Embed RethinkDB into Electron (or NodeJS) app

I'm building an Electron app, specifically a crypto-currency wallet, so I need all the information stored locally on the user's machine and should not be synced to any server.

I like RethinkDB and would like to use it, but I can't find a way to embed it into the app.

I want the database to launch when the app starts, and shutdown when the app closes... in other words have it embedded into the app.

Is this possible with Rethinkdb? There's no relevant info on the page detailing how to start-up the db but perhaps this can be done anyways?

As long as you are storing the user data on their local machine. I believe you should use the embedded database but not the client-server database engine. Of course, we can use any database in our Electron application but in most cases, we don't need any client-server db engine as long as we just need a simple library or script that can store and manage the local db file.

RethinkgDB is a great database library but it's a client-server pattern. Please use SQLite instead. SQLite is not a client-server database engine. Rather, it is embedded into the end program. As the below code snippets show, we just need to set the db file path where all data will be stored.

Query syntax is the same as PostgreSQL.

const sqlite3 = require('sqlite3');

const database = new sqlite3.Database('./public/db.sqlite3', (err) => {
    if (err) console.error('Database opening error: ', err);
});

ipcMain.on('asynchronous-message', (event, arg) => {
    const sql = arg;
    database.all(sql, (err, rows) => {
        event.reply('asynchronous-reply', (err && err.message) || rows);
    });
});

In addition, I was used to using keytar to keep sensitive data like private keys and credentials of wallet.
