Just like the BSON databases in MongoDB, the JSON databases in RethinkDB are also schemaless. This means no blueprints and no formula or integrity constraints are imposed on the databases. No organized rule of how the database is constructed can pose the issue of integrity in our databases. Certain documents can contain different and unwanted keys in the same table (or "collection" in MongoDB), along with the documents that have the correct keys. You may inject some keys by mistake or forget to inject the required keys and values. So, it can be a good idea to enforce some sort of schema in our JSON or BSON databases if you want to keep the data in your documents organized. There is no internal feature from RethinkDB (or MongoDB) for enforcing the schema, but we can create custom functions to impose some basic schema with the Node.js Lodash module. Let's explore how to do this:
- Install the Lodash module via npm:
$ npm i lodash
- Create...
