Why Use .env Files?

Environment variables are the standard way to manage configuration and secrets in modern applications. They keep sensitive data like API keys, database passwords, and JWT secrets out of your source code, preventing accidental exposure in version control. The .env.example file documents what variables are needed without exposing actual values, making it easy for new team members to set up the project. This tool makes creating both files fast and consistent.

Benefits

•Keep API keys and passwords out of source code
•Prevent accidental secret exposure in git commits
•Easy onboarding for new team members with .env.example
•Works with any framework or programming language
•Consistent variable naming and documentation
•Reduces setup time for new project contributors

How to Generate .env Files

1Add your environment variables using the form fields
2Enter the key name (e.g. DATABASE_URL)
3Enter the value for your local environment
4Add a comment to describe what the variable does
5Toggle 'Secret' for sensitive values like passwords and API keys
6Copy the .env file for local use and .env.example to commit to git

Best Practices for Environment Variables

Always add .env to your .gitignore file to prevent committing secrets. Use SCREAMING_SNAKE_CASE for variable names (e.g. DATABASE_URL, API_KEY). Group related variables with comments. Never hardcode secrets in your source code. Use different values for development, staging, and production environments. Consider using a secrets manager like AWS Secrets Manager or HashiCorp Vault for production.

Frequently Asked Questions

What is the difference between .env and .env.example?

.env contains actual values and should never be committed to git. .env.example shows the structure with secrets blanked out and is safe to commit.

Should I commit .env to git?

No. Add .env to your .gitignore file. Only commit .env.example.

What is the 'Secret' toggle for?

Marking a variable as Secret blanks out its value in the .env.example file, so teammates know the variable exists but don't see the actual value.

Can I use this for any framework?

Yes. .env files are supported by Node.js (dotenv), Python (python-dotenv), Next.js, React, Vue, and most modern frameworks.

How do I load .env in Node.js?

Install dotenv: npm install dotenv. Then add require('dotenv').config() at the top of your entry file. Variables are then available via process.env.KEY_NAME.
