Node.js - get files from directory (recursively) asynchronous example

In this article, we would like to show you how to get all files from a directory (including subdirectories) in Node.js.

Practical example

Project structure:

directory/
 ├── one.txt
 └── directory2/
 |      └── two.json
 └── directory3/
        └── three.html

Code: 

const fs = require('fs/promises');
const path = require('path');

const getFilesFromDirectory = async (directoryPath) => {
    const filesInDirectory = await fs.readdir(directoryPath);
    const files = await Promise.all(
        filesInDirectory.map(async (file) => {
            const filePath = path.join(directoryPath, file);
            const stats = await fs.stat(filePath);
            
            if (stats.isDirectory()) {
                return getFilesFromDirectory(filePath);
            } else {
                return filePath;
            }
        })
    );
    return files.filter((file) => file.length); // return with empty arrays removed
};

const displayFiles = async () => {
    console.log(await getFilesFromDirectory('C:\\directory'));
};

displayFiles();

Output: 

[
  'one.txt',
  'two.json',
  'three.html'
]
