Opening a Terminal Window

In this example we have a simple Spring Boot application that needs a running MongoDB database. We can open the terminal window with ⌥F12 (macOS) / Alt+F12 (Windows/Linux) on Windows and Linux. The terminal supports all the same commands that the operating system supports.

If we want to start the MongoDB database instance with a specific path for storing the data, we can type:

mongod --dbpath [path to data here]

and press enter. When MongoDB is running in the terminal session, we can go back to writing the application code in the editor. By using the built-in terminal, we don’t have to switch between applications, and we can easily have all aspects of our development right in front of us in the same window.
