What is a .env File?
A .env file stores environment variables as key-value pairs, typically used to configure applications without hardcoding sensitive values like API keys, database URLs, and secrets into source code. It is loaded at runtime by libraries like dotenv in Node.js, python-dotenv, and similar tools in other languages.
How to Edit .env Files
Add variables with the + Add Variable button. Enter key names and values for each variable. Click Generate .env to produce the file content. Copy the output and save it as .env in your project root.
▶Should I commit .env files to Git?
No. Never commit .env files to version control. Add .env to your .gitignore. Use .env.example with placeholder values for documentation.
▶What is the .env file format?
Each line is a KEY=VALUE pair. Comments start with #. Values with spaces should be quoted: KEY="value with spaces". Empty lines are ignored.
