Classes ​

Dirent ​

A representation of a directory entry, which can be a file or a subdirectory within the directory. A directory entry is a combination of the file name and file type pairs.

Additionally, when promises.readdir or readdirSync is called with the withFileTypes option set to true, the resulting array is filled with fs.Dirent objects, rather than strings.

new Dirent(): Dirent

Returns ​

Dirent

StatSyncFn() ​

Extends ​

  • Function

StatSyncFn(path: string): Stats

Parameters ​

ParameterType
pathstring

Returns ​

Stats

Type Aliases ​

Mode ​

Mode = number

PathLike ​

PathLike = string

Valid types for path values in "fs".

Variables ​

statSync ​

const statSync: StatSyncFn

Synchronous stat - Get file status.

Param ​

A path to a file.

Functions ​

accessSync() ​

accessSync(path: string, mode?: number): void

Synchronously tests a user's permissions for the file or directory specified by path. The mode argument is an optional integer that specifies the accessibility checks to be performed. mode should be either the value fs.constants.F_OK or a mask consisting of the bitwise OR of any of fs.constants.R_OK, fs.constants.W_OK, and fs.constants.X_OK (e.g.fs.constants.W_OK | fs.constants.R_OK). Check File access constants for possible values of mode.

If any of the accessibility checks fail, an Error will be thrown. Otherwise, the method will return undefined.

js
import { accessSync, constants } from 'fs';

try {
  accessSync('etc/passwd', constants.R_OK | constants.W_OK);
  console.log('can read/write');
} catch (err) {
  console.error('no access!');
}

Parameters ​

ParameterTypeDescription
pathstring-
mode?number

Returns ​

void

chmodSync() ​

chmodSync(path: string, mode: number): void

For detailed information, see the documentation of the asynchronous version of this API: chmod.

See the POSIX chmod(2) documentation for more detail.

Parameters ​

ParameterType
pathstring
modenumber

Returns ​

void

mkdirSync() ​

mkdirSync(path: string, options?: MakeDirectoryOptions): string

Synchronously creates a directory. Returns the path.

See the POSIX mkdir(2) documentation for more details.

Parameters ​

ParameterType
pathstring
options?MakeDirectoryOptions

Returns ​

string

mkdtempSync() ​

mkdtempSync(prefix: string): string

Returns the created directory path.

For detailed information, see the documentation of the asynchronous version of this API: promises.mkdtemp.

Parameters ​

ParameterType
prefixstring

Returns ​

string

readdirSync() ​

Call Signature ​

readdirSync(path: string, options?: object): string[]

Reads the contents of the directory.

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

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

Parameters ​
ParameterType
pathstring
options?{ recursive?: boolean; withFileTypes?: false; }
options.recursive?boolean
options.withFileTypes?false
Returns ​

string[]

Call Signature ​

readdirSync(path: string, options: object): Dirent[]

Synchronous readdir (2) - read a directory.

Parameters ​
ParameterTypeDescription
pathstringA path to a file. If a URL is provided, it must use the file: protocol.
options{ recursive?: boolean; withFileTypes: true; }If called with withFileTypes: true the result data will be an array of Dirent.
options.recursive?boolean-
options.withFileTypestrue-
Returns ​

Dirent[]

readFileSync() ​

Call Signature ​

readFileSync(path: string, options?: { encoding?: null; } | null): Buffer

Returns the contents of the path.

For detailed information, see the documentation of the asynchronous version of this API: promises.readFile.

If the encoding option is specified then this function returns a string. Otherwise it returns a buffer.

Parameters ​
ParameterTypeDescription
pathstringA path to a file.
options?{ encoding?: null; } | null-
Returns ​

Buffer

Call Signature ​

readFileSync(path: string, options: BufferEncoding | { encoding: BufferEncoding; }): string

Returns ​

string

renameSync() ​

renameSync(oldPath: string, newPath: string): void

void

rmdirSync() ​

rmdirSync(path: string, options?: RmDirOptions): void
