Form File or Directory Path String in Node.js

Last updated on 23 Jul, 2021

Path module in Node.js provides utilities to work with file or directory paths. It can be accessed using:

const path = require("path");

If we need to join different path segments to form a valid path string, we can use path.join().

const filePath = path.join("apple", "banana", "orange"); // apple/banana/orange

The separator used to join the path is platform specific. Based on the OS, path.join() automatically handles it.

All the arguments passed to join() should be a string. Otherwise, it will throw a TypeError.
