How do I set up environment variables for my project?
To set up environment variables, you can create a .env
file in your project root and define your variables there.
What format should I use in the .env file?
You should use the format VARIABLE_NAME=value
, one per line. For example: API_KEY=12345
.
How do I access these variables in my code?
You can use a library like dotenv
in Node.js to load these variables into your application.
Is it safe to store sensitive information in .env files?
Yes, but make sure to add the .env
file to your .gitignore
to prevent it from being pushed to version control.
