Esix makes it easy to configure your database connection for different environments (local, test, and production) using environment variables. This approach helps keep your configuration flexible and secure.

​
Database Connection Options

Here are the environment variables you can use to configure your database connection:

​
DB_ADAPTER

The adapter handles the MongoDB connection. You can choose between: Default: default

​
DB_URL

The connection URL for your MongoDB database. Default: mongodb://127.0.0.1:27017/ Example: 
DB_URL=mongodb://localhost:27017/
# or for MongoDB Atlas
DB_URL=mongodb+srv://username:password@cluster.mongodb.net/

​
DB_MAX_POOL_SIZE

The maximum number of connections in the connection pool. This helps manage database performance under load. Default: 10

​
DB_DATABASE

The name of the database to connect to. Default: (empty string) Example: 
DB_DATABASE=myapp_production

​
Setting Up Environment Variables

For local development, we recommend using the dotenv package to manage your environment variables: 
npm install dotenv
Create a .env file in your project root: 
DB_URL=mongodb://localhost:27017/
DB_DATABASE=myapp_development
DB_MAX_POOL_SIZE=5
Then load it in your application: 
import 'dotenv/config'
// Your Esix code here
⚠️ Security Note: Never commit secrets or production credentials to version control. Add .env to your .gitignore file!
