.env Example Generator
This lesson is part of Web Developer Tools · All levels
Summary
The .env generator helps create templates of environmental variables for applications, such as API keys, database addresses, and server ports. The file .env contains the KEY=VALUE pair that the application reads when it starts. Because it often contains confidentiality, the original .env file should not be committed; the one shared with the team is the example without a sensitive value.
Key points
- The basic format of each row is KEY=VALUE with no spaces around the equals sign
- Value containing spaces should be enclosed quotation marks
- The comment row begins with the sign #
- Keep the secret in the file and insert it into the file. (.gitignore)
- Share .env.example contains variable names without secret value
