configuration questions

Managing different environments in React Native typically involves using configuration files and environment variables. Libraries like `react-native-config` allow you to define environment-specific variables and load them based on the build configuration. You can use these variables to switch between different API endpoints or feature flags for development, staging, and production environments.

The MongoDB configuration file defines server settings and options for running the database instance. It specifies parameters such as port number, data directory, log file path, and replica set configurations. For example, a config file may include `storage: { dbPath: '/var/lib/mongo' }` to set the data storage location.
