Question

I\'m trying to get a list of the names of all the files present in a directory using Node.js. I want output that is an array of filenames. How can I do this?

Answer 1

Get sorted filenames. You can filter results based on a specific extension such as '.txt', '.jpg' and so on.

import * as fs from 'fs';
import * as Path from 'path';

function getFilenames(path, extension) {
    return fs
        .readdirSync(path)
        .filter(
            item =>
                fs.statSync(Path.join(path, item)).isFile() &&
                (extension === undefined || Path.extname(item) === extension)
        )
        .sort();
}
