Node fs copy a folder

I am trying to copy a folder using Node fs module. I am familiar with readFileSync() and writeFileSync() methods but I am wondering what method I should use to copy a specified folder?

Save yourself the extra dependency with just 10 lines of native node functions

Add the following copyDir function:

const { promises: fs } = require("fs")
const path = require("path")

async function copyDir(src, dest) {
    await fs.mkdir(dest, { recursive: true });
    let entries = await fs.readdir(src, { withFileTypes: true });

    for (let entry of entries) {
        let srcPath = path.join(src, entry.name);
        let destPath = path.join(dest, entry.name);

        entry.isDirectory() ?
            await copyDir(srcPath, destPath) :
            await fs.copyFile(srcPath, destPath);
    }
}

And then use like this:

copyDir("./inputFolder", "./outputFolder")
