To get started with using Node.js, CloudFoundry, and MongoDB together, one needs to sign up for a Cloud Foundry account, install local instances of MongoDB and Node.js, and configure the Cloud Foundry environment. A simple web app that records visits and provides a reporting screen can be created by writing code in JavaScript that interacts with the MongoDB database using the node-mongodb-native driver. Once the app is built and tested locally, it can be pushed to Cloud Foundry where it will automatically pick up the Node.js runtime and configure the application accordingly. The application then needs to parse environment variables to access the MongoDB service configuration and use a connection string to connect to the database. After setting up the basic functionality, additional features such as recording visits and displaying the last 10 visits can be added by creating functions that interact with the database using the node-mongodb-native driver. The app can then be tested locally and pushed to Cloud Foundry where it will run on a remote server.
