There are official and community-supported libraries available for various programming languages such as Node.js and Python, and integration such as RabbitMQ and ElasticSearch.

For Express.js in Node, you can use RethinkDB as a session store too; there is a module available for that, called express-session-rethinkdb.

All of these tools are listed at the official page of libraries here:https://www.rethinkdb.com/docs/frameworks-and-libraries/.
