function

fs.promises.readdir

options?: null | BufferEncoding | ObjectEncodingOptions & { recursive: boolean; withFileTypes: false }

): Promise<string[]>;

Reads the contents of a directory.

The optional options argument can be a string specifying an encoding, or an object with an encoding property specifying the character encoding to use for the filenames. If the encoding is set to 'buffer', the filenames returned will be passed as Buffer objects.

If options.withFileTypes is set to true, the returned array will contain fs.Dirent objects.

import { readdir } from 'node:fs/promises';

try {
  const files = await readdir(path);
  for (const file of files)
    console.log(file);
} catch (err) {
  console.error(err);
}

@returns

Fulfills with an array of the names of the files in the directory excluding '.' and '..'.

Asynchronous readdir(3) - read a directory.

@param path

A path to a file. If a URL is provided, it must use the file: protocol.

@param options

The encoding (or an object specifying the encoding), used as the encoding of the result. If not provided, 'utf8' is used.
