Looks like you did the hardest part of preparing new database for Meteor. Meteor pretty much requires JavaScript implementation of database. Having that, you can create some alternative to MongoDB.
Keep up great work!
I must say, there seems to be a lot of work to be done, before we can call this implementation "stable" for kind of quality bar Minimongo (https://github.com/meteor/meteor/tree/devel/packages/minimon...) has in Meteor. It is not uncommon to see Reqlite queries to fail because of simple bugs.
Not to say that the library is hopeless, Neumino did a lot of grunt work that makes it easy to test and contribute. See this thread where we discuss the missing functionality: https://github.com/neumino/reqlite/issues/3
Single-binary tool with an embedded RethinkDB, syncing with a master instance when it's connected to the internet - one can dream.
const PouchDB = require('pouchdb');
const localDB = new PouchDB('db');
const remoteDB = new PouchDB('http://192.168.1.100:5984/db');
// remote db can be a CouchDB or PouchDB server.
localDB.sync(remoteDB);
It should be pretty hard to make a query fail beside the issues currently opened.
