Node.js - check if path is relative

In this article, we would like to show you how to check if path is relative in Node.js.

1. Import path module using:

const path = require('path');

2. Use path.isAbsolute() method with the path you want to check as an argument to find out if it is absolute (true) or relative (false).

Practical example:

const path = require('path');

// example paths
const relativePath = './index.js';
const absolutePath = 'C:/projects/app/index.js';

// check if path is absolute
const result1 = path.isAbsolute(relativePath);
const result2 = path.isAbsolute(absolutePath);

console.log(result1); // false
console.log(result2); // true

Output:

false
true
