Reqlite - RethinkDB in JavaScript

What is it?

Reqlite is an implementation of a ReQL server in JavaScript. Meaning that you can connect to reqlite with the RethinkDB driver and send queries (create a table, insert documents, filter them, open a chanfeed etc.

./bin/reqlite

Does it work?

Most of the methods work. There are currently 2000+ tests passing.

Why?

The main reasons why this project was started were:

• Provide an easy way for node developers to test their code without having to start a RethinkDB server.
• Maybe Meteor will use it to build a mini-rethinkdb - See meteor-rethinkdb
• Use it on Windows instead of running a Docker container in Vagrant
• Because it's kind of fun :-)

Version of RethinkDB supported

It currently tries to match RethinkDB 2.2.x.

Run tests

Most of the tests run queries against RethinkDB and reqlite at the same time, and compare the output. Start RethinkDB on port 28015

rethinkdb

And reqlite on port 28016:

node ./lib/node.js --port-offset 1

If you are developing on reqlite, you may want to use

nodemon lib/node.js -- -L --port-offset 1 --debug

Then run:

npm test

Use in the browser

Build

Run in the reqlite repository:

npm run browserify

You then need a driver to connect to reqlite. Clone rethinkdbdash and run:

npm run browserify

Note: The official JavaScript driver currently doesn't work with reqlite because it cannot use a fake tcp connection (yet).

Example

Import rethinkdbdash.js and reqlite.js in your page. Then you can write:

var Reqlite = require('reqlite');
// You cannot use a pool with reqlite
var r = require('rethinkdbdash')({pool: false});

var server = new Reqlite();
// This simulate a fake tcp connection
var fakeTcpConnection = server.createConnection();

// Create a rethinkdbdash connection by providing the fake tcp connection
r.connect({
  connection: fakeTcpConnection
}).bind({}).then(function(connection) {
  return r.expr('Ok').run(connection);
}).then(function(result) {
  // result === 'Ok'
}).error(function(error) {
  // Handle error
});
