In this article, we would like to show you how to get a list of the names of all directories in a specified directory in Node.js.

Quick solution:

xxxxxxxxxx
 
const fs = require('fs');
​
fs.readdir(pathToDirectory, { withFileTypes: true }, (error, files) => {
    const directoriesInDIrectory = files
        .filter((item) => item.isDirectory())
        .map((item) => item.name);
​
    console.log(directoriesInDIrectory);
});

Synchronous version:

xxxxxxxxxx
 
const fs = require('fs');
​
const directoriesInDIrectory = fs.readdirSync(pathToDirectory, { withFileTypes: true })
    .filter((item) => item.isDirectory())
    .map((item) => item.name);

Practical example

xxxxxxxxxx
 
const fs = require('fs');
​
fs.readdir('./', { withFileTypes: true }, (error, files) => {
    if (error) throw error;
    const directoriesInDIrectory = files
        .filter((item) => item.isDirectory())
        .map((item) => item.name);
​
    console.log(directoriesInDIrectory);
});
