# Environment configuration
NODE_ENV=development
PORT=3000
DEV_DATABASE_URL=postgres://<your_username>:<your_password>@127.0.0.1:5432/HealthzDev
TEST_DATABASE_URL=postgres://<your_username>:<your_password>127.0.0.1:5432/HealthzTest
DATABASE_URL=postgres://<your_username>:<your_password>@127.0.0.1:5432/HealthzProduction

Step 4: Start Application

To start the application, run:

npm start

Step 5: Access the Application

Once the server is running you can open your web browser and access the application at:

http://localhost:3000
