Table of Contents

Getting Started

Just install & use:

$ npm install --save @dr.pogodin/react-native-fs

Note: Windows auto-link command (at least as it was needed for example project to install the lib hosted in the parent folder):

npx react-native autolink-windows --sln "windows\ReactNativeFsExample.sln" --proj "windows\ReactNativeFsExample\ReactNativeFsExample.vcxproj"

Project History & Roadmap

This project is a fork of the upstream react-native-fs library, which has been abandoned by its owners and maintainers. This forks aims to keep the library on par with the latest React Native standards, with support of the New Architecture, backward compatibility with the Old Architecture; and to further develop the library according to the best industry practices.

To migrate from the legacy react-native-fs install this fork_

npm install --save @dr.pogodin/react-native-fs

then upgrade its imports in the code:

// The legacy RNFS was imported like this:
import RNFS from 'react-native-fs';

// Instead, this fork should be imported like this:
import * as RNFS from '@dr.pogodin/react-native-fs';
// or (preferrably) you should import separate constants / functions you need
// like:
import {
  TemporaryDirectoryPath,
  writeFile,
} from '@dr.pogodin/react-native-fs';

ROADMAP:

Background Downloads Tutorial (iOS)

Background downloads in iOS require a bit of a setup.

First, in your AppDelegate.m file add the following:

#import <RNFSBackgroundDownloads.h>

...

- (void)application:(UIApplication *)application
  handleEventsForBackgroundURLSession:(NSString *)identifier
  completionHandler:(void (^)())completionHandler
{
  [RNFSBackgroundDownloads
    setCompletionHandlerForIdentifier:identifier
    completionHandler:completionHandler];
}

The handleEventsForBackgroundURLSession method is called when a background download is done and your app is not in the foreground.

We need to pass the completionHandler to RNFS along with its identifier.

The JavaScript will continue to work as usual when the download is done but now you must call RNFS.completeHandlerIOS(jobId) when you're done handling the download (show a notification etc.)

BE AWARE! iOS will give about 30 sec. to run your code after handleEventsForBackgroundURLSession is called and until completionHandler is triggered so don't do anything that might take a long time (like unzipping), you will be able to do it after the user re-launces the app, otherwide iOS will terminate your app.

Examples

These are legacy examples, and should be revised, there is an Example app in the /example folder of the codebase, you probably should rather check it than these examples.

Basic

// require the module
var RNFS = require('react-native-fs');

// get a list of files and directories in the main bundle
RNFS.readDir(RNFS.MainBundlePath) // On Android, use "RNFS.DocumentDirectoryPath" (MainBundlePath is not defined)
  .then((result) => {
    console.log('GOT RESULT', result);

    // stat the first file
    return Promise.all([RNFS.stat(result[0].path), result[0].path]);
  })
  .then((statResult) => {
    if (statResult[0].isFile()) {
      // if we have a file, read it
      return RNFS.readFile(statResult[1], 'utf8');
    }

    return 'no file';
  })
  .then((contents) => {
    // log the file contents
    console.log(contents);
  })
  .catch((err) => {
    console.log(err.message, err.code);
  });

File creation

// require the module
var RNFS = require('react-native-fs');

// create a path you want to write to
// :warning: on iOS, you cannot write into `RNFS.MainBundlePath`,
// but `RNFS.DocumentDirectoryPath` exists on both platforms and is writable
var path = RNFS.DocumentDirectoryPath + '/test.txt';

// write the file
RNFS.writeFile(path, 'Lorem ipsum dolor sit amet', 'utf8')
  .then((success) => {
    console.log('FILE WRITTEN!');
  })
  .catch((err) => {
    console.log(err.message);
  });

File deletion

// create a path you want to delete
var path = RNFS.DocumentDirectoryPath + '/test.txt';

return RNFS.unlink(path)
  .then(() => {
    console.log('FILE DELETED');
  })
  // `unlink` will throw an error, if the item to unlink does not exist
  .catch((err) => {
    console.log(err.message);
  });

File upload (Android and IOS only)

// require the module
var RNFS = require('react-native-fs');

var uploadUrl = 'http://requestb.in/XXXXXXX';  // For testing purposes, go to http://requestb.in/ and create your own link
// create an array of objects of the files you want to upload
var files = [
  {
    name: 'test1',
    filename: 'test1.w4a',
    filepath: RNFS.DocumentDirectoryPath + '/test1.w4a',
    filetype: 'audio/x-m4a'
  }, {
    name: 'test2',
    filename: 'test2.w4a',
    filepath: RNFS.DocumentDirectoryPath + '/test2.w4a',
    filetype: 'audio/x-m4a'
  }
];

var upload
= (response) => {
  var jobId = response.jobId;
  console.log('UPLOAD HAS BEGUN! JobId: ' + jobId);
};

var uploadProgress = (response) => {
  var percentage = Math.floor((response.totalBytesSent/response.totalBytesExpectedToSend) * 100);
  console.log('UPLOAD IS ' + percentage + '% DONE!');
};

// upload files
RNFS.uploadFiles({
  toUrl: uploadUrl,
  files: files,
  method: 'POST',
  headers: {
    'Accept': 'application/json',
  },
  fields: {
    'hello': 'world',
  },
  begin: uploadBegin,
  progress: uploadProgress
}).promise.then((response) => {
    if (response.statusCode == 200) {
      console.log('FILES UPLOADED!'); // response.statusCode, response.headers, response.body
    } else {
      console.log('SERVER ERROR');
    }
  })
  .catch((err) => {
    if(err.description === "cancelled") {
      // cancelled by user
    }
    console.log(err);
  });

API Reference

Constants

CachesDirectoryPath

const CachesDirectoryPath: string;

VERIFIED: Android, iOS, macOS, Windows.

The absolute path to the caches directory.

DocumentDirectoryPath

const DocumentDirectoryPath: string;

VERIFIED: Android, iOS, macOS, Windows.

The absolute path to the document directory.

IMPORTANT: DocumentDirectoryPath (iOS) will include an ID in the path that changes each build e.g ...Application/BCE32988-4C51-483B-892B-16671E3771C2/Documents.

Use relative paths and resolve the full path at runtime to avoid files not being found on new builds.

DownloadDirectoryPath

const DownloadDirectoryPath: string;

VERIFIED: Android, Windows. NOT SUPPORTED: iOS, macOS.

The absolute path to the download directory (on android and Windows only).

ExternalCachesDirectoryPath

const ExternalCachesDirectoryPath: string;

VERIFIED: Android, Windows (empty?). NOT SUPPORTED: iOS, macOS.

The absolute path to the external caches directory (android only).

ExternalDirectoryPath

const ExternalDirectoryPath: string;

VERIFIED: Android, iOS (empty?), macOS (empty?), Windows.

The absolute path to the external files, shared directory (android only).

ExternalStorageDirectoryPath

const ExternalStorageDirectoryPath: string;

VERIFIED: Android, iOS (empty?), macOS (empty?), Windows (empty?).

The absolute path to the external storage, shared directory (android only).

BEWARE: When using ExternalStorageDirectoryPath it's necessary to request permissions (on Android) to read and write on the external storage, here an example: React Native Offical Doc

LibraryDirectoryPath

const LibraryDirectoryPath: string;

VERIFIED: iOS, macOS, Windows (empty?). NOT SUPPORTED: Android.

The absolute path to the NSLibraryDirectory (iOS only).

MainBundlePath

const MainBundlePath: string;

VERIFIED: iOS, macOS, Windows. NOT SUPPORTED: Android.

The absolute path to the main bundle directory (not available on Android).

PicturesDirectoryPath

const PicturesDirectoryPath: string;

VERIFIED: Android, Windows. NOT SUPPORTED: iOS, macOS.

The absolute path to the pictures directory.

RoamingDirectoryPath

const RoamingDirectoryPath: string;

VERIFIED: Windows. NOT SUPPORTED: Android, iOS, macOS.

The absolute path to the roaming directory (Windows only).

TemporaryDirectoryPath

const TemporaryDirectoryPath: string;

VERIFIED: Android, iOS, macOS, Windows.

The absolute path to the temporary directory (falls back to Caching-Directory on Android).

BEWARE: The trailing slash might be inconsistent in this path! At the very least, on Android this constant does not have a slash in the end; but on iOS (new arch) it has it. It is something to unify in future.

Functions

appendFile()

function appendFile(filepath: string, contents: string, encoding?: string): Promise<void>;

VERIFIED: Android, iOS, macOS, Windows.

Appends content to a file.

completeHandlerIOS()

function completeHandlerIOS(jobId: number): void;

VERIFIED: well... not really verified, but is callable on iOS.

iOS only. For use when using background downloads, tell iOS you are done handling a completed download.

Read more about background downloads in the Background Downloads Tutorial (iOS) section.

copyAssetsFileIOS()

function copyAssetsFileIOS(
  imageUri: string,
  destPath: string,
  width: number,
  height: number,
  scale?: number,
  compression?: number,
  resizeMode?: string,
): Promise<string>;

BEWARE: After ensuring this method gets called correctly on iOS, calling it just crashes the example app for me. Though, I don't have much interest to dig into it now (not for free :)

iOS only.

Not available on Mac Catalyst.

Reads an image file from Camera Roll and writes to destPath. This method assumes the image file to be JPEG file. This method will download the original from iCloud if necessary.

One can use this method also to create a thumbNail from a video in a specific size. Currently it is impossible to specify a concrete position, the OS will decide which Thumbnail you'll get then. To copy a video from assets-library and save it as a mp4-file, refer to copyAssetsVideoIOS.

Further information: https://developer.apple.com/reference/photos/phimagemanager/1616964-requestimageforasset The promise will on success return the final destination of the file, as it was defined in the destPath-parameter.

copyAssetsVideoIOS()

function copyAssetsVideoIOS(videoUri: string, destPath: string): Promise<string>;

BEWARE: Similarly to copyAssetsFileIOS() I believe it gets correctly called on iOS, but it crashes the example app in my naive test. Perhaps I use it wrong, or something should be patched in the original implementation.

Not available on Mac Catalyst.

Copies a video from assets-library, that is prefixed with 'assets-library://asset/asset.MOV?...' to a specific destination.

copyFile()

function copyFile(from: string, into: string, options?: FileOptionsT): Promise<void>;

VERIFIED: Android, iOS, macOS, Windows.

Copies a file to a new destination. Throws if called on a directory.

Note: On Android and Windows copyFile() will overwrite destPath if it already exists. On iOS an error will be thrown if the file already exists. — beware, this has not been verified yet.

BEWARE: On Android copyFile() throws if called on a folder; on other platforms it does not throw, but it has not been verified yet, if it actually copies a folder with all its content there.

copyFileAssets()

function copyFileAssets(from: string, into: string): Promise<void>

VERIFIED: Android. NOT SUPPORTED: iOS, macOS, Windows.

Copies Android app's asset(s) to the specified destination.

If from points to a file, this function assumes into is a file path as well, and it copies the asset to that destination, overwriting the existing file at that destination, if any.

If from points to a folder, this function assumes into is a folder path as well, and it recursively copies the content of from into that destination, preserving the folder structure of copied assets, and overwriting existing files in the destination in case of conflicts. It does not clean the destination prior to copying into it, and it cannot overwrite files by folders and vice-versa. If into does not exist, it will be created, assuming its parent folder does exist (i.e. it does not attempt to create entire path as mkdir() does).

copyFileRes()

function copyFileRes(filename: string, destPath: string): Promise<void>

VERIFIED: Android. NOT SUPPORTED: iOS, macOS, Windows.

Android-only. Copies the file named filename in the Android app's res folder and copies it to the given destPath path. res/drawable is used as the source parent folder for image files, res/raw for everything else.

BEWARE: It will overwrite destPath if it already exists.

copyFolder()

copyFolder(from: string, into: string): Promise<void>;

VERIFIED: Windows NOT SUPPORTED: Android, iOS, macOS

Windows only. Copies content to a new location in a Windows-efficient way, compared to copyFile().

downloadFile()

function downloadFile(options: DownloadFileOptionsT): {
  jobId: number;
  promise: Promise<DownloadResultT>;
};

VERIFIED: Android, iOS, macOS, Windows \ BEWARE: Only basic functionality has been verified.

Downloads a file from options.fromUrl to options.toFile. It Will overwrite any previously existing file.

exists()

function exists(path: string): Promise<boolean>;

VERIFIED: Android, iOS, macOS, Windows.

Checks if an item exists at the given path.

existsAssets()

function existsAssets(path: string): Promise<boolean>;

VERIFIED: Android. NOT SUPPORTED: iOS, macOS, Windows.

Android-only. Checks if an item exists at the given path in the Android assets folder.

existsRes()

function existsRes(filename: string): Promise<boolean>;

VERIFIED: Android. NOT SUPPORTED: iOS, macOS, Windows.

Android-only. Check if the specified resource exists. res/drawable is used as the parent folder for image files, res/raw for everything else.

getAllExternalFilesDirs()

function getAllExternalFilesDirs(): Promise<string[]>;

VERIFIED: Android. NOT SUPPORTED: iOS, macOS, Windows.

Android-only. Returns an array with the absolute paths to application-specific directories on all shared/external storage devices where the application can place persistent files it owns.

getFSInfo()

function getFSInfo(): Promise<FSInfoResultT>;

VERIFIED: Android, iOS, macOS, Windows.

Provides information about free and total file system space.

hash()

function hash(path: string, algorithm: string): Promise<string>;

VERIFIED: Android, iOS, macOS, Windows.

Calculates file's hash.

isResumable()

function isResumable(jobId: number): Promise<bool>;

iOS only. Check if the the download job with this ID is resumable with resumeDownload().

Example:

if (await RNFS.isResumable(jobId) {
    RNFS.resumeDownload(jobId)
}

mkdir()

function mkdir(path: string, options?: MkdirOptionsT): Promise<void>;

VERIFIED: Android, iOS, macOS, Windows.

Creates folder(s) at path, and does not throw if already exists (similar to mkdir -p in Linux).

moveFile()

function moveFile(from: string, into: string): Promise<void>;

VERIFIED: Android, iOS, macOS, Windows.

Moves an item (a file, or a folder with files) to a new location. This is more performant than reading and then re-writing the file data because the move is done natively and the data doesn't have to be copied or cross the bridge.

Note: Overwrites existing file in Windows — To be verified, how does it behave on other systems, and whether it really overwrites items on Windows?

BEWARE: On Windows it currently does not allow moving folders with files, on other platforms it works fine.

pathForGroup()

function pathForGroup(groupIdentifier: string): Promise<string>;

VERIFIED: iOS.

iOS only. Returns the absolute path to the directory shared for all applications with the same security group identifier. This directory can be used to to share files between application of the same developer.

Invalid group identifier will cause a rejection.

For more information read the Adding an App to an App Group section.

pickFile()

function pickFile(options?: PickFileOptionsT): Promise<string[]>;

SUPPORTED: Android, iOS, macOS. NOT YET SUPPORTED: Windows.

Prompts the user to select file(s) using a platform-provided file picker UI, which also allows to access files outside the app sandbox.

BEWARE: On macOS (Catalyst) for this function to work you MUST go to Signing & Capabilities settings of your project, and inside its App Sandbox section to set File Access > User Selected Files to Read/Write value (with just Read the file picker on macOS opens and seemingly works, but rather than returning the picked up URL, it signals the operation has been cancelled). If it is left at the default None value the call to pickFile() will crash the app.

read()

function read(path: string, length = 0, position = 0, encodingOrOptions?: EncodingT | ReadFileOptionsT): Promise<string>;

VERIFIED: Android, iOS, macOS, Windows.

Reads length bytes from the given position of a file.

BEWARE: On Android and Windows read() called with zero length and position resolves to empty string; however on other platforms it resolves to the entire file content (same as readFile()). This behavior has been inherited from the legacy RNFS implementation, and is to be corrected in future.

Note: To read entire file at once consider to use readFile() instead.

Note: No matter the encoding, this function will always read the specified number of bytes from the given position, and then transform that byte chunk into a string using the given encoding; that is in constrast of, say, reading the given number of characters, if utf8 is given.

readdir()

function readdir(path: string): Promise<string[]>;

VERIFIED: Android, iOS, macOS.

Lists the content of given folder (names only — NodeJS-style). Note the lowercase d in the name, unlike in readDir().

BEWARE: There is no guarantees about the sort order of resolved listing.

readDir()

function readDir(path: string): Promise<ReadDirItem[]>;

VERIFIED: Android, iOS, macOS, Windows.

Lists the content of given absolute path.

BEWARE: There is no guarantees about the sort order of resolved listing.

BEWARE: On Windows the isDirectory() and isFile() methods of result currently return false for all items; also size value in the result is platform dependent for directories.

readDirAssets()

function readDirAssets(path: string): Promise<ReadDirItem[]>;

VERIFIED: Android. NOT SUPPORTED: iOS, macOS, Windows.

(Android only) Lists the content of a folder at the given path inside the Android assets folder.

readFile()

function readFile(path: string, encodingOrOptions?: EncodingT | ReadFileOptionsT): Promise<string>;

VERIFIED: Android, iOS, macOS, Windows.

Reads the file at path and return its content as a string.

Note: To read a selected fragment of the file see read().

Note: For base64 encoding this function will return file content encoded into Base64 format; for ascii it will fill each character of the result string with the code of corresponding byte in the file; and for utf8 (default) it will assume the source file is UTF8-encoded, and it will decode it into the result string (thus each result character will be corresponding to a group of 1-to-4 bytes of the source file).

BEWARE: You will take quite a performance hit if you are reading big files.

readFileAssets()

function readFileAssets(path: string, encoding?: EncodingT | ReadFileOptionsT): Promise<string>;

VERIFIED: Android. NOT SUPPORTED: iOS, macOS, Windows.

Android-only. Reads the file at path in the Android app's assets folder and return its contents. encoding can be one of utf8 (default), ascii, base64. Use base64 for reading binary files.

readFileRes

function readFileRes(filename: string, encoding?: EncodingT): Promise<string>;

VERIFIED: Android. NOT SUPPORTED: iOS, macOS, Windows.

Android-only. Reads the file named filename in the Android app's res folder and return contents. Only the file name (not folder) needs to be specified.

Original docs say: The file type will be detected from the extension and automatically located within res/drawable (for image files) or res/raw (for everything else). Good luck with it. The test in the example app does not work if the file extension is not included into the filename... but perhaps I've overlooked something.

resumeDownload()

function resumeDownload(jobId: number): void;

iOS only. Resume the current download job with this ID.

scanFile()

function scanFile(path: string): Promise<string | null>;

VERIFIED: Android. NOT SUPPORTED: iOS, macOS, Windows.

Android-only. Scan the file using Media Scanner.

stat()

function stat(path: string): Promise<StatResultT>;

VERIFIED: Android, iOS, macOS, Windows.

Stats an item at path. If the path is linked to a virtual file, for example Android Content URI, the originalPath can be used to find the pointed file path (beware — this has not been verified yet).

BEWARE: On Windows a bunch of stuff in the response is currently not compatible with the specs — size is a string rather than number, isDirectory() and isFile() do not work (always return false), etc. Also on Windows, even with those defects accounted for the test for this function tends to randomly fail on a regular basis. It thus requires more troubleshooting, but it is not a priority for now.

stopDownload()

function stopDownload(jobId: number): void;

VERIFIED: Android, iOS.

Aborts a file download job. The partial file will remain on the filesystem, and the promise returned from the aborted downloadFile() call will reject with an error.

stopUpload()

function stopUpload(jobId: number): void;

VERIFIED: iOS.

iOS only. Abort the current upload job with given ID.

NOTE: Unlike stopDownload() it does not cause the pending upload promise to reject. Perhaps, we'll change it in future to behave similarly.

touch()

function touch(filepath: string, mtime?: Date, ctime?: Date): Promise<void>;

VERIFIED: Android, iOS, macOS, Windows.

Alters creation and modification timestamps of the given file.

unlink()

function unlink(path: string): Promise<void>;

VERIFIED: Android, iOS, macOS, Windows.

Unlinks (removes) the item at path. If the item does not exist, an error will be thrown. Also recursively deletes directories (works like Linux rm -rf).

uploadFiles()

function uploadFiles(options: UploadFileOptionsT): {
  jobId: number;
  promise: Promise<UploadResultT>;
}

VERIFIED: Android, iOS, macOS, Windows

Uploads files to a remote location.

BEWARE: Only the most basic upload functionality has been tested so far in this library fork.

write()

function write(filepath: string, contents: string, position?: number, encoding?: EncodingT): Promise<void>;

VERIFIED: Android, iOS, macOS, Windows \ BEWARE: On Windows it seems to work differently from other platforms, throwing if attempting to write to a non-existing file.

Writes content to a file at the given random access position.

writeFile()

function writeFile(path: string, content: string, encodingOrOptions?: EncodingT | WriteFileOptionsT): Promise<void>

VERIFIED: Android, iOS, macOS, Windows.

Write the content to the file at path, overwritting it if exists already.

NOTE: With base64 encoding value this function will assume that given content is Base64-encoded already, and it will be decoded into the file; for ascii encoding each character of content will be written to one byte in the file, and the function will fail if any character is outside the U+0000 to U+00FF range (keep in mind, that regular JS strings have two-byte characters); and for utf8 encoding (default) it will encode content characters (which can be from U+0000 to U+FFFF in this case) into the corresponding UTF8 code (i.e. each source character will be turned into a group of 1-to-4 bytes in the written file).
