readdirSync - Node documentation
function readdirSync

Usage in Deno

import { readdirSync } from "node:fs";
readdirSync(
path: PathLike,
options?:
{ encoding: BufferEncoding | null; withFileTypes?: false | undefined; recursive?: boolean | undefined; }
| BufferEncoding
| null
,
): string[]

Reads the contents of the directory.

See the POSIX readdir(3) documentation for more details.

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 returned. If the encoding is set to 'buffer', the filenames returned will be passed as Buffer objects.

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

Parameters

path: PathLike
optional
options:
{ encoding: BufferEncoding | null; withFileTypes?: false | undefined; recursive?: boolean | undefined; }
| BufferEncoding
| null

Return Type

string[]
readdirSync(
path: PathLike,
options: { encoding: "buffer"; withFileTypes?: false | undefined; recursive?: boolean | undefined; } | "buffer",
): Buffer[]

Synchronous readdir(3) - read a directory.

Parameters

path: PathLike

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

options: { encoding: "buffer"; withFileTypes?: false | undefined; recursive?: boolean | undefined; } | "buffer"

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

Return Type

Buffer[]
readdirSync(
path: PathLike,
options?:
(ObjectEncodingOptions & { withFileTypes?: false | undefined; recursive?: boolean | undefined; })
| BufferEncoding
| null
,
): string[] | Buffer[]

Synchronous readdir(3) - read a directory.

Parameters

path: PathLike

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

optional
options:
(ObjectEncodingOptions & { withFileTypes?: false | undefined; recursive?: boolean | undefined; })
| BufferEncoding
| null

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

Return Type

string[] | Buffer[]
readdirSync(
path: PathLike,
options: ObjectEncodingOptions & { withFileTypes: true; recursive?: boolean | undefined; },
): Dirent[]

Synchronous readdir(3) - read a directory.

Parameters

path: PathLike

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

options: ObjectEncodingOptions & { withFileTypes: true; recursive?: boolean | undefined; }

If called with withFileTypes: true the result data will be an array of Dirent.
