Using RethinkDB in Node.js web applications
When you develop web applications of any kind, more than often, you will need a database to store data in. Without a proper persistence layer, only basic web apps can be built. In Chapter 5, Programming RethinkDB in Node.js, you learned how to connect to a RethinkDB cluster and run queries from a Node.js script. In this chapter, we're going to use the same syntax to use RethinkDB within an Express.js web app.
Fortunately, adding database connectivity capability to Express.js web apps is just a matter of loading an appropriate Node.js driver for the database in your app; however, you maybe wondering where exactly we put the code that interacts with the database, in the context of our Express.js web application. ...
