Configuring PouchDB with LevelDB to store data within User's Home folder

pouchDBElectron.js

//When using pouchDB within your Electron app, you may want to use different locations for the DB file during development vs releasing the app. 
//When distributing the app, you would want to store the data within the $HOME/.config/YourApp/data as per convention on Ubuntu. 

//to access the environment variable HOME in the renderer process. See https://github.com/electron/electron/issues/3306
const remote = require('electron').remote;
//we cannot use ~ in the path of leveldb as that is not correct way. See https://github.com/Level/levelup/issues/120. Thus use env.HOME
let dbFilePath = remote.process.env.HOME + '/.config/myapp/data/';
if (process.env.NODE_ENV === 'development') {
  dbFilePath = './data/';
}

let db = new PouchDB(dbFilePath);
