.env.sample ★ Confirmed & Top

: A developer accidentally commits the real .env file to the repository, exposing production credentials.

Before understanding .env.sample , we need to understand .env .

To address these issues, the concept of .env files emerged. A .env file is a simple text file that stores environment variables in a key-value format. By convention, .env files are placed in the root directory of your project and are not committed to version control.

Start by examining your application code for every place where process.env , $_ENV , os.getenv() , or similar methods are called. Compile a list of all environment variables your application uses. Then, create a .env.sample file in your project root with those keys and appropriate placeholder values.
