An example of an AI chatbot conversation about using dotenv for environment variables in Node.js.
How do I use dotenv in my Node.js application?
To use dotenv, first install it using npm: npm install dotenv. Then, create a .env file for your environment variables.
What should I include in the .env file?
You can include key-value pairs like DB_HOST=localhost or API_KEY=your_api_key. Just make sure to keep it private.
How do I access these variables in my code?
You can access them using process.env.VARIABLE_NAME. For example, const dbHost = process.env.DB_HOST;.
Is there anything else I should know about using dotenv?
Yes, remember to add .env to your .gitignore file to prevent it from being pushed to version control.
