Node.js - get file names with extensions from array of paths
0 points
In this article, we would like to show you how to get file name with extension from path array in Node.js.
Quick solution:
xxxxxxxxxx1
const path = require('path');2
3
// example array of paths4
const paths = ['C:/app/index.js', 'C:/app/module1.js', 'C:/app/module2.js'];5
const names = paths.map(x => path.basename(x));6
7
console.log(names); // [ 'index.js', 'module1.js', 'module2.js' ]
1. Import path module using:
xxxxxxxxxx1
const path = require('path');2. Use path.basename() method with the path you want to get the filename from as an argument.
Practical example:
xxxxxxxxxx1
const path = require('path');2
3
// example array of paths4
const paths = ['C:/app/index.js', 'C:/app/module1.js', 'C:/app/module2.js'];5
6
const result = [];7
8
// get file names with extensions9
for (const pth of paths) {10
result.push(path.basename(pth));11
}12
13
console.log(result); // [ 'index.js', 'module1.js', 'module2.js' ]Output:
xxxxxxxxxx1
[ 'index.js', 'module1.js', 'module2.js' ]Note:
In this solution we used
for...ofloop to iterate through thepathsarray, but you can use any other method from the following article:
