Node.js - get file name without extension from path

In this article, we would like to show you how to get file name without extension from path in Node.js.

1. Import path module using:

const path = require('path');

2. Use path.extname() method with the path you want to get the filename from as an argument to get the file extension. We need to know the file extension, so we can get rid of it in the next step.

3. Use path.basename() method with the path and the optional extension argument so the file extension will be removed leaving only the file name.

Practical example:

const path = require('path');

// example path
const myPath = 'C:/projects/app/index.js';

// get file extension
const extension = path.extname(myPath);

// get file name without extension
const result = path.basename(myPath, extension);

console.log(result); // index

Output:

index.js

Note:

The path.basename() method with one argument (myPath) returns file name with extension from given path.
