MongoDB with the Scala Driver

This is a simple implementation of a CRUD app using the official Scala Driver for Mongodb. In particular, this example was created for the MongoDB ATLAS database as a service.

Initial Configuration

You will need to create a .env file with the configuration variables in order to run the code. There is an example in the base directory of this repo called .env.example.

To create your own file run cp .env.example .env and edit the .env with your custom variables (see your ATLAS account).

Usage

There are 3 main apps in this example: Populate, Querying, Delete. The Populate app creates the collection with 100 random documents (person objects). The Querying app performs simple queries in the collection. Finally, the Delete app deletes all the documents in the collection.

1. Create your .env file: cp .env.example .env
2. Export the environment variables: source .env
3. Run the app with sbt run and select one of the following:
   • Populate: Creates the database, collection and initial objects (100).
   • Querying: Queries the existing database.
   • Delete : Deletes all objects (documents) in the collection.
