How do I use dotenv in my Node.js project?
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 project?
To use dotenv, first install it using npm: npm install dotenv. Then, create a .env file in your project root.
What should I put in the .env file?
In the .env file, you can define your environment variables like this: DB_HOST=localhost and DB_USER=root.
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 it safe to store sensitive information in .env?
Yes, it's safe as long as you don't commit your .env file to version control. Use a .gitignore file to exclude it.
