Node.js - get file names with extensions from array of paths

In this article, we would like to show you how to get file name with extension from path array in Node.js.

Quick solution:

const path = require('path');

// example array of paths
const paths = ['C:/app/index.js', 'C:/app/module1.js', 'C:/app/module2.js'];
const names = paths.map(x => path.basename(x));

console.log(names); // [ 'index.js', 'module1.js', 'module2.js' ]

Practical example

1. Import path module using:

const path = require('path');

2. Use path.basename() method with the path you want to get the filename from as an argument.

Practical example:

const path = require('path');

// example array of paths
const paths = ['C:/app/index.js', 'C:/app/module1.js', 'C:/app/module2.js'];

const result = [];

// get file names with extensions
for (const pth of paths) {
    result.push(path.basename(pth));
}

console.log(result); // [ 'index.js', 'module1.js', 'module2.js' ]

Output:

[ 'index.js', 'module1.js', 'module2.js' ]

Note:

In this solution we used for...of loop to iterate through the paths array, but you can use any other method from the following article:
