'Change PouchDB directory in Electron

I would like change PouchDB directory in my Electron App. When i update my APP (re-install), all my data are destroyed.

So, i would like change my PouchDB directory for no remove my data when i re-install my App.

My code :

import PouchDB from 'pouchdb';
const Presentation = new PouchDB('~/test/db');

This return an error :

err {type: "OpenError", name: "OpenError", cause: Error: IO error: ~/test/db/LOCK: Aucun fichier ou dossier de ce type, message: "IO error: ~/test/db/LOCK: Aucun fichier ou dossier de ce type", stack: "OpenError: IO error: ~/test/db/LOCK: Aucun fichier…es/abstract-leveldown/abstract-leveldown.js:39:16"}

Anyone know how i can change my directory or just not remove my data when i re-install my Electron App ?

Thank you community !

~ is a Bash feature called "tilde expansion". It's a function of the shell, electron can't process it. Use new PouchDB('./test/db') record instead.

You can use pouchdb-dump-cli package to export database dump and then import it using pouchdb-load package.

The IO error is happening because pouch db cannot create the folder in the specified location. Electron apps usually need to store configs, local db files in the appData + appName location. This location has full access to the app.

const appName='<Electron App Name>'
const db = new PouchDB(
    path.join(app.getPath('appData'), appName, "db")
  );
