How to persist data in an Electron app? [closed]

NeDB is the only suggested or featured tool as an embedded persistent database for Electron by Electron, currently. – http://electron.atom.io/community/

It’s also could be useful to store user settings if settings are complex.

Why NeDB could be a better solution on this case?

Embedded persistent or in memory database for Node.js, nw.js, Electron
and browsers, 100% JavaScript, no binary dependency. API is a subset
of MongoDB’s and it’s plenty fast. – NeDB

Creating or loading a database:

var Datastore = require('nedb')
  , db = new Datastore({ filename: 'path/to/datafile', autoload: true });
// You can issue commands right away

Inserting a document:

var doc = { hello: 'world'
               , n: 5
               , today: new Date()
               , nedbIsAwesome: true
               , notthere: null
               , notToBeSaved: undefined  // Will not be saved
               , fruits: [ 'apple', 'orange', 'pear' ]
               , infos: { name: 'nedb' }
               };

db.insert(doc, function (err, newDoc) {   // Callback is optional
  // newDoc is the newly inserted document, including its _id
  // newDoc has no key called notToBeSaved since its value was undefined
});

Finding documents:

// Finding all inhabited planets in the solar system
db.find({ system: 'solar', inhabited: true }, function (err, docs) {
  // docs is an array containing document Earth only
});

The list goes on…
