'fileSystemModule' was not found in '@nativescript/core'

Question

Trying to write to a local file in Android.

Tried import {fileSystemModule} from "@nativescript/core"; but get error 'fileSystemModule' was not found in '@nativescript/core'.

Have also tried import {fileSystemModule} from "@nativescript/core/file-system" but it doesn't exist. I'm using plain Javascript.

Nativescript 8.0.2

Answer 1

The import paths are updated in the recent versions of NativeScript. You can access these directly now without having to go through fileSystemModule. See code below:

import { knownFolders, File, Folder } from '@nativescript/core';

To write to a local file using the latest NativeScript would look like this:

writeToFile(): void {
  const folder = knownFolders.documents().getFolder(FOLDER_NAME);
  const file = folder.getFile(FILE_NAME.txt);
  file.writeText(SOME_STRING_TO_WRITE_TO_FILE);
}

To write to an accessible location in Android, you can use the following:

writeToFile(): void {
    const folderPath = path.join(android.os.Environment.getExternalStorageDirectory().getAbsolutePath().toString())
    const folder = Folder.fromPath(folderPath);
    const file = folder.getFile(FILE_NAME.txt);
    file.writeText(SOME_STRING_TO_WRITE_TO_FILE);
}
