images\logo.png
PATH 2: C:\public\images\logo.png
PATH 3: C:\projects\app\public\images\logo.png

Note:

If no path segments are specified as parameters, the absolute path of the current directory is used.
