What are the differences between environment variables and config files in Node.js?
An example of an AI chatbot conversation about Node.js environment variables and config files.
What are the differences between environment variables and config files in Node.js?
Environment variables are used for configuration settings that can change between environments, while config files are static files that hold configuration data.
Can you give me examples of when to use each?
Sure! Use environment variables for sensitive data like API keys, and config files for application settings that don't change often.
Are there any security concerns with using config files?
Yes, config files can expose sensitive information if not properly secured. It's best to keep sensitive data in environment variables.
How can I set environment variables in a Node.js application?
You can set environment variables in your terminal before running your app, or use a package like dotenv to load them from a .env file.
