Use an encrypted file as your database instead of mongodb for your node/express app

How can I use an encrypted file as your database instead of MongoDB or MySQL for your NodeJS/express app?

where you will give your DB will be of a JSON format and there will be a service that backs it up at regular interval.

It could look like this

{
  "info": {
    "version": "0.0.1",
    "name": "Give your DB a name"
  },
  "data": {

  }
}

and have methods like 

myDB.info() // => {"version" : "0.0.2", "name": "demo DB"}

myDB.get('foo'); // => 'bar'

myDB.set('foo', 'bar');

myDB.delete(key);

myDB.backup(function(err) {
    if(err) throw err;
    else console.log('DB backed up at %s', new Date().toString());
});

myDB.search('stats.comments_lookup[{stats.page.id}]', function(res) {
    console.log("search result: ", res);
});

I saw this npm package called express-db but it's outdated and not maintained. Any better option or way of doing this?

Instead of using encrypted database or files, just encrypt data and store it in database.

You can use crypto-js module

var CryptoJS = require("crypto-js");

// Encryption 
var ciphertext = CryptoJS.AES.encrypt('my message', 'secret key 123');
//Store it in any database

//Retrieve from database
// Decryption 
var bytes  = CryptoJS.AES.decrypt(ciphertext.toString(), 'secret key 123');
var plaintext = bytes.toString(CryptoJS.enc.Utf8);

console.log(plaintext);

Advantage
In most cases you don't really need to encrypt entire data in a data set. So just encrypt sensitive data and store other data as plain text. Your application will run faster as encryption is really a CPU intensive process.
