How do I use environment variables in Express.js?
An example of an AI chatbot conversation about using environment variables in Express.js.
How do I use environment variables in Express.js?
You can use the dotenv package to manage environment variables in your Express.js application. First, install it using npm.
What is the purpose of using environment variables?
Environment variables help you manage configuration settings, such as database URLs and API keys, without hardcoding them in your code.
Can you show me an example of how to set it up?
Sure! First, create a .env file in your project root and add your variables like this: DB_URL=mongodb://localhost:27017/mydb. Then, in your app, require dotenv and call config().
Is it safe to store sensitive information in the .env file?
Yes, but make sure to add the .env file to your .gitignore to prevent it from being pushed to version control.
