i’ve tested : rm -rf /node_modules | ionic state reset | npm install

I see under node_modules/@types/cordova-plugin-file/index.d.ts the description of fileEntry…so i don’t understand !

Same error…any idea ?

Thx !

You can use the wrapper provided by Ionic Native for the file plugin, instead of using @types/cordova-plugin-file

See for documentation.

Here’s a quick example:

import { File } from 'ionic-native';

  .then(() => console.log('File exists'))
  .catch((e) => console.log('File doesnt exist', e));

Yeah ! It’s OK for FileEntry and resolveLocalFileSystemUrl but I still have the following error :

cordova.file.* cordova not found

In fact, cordova-plugin-file exposes some cordova.* string to define file store (cordova-plugin-file) .

The ionic-native File plugin doesn’t expose the cordova.* string. So it’s why I use @types/cordova-plugin-file because it describes cordova.file.*.

May be, i need to put a issue/PR to expose this interface into the File ionic native plugin ?

Well you still don’t need the @types
you can do something like this:

declare var cordova: any;


An issue/PR to add it to the Ionic Native wrapper would be helpful too :slight_smile:

Just need to add something like this to the File class:

get cacheDirectory(): string { 
  return cordova.file.cacheDirectory;
