node.js fs.readdir recursive directory search

Question

Any ideas on an async directory search using fs.readdir? I realise that we could introduce recursion and call the read directory function with the next directory to read, bu

Here's a recursive method of getting all files including subdirectories.

const FileSystem = require("fs");
const Path = require("path");

//...

function getFiles(directory) {
    directory = Path.normalize(directory);
    let files = FileSystem.readdirSync(directory).map((file) => directory + Path.sep + file);

    files.forEach((file, index) => {
        if (FileSystem.statSync(file).isDirectory()) {
            Array.prototype.splice.apply(files, [index, 1].concat(getFiles(file)));
        }
    });

    return files;
}
