Node.js - list files recursively from directory (synchronous mode)

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

Practical example

Note: the source code was tested under Windows.

Directory structure:

C:/directory/
    ├── text.txt
    ├── resources/
    │    └── data.json
    └── pages/
         └── index.html

Source code: 

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

const listFiles = (directoryPath, filesPaths = []) => {
    for (const fileName of fs.readdirSync(directoryPath)) {
        const filePath = path.join(directoryPath, fileName);
        const fileStat = fs.statSync(filePath);
        if (fileStat.isDirectory()) {
            listFiles(filePath, filesPaths);
        } else {
            filesPaths.push(filePath);
        }
    }
    return filesPaths;
};


// Usage example:

console.log(listFiles('C:\\directory'));

Output: 

[
    'C:\\directory\\readme.txt',
    'C:\\directory\\pages\\index.html',
    'C:\\directory\\resources\\data.json'
]
