Example .env File

Create a .env file in the root of your project with the following content:

DATABASE_URL=postgres://user:password@localhost:5432/mydb
SECRET_KEY=mysecretkey

Testing Steps

1. Install the package (if not already installed):

pip install -r requirements.txt

2. Run the CLI tool to validate the .env file:

    envguard --required DATABASE_URL --required SECRET_KEY

3. If the .env file is correct, you’ll see:

    All required environment variables are present!

4. To test missing variables, edit the .env file and remove one of the variables (e.g., SECRET_KEY). Then run the command again:

    envguard --required DATABASE_URL --required SECRET_KEY

5. You’ll see an error like this:

    Missing or incorrect environment variables:
    - SECRET_KEY
